The following specific joint types are covered by BS EN 10311: butt welded joints

It does not apply to set screws and similar threaded fasteners not under tensile stresses (see ISO 898-5)

Air quality. Determination of time-averaged mass emissions and emission factors. General approach Ingestion-build-44680 will define the success ofBS EN ISO 11771: 2010 Air quality Determination of time averaged mass emissions and emission factors General approach (ISO 11771: 2010) BS EN ISO 11771 is an International Standard which describes the measurement procedures necessary to determine the mass emission of substances from stationary sources. Empirically generated data are necessary to determine the uncertainty that can be associated with a stated result and to enable the verification of
