This document specifies the requirements for the design, manufacture and testing of non‑reclosable pressure-relief devices for cryogenic service, i.e. for operation with cryogenic fluids in addition to operation at temperatures from ambient to cryogenic. This document is restricted to bursting‑disc and buckling‑pin devices not exceeding a nominal diameter size (DN) of 200 that are designed to relieve single‑phase vapours or gases. A bursting‑disc or buckling‑pin assembly can be specified, constructed and tested such that it is suitable for use with more than one gas or with mixtures of gases. NOTE This document does not provide methods for determining the capacity of bursting‑disc or buckling‑pin devices for a particular cryogenic vessel. Such methods are provided in ISO 21013-3.

This document establishes requirements on implementations that quantify how a face image’s properties conform with those of canonical face images, for example those specified in ISO/IEC 39794-5:2019, Clause D.1, for three use-cases: 1) collection of reference samples for ID documents; 2) sample system enrolment; and 3) probes for instantaneous response. This document also establishes terms and definitions for quantifying face image quality and specifies methods for quantifying the quality of face images. This document does not establish requirements on: — assessing the quality of pairs or sequences of images; NOTE This document establishes requirements for software that inspects exactly one image. This document does not establish requirements for software that compares two or more images (such as biometric recognition). However, the computations of this document can be applied separately to each image in a pair or sequence. — assessing the quality of 3D captures; — encodings of face image quality data; — performance evaluation of face image quality assessment algorithms. The use cases within scope of this document primarily address the assessment of images from data capture subjects who consent to processing of their biometric data, or for whom biometric capture is operationally authorized.

This document describes the reference software and conformance suite for the file format documents in multiple standards. Since these standards share a lot of technology, their reference software and conformance program are being handled together. These standards are: ISO/IEC 14496-12, ISO/IEC 14496-14, ISO/IEC 14496-15, ISO/IEC 14496-30 and ISO/IEC 23008-12. The purpose of the conformance suite is to cover the set of valid features that can be exercised in the file format. Media conformance is not covered, though of course to exercise the file format features, media will be stored.

This part of IEC 60079 specifies the construction and testing of intrinsically safe apparatus intended for use in an explosive atmosphere, and for associated apparatus which is intended for connection to intrinsically safe circuits which enter such atmospheres.
This Type of Protection is applicable to electrical equipment in which the electrical circuits themselves are incapable of causing ignition of a surrounding explosive atmosphere. This includes electrical equipment which contains circuits that are intrinsically safe only under certain conditions, for example under battery supply with mains supply removed.
This standard is also applicable to electrical equipment or parts of electrical equipment located outside the explosive atmosphere or protected by another Type of Protection listed in IEC 60079-0, where the intrinsic safety of the electrical circuits in the explosive atmosphere may depend upon the design and construction of such electrical equipment or parts of such electrical equipment. The electrical circuits exposed to the explosive atmosphere are assessed for use in such an atmosphere by applying this standard.
This standard applies to sensors connected to intrinsically safe circuits but does not apply to the protection of catalytic elements for Group IIC or Group IIB + H2.
The requirements for intrinsically safe systems are provided in IEC 60079-25.
This standard supplements and modifies the general requirements of IEC 60079-0, except as indicated in Table 1. Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of this standard takes precedence.
Unless otherwise stated, the requirements in this standard are applicable to both intrinsically safe apparatus and associated apparatus, and the generic term "apparatus" is used throughout the standard.
As this standard applies only to electrical equipment, the term "equipment" used in the standard always means “electrical equipment”.
This standard applies to apparatus for use under the atmospheric conditions of IEC 60079-0 with additional requirements for for use at lower atmospheric pressures in the range from 60 kPa (0,6 bar), up to 110 kPa (1,1 bar).

IEC 61643-01: 2024 contains the common requirements for all SPDs. This document is applicable to devices for surge protection against indirect and direct effects of lightning or other transient overvoltages, hereafter referred to as Surge Protective Devices (SPDs). SPDs are intended to be connected to circuits or equipment rated up to 1 000 V AC (RMS) or 1 500 V DC. Performance and safety requirements, tests and ratings are specified in this document. SPDs contain at least one nonlinear component and are intended to limit surge voltages and divert surge currents.

This International Standard applies to Source Switching Equipment, hereafter referred to as SSE(s), for household and similar uses, primarily intended to be used for Energy Efficiency purposes with local production and/or storage of energy. This standard has been drafted following principles of: - IEC guides 118 and 119 for Energy Efficiency; - IEC guide 110 for safety. SSEs are intended to be installed in low voltage prosumer electrical installations (PEI) to deliver the electrical energy: - either to current-using equipment (direct feeding mode or island mode); - or to the grid (reverse feeding mode). SSEs are intended to select and/or combine two power sources (e.g. selected among grid, local power source, storage units) within an Electrical Energy Management system (EEMS). SSEs may also be used for backup supply. NOTE SSEs capable to select more than two sources are under consideration. SSEs are part of the fixed electrical installation. This standard applies to SSEs for operation in: - AC single or multiphase circuits with rated voltages not exceeding 440 V AC, frequencies of 50 Hz, 60 Hz or 50/60 Hz and rated currents not exceeding 125 A. They are intended to be used in installations with prospective short circuit current not exceeding 25 000 A, or - DC circuits. SSE for DC circuits are under consideration (next edition). SSEs may be operated: - manually (M-SSE), or - remotely (R-SSE), or - automatically (A-SSE), or - a combination of the above methods of operation, e.g. manual and remote. SSEs are constructed either as Combined-SSEs (C-SSEs, based on dedicated products suc as circuit breakers, switches or contactors) or Non-Combined SSEs (NC-SSEs). SSEs are intended for use in circuits where protection against electrical shock and over-current according to IEC 60364 is provided, unless the SSE already contains such protective function. SSEs are normally installed by instructed persons (IEC 60050-195:1998, 195-04-02) or skilled persons (IEC 60050-195:1998, 195-04-01). SSEs are normally used by ordinary persons (IEC 60005-195:1998, 195-04-03) and do not require maintenance. The requirements of this standard apply for standard environmental 420 conditions as given in clause 7. They are applicable to SSEs intended for use in an environment with pollution degree 2 and overvoltage categories III according to IEC 60664-1:2020. SSEs have at least a degree of protection IP 20 according to IEC 60529. Additional requirements may be necessary for devices used in locations having more severe environmental conditions. SSEs do not, by their nature, provide an isolation function nor the overcurrent protection. However, isolation and overcurrent protection functions as covered by relevant product standards may be provided by Combined SSEs. In some countries, it is not permitted to have synchronization of local sources with the grid for particular grid conditions, e.g. when fluctuations of the grid voltage or frequency are outside the tolerance limits. This document does not apply to transfer switching equipment (TSE) intended to be used by skilled persons, as covered by IEC 60947-6-1:2021.
