ÖNORM EN 1232

This European Standard specifies performance requirements for battery powered pumps used for personal sampiing of chemical agents in the workplace atrnosphere. It also specifies the methods of laboratory type testing for determination of the performance characteristics under prescribed laboratory conditions. This European Standard is applicable to purnps whose nominal volumetric flow rate is within the range 5 mflrnin to 5 Ilmin and which are used together with sampling devices typical for such flow rates for the sampling of gases, vapours, dusts, fumes, mists and fibres. This European Standard is not applicable to pumps with a flow rate outside this range or for pumps which are used with sampling devices whose flow resistance significantly exceeds the values for back pressure listed in 4.6 and 4.7. This European Standard is equally applicable to pumps with a constant flow rate and to stroke pumps with a constant stroke volume. Sampling purnps are classified according to their intended use: - Type P: pumps for personal sampling of particulate matter; - Type G: pumps for personal sampling of gases and vapours.
