MIL-STD-1916抽样标准简介(定稿)

MIL-STD-1916抽样标准简介(定稿)

MIL-STD-1916抽樣標準簡介盤天培、楊義明中山科學研究院一、前言:為強調製程品管與持續不斷改進之重要性,美軍於1996年推出新版的抽樣標準:MIL-STD-1916,用以取代MIL-STD-105E 作為美軍採購時主要選用之抽樣標準。

本標準之目的在鼓勵供應商建立品質系統與使用有效的製程管制程序,以取代最終產品之抽樣方式,希望供應商遠離以AQL(Acceptable Quality Level)為主之抽樣計畫,而以預防性的品質制度代替之。

故本標準之願景在建立不合格件製程改進之制度,而非最終檢驗之品質水準。

MIL-STD-1916與MIL-STD-105E抽樣標準不同之處,主要有下列有幾點:1.抽樣計畫以單次抽樣(含加嚴、正常及減量)為主,刪除雙次與多次抽樣,抽樣以『0收1退』(ZBA,Zero BasedAcceptance)當做判定標準,強調不允許不良品之存在。

2.建立持續不斷改善之品質系統制度與善用多項品質改善工具。

3.以預防代替檢驗,在製程中執行統計製程品管(SPC,Statistical Process Control)。

4.於計數、計量及連續性抽樣作業均可適用(分別有三種抽樣表),不再像以往MIL-STD-105E僅限於計數值抽樣、MIL-STD-414僅限於計量值抽樣與MIL-STD-1235僅限於連續性抽樣(以上標準美軍均已廢止)。

5.把抽樣視為一種浪費的行為,如供應商可提出不同產品之接收計畫,如獲顧客同意後,則可按約定之接收方式辦理驗收。

-STD-1916強調供應商品質系統之建立,以預防為主,而MIL-STD-105E強調顧客之抽樣技術,避免接收不合格件。

此外,以往最常用的MIL-STD-105E抽樣標準,使用之查檢表上就有加嚴、正常及減量等對應查檢表數十個,在運用上並不是很方便,而MIL-STD-1916所使用之表格(含計數、計量及連續性抽樣),就只有4種,在使用之簡便性上,已有大大的改善。

1916抽样实用标准

1916抽样实用标准

MIL-STD-1916抽样标准简介一、前言为强调过程品管与持续不断改良的重要性,美军于1996年推出新版的抽样标准:MIL-STD-1916,用以取代MIL-STD-105E作为美军采购时主要选用的抽样标准。

本标准的目的在鼓励供给商建立品质系统与使用有效的过程控制程序,以取代最终产品的抽样方式,希望供给商远离以AQL(Acceptable Quality Level)为主的抽样计划,而以预防性的品质制度代替它,故本标准之愿景在建立不合格过程改良之制度,而非最终检验品质之水准。

MTL-STD-1916与MIL-STD-105E抽样标准不同之处,主要有以下几点:1、抽样计划以单次抽样〔含加严、正常与减量〕为主,删除双次与屡次抽样,抽样以“0收1退〞〔ZBA Zero Based Acceptance〕当做判定标准,强调不允许不良品之存在。

2、建立持续不断改善之品质系统制度与善用多项品质改善工具。

3、以预防代替检验,在过程中执行统计过程品管〔SPC〕。

4、对计数、计量与连续性抽样作业均可适用〔分别有三种抽样表〕,不再像以往MIL-STD-105E仅限于计数值抽样,MIL-STD-414仅限于计量值抽样与MIL-STD-1235仅限于连续性抽样〔以上标准美军均已废止〕。

5、把抽样视为一种浪费的行为,如供给商可提出不同产品的接收计划,如获顾客同意后,如此可按约定的接收方式办理验收。

6、MIL-STD-1916强调供给商品质系统的建立,以预防为主,而MIL-STD-105E强调顾客的抽样技术,防止接收不合格件。

此外,以往最常用的MIL-STD-105E抽样标准,使用的查检表上就有加严、正常与减量等对应查检表数十个,在运用上并不是很方便,而MIL-STD-1916所使用的表格〔含计数、计量与连续性抽样〕,就只有4个,在使用的简便性上,已有大大的改善。

二、适用X围1、本标准所提供的品质计划与程序,不能减轻供给商满足顾客需求的责任,供给商必须建立品质系统,包括制造程序,品管监控等作业,用以生产符合顾客品质要求的产品。

