Early Production Containment
GP-12

NOTE: GP-12 'Early Production Containment" (GM-1920) has been incorporated into the General Motors Specific Section of the "Production Pan Approval Process" procedure. The February, 1995 Revision to PPAP includes this change.
注： 初期生产控制-GP12 (GM-1920) 已被合并到《生产件批准程序》中《通用汽车规范》一章。1995年2
月对PPAP的修改包含此更改内容。

1.0 SCOPE. This procedure applies to all suppliers required to use the Production Part Approval Process (PPAP). It is to be used for all pre-production and production requirements that require the Production Part Approval Process. GP-12 should not be used for carry over quality concerns: they should be addressed using the Controlled Shipping Procedure.
1.0 范 围
此程序适用于所有要求进行“生产件审批”程序(PPAP)的供应商。它适用于要求生产件批准程序的试生产和正式生产阶段。 GP-12不应用于质量问题的解决，对这些问题应使用发货控制程序。

2.0 DEFINITION AND PURPOSE The purpose of GP- 12 is to document the supplier's efforts to gain control of its processes during start-up and acceleration so that any quality issues that may arise are quickly identified and corrected at the supplier's location and not at the GM customer's manufacturing location. GP-12 Early Production Containment requires a Pre-Launch Control Plan a significant enhancement to the supplier's production control plan which will raise the confidence level to ensure that all products shipped initially will meet GM’s expectations. The pre-launch control plan will also serve to validate the production control plan. The Pre-Launch Control Plan should take into consideration all known critical conditions of the part as well as potential areas of concern identified during the Production Part Approval Process. GP-12 Early Production Containment serves to proceduralize the Pre-Launch Control Plan referred to in section 3.7 of the Chrysler, Ford, GM Advanced Product Quality Planning and Control Plan Reference Manual.

2.0 定 义 和 目 的
GP-12的目的是记录供应商在生产初期和生产加速过程中，为控制其工艺所做的工作，从而使任何可能出现的质量问题都可以在供应商现场被及时发现并解决 ，而不是在通用汽车顾客的生产现场。初期生产控制 (GP-12) 要求有一个投产前控制计划，是供应商生产控制计划的重要保证，它可提高可信度以确保所有初始装运的零件满足通用汽车的要求。投产前控制计划还可用于验证其生产控制计划。投产前控制计划应将零件所有的已知重要情况和在生产件审批 (PPAP)中发现所涉及的潜在问题同样考虑在内。GP-12初期生产控制是做为《APQP和控制计划参考手册》中3.7章所提及的“投产前控制计划”的程序。

Note: This procedure does not provide authorization to ship nor is it a shipping schedule

3.0 SUPPLIER RESPONSIBILITY
供 应 商 职 责
The Supplier must do the following:
供 应 商必 须 开 展 以 下 工 作 ：
A. Establish a containment process that contains the following elements:
制 定一 个 控 制 程 序 ， 包 括 以 下 要 素 ：
1. Identification of the person responsible for the containment process.
控 制 程 序 负责 人 的 确 定
2. Development of a Pre-Launch Control Plan consisting of additional controls, inspection audits and testing to identify non-conformance’s during the production process. Depending on the dominant factor if the introduction process (set-up, machinery. fixture. tooling. operator. material/components, preventative maintenance, climate) additional controls could include:
制定投产前控制计划，包括附加控制、检查和试验，从而可以在生产过程中发现不合格品。取决于主要因素，是否生产过程 (试模，加工，夹具，工装，操作工，原料/零部件，预防性维修，环境)中应包括以下几点：
• Increased frequency/sample size of receiving. process. and or shipping inspections
在入厂控制，生产工艺和发货检验中增加检验频次/抽样数量
• Mandated sub-supplier containment and or sub-supplier support/audits
强制进行的分供商控制和分供商支持/检验
• Addition of inspection/control items
附 加 的 检 验 / 控 制 项 目
• Increased verification of label accuracy
增加标识准确性的检查
• Enhancement of process controls. such as error proofing
加 强 工 艺 控 制 ， 例 如 防 错
• Error proofing validation through introduction of known defects
通过已知缺陷来验证缺陷
• Increased involvement and visibility of top management
高 级 管 理 层 的 参 与 和 管理 的 增 加
3. Prompt implementation of containment/correction when non-conformances are discovered
当 发 现 不 合 格 时 ， 及 时 采 取 遏 制 措 施 / 改 正 措 施
4. Identification of the measurement equipment and data collection devices/activities to be used
where applicable 验证测量设备和数据收集装置/方法是否用于其所在的工位

