IEC 60335-2-108:2024 deals with the safety of electrolysers that produce low viscosity, ionized liquids intended for use as detergent free wash water in appliances for household and similar purposes and which conform with the standards applicable to such appliances. It applies to electrolysers tested separately, under the most severe conditions that can be expected to occur in normal use, their…

IEC 62977-2-7:2024 specifies standard measuring conditions and measurement methods for determining the optical characteristics of tiled displays which consist of multiple display modules in order to form one screen. These methods apply to emissive and transmissive direct view flat displays that render real 2D images with all modules lying in the same plane. The methods are applicable in…

IEC 61784-5-12:2024 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 61784-5-12:2024 specifies the installation profile for CPF 12 (EtherCAT™). The installation profile is…

This document specifies design, type test methods, marking and instruction requirements for cylinder valves with integrated pressure regulators (VIPRs) intended to be fitted to gas cylinders, pressure drums or tubes or used as a main valve for bundles of cylinders that convey compressed, liquefied or dissolved gases. These are requirements for VIPRs that are in addition to those given in the…

This document specifies procedures suitable for the analysis of data which, when converted into logarithms of the values, have either a normal or a skewed distribution. It is intended for use with test methods and referring standards for glass-reinforced thermosetting plastics (GRP) pipes or fittings for the analysis of properties as a function of time. However, it can also be used for the…
