Description / Abstract:
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 program, 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 produceridentified 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.
