In 1997, 18 new "suitable measuring procedures" for 34 substances were issued by the bodies notified in accordance with the TRGS 402. Apart from a brief description of the sampling and analysing procedures, the achievable accuracy of the determination limits is outlined in a list. Measuring procedures for 25 of these substances are described in more detail in BIA's working folder on the measurement of hazardous substances. The procedures applying to the nine remaining substances have been integrated in the collection of analysing procedures approved by the German Berufsgenossenschaften (ZH 1/120). |
