ASTM E110-10

Designation:E110–10Standard Test Method forIndentation Hardness of Metallic Materials by Portable Hardness Testers1This standard is issued under theﬁxed designation E110;the number immediately following the designation indicates the year of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon(´)indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1This test method covers determination of the indentation hardness of metallic materials by means of portable hardness testers.1.2This test method applies only to those portable hardness testers which apply the same nominal forces and use the same indenters as are used in the methods listed in Section2.1.3This standard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1ASTM Standards:22E10Test Method for Brinell Hardness of Metallic Materials 2E18Test Methods for Rockwell Hardness of Metallic Ma-terials2E92Test Method for Vickers Hardness of Metallic Materi-als2E691Practice for Conducting an Interlaboratory Study to Determine the Precision of a Test MethodE140Hardness Conversion Tables for Metals(Relationship Among Brinell Hardness,Vickers Hardness,Rockwell Hardness,Rockwell Superﬁcial Hardness,Knoop Hard-ness,and Scleroscope Hardness)N OTE1—Test Methods E10,E18,and E92will be referred to in this test method as the“standard methods.”N OTE2—The standard methods of making the three hardness tests do not preclude the use of portable hardness testers.However,the machines usually used,and considered preferable for these tests,are generally designed so that the magnitude of the indenting force isﬁxed by dead weights acting on a small piston connected to a hydraulic loading cylinder, or by dead weights acting through a multiple lever system.Portable hardness testers of the types covered in this method do not employ dead weights toﬁx the indenting forces.This imposes certain limitations and necessitates certain precautions,which are set forth in this test method.All requirements of the standard methods except those modiﬁed by the following sections shall apply to the use of portable hardness testers. 3.Apparatus3.1Portable hardness testers are used principally for testing articles that are too large or unwieldy to be tested in the usual types of testing machines,for testing parts ofﬁxed structures, or for testing under any conditions which require that the indenting force be applied in a direction other than vertical.In order that they may be portable and also in order that the indenting forces may be applied in any direction,these testers are designed in such a way that dead weights are not used in applying or limiting the indenting force.3.2The indenting force may be applied by means of a hydraulic cylinder with a pressure gage to indicate the magni-tude of the force.The hydraulic cylinder may also be equipped with a spring-forced relief valve toﬁx the magnitude of the force.Alternatively the indenting force may be applied by means of a screw through a calibrated spring with a dial gage or other means of measuring the deﬂection of the spring to indicate the magnitude of the force.3.3Portable hardness testers are generally provided with various means of holding the indenter in contact with the surface to be tested.The testers may be clamped to the object to be tested,attached to an adjacentﬁxed object or attached to the surface to be tested by a magnet.For testing inside a cavity the tester may be placed against one wall of the cavity to makea test on the opposite wall.4.Procedure4.1Whatever means is used to hold the tester to the piece being tested,make sure that there is no relative motion between the tester and the piece when the force is applied.This is particularly true for the portable Rockwell type tester.Mount1This test method is under the jurisdiction of ASTM Committee E28onMechanical Testing and is the direct responsibility of Subcommittee E28.06onIndentation Hardness Testing.Current edition approved Jan.1,2010.Published February2010.Originallyapproved st previous edition approved in1997as E110–82(2002).DOI:10.1520/E0110-10.2For referenced ASTM standards,visit the ASTM website,,orcontact ASTM Customer Service at service@.For Annual Book of ASTMStandards volume information,refer to the standard’s Document Summary page onthe ASTM website.1Copyright C ASTM International,100Barr Harbor Drive PO box C-700West Conshohocken,Pennsylvania19428-2959,United Statesthe tester in such a position that the axis of the indenter is normal to the surface to be tested.4.2Application of Force,Portable Brinell Test—Portable Brinell testers generally apply the force by means of a hydraulic cylinder equipped with both a pressure gage and a spring forced relief valve.With this arrangement it is not possible to maintain the force at the point where the relief valve opens for any appreciable time.Therefore bring up the force several times to the point where