65 FOREWORD
66 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national
67 electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all
68 questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities,
69 IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS)
70 and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC
71 National Committee interested in the subject dealt with may participate in this preparatory work. International,
72 governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC
73 collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined
74 by agreement between the two organizations.
75 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus
76 of opinion on the relevant subjects since each technical committee has representation from all interested IEC National
77 Committees.
78 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in
79 that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC
80 cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
81 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to
82 the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and
83 the corresponding national or regional publication shall be clearly indicated in the latter.
84 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment
85 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
86 independent certification bodies.
87 6) All users should ensure that they have the latest edition of this publication.
88 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of
89 its technical committees and IEC National Committees for any personal injury, property damage or other damage of any
90 nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication,
91 use of, or reliance upon, this IEC Publication or any other IEC Publications.
92 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable
93 for the correct application of this publication.
94 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights.
95 IEC shall not be held responsible for identifying any or all such patent rights.

114 INTRODUCTION
115 The widespread use of electrotechnical products has drawn increased attention to their impact on the
116 environment. In many countries this has resulted in the adoption of regulations affecting wastes,
117 substances and energy use of electrotechnical products.
118 The use of certain substances (e.g. lead (Pb), cadmium (Cd) and polybrominated diphenyl ethers
119 (PBDEs)) in electrotechnical products is a source of concern in current and proposed regional legislation.
120 The purpose of the IEC 62321 series is therefore to provide test methods that will allow the
121 electrotechnical industry to determine the levels of certain substances of concern in electrotechnical
122 products on a consistent global basis.
123 This first edition of IEC 62321-14 introduces a new subject covering short-chain chlorinated paraffins
124 (SCCPs) and medium-chain chlorinated paraffins (MCCPs) in the IEC 62321 series.
125 WARNING — Persons using this International Standard should be familiar with normal laboratory
126 practice. This International Standard does not purport to address all of the safety problems, if any,
127 associated with its use. It is the responsibility of the user to establish appropriate safety and health
128 practices and to ensure compliance with any national regulatory conditions.

136 1 Scope
137 This part of IEC 62321 specifies one technique for the determination of short-chain and medium-chain
138 chlorinated paraffins (SCCPs: C10-C13 and MCCPs: C14-C17) in plastics of electrotechnical products.
139 This standard specifies a quantitative method for the determination of short-chain and medium-chain
140 chlorinated paraffins in electrotechnical products by means of solvent extraction and gas
141 chromatography-negative chemical ionization-mass spectrometry (GC-NCI-MS).
142 This test method has been evaluated for use with ABS (acrylonitrile butadiene styrene) and PVC
143 (polyvinyl chloride) containing individual SCCPs ranging from 369,7 mg/kg to 8653,9 mg/kg and MCCPs
144 ranging from 2184 mg/kg to 27 329,6 mg/kg.
145 This standard is primarily intended for use by technical committees in the preparation of standards in
146 accordance with the principles laid down in IEC Guide 108.

215 8 Procedure

217 8.1.1 Ultrasonic extraction
218 a) The following steps shall be followed for sample extraction.
219 a) Accurately weigh a sample of 0,5 g and place test specimen into a 20 ml vial (6 c)). Sample weight
220 can be lowered to 0,1 g when the sample is expected to contain a high level of SCCPs or MCCPs
221 comparing to the highest level of calibration solution.
222 b) Add 5 ml of toluene (5 c)) to the vial and cap the vial tightly.
223 c) Place the vial in an ultrasonic water bath (6 k)) at (60 ± 5) °C for 60 min, and then allow the vial to
224 cool down to room temperature.
225 d) Add accurately 10 ml of n-hexane (5 b)) to precipitate the sample matrix and filter the solution
226 through a 0,45 µm membrane filter (6 e)).
227 e) Transfer 5 ml of the filtrate into 20 ml vial and evaporate to near dryness with nitrogen (5 k)) using
228 an evaporation apparatus (6 d)).
229 f) Add 2 ml internal solution B (5 g)) to redissolve the residue using a vortex agitator (6 f)) for 30 s,
230 and filter the solution through a membrane (6 e)) to be ready for sulfuric acid clean-up.
231 b)
IEC CDV 62321-14 © IEC 2024 – 11 – 111/802/CDV
8.1.2 Alternative extraction procedures
233 c) For a toluene insoluble polymer (e.g. PVC), the following alternative extraction procedure may
234 be applied.
235 a) Accurately weigh a sample of 0,5 g and place test specimen into a 20 ml vial (6 c)). Sample weight
236 can be lowered to 0,1 g when the sample is expected to contain a high level of SCCPs or MCCPs
237 comparing to the highest level of calibration solution.
238 b) Add 5 ml of toluene (5 c)) to the vial and cap the vial tightly.
239 c) Place the vial in an ultrasonic water bath (6 k)) at (60 ± 5) °C for 60 min, and then allow the vial to
240 cool down to room temperature.
241 d) Transfer 2 ml of the extract into 20 ml vial and evaporate to near dryness with nitrogen (5 k)) using
242 an evaporation apparatus (6 d)).
243 e) Add 2 ml internal solution B (5 g)) to redissolve the residue using a vortex agitator (6 f)) for 30 s,
244 and filter the solution through a membrane (6 e)) to be ready for sulfuric acid clean-up.
246 8.1.3 Clean-up procedure
247 The sample extract is recommended to be cleaned-up by sulfuric acid in order to remove interference.
248 Take 1 ml of solution from the extract (8.1.1 f) or 8.1.2 e)), and add 0,5 ml of concentrated sulfuric acid
249 (5 h)), shake for 30 min using a horizontal shaker. After separation