再以每次10mL蒸馏水连续洗涤三次,继续吸滤以除去痕量水分。

停止吸滤后,仔细取出载有悬浮物的滤膜放在原恒重的称量瓶里,移入烘箱中于103~105℃下烘干一小时后移入干燥器中,使冷却到室温,称其重量。

反复烘干、冷却、称量,直至两次称量的重量差≤0.4mg为止。

注:滤膜上截留过多的悬浮物可能夹带过多的水份,除延长干燥时间外,还可能造成过滤困难,遇此情况,可酌情少取试样。

滤膜上悬浮物过少,则会增大称量误差,影响测定精度,必要时,可增大试样体积。

一般以5~100mg悬浮物量做为量取试样体积的实用范围。

AX46x is used with glass, enamel and antimony pH electrodes and metal Redox sensors, providing measurements with exceptional accuracy and performance.AX400 Series analyzers are available for either wall-/pipe- or panel-mounting and are rated to IP66/NEMA 4X.High Functionality as StandardAll versions are supplied with two, fully isolated current outputs as standard, that can be assigned to the measured parameter,sample temperature or any appropriate calculated variables.Three programmable relay set points are available that can also be assigned as required.Innovative features such as power-saving display and a diagnostic current output option all contribute to a low cost of ownership.Plug-and-Produce Expanded ControlAn advanced function card provides an additional two current outputs and two further alarm relays that can be assigned to either measured values or sample temperature.ABB Plug-and-Produce software automatically reconfigures the analyzer if an option board is added later. No user programming is necessary.A real-time clock and logbook are also included making the full-facility versions extremely powerful and versatile.Significantly Reduced Maintenance CostsThe AX400 analyzers are supplied as standard for 85 to 265V AC operation. There are no inner switches to set.They can also be provided for 24V AC or 12 to 30V DC supply and recognize automatically which of the two supplies is being used. 24V DC operation reduces maintenance costs significantly by negating the need for costly, yearly safety tests to ensure compliance with safety procedures.Energy Saving DisplayThe backlit display has been designed to operate in all types of environments and shows both the measured parameter(s) and,on a separate 16-character display line, diagnostic and computed information.On dual-input analyzers both measured parameters are displayed simultaneously.For conservation of energy, the backlight can be set to switch off automatically after 60s of inactivity.Backlight Can Be Set to Switch Off When InactiveAX400 Termination Chamber Makes Access EasyEasy-Access Installation TerminalsE asy access to the terminations ensures rapid and cost-effective installation. The wall-/pipe-mount version has been designed to ensure that cable connection is simple and convenient. Ingress protection of the electronics section is retained even when the terminal compartment cover is opened.AX400 OutputsSingle and Dual Input Analyzers for pH/Redox (ORP)AX460, AX466 & AX416SS/AX4PH_63Waste Treatment pH & Redox (ORP)pH and Redox (ORP) are essential control parameters when removing toxic chromium ions from waste water in metal-finishing applications. Dual pH and Redox analyzers and integral control simplifies installation and reduces investment costs.Dual Input Measurement for Critical DutiesThe AX400 enables two continuous measurements with simultaneous local display and retransmission. This capability provides an on-line validation of the process measurement.Making two simultaneous measurements and configuring one ofJust-in-Time MaintenanceSingle and Dual Input Analyzers for pH/Redox (ORP)AX460, AX466 & AX416SS/AX4PH_64Reduced Maintenance Through In-line CleaningMany installed pH sensors benefit from regular cleaning. When carried out manually, this can be laborious and costly – so is often ignored. Advanced AX400 pH analyzers make it possible to automate sensor cleaning by using a programmable wash-timer contact to activate a cleaning agent valve or pump.Pulsed water-wash and jet-wash chemical clean actions are standard, user-selectable functions. The frequency and duration of the wash can be tuned to meet the requirements of the application.For chemical cleaning a 60 liter (13 gallon) sensor cleaning station can be supplied (model no. AA0010), complete with delivery pump and low level alarm. Chemical cleaning has proved particularly successful on potable drinking water plants where manganese and iron in the sample can create unacceptably high levels of maintenance. E ffective cleaning reduces cost of ownership.Efficient Auto-cleaning Control for One or Two Sensor SystemsCombined Conductivity and pHThe AX416 version measures conductivity and pH with the same analyzer. The option board provides the capability to retransmit pH, conductivity and both sample temperatures. Five programmable alarms can be assigned to suit the needs of the application, enabling even the most demanding requirements to be met.AX460 Integral P, PI and PID ControlThe single input AX460 analyzers incorporate three-term PID Control, offering three modes of sophisticated control: analog,pulse length (time proportional) and pulse frequency. These aresupplied as standard and can be operated in direct- or reverse-acting mode, dependent upon the application.Auto/Manual and Bumpless TransferAn auto/manual feature is incorporated for rapid manual access to the control functions. The controller facilitates bumpless transfer between manual and auto modes, providing the measured variable is within the proportional band and some integral action time has been programmed.Current Acting ControlSimultaneous Conductivity and pH MeasurementSingle and Dual Input Analyzers for pH/Redox (ORP)AX460, AX466 & AX416SS/AX4PH_65Bi-directional ControlBi-directional ControlAs well as single set point control for both acid and base addition, the AX460 analyzer can be configured with independent controllers.To avoid control overlap, a minimum of 0.5pH difference (or deadband) between the set points is essential. The difference between the set points varies depending upon the application.Control of each set point can be configured independently as either P or PI control in this mode. The setting of proportional band or integral action can also be different for each set point.Time Proportioning Control (Pulse Length)With time proportioning control, the AX460 analyzer’s control signal output is in pulses, the duration of which changes in proportion to the system error. The pulses are delivered by varying the length of time that the alarm/control contact is activated.Time Proportioning Control is used generally to control dosing by low-cost solenoid valves or metering pumps and is also known as pulse-length proportional or Mark Space control.Pulse-frequency Proportional ControlPower Failure RecoveryIn the event of a power failure the user can configure the control mode to be Auto, Manual or Last. This optimizes control conditions on power-up to ensure rapid recovery of process control.Time Proportioning ControlPulse-frequency Proportional ControlImpulse pumps dosing chemical reagents are controlled easily by the AX460 analyzer’s pulse-frequency proportional control output. In this case, the pulse length of the alarm/control contact is fixed and the frequency of the delivered pulses increases in proportion to the system error, as set by the proportional band.Diaphragm metering pumps must have a remote pulse input capability in order to utilize this function.Pulse-frequency control in the AX460 analyzer operates by pulsing a relay on for 300ms and off for a period of time determined by the pulse frequency. The pulse frequency (PFr) is adjustable between 1 and 120 pulses per minute. The greater the difference between the measured variable and the set point the greater the pulse frequency.ExampleIf the pulse frequency is set at 120 pulses per minute and the percentage output is 100% then the pulse rate is 2 pulses per second.

