ASTM 铜片腐蚀测定法

Designation:D130–94(Reapproved2000)e1(21262°F),or both,and having suitable supports to hold the test tubes in a vertical position and immersed to a depth of about 100mm (4in.).Either water,oil,or aluminum block baths are suitable.5.2Copper Strip Corrosion Test Bomb ,constructed of stainless steel according to the dimensions as given in Fig.1,and capable of withstanding a test pressure of 100psi (689kPa).Alternative designs for the bomb cap and synthetic rubber gasket may be used provided that the internal dimen-sions of the bomb are the same as those shown in Fig.1.Provide a 25by 150-mm test tube as a liner for holding the sample.5.2.1Provide liquid baths capable of being maintained at 4061°C (10462°F)or 10061°C (21262°F),or both,and having suitable supports to hold the test bomb in a vertical position.The bath must be deep enough so that the entire bomb will be submerged during the test.As the bath medium,use water or any other liquid which can be satisfactorily controlled at the speciﬁed test temperature.5.3Thermometers ,total immersion,for indicating the re-quired test temperature,with smallest graduations of 1°C (2°F)or less.No more than 25mm (1in.)of the mercury thread should extend above the surface of the bath at the test temperature.The ASTM 12C (12F)or IP 64C (64F)thermom-eter is suitable.5.4Polishing Vise ,for holding the copper strip ﬁrmly without marring the edges while polishing.Any convenient type of holder (see Appendix)may be used provided that the strip is held tightly and that the surface of the strip being polished is supported above the surface of the holder.5.5Viewing Test Tubes ,ﬂat glass test tubes,are convenient for protecting corroded strip for close inspection or storage (see Appendix).6.Materials6.1Wash Solvent —Any volatile,sulfur-free hydrocarbon solvent may be used provided that it shows no tarnish at allwhen tested at 50°C (122°F).Knock test grade iso octane is a suitable solvent and should be used in case of dispute.(Warning —Extremely ﬂammable,see A2.1.)6.2Polishing Materials —Silicon carbide grit paper of vary-ing degrees of ﬁneness including 65-µm (240-grit)paper or cloth;also a supply of 105-µm (150-mesh)silicon carbide grain and pharmaceutical grade absorbent cotton (cotton wool).6.3Copper Strips :6.3.1Speciﬁcation —Use strips 12.5mm (1⁄2in.)wide,1.5to 3.0mm (1⁄16to 1⁄8in.)thick,cut 75mm (3in.)long from smooth-surfaced,hard-temper,cold-ﬁnished copper of 99.9+%purity;electrical bus bar stock is generally suitable (see Appendix).The strips may be used repeatedly but should be discarded when the surfaces become deformed on handling.6.3.2Surface Preparation —Remove all surface blemishes from all six sides of the strip with silicon carbide paper of such degrees of ﬁneness as are needed to accomplish the desired results efficiently.Finish with 65-µm (240-grit)silicon carbide paper or cloth,removing all marks that may have been made by other grades of paper used previously.Immerse the strip in wash solvent from which it can be withdrawn immediately for ﬁnal preparation (polishing)or in which it can be stored for future use.6.3.2.1As a practical manual procedure for surface prepa-ration,place a sheet of the paper on a ﬂat surface,moisten it with kerosine or wash solvent,and rub the strip against the paper with a rotary motion,protecting the strip from contact with the ﬁngers with an ashless ﬁlter paper.Alternatively,the surface of the strip can be prepared by use of motor-driven machines using appropriate grades of dry paper or cloth.6.3.3Final Preparation —Remove a strip from the wash solvent.Holding it in the ﬁngers protected with ashless ﬁlter paper,polish ﬁrst the ends and then the sides with the 105-µm (150-mesh)silicon carbide grains picked up from a clean glass plate with a pad of cotton (cotton wool)moistened with a drop of wash solvent.Wipe vigorously with fresh pads of cotton (cotton wool)and subsequently handle only with stainless steel forceps;do not touch with the ﬁngers.Clamp in a vise and polish the main surfaces with silicon-carbide grains on absor-bent cotton.Do not polish in a circular motion.Rub in the direction of the long axis of the strip,carrying the stroke beyond the end of the strip before reversing the direction.Clean all metal dust from the strip by rubbing vigorously with clean pads of absorbent cotton until a fresh pad remains unsoiled.When the strip is clean,immediately immerse it in the prepared sample.6.3.3.1It is important to polish the whole surface of the strip uniformly to obtain