The method described in this document quantifies the absolute exposure to mineral oil vapours and droplets, within a concentration range from 0,5 mg\/m3<\/sup> to 125 mg\/m3<\/sup>, in the inhalable fraction of the workplace air.<\/p>\n

This document contains comprehensive information and instructions on the equipment and chemicals to be used.<\/p>\n

This method is applicable for water soluble oils and metal working fluids.<\/p>\n
