VDI 4221 Blatt 2:2015-09

This standard specifies requirements on the design of interlaboratory testing schemes and the performance and evaluation of interlaboratory tests for emission measurement methods under laboratory conditions. This standard applies to interlaboratory testing schemes for control of test laboratories with respect to the quality of the use of measurement methods for the determination of stationary source emissions. These testing schemes include interlaboratory tests for particulate components and chemical compounds adsorbed to particulates as well as to gaseous inorganic and organic chemical compounds. This standard may be applied in conjunction with VDI 4221 Part 1 only. This standard applies to providers of interlaboratory tests, to accreditation bodies, to testing laboratories and competent authorities in the field of immission control.
