Foreword
This document (CEN/TS 13130-17:2005) has been prepared by Technical Committee CEN/TC 194
“Utensils in contact with food”, the secretariat of which is held by BSI.
This part of EN 13130 has been prepared within the Standards, Measurement and Testing project,
MAT1-CT92-0006, “Development of Methods of Analysis for Monomers” and has been prepared by
Subcommittee (SC 1) of TC 194 "Utensils in contact with food" as one of a series of test methods for
plastics materials and articles in contact with foodstuffs.
This standard is intended to support Directives 2002/72/EC [1], 89/109/EEC [2], 82/711/EEC [3] and
its amendments 93/8/EEC [4] and 97/48/EC [5], and 85/572/EEC [6].
At the time of preparation and publication of this part of EN 13130 the European Union legislation
relating to plastics materials and articles intended to come into contact with foodstuffs is incomplete.
Further Directives and amendments to existing Directives are expected which could change the
legislative requirements which this standard supports. It is therefore strongly recommended that users
of this standard refer to the latest relevant published Directive(s) before commencement of a test or
tests described in this standard.
This part of EN 13130 should be read in conjunction with EN 13130-1.
Further parts of EN 13130, under the general title Materials and articles in contact with foodstuffs -
Plastics substances subject to limitation, have been prepared, and others are in preparation,
concerned with the determination of specific migration from plastics materials into foodstuffs and food
simulants and the determination of specific monomers and additives in plastics. The parts of
EN 13130 are as follows.

Introduction
Carbonyl chloride or phosgene, CCl O, PM/Ref. No 14380, is a monomer used in the manufacture of
certain plastics materials and articles intended to come into contact with foodstuffs. After manufacture,
residual carbonyl chloride can remain in the polymer and may migrate into foodstuffs coming into
contact with the plastics material or article.
The method has been pre-validated by a collaborative trial with two laboratories.
1 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.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
EN 13130-1:2004, Materials and articles in contact with foodstuffs – Plastics substances subject to
limitation – Part 1: Guide to test methods for the specific migration of substances from plastics to
foods and food simulants and the determination of substances in plastics and the selection of
conditions of exposure to food simulants.
3 Principle
The level of carbonyl chloride in the polymer is determined by dissolution of the polymer and
concurrent derivatization with 2-aminophenol. The resulting 2-benzoxazolinone is analyzed by high
performance liquid chromatography (HPLC) with ultra violet (UV) detection. Quantification is achieved
by standard addition of carbonyl chloride to the test polymer. Confirmation of the identity of carbonyl
chloride is carried out by diode array detection.
4 Reagents
NOTE 1 Carbonyl chloride reacts rapidly with moisture. Suitable precautions should be taken to protect
carbonyl chloride solutions from moisture. The carbonyl chloride derivative is not sensitive to moisture.
NOTE 2 All reagents should be of recognized analytical quality unless otherwise stated.

NOTE The water content of the toluene should be as low as possible. Toluene dried over a molecular sieve
can be obtained from chemical suppliers. Alternatively, toluene can be dried before use, in which case the
molecular sieve should be activated for maximum water absorption.
