and measuring of flammable gases or vapours in ambient air by measuring the spectral absorption by the gases or vapours over extended optical paths

The measurement methods fall into three categories:

BS EN 2997-007 specifies the characteristics of hermetic receptacles with round flange attached by welding or brazing in the family of circular electrical connectors coupled by a threaded ring

Safety requirements and testing for portable, hand-held, powered brush-cutters and grass-trimmers - Machines fitted with an integral combustion engine Ingestion-build-189776 and measuring of flammable gases1 Scope This part of ISO 11806 gives safety requirements and measures for their verification for the design and construction of portable hand held, powered brush cutters and grass trimmers (hereafter called machines) having an integral combustion engine as their power unit and mechanical power transmission between the power source and the cutting attachment. Methods for the elimination or reduction of hazards arising from the use of these machines and
