National laws and regulations based on European Directives require the assessment of the potential exposure of a worker to chemical agents in workplace atmospheres. One way of assessing such exposure is to measure the concentration of a chemical agent in the air in the worker's breathing zone. The procedures used for such measurements should give reliable and valid results, so that when compared with set occupational exposure limit values, a correct decision can be made, for instance, as to whether the exposure level is acceptable or control measures need to be applied. Because of their importance in the process of exposure assessment, it is required that the measurement procedures fulfil some general requirements which are given in this standard. These requirements apply to all measuring procedures, irrespective of the physical form of the chemical agent (gas, vapour, airborne particles), the sampling method and the analytical method used. The standard is a revision of the previous 2006 edition taking into account the new editions of DIN EN 838, DIN EN 1076 and DIN EN 13890 published in 2010. The standard has been prepared by CEN/TC 137 "Assessment of workplace exposure to chemical and biological agents" (secretariat: DIN). The responsible German standardization committee is NA 095-03-01 AA "Messstrategien und Anforderungen an Messverfahren" ("Measurement strategies and requirements for test methods") of NASG.