a uniformly stained strip.If the edges show wear (surface elliptical)they will likely show more corrosion than the center.The use of a vise (see Appendix)will facilitate uniform polishing.6.3.3.2It is important to follow the order of preparation with the correctly sized silicon carbide material as described in 6.3.2and 6.3.3.The ﬁnal preparation is with 105-µm silicon carbide grains.This is a larger grain size than the 65micron paper used in the surface preparation stage.The reason for this use of larger silicon carbide grains in the ﬁnal preparation is to produce asperities (controlled roughness)on the surface oftheFIG.1Copper Strip Corrosion TestBombcopper which acts as sites for the initiation of corrosion reactions.7.Corrosion Standards7.1ASTM Copper Strip Corrosion Standards 4consist of reproductions in color of typical test strips representing in-creasing degrees of tarnish and corrosion,the reproductions being encased in plastic in the form of a plaque.7.1.1Keep the plastic-encased printed ASTM Copper Strip Corrosion Standards protected from light to avoid the possi-bility of fading.Inspect for fading by comparing two different plaques,one of which has been carefully protected from light (new).Observe both sets in diffused daylight (or equivalent)ﬁrst from a point directly above and then from an angle of 45°.When any evidence of fading is observed,particularly at the left-hand end of the plaque,it is suggested that the one that is the more faded with respect to the other be discarded.7.1.1.1Alternatively,place a 20-mm (3⁄4-in.)opaque strip (masking tape)across the top of the colored portion of the plaque when initially purchased.At intervals remove the opaque strip and observe.When there is any evidence of fading of the exposed portion,it is suggested that the standards be replaced.7.1.1.2These plaques are full-color reproductions of typical strips.They have been printed on aluminum sheets by a 4-color process and are encased in plastic for protection.Directions for their use are given on the reverse side of each plaque.7.1.2If the surface of the plastic cover shows excessive scratching it is suggested that the plaque be replaced.8.Samples8.1It is particularly important that all types of fuel samples,which pass a low-tarnish strip classiﬁcation,be collected in clean,dark glass bottles,plastic bottles,or other suitable containers that will not affect the corrosive properties of the fuel.Avoid the use of tin plate containers for collection of samples,since experience has shown that they may contribute to the corrosiveness of the sample.8.2Fill the containers as completely as possible and close them immediately after taking the sample.Take care during sampling to protect the samples from exposure to direct sunlight or even diffused daylight.Make the test as soon as possible after receipt in the laboratory and immediately after opening the container.8.3When suspended water (haze)is observed in the sample,dry by ﬁltering a sufficient volume of sample through a medium rapid qualitative ﬁlter,into the prescribed clean,dry test tube.Carry out this operation in a darkened room or under a light-protected shield.8.3.1Contact of the copper strip with water before,during,or after the completion of the test run,will cause staining,making it difficult to evaluate the strips.9.Procedure9.1Those product classes,to which given procedural varia-tions are intended to be applied,are listed below.Some productclasses,being quite broad,may be tested by more than one set of conditions;in such cases the copper strip quality require-ment for a given product should be limited to a single set of conditions.The conditions of time and temperature given below are those most commonly used and are quoted in the ASTM speciﬁcations for these products where such speciﬁca-tions exist.However,other conditions can also be used as and when required by speciﬁcations or by agreement between parties.9.1.1For aviation gasoline,and aviation turbine fuel —Place 30mL of sample,completely clear and free of any suspended or entrained water (see 8.3)into a chemically clean,dry 25by 150-mm test tube,and within 1min after completing the ﬁnal preparation (polishing),slide the copper strip into the sample tube.Carefully slide the sample tube into the test bomb (Fig.1)and screw the lid on pletely immerse the bomb in a boiling water bath at 10061°C (21262°F).After 2h 65min in the bath,withdraw the bomb and immerse for a few minutes in tap water.Open the bomb,withdraw the test tube and examine the strip as