the pressure is released.It has been determined that for steel,when testing with a3000-kgfforce,three force applications are equivalent to holding the force15s as required in the standard method.For other materials and other forces,make comparison tests to determine the number of force applications required to give results equivalent to the standard method.Bring the force up gradually each time without jerking.4.3Application of Force,Portable Rockwell Type Test—Portable Rockwell type testers generally apply the force through a calibrated spring by means of a screw and are generally equipped with two indicators,one a dial gage that measures deﬂection of the spring to indicate the force,and the other a dial gage or micrometer screw to indicate the depth of penetration.Apply the preliminary test force as shown by the force indicator.Set the index on the depth indicator to the proper point.Then apply the total test force.Turn the loading screw in the opposite direction until the preliminary test force is again indicated on the force dial.Then read the hardness on the depth indicator as the difference between the readings at the minor force before and after application of the major force. Bring the force up gradually without jerking.Exercise care not to exceed either the preliminary or the total test forces. Complete the removal of the total test force within2s after it has been completely applied.4.4Application of Force,Vickers Type Tester—Portable Vickers type testers generally apply the force by means of a hydraulic cylinder equipped with a pressure gage.Bring the indenter just in contact with the test surface and check the zero reading of the pressure gage.Then bring the force up to the required value as shown on the pressure gage.Bring the force up gradually without jerking and take care that the required force is not overrun.Maintain the full force for at least15s, unless otherwise speciﬁed,and then release.5.Calibration of Apparatus5.1Portable hardness testers shall be used only with applied forces at which the force measuring device has been calibrated.5.2Portable hardness testers shall also be checked for error periodically by the comparison method or by test blocks as described in the standard methods.6.Precision and Bias6.1A precision and bias study was conducted in late 2007/early2008in accordance with Practice E691to determine the precision of Rockwell and Brinell test results obtained with portable hardness testers.Because of the difference in the equipment used,the Rockwell and Brinell testing were treated as two separate studies.The full results areﬁled under ASTM Research Report RR:E28-1043.36.2Seven laboratories were used for each study.Three of the laboratories were manufacturers of portable hardness testers and four were users of the equipment.The testing for ﬁve of the laboratories was done at the November2008ASTM meeting in Tampa,Florida.The remainders were done at the users’facilities.In some cases the testing was done by calibration agency personal.6.3Separate studies were done for Rockwell and Brinell portable hardness testers.6.3.1For the Rockwell scale testing,four different types of portable hardness testers were used that were produced by three manufacturers.Some testers were new and some were older and well used.6.3.2The Brinell tests were all performed on testers from one manufacturer since it is by far the most commonly used by industry.The seven portable hardness testers used for the Brinell testing ranged from new to30years old.Five different measuring systems were used to determine the size of the Brinell indent.Two were computer-controlled systems and the others were manual hand-held scopes with20X magniﬁcation from three different manufacturers.6.4The E110-82(2002)version of the standard was current at the time of the study.Since the standard did not clearly specify that an indirect veriﬁcation of the testers was required, no attempt was made to qualify them by verifying their overall performance on test blocks before using them in the study.All of the portable hardness testers used for the testing were considered to be in good working order and typical of those used for everyday testing.6.5The hardness tests were made on standardized test blocks calibrated according to E18-07or E10-07.The Rock-well HRC and HRBW and the Brinell HBW10/3000scales were used.For each scale,three test blocks were used,one each in the high,medium,and low hardness ranges.Three tests were performed on each test block in speciﬁc locations.6.6A summary of the test data is shown in Table1and Table2below.6.6.1The value of r PB indicates the typical amount of variation that can be expected between test results obtained for the same material by the same operator using the same hardness tester on the same day.When comparing two test results made under these conditions,a measurement difference

