This standard specifies a manual gravimetric standard reference method (SRM) for the determination of the dust load (dust content) and the dust mass flow of a dust/gas mixture flowing through defined cross-sections (e.g. stacks, pipelines or ducts). Such measurement objectives mainly arise, if dust emissions have to be determined, e.g. in case of a check of compliance with limit or guarantee values, calibration of automated dust emission measuring systems, performance measurements at dust precipitators, and during check or optimization of process parameters. This standard can be applied at different dust contents according to the following application ranges, and in case of measurements in waste gases up to water-vapour saturation without water droplets as well as for measurements in waste gases with water droplets. It is applicable in the following application ranges: application range A - expected dust mass concentration up to 50 mg/m³; application range B - expected dust mass concentration between 50 mg/m³ and 150 mg/m³; application range C: expected dust mass concentration between 150 mg/m³ and 2 g/m³. The sampling time of a single measurement is usually 30 min. This standard is applicable to measurements at stationary sources. For the application range A, the technical requirements of this standard are identical to those of DIN EN 13284-1. In this case, they fulfill the normative requirements of DIN EN 13284-1. For plants covered by European regulations (e.g. Directive 2010/75/EU), the dust measurement according to DIN EN 13284-1 is strictly required. This applies to plants the erection and operation of which is regulated by the 13th or 17th ordinance on the implementation of the German Federal Immission Control Act (BImSchG). If the dust measurement is carried out for these plants in accordance with application range A of this standard, the equivalence with DIN EN 13284-1 shall be indicated in the measurement report. This standard is addressed to test laboratories performing measurements of dust emissions, to manufacturers of corresponding measuring systems, to competent authorities and to research facilities active in this field.
