4. QUALITY ASSURANCE PROVISIONS
4.1. Q ualification T esting
A. Sam ple Selection
Sam ples shall be prepared in accordance with applicable Instruction Sheets and shall be selected
at random from current production. All test groups shall each consist of 10 cluster block housings
or a s s emb lies w ith a minimu m of 1 a s se mb ly pe r w ire s ize (e x ce p t w he re the w ire s ize is n o t a
factor).
B. Test Sequence
Q ualification inspection shall be verified by testing sam ples as specified in Figure 2.
4.2. Requalification Testing
If changes significantly affecting form , fit or function are m ade to the product or m anufacturing process,
product assurance shall coordinate requalification testing, consisting of all or part of the original testing
sequence as determ ined by developm ent/product, quality and reliability engineering.
4.3. Acceptance
Acceptance is based on verification that the product meets the requirements of Figure 1. Failures
attributed to equipment, test setup or operator deficiencies shall not disqualify the product. If product
