Fire resistance tests — Fire dampers for air distribution systems — Part 2: Intumescent dampers
This document specifies a test method for the determination of the resistance of fire dampers to heat, and for the evaluation of their ability to prevent fire and smoke from spreading from one fire compartment to another through an air distribution system.
This document describes the test requirements related to intumescent fire dampers. It is intended for intumescent fire dampers that are…
Diesel engines — Cleanliness assessment of fuel injection equipment
This document specifies cleanliness assessment procedures for evaluating the amount of debris found within the clean side of diesel fuel injection assemblies, which could lead to a reduction in the system’s operational effectiveness.
While other International Standards, e.g. ISO 16232, relate to cleanliness of components used in road vehicle fluid circuits, this document is focused on diesel fuel…
Plastics — Film and sheeting — Biaxially oriented polypropylene (PP) films
This document specifies the requirements for biaxially oriented polypropylene (PP) films, which are mainly used for packaging. The film can be used alone or in laminates with other films.
This document applies only to films composed of more than 95Â % (by mass) of polypropylene.
Direct current (DC) appliance couplers for information and communication technology (ICT) equipment ...
IEC TS 63236-1:2021(E) applies to DC appliance couplers for class I equipment with two active contacts plus an earthing contact, a rated power of 2,6 kW and a rated voltage range from 294 V to 400 V DC. They are intended to power DC information and communication technology equipment only, as specified in IEC 62368‑1.
Direct current (DC) appliance couplers for information and communication technology (ICT) equipment ...
IEC TS 63236-3:2021(E) sets the additional requirements for appliance inlets used for information and communication technology (ICT) equipment installed in data centres and telecom central offices and which are suitable for both alternating current and direct current.
This Part 3 is to be used in conjunction with IEC TS 63236-1:2021.
Paper, board and printing inks – Printability – Laboratory test method for offset ink setting
This document describes a laboratory test method, using an IGT1-type or a prüfbau2-type printability tester, for the preparation of specimens to evaluate the absorption rate of an ink on a substrate in offset lithography by setting-off the printed surface to an unprinted surface.
This method describes testing with an amount of ink simulating either single colour or multi-colour printing. The…
Semiconductor devices - Discrete devices - Part 8: Field-effect transistors
IEC 60747-8:2010+A1:2021 gives standards for the following categories of field-effect transistors:
- type A: junction-gate type;
- type B: insulated-gate depletion (normally on) type;
- type C: insulated-gate enhancement (normally off) type.
The main changes with respect to the previous edition are listed below.
a) "Clause 3 Classification" was moved and added to Clause 1.
b)…
Direct current (DC) appliance couplers for information and communication technology (ICT) equipment ...
