This part of IEC 62321 specifies two different techniques for the determination of TCEP tris(2-chloroethyl) phosphate (TCEP) in plastics, the GC-MS or LC-MS method; both of which are suitable for quantitative analysis. These two techniques have been evaluated for use with polyurethane, Polyvinyl chloride and polyethylene materials containing TCEP between 200 mg\/kg to 2 000 mg\/kg. Use of the methods escribed in International Standard for other polymers and concentration ranges has not been specifically evaluated. These test methods do not apply to plastics materials having a processing temperature higher than 230 \u2103. NOTE TCEP starts thermal decomposition at approximately 230 \u2103. Polymer types which have a processing temperature into shapes of plastics (e.g. pellets, moulded parts, or sheets etc.) not exceeding the decomposition temperature can contain TCEP. Py-TD-GC-MS is another technique, suitable for the screening of TCEP in plastics (See Annex A).<\/p>\n
