type testing

tt

testing performed to prove that the compound (3.13) , component (3.21) , product (3.16) , joint (3.22) or assembly (3.23) is capable of conforming to the requirements given in the relevant standard

Note 1 to entry: The type test results remain valid until there is a change in the compound (3.13) or product (3.16) or assembly (3.23) provided that the process verification tests are done regularly.

3.7

batch release test

BRT

test performed by or on behalf of the manufacturer on a batch of compound (3.13) , components (3.21) or products (3.16) , which has to be satisfactorily completed before the batch can be released

3.8

process verification test

PVT

test performed by or on behalf of the product manufacturer on compounds (3.13) , components (3.21) , products (3.16) or joints (3.22) at specific intervals to confirm that the process continues to be capable of producing components (3.21) and products (3.16) which conform to the requirements given in the relevant standard
