CEN/TS 13130-17:2005

Materials and articles in contact with foodstuffs - Plastics substances subject to limitation - Part 17: Determination of carbonyl chloride in plastics

Scope

This document, part of EN 13130, specifies an analytical procedure for the determination of carbonyl chloride monomer in polymers. The method is applicable to polycarbonate as well as to other polymers and copolymers where these are soluble in methylene chloride. The level of carbonyl chloride monomer determined is expressed as milligrams of carbonyl chloride per kilogram of polymer. The method is appropriate for the quantitative determination of carbonyl chloride at a minimum level of 0,3 mg per kilogram of polymer.
