Workplace air. Guidance for the measurement of respirable crystalline silica1 Scope This International Standard gives guidelines for the quality assurance of measurements of respirable crystalline silica in air using direct on filter or indirect X ray diffraction and infrared analysis methods. The scope of this International Standard includes the following crystalline silica polymorphs: quartz, cristobalite, and tridymite. These guidelines are also relevant to the analysis of filters obtained from dustiness measurements in

BS IEC 60860 is primarily intended to apply to equipment design and

Multi-sensor fire detectors using carbon monoxide and heat sensors having special characteristics suitable for the detection of specific fire risks are not covered by this European Standard

operating from a supply or battery of less than 1 000 V AC or 1 500 V DC or from the circuit being measured

This curve can then be converted into a stress versus strain curve

where relevant (see Clause 6)

BS EN 13063-2 also provides you with a sequential testing method that helps you to verify that these requirements are met and the chimney operates under wet conditions
