NOTE Subclauses which are additional to those in IEC 60903 are prefixed “Z“. Annexes designated “normative“ are part of the body of the standard. Annexes designated “informative“ are given for information only. In this standard, annexes A, B, C and ZA are normative and annexes D, E, F, G, H and I are informative. Annex ZA has been added by CENELEC. Endorsement notice The text of the International Standard IEC 60903:2002 and its corrigendum February 2003 was approved by CENELEC as a European Standard with agreed common modifications. _ Page 2 EN

clauses on requirements and testing are reorganized in order to bring together the common requirements and tests, then to lay down separately those which are specific to insulating gloves for electrical protection normally worn under leather protector gloves as opposed to those specific to insulating gloves for combined electrical and mechanical protection. This arrangement meets the basic necessity that a same quality level of electrical insulation is achieved for all types of insulating gloves. This document has been prepared according to the requirements of IEC 61477 where applicable. Page 6 EN 60903:2003 LIVE WORKING GLOVES OF INSULATING MATERIAL 1 Scope This International Standard is applicable to: insulating gloves and mitts which should normally be used in conjunction with leather protector gloves worn over the insulating gloves to provide mechanical protection; insulating gloves and mitts usable without over-gloves for mechanical protection. Unless otherwise stated, the use of the term “glove” includes both gloves and mitts. The use of the term “insulating gloves” designates gloves providing electrical protection only. The use of the term “composite gloves” designates gloves providing electrical and mechanical protection. 2 Normative references The following referenced documents are indispensable for the application of this document.