described in 9.2.9.1.2For natural gasoline —Carry out the test exactly as described in 9.1.1but at 40°C (104°F)and for 3h 65min.9.1.3For diesel fuel,fuel oil,automotive gasoline —Place 30mL of sample,completely clear and free of any suspended or entrained water (see 8.3),into a chemically clean,dry 25by 150-mm test tube and,within 1min after completing the ﬁnal preparation (polishing),slide the copper strip into the sample tube.Stopper with a vented cork and place in a bath maintained at 5061°C (12262°F)(see 5.1.1).Protect the contents of the test tube from strong light during the test.After 3h 65min in the bath,examine the strip as described in 9.2.For tests on fuel oil and diesel fuel,to speciﬁcations other than Speciﬁcations D 396and D 975,a temperature of 100°C (212°F)for 3h is often used as an alternative set of conditions.9.1.4For cleaners (Stoddard)solvent and kerosine —Carry out the test exactly as described in 9.1.3but at 10061°C (21262°F).9.1.5For lubricating oil —Tests can be carried out for varying times and at elevated temperatures other than 100°C (212°F).For the sake of uniformity,it is suggested that even increments of 50°F beginning with 250°F (or Celsius equiva-lents to the nearest whole degree)be used.9.2Strip Examination :9.2.1Empty the contents of the test tube into a 150-mL tall-form beaker,letting the strip slide in gently so as to avoid breaking the beaker.Immediately withdraw the strip with stainless steel forceps and immerse in wash solvent.Withdraw the strip at once,dry with quantitative ﬁlter paper (by blotting and not by wiping),and inspect for evidences of tarnishing or corrosion by comparison with the Copper Strip Corrosion Standards.Hold both the test strip and the standard strip plaque in such a manner that light reﬂected from them at an angle of approximately 45°will be observed.9.2.2In handling the test strip during the inspection and comparison,the danger of marking or staining can be avoided if it is inserted in a ﬂat glass tube (see Appendix X1)which can be stoppered with absorbent cotton.4Conforming to Copper Development Assn.(CDA),United States of America No.110,or to British Standard (BS)1036:1952,which have properquality.10.Interpretation10.1Interpret the corrosiveness of the sample accordingly as the appearance of the test strip agrees with one of the strips of the ASTM Copper Strip Corrosion Standards.10.1.1When a strip is in the obvious transition state between that indicated by any two adjacent standard strips,judge the sample by the more tarnished Standard Strip.Should a strip appear to have a darker orange color than Standard Strip 1b ,consider the observed strip as still belonging in Classiﬁca-tion 1;however,if any evidence of red color is observed,the observed strip belongs in Classiﬁcation 2.10.1.2A claret red strip in Classiﬁcation 2can be mistaken for a magenta overcast on brassy strip in Classiﬁcation 3if the brassy underlay of the latter is completely masked by a magenta overtone.To distinguish,immerse the strip in wash solvent;the former will appear as a dark orange strip while the latter will not change.10.1.3To distinguish multicolored strips in Classiﬁcations 2and 3,place a test strip in a 20by 150-mm test tube and bring to a temperature of 315to 370°C (600to 700°F)in 4to 6min with the tube lying on a hot plate.Adjust to temperature by observing a high distillation thermometer inserted into a second test tube.If the strip belongs in Classiﬁcation 2,it willassume the color of a silver and then a gold strip,if in Classiﬁcation 3it will take on the appearance of a transparent black,etc.,as described in Classiﬁcation 4.10.1.4Repeat the test if blemishes due to ﬁnger prints are observed,or due to spots from any particles of water droplets that may have touched the test strip during the digestion period.10.1.5Repeat the test also if the sharp edges along the ﬂat faces of the strip appear to be in a classiﬁcation higher than the greater portion of the strip;in this case it is likely that the edges were burnished during preparation (polishing).11.Report11.1Report the corrosiveness in accordance with one of the classiﬁcations listed in Table 1.State the duration of the test and the test temperature.12.Precision and Bias12.1In the case of pass/fail data no generally accepted method for determining precision or bias is currently available.13.Keywords13.1automotive gasoline;aviation gasoline;aviation tur-bine fuel;copper corrosion;copper strip ﬁnish;corrosiveness to copper;natural gasolineTABLE 1Copper Strip

