이 표준은 작업장에 존재하는 염화수소(HCl) 가스와 염산 미스트, 브롬화수소(HBr) 증기, 브롬화수소산 미스트, 질산(HNO3) 증기와 미스트의 시간-가중 평균 질량 농도를 알칼리 함침 석영 섬유 필터(alkali-impregnated quartz fibre filter) 채취와 이온 크로마그래피 분석을 통해 측정하는 방법에 대해규정한다.KS I ISO 7708에 정의된 대로, 미스트 채취 시, 이 방법은 사람이 흡입하는 공기 중 입자 채취와 고정(지역) 시료 채취에 적용된다.이 분석법은 시료당 0.01 mg∼2.5 mg 질량의 HCl, HBr, HNO3의 측정에 적용된다.측정 절차에서 공기 중 HCl, HBr, HNO3의 농도 범위는 사용자가 선택한 채취 방법에 따른다. 공기시료가 240 L라면, HCl, HBr, HNO3의 측정 범위는 약 0.04 mg/m3∼10 mg/m3가 된다.이 절차는 산과 해당 염기를 구분한다. 공기 중에 두 가지가 모두 존재하는 경우, 전필터(pre-filter)로염기 입자를 걸러낸다. 필요에 따라 전필터에 걸러지는 입자 및/또는 채취 장치 벽에 침전되는 입자를 모두 분석할 수 있다.산은 전필터에 함께 채취되는 입자와 반응하여 산 농도 측정을 방해할 수 있다.

This part of ISO 17734 gives general guidance for the sampling and analysis of airborne isocyanates in workplace air. When amines and aminoisocyanates are suspected to be emitted (e.g. from thermal degradation of PUR), it is recommended that, in addition to isocyanates, the amines and aminoisocyanates in the air are determined, using DBA and ethyl chloroformate as reagents (see ISO 17734-2).

This part of ISO 17734 gives general guidance for the sampling and analysis of airborne amines and aminoisocyanates in workplace air. It is strongly recommended that the determination of amines and aminoisocyanates is made together with the determination of isocyanates in air, using DBA as a reagent (see ISO 17734-1).

This International Standard specifies performance requirements for battery powered pumps used for personal sampling of chemical and biological agents in workplace air. It also specifies test methods in order to determine the performance characteristics of such pumps under prescribed laboratory conditions. This International Standard is applicable to battery powered pumps having a nominal volume flow rate above 10 ml ⋅ min, as used with combinations of sampler and collection substrate for sampling of gases, vapours, dusts, fumes, mists and fibres. This International Standard is primarily intended for flow-controlled pumps.

This International Standard gives general guidance for the sampling and analysis of airborne toluene diisocyanate (TDI) in workplace atmospheres. The procedure specified in this International Standard is especially suitable for short (15 min) and long-term (4 h) sampling and analysis of 2,4- and 2,6-TDI vapours. The upper limit for this method is approximately 85 µg of TDI per sample. This is a conservative upper limit based on the requirement of maintaining a sufficient amount of reagent on the coated glass fibre filter while permitting a 4 h sample to be collected at 1 l/min from an atmosphere containing 50 nl/l of TDI. The quantitation limits for this method are 0,039 µg for 2,4-TDI and 0,034 μg for 2,6-TDI using a fluorescence detector. These limits, for a 15-min sample collected at 1 l/min, are equivalent to 0,36 nl/l for 2,4-TDI, and 0,32 nl/l for 2,6-TDI. For a 4 h sample collected at 1 l/min, the limits are equivalent to 0,022 nl/l for 2,4-TDI and 0,020 nl/l for 2,6-TDI. The commercial availability of the specified reagents, the use of common analytical instrumentation, and the current widespread use of the method make this standard method ideally suited for the determination of TDI in workplace environments.
