Heavy duty engines. Measurement of gaseous emissions from raw exhaust gas and of particulate emissions using partial flow dilution systems under transient test conditions1 Scope This International Standard specifies methods for the measurement and evaluation of gaseous and particulate exhaust emissions from heavy duty engines under transient conditions on a test bed. The procedures it defines can be applied to any transient test cycle that does not require extreme system response times; it can therefore be used as an option to the regulated measurement equipment of certification test cycles usually CVS type systems

Quality control and regulatory authorities

BS EN 1737 on prefabricated concrete out-of-plane joint strength is useful for:

NOTE 3 Some of the guidance of this part of ISO 20282 could be applicable to other types of systems in everyday use

These two adaptations differ mainly with regard to the reporting and the presentation of results

Why should you use BS 9522 N0001 - Detail specification for connectors

ISO 1302:1992

Other minor changes in the light of experience of use

BS EN ISO 11970 defines the conditions for the execution of welding procedure approval tests and the limits of validity of an approved welding procedure for all practical welding operations within the range of essential variables
