Non-destructive testing. Leak testing. Calibration of reference leaks for gases1 Scope This document specifies the calibration of those leaks that are used for the adjustment of leak detectors for the determination of leakage rate in everyday use. One type of calibration method is a comparison with a reference leak. In this way, the leaks used for routine use become traceable to a primary standard. In other calibration methods, the value of vapour pressure was measured directly or calculated over a known volume. The comparison

Why should you use BS EN 50436-4

and cost-effective manner

BS EN 15342 does not cover the characterization of plastics wastes

This range includes the liquefied natural gases (LNGs) and liquid petroleum gases (LPGs)

BS IEC 60748-23-3 provide the hybrid manufacturer and the National Supervising Inspectorate (NSI) with ongoing information on process control demonstrating compliance with IEC 60748-23-1
