Aug 30, 2026

Uploaded by Eden

This ESCC Basic Specification defines the requirements for Process Capability Approval (PCA) for suppliers performing manufacturing, assembly, and test operations for electrical, electronic, or electromechanical (EEE) components intended for space applications. It clarifies the scope, applicable documents, key definitions, and the process capability domain. It establishes supplier and domain evaluation, PCA approval testing, testing documentation, approval validity, and procedures for extension, re-certification, suspension, and non-conformance handling, including supporting forms and flow charts.

FAQs

What is the purpose of ESCC 25600 Issue 2?

It defines the requirements for Process Capability Approval (PCA) of suppliers involved in manufacturing, assembly, and test operations for space application EEE components.

Does PCA approval qualify the supplier’s products under ESCC Qualification?

No. PCA certification to a supplier does not include or enable ESCC Qualification of products; product qualification may be achieved through other specified ESCC documents.

What are the main phases of a PCA programme?

In general, the programme consists of four phases: defining the process capability domain and boundaries, evaluating the supplier, evaluating the process capability domain, and performing PCA testing.