3、测定原理：一定量的试样与无水溶剂混合，进行蒸馏测定其水分含量用百分数表示。

GB/T 260-77(88)《石油产品水分测定法》是一种蒸馏法。

将一定量的试油和溶剂（沸点在100 ℃左右）混合，在规定的水分测定器中进行蒸馏。

加入的溶剂降低了试验的粘度，可避免含水试油沸腾时引起冲击和起泡现象。

蒸馏时加入的溶剂和水一起沸腾并蒸出，可将试油中含有的水携带出来，经冷凝后冷凝液流入接受器中。

由于水的密度比溶剂的密度大，水分就可以沉降到接受器的下部，接受器上部的溶剂返回蒸馏瓶。

随着不断地蒸馏，水分不断被溶剂携带出来，不断沉降到水分接受器下部。

根据试油的量和蒸出的水分的体积，可以计算出试样中含水的百分数，作为石油产品所含水分的测定结果。

3.1水在燃料油和润滑油中存在的状态：(1)游离状：析出的微小水粒聚集成较大颗粒从油品中沉降下来，呈油水分离状态存在。

(2)悬浮状：水分以水滴形态悬浮于油中，多发生于粘度较大的重油。

(3)乳化悬浮状：水分以极细小的水粒状态均匀分散在油中，这种分散很细的乳浊液，由于水滴微粒极小，比悬浮状的水分更难除去。

(4)溶解状：以水分子状态存在于油品烃类分子空隙间，与烃类呈均相。

液化石油气铜片腐蚀试验法

液化石油气铜片腐蚀试验法
一、概述
铜片腐蚀：在规定条件下，测试液化石油气对铜的腐蚀趋向的试验。

液化石油气的铜片腐蚀试验，主要是测定液化石油气的腐蚀性程度。

因为液化石油气在储运及使用过程中，均采用金属容器罐装，如果液化石油气腐蚀性过强，就会造成储运设备，容器的严重腐蚀，致使缩短使用期限，甚至引发其他危险。

因此，这项试验有重要意义。

我国现行的液化石油气铜片腐蚀试验法是采用SH／T 0232《液化石油气铜片腐蚀试验法》，该方法等效采用ISO 6521-1982《液化石油气铜片试验法》。

二、原理
将磨光的铜片，全部浸入装有100mL已被水饱和的试样的容器中，该容器应具有一定的工作压力(≥7.0MPa)，在40℃温度下放置1h，取出后与标准色板比较，判断其腐蚀级别。

石油产品铜片腐蚀性测试仪实验方法

石油产品铜片腐蚀性测试仪实验方法铜片腐蚀设备用于测定柴油、汽油、润滑油或其他石油产品对铜的腐蚀性程度(本方法涉及到易燃材料,操作时要注意安全)。

注意：本方法涉及到易燃材料,操作前要注意试样的燃点、闪点,操作时要注意安全铜片腐蚀设备主要部件。

一、水浴：能够维持在试验所需要的温度40、50、100±1℃、LED 显示温度，按键式控制。

用于确认输入值用于设定温度时改变数值的位数二、试验弹：按照ASTM D130 标准制造，用于部分油品测试(如:航空汽油等)，内有橡胶垫圈，保持好的密封性。

三、试验试管：按照ASTM D130 标准制造,用于部分易挥发油品测试(如润滑油等)。

四、磨片夹具：磨片时可以牢固的夹住铜片，且不损坏边缘。

五、观察试管及试管固定夹：试验结束时，可以更方便的观察铜片的腐蚀状况。

六、砂纸及砂粒：240目、600目等颗粒粗细不同的磨光砂纸。

七、铜片：纯度大于99.9%的电解铜。

八、腐蚀标准色板：按照ASTM D130标准制造的标准色板，磨光后的铜片在油品中腐蚀后的可参照标准色板的腐蚀等级来判定油品的腐蚀性，铜片腐蚀标准色板要避光保存。

九、观察试管：扁平的观察试管更易观察变色或腐蚀迹象，除铜片腐蚀设备的部件外，还需准备滤纸、脱脂棉、试样、洗涤溶剂（在50℃，试验3小时不使铜片变色的任何易挥发、无硫烃类溶剂均可，如异辛烷、石油醚等）。