under these conditions,a measurement differenceof less than the R PB value for that material is an indication that the results may be equivalent.6.6.3Any judgments based on the results would have an approximate 95%probability of being correct.6.6.4Although the precision values given in Table 1and Table 2provide guidance on interpreting differences in mea-surement results,a complete evaluation of

HGP轻载上行报E110故障的处理经验

HGP轻载上行报E110故障的处理经验
电梯轻载上行时，长站运行会出现电梯超平层现象，偶尔会报E110故障死机，下行运行正常。

更换10T、10TA、MCUB板、RYBD板、变频器、制动单元、光电感应器FMLXY，问题都未能彻底解决。

发现电梯轻载上行时的确存在超平层现象，且超平层严重时会出现死机自救现象。

查阅电梯故障码，有报E93、E55、E64故障。

1、对正常梯核对变频器参数，变频器参数未发现异常。

2、屏蔽微动平层与平层预开门功能，试运行电梯，依然会出现超平层现象，并且期间出现E110故障。

说明故障与FMLXY无关。

恢复微动平层以及平层预开门功能。

3、怀疑磁极码不准确。

重新测量磁极码，发现最佳磁极码比出厂的磁极码要大80度。

重新写入测量的磁极码，观察电梯运行，未发现异常。

问题的真正原因是旋转编码器没有紧固，在运行一段时间后磁极码会发生改变，导致电梯超平层，电梯在超平层的情况下，可能会引致110故障死机。

ASTM E110-10

Designation:E110–10Standard Test Method forIndentation Hardness of Metallic Materials by Portable Hardness Testers1This standard is issued under theﬁxed designation E110;the number immediately following the designation indicates the year of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon(´)indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1This test method covers determination of the indentation hardness of metallic materials by means of portable hardness testers.1.2This test method applies only to those portable hardness testers which apply the same nominal forces and use the same indenters as are used in the methods listed in Section2.1.3This standard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1ASTM Standards:22E10Test Method for Brinell Hardness of Metallic Materials 2E18Test Methods for Rockwell Hardness of Metallic Ma-terials2E92Test Method for Vickers Hardness of Metallic Materi-als2E691Practice for Conducting an Interlaboratory Study to Determine the Precision of a Test MethodE140Hardness Conversion Tables for Metals(Relationship Among Brinell Hardness,Vickers Hardness,Rockwell Hardness,Rockwell Superﬁcial Hardness,Knoop Hard-ness,and Scleroscope Hardness)N OTE1—Test Methods E10,E18,and E92will be referred to in this test method as the“standard methods.”N OTE2—The standard methods of making the three hardness tests do not preclude the use of portable hardness testers.However,the machines usually used,and considered preferable for these tests,are generally designed so that the magnitude of the indenting force isﬁxed by dead weights acting on a small piston connected to a hydraulic loading cylinder, or by dead weights acting through a multiple lever system.Portable hardness testers of the types covered in this method do not employ dead weights toﬁx the indenting forces.This imposes certain limitations and necessitates certain precautions,which are set forth in this test method.All requirements of the standard methods except those modiﬁed by the following sections shall apply to the use of portable hardness testers. 3.Apparatus3.1Portable hardness testers are used principally for testing articles that are too large or unwieldy to be tested in the usual types of testing machines,for testing parts ofﬁxed structures, or for testing under any conditions which require that the indenting force be applied in a direction other than vertical.In order that they may be portable and also in order that the indenting forces may be applied in any direction,these testers are designed in such a way that dead weights are not used in applying or limiting the indenting force.3.2The indenting force may be applied by means of a hydraulic cylinder with a pressure gage to indicate the magni-tude of the force.The hydraulic cylinder may also be equipped with a spring-forced relief valve toﬁx the magnitude of the force.Alternatively the indenting force may be applied by means of a screw through a calibrated spring with a dial gage or other means of measuring the deﬂection of the spring to indicate the magnitude of the force.3.3Portable hardness testers are generally provided with various means of holding the indenter in contact with the surface to be tested.The testers may be clamped to the object to be tested,attached to an adjacentﬁxed object or attached to the surface to be tested by a magnet.For testing inside a cavity the tester may be placed against one wall of the cavity to makea test on the opposite wall.4.Procedure4.1Whatever means is used to hold the tester to the piece being tested,make sure that there is no relative motion between the tester and the piece when the force is applied.This is particularly true for the portable Rockwell type tester.Mount1This test method is under the jurisdiction of ASTM Committee E28onMechanical Testing and is the direct responsibility of Subcommittee E28.06onIndentation Hardness Testing.Current edition approved Jan.1,2010.Published February2010.Originallyapproved st previous edition approved in1997as E110–82(2002).DOI:10.1520/E0110-10.2For referenced ASTM standards,visit the ASTM website,,orcontact ASTM Customer Service at service@.For Annual Book of ASTMStandards volume information,refer to the standard’s Document Summary page onthe ASTM website.1Copyright C ASTM International,100Barr Harbor Drive PO box C-700West Conshohocken,Pennsylvania19428-2959,United Statesthe tester in such a position that the axis of the indenter