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