B. Document the Pre-Launch Control Plan, including functional testing and error proofing, using the Control Plan format referenced in the Advanced Product Quality Planning and Control Plan Reference Manual.The development and documentation of the Pre-Launch Control Plan are expected to occur during the Advanced Product Quality' Planning process. The Pre-Launch Control Plan is not a substitute for the Production Control Plan but is over and above the Production Control Plan and is used to validate it.
参照《先期产品质量策划和参考手册》中的控制计划格式将投产前控制计划形成文件，其中包括功能测试和防错。在产品质量先期 策划过程中应制定和编写投产前控制计划。投产前控制计划不能代替生产控制计划，它包括生产控制计划，并可用于验证生产控制计划。

C. Utilize the Early Production Containment Plan for all pre-production requirements (e.g.. pilot, lead unit build) and for the production ship quantity or duration specified by the procuring division or until the Production Control Plan is validated, whichever occurs later. Typically, the specified production quantity or duration is intended to reflect the customer's acceleration plan to full production rate. If not specified by the procuring division, the production ship quantity is a minimum of 1200 pieces for each GM customer plant, in addition to any pre-production quantities required.
初期生产控制计划适用于所有试生产阶段的要求 (如试生产，样车组装)，并且适用于按照采购部门指定的数量或时间期限内发运的生产件，或者直到生产控制计划得到验证，以后者为准。通常情况下，指定的生产数量或期限应反映出顾客的生产加速计划来达到最大生产负荷。如果采购没有指定要求，生产件发运数量应最少达到1200件，还不包括任何试生产数量。

D To indicate compliance with the GP-12 requirements, attach to each shipping label a green dot signed by a designated
senior management representative, typically the highest level manager at the production facility. (The green dot should
have a diameter of 1.25 to 2 inches.) 为表明达到并满足GP-12要求，在每个发运标签要贴有一个指定的管理层代表签字的绿色圆点标识 ( 绿色圆点规格为直径1.25英寸~2英寸)

4.0 EXIT CRITERIA Supplier will be eligible to exit Early Production Containment on its own accord after meeting the criterion listed below. If the supplier is unable to meet the exit criteria or the supplier’s GP-I2 plan continues to identify non-conformances the supplier is expected to continue the necessary containment measures to insulate the Customer Plant up to the time when the quality concerns have been resolved to the satisfaction of both the Supplier and the Customer and the Supplier’s Production Control Plan is validated.
4.0退 出 标 准
如符合以下标准，供应商就可以完成并退出先期生产控制程序。如供应商不能满足退出标准或供应商的GP-12计划不能有效防止不合格品，供应商要继续采取必要的遏制措施，并防止不合格品流入顾客生产车间，直到质量问题被解决，达到供应商和顾客都满意并且供应商的生产控制计划得到最终验证。

A. Ship the number of pieces or for the duration specified by the procuring division with no discrepancies or customer plant PR/R’s and supplier can self exit from the Early Production Containment Process
在 采 购 部门 规 定 的 装运 数量 或 期限内 没 有不合格品 或顾 客 工 厂没有PR&R发生，供应商可以自动退出先期生 产控制程序。
B. If supplier does not meet self exit criteria then to exit GP-12 all PR/R’s must be closed by the Customer Plant
如果供应商不满足自动退出标准，供应商在所有的PR/R得到顾客工厂并闭之后才能退出GP-12。
C. In the event the self exit criteria has been met but the GP-12 plan continues to identify non-conformances, the GP-I 2 plan must be kept in place until process controls and capabilities have proven effective and the Production Control Plan is validated. 如果已满足自动退出的标准但GP-12仍不能有效控制不合格品，那么必须保留GP-12计划，直至过程控制和能力被证实是行之有效的，并且生产控制计划得到验证。