is normal to the surface to be tested.4.2Application of Force,Portable Brinell Test—Portable Brinell testers generally apply the force by means of a hydraulic cylinder equipped with both a pressure gage and a spring forced relief valve.With this arrangement it is not possible to maintain the force at the point where the relief valve opens for any appreciable time.Therefore bring up the force several times to the point where the pressure is released.It has been determined that for steel,when testing with a3000-kgfforce,three force applications are equivalent to holding the force15s as required in the standard method.For other materials and other forces,make comparison tests to determine the number of force applications required to give results equivalent to the standard method.Bring the force up gradually each time without jerking.4.3Application of Force,Portable Rockwell Type Test—Portable Rockwell type testers generally apply the force through a calibrated spring by means of a screw and are generally equipped with two indicators,one a dial gage that measures deﬂection of the spring to indicate the force,and the other a dial gage or micrometer screw to indicate the depth of penetration.Apply the preliminary test force as shown by the force indicator.Set the index on the depth indicator to the proper point.Then apply the total test force.Turn the loading screw in the opposite direction until the preliminary test force is again indicated on the force dial.Then read the hardness on the depth indicator as the difference between the readings at the minor force before and after application of the major force. Bring the force up gradually without jerking.Exercise care not to exceed either the preliminary or the total test forces. Complete the removal of the total test force within2s after it has been completely applied.4.4Application of Force,Vickers Type Tester—Portable Vickers type testers generally apply the force by means of a hydraulic cylinder equipped with a pressure gage.Bring the indenter just in contact with the test surface and check the zero reading of the pressure gage.Then bring the force up to the required value as shown on the pressure gage.Bring the force up gradually without jerking and take care that the required force is not overrun.Maintain the full force for at least15s, unless otherwise speciﬁed,and then release.5.Calibration of Apparatus5.1Portable hardness testers shall be used only with applied forces at which the force measuring device has been calibrated.5.2Portable hardness testers shall also be checked for error periodically by the comparison method or by test blocks as described in the standard methods.6.Precision and Bias6.1A precision and bias study was conducted in late 2007/early2008in accordance with Practice E691to determine the precision of Rockwell and Brinell test results obtained with portable hardness testers.Because of the difference in the equipment used,the Rockwell and Brinell testing were treated as two separate studies.The full results areﬁled under ASTM Research Report RR:E28-1043.36.2Seven laboratories were used for each study.Three of the laboratories were manufacturers of portable hardness testers and four were users of the equipment.The testing for ﬁve of the laboratories was done at the November2008ASTM meeting in Tampa,Florida.The remainders were done at the users’facilities.In some cases the testing was done by calibration agency personal.6.3Separate studies were done for Rockwell and Brinell portable hardness testers.6.3.1For the Rockwell scale testing,four different types of portable hardness testers were used that were produced by three manufacturers.Some testers were new and some were older and well used.6.3.2The Brinell tests were all performed on testers from one manufacturer since it is by far the most commonly used by industry.The seven portable hardness testers used for the Brinell testing ranged from new to30years old.Five different measuring systems were used to determine the size of the Brinell indent.Two were computer-controlled systems and the others were manual hand-held scopes with20X magniﬁcation from three different manufacturers.6.4The E110-82(2002)version of the standard was current at the time of the study.Since the standard did not clearly specify that an indirect veriﬁcation of the testers was required, no attempt was made to qualify them by verifying their overall performance on test blocks before using them in the study.All of the portable hardness testers used for the testing were considered to be in good working order and typical of those used for everyday testing.6.5The hardness tests were made on standardized test blocks calibrated according to E18-07or E10-07.The Rock-well HRC and HRBW and the Brinell HBW10/3000scales were used.For each scale,three test blocks were used,one each in the high,medium,and low hardness ranges.Three tests were performed on each test block in speciﬁc locations.6.6A summary of the test data is shown in Table1and Table2below.6.6.1The value of r PB indicates the typical amount of variation that can be expected between test results obtained for the same material by the same operator using the same hardness tester on the same day.When comparing two test results made under these conditions,a measurement difference

