The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising 
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote 
international co-operation on all questions concerning standardization in the electrical and electronic fields. To 
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, 
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC 
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested 
in the subject dealt with may participate in this preparatory work. International, governmental and nongovernmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely 
with the International Organization for Standardization (ISO) in accordance with conditions determined by 
agreement between the two organizations
