Abstract
1 Scope
This part of [IEC 62321](/search?q=IEC%C2%A062321)
specifies two different techniques for the determination of tris(2-chloroethyl) phosphate
(TCEP) in plastics , the GC-MS or LC-MS method, both of which are applicable to quantitative analysis.
These two techniques are applicable to use with polyurethane, polyvinylchloride, and
polyethylene materials containing TCEP between 200 mg/kg to 2 000 mg/kg.
These test methods do not apply to plastic materials having a processing temperature higher than 230 °C.
GC-MS using a pyrolyser/thermal desorption accessory ( Py/TD-GC-MS ) technique is described in Annex A and can be used for the screening of TCEP in plastics .
NOTE
TCEP starts thermal decomposition at approximately 230 °C. Polymer types that have a processing temperature into shapes of plastics (e.g. pellets, moulded parts or sheets) not exceeding the decomposition temperature
can contain TCEP.
