BS EN 13936 is an International Standard that focuses on workplace exposure. It gives the best procedures and test methods for measuring a chemical agent present as a mixture of airborne particles and vapour.
BS EN 13936 specifies performance requirements and test methods for the evaluation of procedures for measuring a chemical agent present as a mixture of airborne particles and vapour in the workplace air.
BS EN 13936 establishes general principles to enable developers and users of mixed-phase samplers and methods to adopt a consistent approach to method validation and provides a framework for the assessment of method performance.
BS EN 13936 on testing the presence of the chemical agent is useful for:
Representative assessment of occupational exposure to airborne microbial organisms or compounds is challenging. However, because of potential health consequences following exposure, it is important to be able to evaluate and control exposure. The sampling equipment used can introduce its critical limitations, such as the assessment of the health-related aerosol fractions.
BS EN 13936 specifies general requirements for performing the procedures that give the measurement of the concentration of chemical agents in workplace atmospheres. These performance criteria include maximum values of expanded uncertainty achievable under prescribed laboratory conditions for the methods to be used. Chemical agents in workplace air are often present in both gaseous and non-gaseous phases at the same time and therefore validated methods are required that can measure the combined concentration of the chemical agent in both phases.
By using BS EN 13936, you can measure the mass concentration of the inhalable fraction of hazardous chemical agents, regardless of whether they are present as airborne particles or vapour.
