Fuel cell technologies - Test methods. Single cell performance tests for polymer electrolyte fuel cells (PEFC)1 Scope This document covers cell assemblies, test station setup, measuring instruments and measuring methods, performance test methods, and test reports for PEFCsingle cells. This document is used for evaluating: a) the performance of membrane electrode assemblies (MEAs) for PEFCs in a single cell configuration; b) materials or structures of PEFCs in a single cell configuration; or, c) the influence of impurities in fuel and or in air on the fuel

See the full range of biometrics standards in the BS ISO/IEC 19794 series

Using BS EN IEC 62149‑10 you understand the radio-over-fibre transceivers performance requirements together with a series of tests and measurements with clearly defined conditions

ISO 11126-5 specifies requirements for nickel slag abrasives

NOTE This method could also be used for the determination of other monomers

and transportation systems that are characterized according to their magnitude
