Using the BS EN ISO 9004:2000 criteria

— common assessment criteria and related examples of water quality indicators

12 on the method of declaring parameters for lung ventilators is useful for:

— all major overhauls of the above-mentioned vehicles if they involve redesigning or extensive alteration to the brake system of the vehicle concerned

provided they are clearly marked with PAS 44:2002 and differentiated from PAS 44:2009 eartags both at point of sale and on the Ear Tag Allocation System (ETAS)

Turbines and turbine sets. Measurement of emitted airborne noise. Engineering/survey method Ingestion-build-133579 Using the BS EN ISO1 Scope This document specifies methods for measuring the noise emission of a turbine or turbine set under steady state operating conditions. It specifies methods for measuring the sound pressure levels on a measurement surface enveloping a source, and for calculating the sound power level produced by the source. It gives requirements for the test environment and instrumentation, as well as techniques for obtaining the surface sound pressure level
