标准范围

IEC 62321-11:2023规定了测定塑料中磷酸三（2-氯乙基）酯（TCEP）的两种不同技术，即GC-MS或LC-MS方法，这两种方法都适用于定量分析。这两种技术适用于含有200 mg/kg至2000 mg/kg TCEP的聚氨酯、聚氯乙烯和聚乙烯材料。这些试验方法不适用于加工温度高于230°C的塑料材料。使用热解器/热解吸附件（Py/TD-GC-MS）技术的GC-MS如附件a所述，可用于塑料中TCEP的筛选。

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.
