94 INDUSTRIAL-PROCESS CONTROL – SAFETY OF ANALYSER HOUSES
96 FOREWORD
97 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
98 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
99 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
100 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
101 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
102 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
103 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
104 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
105 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
106 2) The formal decisions or agreements of IEC
