Information technology — Metadata registries (MDR) — Part 30: Basic attributes of metadata
This document specifies basic attributes which are required to describe data elements and associated metadata, and which might be used in situations where a complete ISO/IEC 11179-3 metadata registry is not appropriate (e.g. in the specification of other International Standards).
Electromechanical elementary relays - Part 1: General and safety requirements
IEC 61810-1:2015 applies to electromechanical elementary relays (non-specified time all-or-nothing relays) for incorporation into low voltage equipment (circuits up to 1 000 V alternate current or 1 500 V direct current). It defines the basic functional and safety requirements and safety-related aspects for applications in all areas of electrical engineering or electronics, such as: general…
Test on gases evolved during combustion of materials from cables - Part 2: Determination of acidity ...
IEC 60754-2:2011+A1:2019 specifies the apparatus and procedure for the determination of the potential corrosivity of gases evolved during the combustion of materials taken from electric or optical fibre cable constructions by measuring the acidity (pH) and conductivity of an aqueous solution resulting from the gases evolved during the combustion. The general method specified in this standard is…
Test on gases evolved during combustion of materials from cables - Part 1: Determination of the halo...
IEC 60754-1:2011+A1:2019 specifies the apparatus and procedure for the determination of the amount of halogen acid gas, other than hydrofluoric acid, evolved during the combustion of compounds based on halogenated polymers and compounds containing halogenated additives taken from electric or optical fibre cable constructions. The method specified in this standard is intended for the testing of…

IEC 60335-2-116:2019 deals with the safety of furniture with electrically motorized parts intended for household and similar purposes, their rated voltage being not more than 250 V.
Furniture incorporating electrically motorised parts not intended for normal household use but which nevertheless may be a source of danger to the public, such as furniture intended to be used by laymen in shops,…
Measurement of smoke density of cables burning under defined conditions - Part 1: Test apparatus
IEC 61034-1:2005+A1:2013+A2:2019 provides details of the test apparatus to be used for measuring smoke emission when electric or optical fibre cables are burnt under defined conditions, for example, a few cables burnt horizontally. The light transmittance (lt) under flaming combustion and smouldering conditions can be used as a means of comparing different cables or complying with specific…
Information technology - Power efficiency measurement specification for data center storage
This document describes a standardized method to assess the energy efficiency of commercial storage products in both active and idle states of operation. A taxonomy is defined that classifies storage products in terms of operational profiles and supported features. Test definition and execution rules for measuring the power efficiency of each taxonomy category are described; these include test…
