International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference EN 62059-31-1:2008
Title Electricity metering equipment - Dependability - Part 31-1: Accelerated reliability testing - Elevated temperature and humidity
Project Number 13671
Abstract/Scope IEC 62059-31-1:2008 provides one of several possible methods for estimating product life characteristics by accelerated reliability testing. In this standard, elevated, constant temperature and humidity is applied to achieve acceleration. The method takes into account the effect of voltage and current variation. It is applicable to all types of metering equipment for energy measurement, tariff and load control in the scope of IEC TC 13. The method given in this standard may be used for estimating (with given confidence limits) product life characteristics of such equipment prior to and during serial production. This method may also be used to compare different designs. The contents of the corrigendum of December 2008 have been included in this copy.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