approximate 95%probability of being correct.6.6.4Although the precision values given in Table 1and Table 2provide guidance on interpreting differences in mea-surement results,a complete evaluation of

e110锆合金中第二相的显微结构与演变规律

e110锆合金中第二相的显微结构与演变规律E110锆合金是一种高温合金，最初由埃克尔公司开发，并成功制备出具有良好物理和力学性能的微晶组织。

锆合金加工工艺中最常见的相组成为γ相、α相和α+γ相，其中第二相的微观结构和演变规律分别是：
①γ相，γ相的晶粒主要以小颗粒状，颗粒大小约1-10μm，具有较好的可塑性，孔隙较多，这种类型微观结构可以维持锆合金熔点低，片状特性良好，同时具有良好的冲击韧性和抗突变性能。

②α相，对α相，其基体由γ锆形成，形貌表现为晶界网状结构，穿过基体的α锆晶粒大小约为4-100μm，其特性与γ相相似，但比γ相更硬和更韧，表现出良好的高温力学性能，并具有较高的耐磨性能和优良的耐腐蚀性能。

③α+γ相，α+γ相对于γ相和α相，它的晶粒大小介于二者之间，相较于γ相和α相的组合，其具有良好的热力学性能，具有更好的抗蠕变性、高温强度、高温软化性和良好的耐氧化性能。

在熔点升高过程中，γ相最初衰变变相生成α相。

之后，随着熔点的进一步升高，随着γ晶粒逐渐减小，α相继续增长，最终混合γ+α相。

经过熔点提高后，α+γ相会增大，γ+α相会逐渐衰变，当熔点接近其最高值时，α+γ相会相对均匀地分布在基体中。

食用色素与好动

食用色素与好动如果你的孩子有好动或者注意缺陷多动障碍（ADHD），那么减少孩子食用色素的摄入可能有所改善。

这些食用色素包括：日落黄(E110)、喹啉黄(E104)、偶氮玉红/淡红(E122)、诱惑红(E129)、酒石黄(E102)、丽春花红(E124)，以上食用色素被大量用于食物加工中，包括一些软饮、甜点、蛋糕、冰淇淋等的加工制作。

每种食用色素后面以E开头的编号是什么意思呢？所有天然或者人工食品添加剂，在生产上市前都必须经过严格的评估考察，获得生产许可，有的还得经过欧盟认证。

言下之意是，只有当它们被鉴定为必须且对人体绝对安全时才允许生产。

因此若一种食品添加剂后面有E开头的编号，说明它经过了质检且成功通过食品认证，对人体是安全的。

只要食品中添加了食用色素，则厂家必须在成分表里标明，附上该食用色素名称或编号。

如果是在食品或者饮料中添加了上述6种色素之一，最好能标明“本品可能会造成儿童注意力缺陷及有导致儿童好动的风险”。

因此通过仔细阅读成分表可避免购买含以上食用色素的食品，如果你买的食品没有外包装，则需查询生产厂家或咨询经销商。

随着人们对食品安全的关注度日益提高，很多生产厂家也在积极寻找食用色素的天然代替物，其中一些厂家和零售商已经去除了上述食用色素的添加。

此外，除了引起儿童注意力不集中和多动障碍以外，某些食品添加剂（如亚硫酸盐类）还可引起机体过敏反应。

好动与注意缺陷多动障碍（多动症）区别：好动是指孩子活动过度，注意力不能集中，没心思考虑其它代替方法，想到立马就冲动地去做。

专家认为儿童中有2-5%的比例有多动，目前并没有特异性的检查或量表来诊断。

值得一提的是，很多因素都与多动有关，比如早产、遗传、家庭教育等。

而注意缺陷多动障碍就不仅仅是好动了，它常常表现为与年龄和发育水平不相称的注意力不集中和注意时间短暂、活动过度和冲动，常伴有学习困难、品行障碍和适应不良，会明显影响儿童学业、身心健康以及成年后的家庭生活和社交能力。
