- This standard is primarily intended to apply to new parts and products, but can also be applied to parts currently in production. The standard shall be applicable to all production processes that influence the variation of KCs, as well as maintenance processes in which KCs are identified. It applies to assemblies and all levels of parts within an assembly, down to the basic materials including castings and forgings, and to organizations that are responsible for producing the design characteristics of the product. It does not apply to lab-scale, pilot, or pre-production processes. However, particular management of some KCs might be required using other methods than those described in the standard, during these phases of a programme, when required by the customer or deemed appropriate by the organization (e.g., Engineering department requirement). The variation control process begins with product definition, typically an engineering drawing or specification which identifies KCs, and leads to a variation management program for those KCs. This process may also be used for producer-identified KCs. Producers and their subcontractors shall be responsible for flow down of the requirements of the applicable revision of this standard to subcontractors, who produce design characteristics, and for ensuring that KCs conform to customer requirements. This standard is designed to drive the improvement of manufacturing and maintenance processes through adequate planning and effective management of KC variation. The KC focus is intended to improve confidence for part features whose variation has a significant influence on to end-product form, fit, performance, service life, and producibility. The following conventions are used in this standard: - The words "shall", "will", or "must" indicate mandatory requirements. - The word "should" indicates a requirement with some flexibility allowed in compliance methodology. - Producers choosing other methods to satisfy a "should" shall be able to show that their approach meets the intent of the requirements of this standard. - Words "typical", "example", "for reference", "may", or "e.g." indicate suggestions given for guidance only. - "NOTES" are used for additional clarification. - Words or phrases with specific meaning pertaining to this document are defined in Clause 3, Terms and Definitions.
| 术语 | 描述 |
|---|---|
| 关键项 Critical Item (CI) | those items (e.g., functions, parts, software, characteristics, processes) having significant effect on the product realization and use of the product; including safety, performance, form, fit, function, producibility, service life, etc.; that require specific actions to ensure they are adequately managed. Examples include safety CIs, fracture CIs, mission CIs, KCs, and maintenance tasks critical for safety |
| 客户 customer | the organization which identifies CIs and/or provides part or system KCs via engineering drawings, specifications, or purchase order/contract requirements. For example, a customer may be an internal engineering department for a company which has design authority, in addition to the external customer who specifies system KCs |
| 关键特性 Key Characteristic (KC) | an attribute or feature whose variation has a significant influence on product fit, performance, service life, or producibility; that requires specific action for the purpose of controlling variation (reference 9100 and 9110) |
| 关键特性所有者 Key Characteristic (KC) owner | the person or function that defines the KCs and recognizes the reasons for the selection of the KCs. Typically, these responsibilities are held by internal/external customer design, quality, manufacturing, or maintenance engineering and are identified by a cross-functional team |
| 特殊原因 Special cause | variation caused by a source that is not part of the constant system or process |
