BS EN IEC 62321-11:2024

This standard BS EN IEC 62321-11:2024 Determination of certain substances in electrotechnical products is classified in these ICS categories:

• 13.020.01 Environment and environmental protection in general
• 43.040.10 Electrical and electronic equipment

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 ℃. NOTE TCEP starts thermal decomposition at approximately 230 ℃. 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).
