Why should you use ISO 15874‑7- Plastics piping systems?
Conformity assessment involves a set of processes that show your product, service or system meets the requirements of a standard.
ISO 15874‑7 is intended to provide you with general guidance on the concept of testing and the organization of those tests used for the assessment of conformity. For each type of test, i.e., type testing (TT), batch release test (BRT), process verification test (PVT), and audit test (AT), ISO 15874‑7 details the applicable characteristics to be assessed as well as the frequency and sampling of testing.
As a user of ISO 15874‑7, you are provided with a typical scheme for the assessment of conformity of materials, compounds, pipes, fittings, valves, joints or assemblies by product manufacturers. In this manner, you can ensure that the products consistently meet and exceed quality expectations.