铜片的准备：1、用夹具纵向夹紧铜片，先用比较粗的砂纸（目数越低砂纸越粗）把铜片的瑕疵去掉，可来回调换夹具上铜片的方向，使铜片的六个面上所有部位上的瑕疵和以前打磨的痕迹都去掉，打磨完后可以用定量的滤纸擦去铜片上的金属屑，此时可以把铜片放入洗涤溶剂中清洗后擦干再进行最后磨光，也可以直接进行最后磨光，打磨的铜片均要拿镊子或滤纸来拿，不可以用手触摸。

2、用目数较高的砂纸打磨铜片或用蘸了砂粒的脱脂棉打磨铜的表面，磨时尽量沿铜片的长轴方向打磨。

3、在铜片打磨光亮后用脱脂棉擦去金属屑，铜片擦干净后放入准备好的试样中。

汽油铜片腐蚀试验实训指导

任务2-5 汽油铜片腐蚀试验实训指导一、实施目的（1）掌握铜片腐蚀试验的测定[GB/T 5096《石油产品铜片腐蚀试验法》]原理与试验方法。

（2）熟悉金属试片制备过程与技术。

二、仪器材料试验弹；试管（长150mm、外径25mm、壁厚1～2mm，在试管30mL处刻一环线）；水浴或其它液体浴(或铝块浴)；磨片夹钳或夹具；观察试管（扁平形，在试验结束时，供检验用或在贮存期间供盛放腐蚀的铜片用）；温度计（全浸型、最小分度1℃或小于1℃，供指示所需的试验温度用，所测温度点的水银线伸出浴介质表面应不大于25mm）。

铜片腐蚀试验弹1—“0”形密封圈；2—提环；3—压力释放槽；4—滚花帽；5—细牙螺纹；6—密封圈保护槽；7—无缝不锈钢管三、所用试剂洗涤溶剂（异辛烷或分析纯的石油醚，90～120℃）；铜片；磨光材料（砂纸或砂布)。

四、准备工作（1）试片的制备①表面准备：为了有效地达到预期的结果，需先用碳化硅或氧化铝(刚玉)砂纸(或砂布)把铜片六个面上的瑕疵去掉。

再用65μm(240粒度)的碳化硅或氧化铝(刚玉)砂纸(或砂布)处理，以除去在此以前用其它等级砂纸留下的打磨痕迹。

用定量滤纸擦去铜片上的金属屑后，把铜片浸没在洗涤溶剂中。

铜片从洗涤溶剂中取出后，可直接进行最后磨光，或贮存在洗涤溶剂中备用。

表面准备的操作步骤：把一张砂纸放在平坦的表面上，用煤油或洗涤溶剂湿润砂纸，以旋转动作将铜片对着砂纸摩擦，用无灰滤纸或夹钳夹持，以防止铜片与手指接触。

另一种方法是用粒度合适的干砂纸(或砂布)装在马达上，通过驱动马达来加工铜片表面。

②最后磨光：从洗涤溶剂中取出铜片，用无灰滤纸保护手指来夹拿铜片。

取一些105μm(150目)的碳化硅或氧化铝(刚玉)砂粒放在玻璃板上，用1滴洗涤溶剂湿润，并用一块脱脂棉，蘸取砂粒。

用不锈钢镊子夹持铜片，千万不能接触手指。

先摩擦铜片各端边，然后将铜片夹在夹钳上，用沾在脱脂棉上的碳化硅或氧化铝(刚玉)砂粒磨光主要表面。
