IEC TS 62738:2018(E) sets out general guidelines and recommendations for the design and installation of ground-mounted photovoltaic (PV) power plants. A PV power plant is defined within this document as a grid-connected, ground-mounted system comprising multiple PV arrays and interconnected directly to a utility’s medium voltage or high voltage grid. Additional criteria is that PV power plants…

IEC 61753-1:2018 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 and…

This document establishes specifications for the execution of tension tests to be carried out on an anchor grouted in the ground, as defined in EN 1997-1 and EN 1537. Three methods of testing are recognized by this document. Test Method 1 involves cyclic tension loading with measurement of displacement at the load stages; Test Method 2 involves cyclic tension loading with measurement of load loss…

This document specifies the method and apparatus for: — the measurement of the delta ferrite content, expressed as Ferrite Number (FN), in largely austenitic and duplex ferritic-austenitic stainless steel[1] weld metal through the attractive force between a weld metal sample and a standard permanent magnet; — the preparation and measurement of standard pads for manual metal arc…

This document establishes procedures and guidelines for the measurement and classification of mechanical vibration of reciprocating compressor systems. The vibration values are defined primarily to classify the vibration of the compressor system and to avoid fatigue problems with parts in the reciprocating compressor system, i.e. foundation, compressor, dampers, piping and auxiliary equipment…

IEC 62446-1:2016+A1:2018 defines the information and documentation required to be handed over to a customer following the installation of a grid connected PV system. It also describes the commissioning tests, inspection criteria and documentation expected to verify the safe installation and correct operation of the system. It is for use by system designers and installers of grid connected solar…

This document defines terms used in the ISO 21043 series of standards.

This document reviews approaches for processing and coding of HDR/WCG video content. The purpose of this document is to provide a set of publicly-referenceable methods for the operation of AVC or HEVC video coding systems adapted for compressing HDR/WCG video for consumer distribution applications. This document first includes a review of the video usability information (VUI) indicators and…

This document provides guidance on the processing of high dynamic range (HDR) and wide colour gamut (WCG) video content. The purpose of this document is to provide a set of publicly referenceable recommended guidelines for the operation of AVC or HEVC video coding systems adapted for compressing HDR/WCG video for consumer distribution applications. This document includes a description of…

ISO/IEC 7811 defines the characteristics for identification cards as defined in Clause 3 of this document and the use of such cards for international interchange. This document specifies requirements for a high coercivity magnetic stripe (including any protective overlay) on an identification card, the encoding technique and coded character sets. It takes into consideration both human and machine…
