Foreword
The text of document 44/572/FDIS, future edition 2 of IEC 61496-3, prepared by IEC TC 44, Safety of
machinery - Electrotechnical aspects, in collaboration with the Technical Committee CENELEC TC 44X,
Safety of machinery: electrotechnical aspects, was submitted to the IEC-CENELEC parallel vote and was
approved by CENELEC as CLC/TS 61496-3 on 2008-03-01.
This Technical Specification supersedes CLC/TS 61496-3:2003.
The most important changes and improvements compared to CLC/TS 61496-3:2003 are:
– extension of the range of detection capability covered by this part of the standard from 50 mm to
100 mm to the range of 30 mm to 200 mm;
– clarification of requirements for the selection of multiple detection zones (Clause A.10);
– more detailed information about the use of an AOPDDR as a whole body trip device by extension of
Clause A.12 and a new Clause A.13;
– improved description of the relationship between ranging accuracy and probability of detection
(Annex BB).
This Technical Specification is to be used in conjunction with EN 61496-1.
The following date was fixed:
– latest date by which the existence of the CLC/TS
has to be announced at national level (doa) 2008-06-01
Annex ZA has been added by CENELEC.
