3.1 critical characteristic
kind of characteristic whose fault would cause failure of the whole system or major subsystem to perform a required mission or create serious harm to the safety of humans
3.2 end product
product in the assembled and completed state at which acceptance will take place
3.3 inspection unit
unit on which characteristic inspection is performed
3.4 major characteristic
kind of characteristic whose fault would cause the end product fails to perform a required mission
Note 1 to entry: It would not cause failure of the whole system or major subsystems which perform a required mission.
3.5 minor characteristic
kind of characteristic significant to product quality, but whose fault could not affect realization of mission performance of product
4 General requirements
4.1 In support of product quality and mission functions, management of product characteristic shall be implemented. As part of management process of product characteristics, the suppliers shall identify and classify product characteristics which shall conform to the requirements submitted by their customer, and implement control measures according to classification in order to highlight those areas of the product to which specific attention, control or inspections shall be applied.
4.2 The suppliers shall especially identify critical and major product characteristics during design phase, focus on their control during the process generating critical and major characteristics, and inspect their conformance with the design requirements.
4.3 According to the severity of the consequences caused by failure and non-conformance with the design requirements, product characteristics are classified into critical characteristics, major characteristics and minor characteristics. The suppliers shall strengthen control of critical and major characteristics with proper measures during the production and inspection process.
