Examples Of Using Latest Ics Standard From ISO and IEC

Fibre optic interconnecting components and passive parts - Performance standard Part 085-02 - Non-connectorized single mode pigtailed CCWDM devices for category C indoor controlled environment (IEC 617533-085-02/2021)EN IEC 617533-085-02/20221

IEC 61753-085:02:2021 specifies the minimum initial measurement and test requirements that a fibre-optic pigtailed coarse wavelength division multiplexing device (CWDM) must meet in order to be classified as meeting the requirements for category C (indoor controlled environments), as described in Annex A to IEC 61753-1.2018. IEC 62074-1 defines CWDM. This is the first edition that cancels and replaces IEC 617533-085-2, which was published in 2008. This edition is a technical revision. This edition contains the following technical change in respect to IEC61753-085-2. Change of test conditions that harmonize with IEC 61753-1.2018.

Optical fibre cable specification - Optical cable elements and fibre ribbon (IEC 60794-1-31:2021)

EN IEC 60794-1 - 31:2021

This section of IEC 60794, which serves as a generic specification, deals with optical fibre ribbons. These requirements apply to optical fiber ribbon cables for use in telecommunication equipment, and devices employing similar technologies. IEC 60794-2 is for indoor use. IEC 60794-3 is for outdoor use. IEC 60794-4 is for self-supporting overhead use. IEC60794-4 is for indoor/outdoor. IEC60794-4 is for air blown. You can find detailed specification in the documents of specification for each application, such as IEC60794-2 or IEC 60794-3. See this Collection of standard from ISO, IEC, CEN, CENELEC, ETSI, and SIST for examples.

Fixed inductors for electromagnetic interference suppression Part 2: Sectional specification of power line chokes (IEC60938-2:2021)

EN IEC 60938-2.2021

This standard applies to fixed-inductors that are designed to suppress electromagnetic interference. They will be connected to an AC mains supply or another supply with a nominal voltage of not more than 1000 V AC r.m.s. or 1500 V DC with no nominal frequency exceeding 400 Hz.

This International Standard only applies to inductors that are fixed and have passed safety tests. Inductors that conform to this specification can be connected to mains supply when Annex A's mandatory tests are necessary or used in other circuit positions in which the equipment specification requires that they pass all or some of the safety tests.

Plain bearings Lubrication holes and grooves and pockets Dimensions, types and application to bearing bush

ISO 12128.2020

This document contains the dimensions of lubrication holes, grooves, and pockets for bearing bush bushes. You can enter these dimensions on drawings using the designation examples. They are used depending on the operating conditions.

It also allows the user to set the lubricant feed and distribution for both steel-backed plain bearing bush bushes and bushes with a steel backing made of copper alloys and aluminium alloys.

Because plain bearing bushes made from sintered metals are soaked in lubricant, it is not possible to specify the lubricant feed or distribution. Plain bearing bushes made from artificial carbon do not require oil or grease to lubricate.

Commercial kitchen fire extinguishing systems - Design, documentation and testing requirements

EN 17446.2021

This document outlines the minimum requirements for the design, installation and functioning of fixed automatic fire extinguishing system for kitchen protection. It covers the kitchen appliances as well as the plenum, exhaust ducts, and the hood.

This document also contains requirements for performance of components and construction as they relate to certain types, sizes, and arrangements of pre-engineered kitchen-fire-extinguishing system.

This document does NOT cover industrial food production equipment or household kitchens.

Information and documentation -- Guidelines to bibliographic references and citations of information resources

ISO 690.2021

This document outlines a set of guidelines and principles for the preparation and publication of bibliographic references in works that are not primarily bibliographical. This document is applicable to bibliographic citations and bibliographical references for all types of information resources including monographs, serials. A contributions within monographs. serials. Patents. Cartographic materials. Performances. Music.

Part 215: High-voltage controlgear and switchgear - Phase comparator for VDIS (IEC 622271-215.2021)

EN IEC 622271-215.2021

IEC 622711-215:2021 applies to phase comparators that are plugged into the testing points for a voltage detecting system (VDIS), according to IEC 622711-213 to show the results of a phase analysis. This is used to show the phase relationship between two energized components of a high voltage network at the same nominal voltage before coupling them. This edition replaces the 1997 edition of IEC 61243-5 and the 2011 edition of IEC62271-206. This edition combines the contents of IEC 61243-5 with IEC 62271-206. This edition contains the following technical changes in comparison to previous editions IEC 61243-5 or IEC 62271-206. The document does not include specific phase comparators (SPCs), which were specific to manufacturers. It also takes back the technical principles for the universal phase comparator, (UPC), for VDIS of all manufacturer; the phase comparator is introduced for sequential connected operation to allow phase comparation of large-sized MV panels.
