42、mp. When workplace air containing a particular chemical agent is drawn through the detector tube, a colour change takes place corresponding to the concentration.Such short-term detector tube measurement systems have many applications. This International Standard refers to detector tubes used for wor
43、kplace air monitoring. These detector tubes can be used for measurement tasks such as follows: determination of the presence or absence of an analyte; finding the approximate range of concentration; determination of the efficiency of control measurements; determination of emission sources and emissi
44、on changes in time; determination of compliance with ceiling or short-term limit values, as long as the device covers the reference time period and the precision requirements for the measurement.To cover the possible range of concentration that can be encountered in the workplace, a combination of t
45、wo or more measurements using detector tubes with restricted but complementary and overlapping measuring ranges can also be used.This International Standard will enable the manufacturers, test houses, certification bodies, and the users to adopt a consistent approach to the assessment of performance
46、 of short-term detector tube measurement systems.EN ISO 17621:2015 (E) 6DIN EN ISO 17621:2015-12 1 ScopeThis International Standard specifies requirements and test methods under prescribed laboratory conditions for length-of-stain detector tubes and their associated pump (detector tube measurement s