4、钻孔孔径、孔深钻孔开孔孔径ф87mm,深8米,终孔孔径ф65mm,设计孔深见附图。

5、封孔工艺封孔方式为1:2水泥沙浆机械封孔,选用聚氯乙稀抗静电塑料管,堵孔管长度为8米,注浆管长度为0.5米。

封孔时,先将堵孔管和注浆管固定,然后将1:2水泥沙浆通过重庆淑维机电设备制造厂生产的BFK-10/1.2型注浆机(压力1.2mpa,流量10c/min,功率4KW,重量165kg)和注浆管注入钻孔,直到堵孔管返为止,24小时后开始接抽。

6、钻孔参数(见附表)7、附图(1) 4606穿层抽采钻孔布置平面图(2)机械封孔示意图(3)4606穿层抽采钻孔终孔平面图(4)4606穿层抽采钻剖面图四、施工安全防护措施1、在施钻过程中,若出现卡钻、吸钻、抱钻、喷孔、瓦斯忽大忽小、瓦斯持续上升、响煤炮、软分层增厚、地质构造,矿压显现等明显动力现象等突出预兆时,必须停止打钻,电话向调度室汇报采取措施进行处理。

2、每孔开孔前,必须提前检查并完善通风系统、通风设施、监控系统、并保证每周不少于一次的探头调校、通风系统及设施检查和电气设备防爆性能检查。

3、打孔点及回风侧分别设置瓦斯传感器,报警浓度均为1%;回风侧5m内挂设便携式报警仪,严禁瓦斯超限进行打孔作业。

4、打孔时现场不能超过3人,打孔回风侧严禁有人员作业和检查。

施钻人员必须随身携带隔离式自救器。

5、牌板管理 :打孔现场图板及现场标志设在打孔点后侧20m处,由防突员和瓦检员负责管理。

6、按《煤矿安全规程》规定,打孔区域必须支护可靠,严禁空顶作业。

7、施钻前,由防突员及打孔负责人负责检查撤退路线是否畅通,只有当所有设施、设备均符合要求时,方可开钻打孔。

8、钻孔由当班技安员验收,打完一个孔必须停止作业,通知验孔人员进行验孔并按规定作好记录。

9、打完一个孔验收后必须按规定进行封孔,并与主瓦斯管接通,只有在验孔、封孔结束后方能开钻第二个孔。

10、瓦斯避灾路线 :打孔点4606大巷向东→+686m井口平硐→井外。

11、若发现打孔点片帮、顶板垮塌、瓦斯涌出异常,必须立即停止作业、汇报。

12、施钻当班必须先检查撤退路线是否畅通、安全设施是否完好,若出现异常,必须先整改隐患,否则严禁施工钻孔(当班负责人负责,防突员监督 )。

13、必须明确一名人员管理压风自救系统、隔离式自救器等防突设施,并按要求进行安装、维护和保养,由施钻班长负责。

五、4606穿层抽采安全措施1.抽出的CH4采用民用和排空,应按规定搞好排空瓦斯管的避雷设施。

2.管道安设前排尽管内的积水和杂物,转弯处设弯头,变坡起伏变化的最低点应设放水器。

3.在敷设倾斜管路时应采用管长将管子固定在支架上管卡间距一般6m~7m,采用法兰盘联接时,接头处应该按好垫圈,严防漏气,胶皮垫的厚度不小于5mm并用螺丝加金属垫紧固。

4.抽放管路系统应按规定在抽放泵泵房的进气端安设测CH4浓度。

抽放负压,测定CH4流量的管嘴,不用时用堵头封堵严密,严禁漏气。

5.抽放管路系统中附属设备如阀门,放水器,放空管与避雷器布置合理便于操作检修维护。

6.抽放泵房用不燃性材料交护,所有电器设备必须防爆,严禁失爆,司机必须经专业培训合格者持证上岗,通风照明良好,〈防燃灯具〉有直通矿调度的直通专用电话,应安设甲烷传感器,报警浓度0.5%断电浓度1%。
