1) for ripe component product, external space flight mechanism is by establishing PPL (the preferred catalogue of component), QPL (identifications
Qualified catalogue) etc. mode carry out component condition managing.
NASA is to ensure that stablizing for aerospace component is supplied, and establishes preferred catalogue NPSL (the NASA Parts of component
Select List), it is the supply baseline that government establishes, and NASA is as a kind of resource that must control of country, from should
Controlled comprehensively to technical support with, research and development.
NPSL is also a vital document in NASA component product specification systems, and NPSL has 2000 multipages, content bag
Include component model specification, supplier, basic mechanical design feature, foundation specification and predetermined application level etc..NPSL by
NASA component guarantee groups (NEPAG) manage and control, selection be included in NPSL component have to by the quality of NEPAG with
Reliability examines evaluation.Meanwhile NASA has also set up two core supplier inventories (CSL) as boat on the basis of NPSL
The fixed point guarantee of its component, CSL include core active device inventory.NASA is selected, in evaluation and approval in component, mainly
Selected for manufacturer and component, prioritizing selection source, capability of resistance to radiation and drop volume etc. propose requirement.
ESCC is selected and buying component will be according to component applicable cases, and in EPPL, (European component is preferred as far as possible
Catalogue), selection in QPL (qualified products list (QPL)), to be purchased in buying according to controlled product specification requirement, and to the greatest extent may be used
Competitive European component can preferentially be purchased.The selection and buying general requirements of component are made in standard ECSS-Q-60B
Specific provision.By the foundation and management of catalogue, guiding user's use can cover the component of its demand and limited quantity
Type, to avoid repeating, realizes that kind is compressed, and reduces cost by the increase of dosage, improves the validity of buying.
ESA confirms that file (PID) implements condition managing to component by establishing process.PID is to be used as expression using file
Mode, confirming by appraisal organization, prerequisite specifically to formation product overall process of aerospace component factory
Seek the summation of file.
Explicitly pointed out in ESCC22700：The purpose of PID consistent with ESCC systems is built for the identification or accreditation of electronic component
