in appearance (making it difficult to obtain strictly identical repeat samples) or in aftertaste (making direct comparison difficult)

The risk of failing to contradict an incorrectly declared quality level which is related to the LQR is no more than 10 %

Restrained joint systems for ductile iron pipelines. Design rules and type testing Ingestion-build-86103 Test code for the determination1 Scope This document specifies the design rules and type testing for restrained joint systems to be used on ductile iron pipelines complying with ISO 2531 and ISO 7186, in order to determine their mechanical properties and leaktightness.
