DESCRIPTION
IEC 62321-11:2023
IEC 62321-11:2023 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.
