IEC 62321-3-2:2020 is available as IEC 62321-3-2:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 62321-3-2:2020 specifies the screening analysis of fluorine, chlorine and bromine in polymers and electronics using combustion-ion chromatography (C-IC). IEC 62321-3-2:2020 cancels and…

IEC 62321-3-2:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62321-3-2:2020 specifies the screening analysis of fluorine, chlorine and bromine in polymers and electronics…

This document specifies the test method for determination of the lead content in pyrotechnic compositions of fireworks by flame atomic absorption spectrophotometry, with a minimum detection limit of 10 mg/kg. It is generally recommended to perform a simple preliminary qualitative test to check whether a quantitative analysis is required.

This document specifies: — requirements on the physical layer at system level, — requirements on the interoperability test set-ups, — interoperability test plan that checks the requirements for the physical layer at system level, — requirements on the device-level physical layer conformance test set-ups, and — device-level physical layer conformance test plan that checks a set…

IEC 61970-301:2020 lays down the common information model (CIM), which is an abstract model that represents all the major objects in an electric utility enterprise typically involved in utility operations. By providing a standard way of representing power system resources as object classes and attributes, along with their relationships, the CIM facilitates the integration of network applications…

IEC 60079-25:2020 contains the specific requirements for design, construction and assessment of intrinsically safe systems, Type of Protection “i”, intended for use, as a whole or in part, in locations in which the use of Group I, II or III Ex Equipment is required. This document supplements and modifies the general requirements of IEC 60079-0 and the intrinsic safety standard IEC 60079-11.…

IEC 61970-301:2020 (E) lays down the common information model (CIM), which is an abstract model that represents all the major objects in an electric utility enterprise typically involved in utility operations. By providing a standard way of representing power system resources as object classes and attributes, along with their relationships, the CIM facilitates the integration of network…

1.1 This document specifies conditions for the determination of the reduced viscosity (also known as viscosity number) and K-value of PVC resins. It is applicable to resins in powder form which consist of homopolymers of the monomer vinyl chloride and copolymers, terpolymers, etc., of vinyl chloride with one or more other monomers, but where vinyl chloride is the main constituent. The resins may…

IEC 61753-1:2018+A1:2020 provides guidance for the drafting of performance standards for all passive fibre optic products. This document defines the tests and severities which form the performance categories or general operating service environments and identifies those tests which are considered to be product specific. Test and severity details are given in Annex A. This second edition cancels…
