This European Standard was approved by CENELEC on 2020-03-09. CENELEC members are bound to comply with the CEN/CENELEC
Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC
Management Centre or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CENELEC member into its own language and notified to the CEN-CENELEC Management Centre has the
same status as the official versions.

1 Scope
The object of this document is to determine the composition, nature of materials, manufacturing tests and
thermoelectronic behaviour of connectors for sensors using thermocouples according to EN 60584-3:2008.
This document does not cover such special thermocouples as U, L and W types; nevertheless, the user of
such special thermocouples can use the connectors described hereafter with some restrictions mentioned in
the relevant paragraphs.
