- Abstract

This part of ISO 16000 specifies a test method for sampling and analysis of phosphoric acid esters in indoor air, and in test chamber air by gas chromatography/mass spectrometry. Both principle methods of the low resolution mass spectrometry and the high resolution mass spectrometry are described. Such multiplex applicability of the organophosporus compounds (OPCs) leads to the effect that large indoor areas with OPC containing building materials, varnishes, paints, floor care products or fire protection coatings can be encountered. Due to their varying physical and physical-chemical properties, OPC can be detected also in the indoor transfer media (dust and air). As a rule, OPCs boiling at high temperatures such as tris(2-butoxyethyl) phosphate (TBEP) can be found in relevant concentrations in indoor air, only if the emission source shows higher temperatures. In the case of sources exposed to higher temperatures (e. g. screens or roller blinds for sun protection), consideration should be given also to the different source temperatures under normal conditions of use when the emission situation is assessed. Acid esters are incorporated in hardeners and accelerants, in mordant and adhesion boosting agents and serve as cleaning, corrosion inhibition and adhesion facilitating substances by the treatment of metal surfaces. They are used as auxiliary means in paper and textiles, as wetting and defoaming agents, emulsifiers, stabilizers, as additives to cleaning agents and detergents, as not readily flammable hydraulic liquids and as oil and fuel additives.
