This document describes a method for defining requirements for plastic materials used in extrusion-based additive manufacturing (AM) processes. Materials include unfilled, filled, and reinforced plastic materials suitable for processing into parts. These materials can also contain special additives (e.g. flame retardants, stabilizers, etc.). Processes include all material extrusion-based AM processes.
This document is intended for use by manufacturers of materials, feedstocks, plastic parts or ...view more

This Technical Specification describes specific functional recommendations for the safe
design, handling, installation and operation of unplasticized polyamide (PA-U) gas piping
systems with fusion jointing and mechanical jointing with
a)  a maximum operating pressure (MOP) up to and including 16 bar;
b)  an operating temperature between -20 °C and +40 °C.
This Technical Specification covers PA pipes single layer solid wall.

This European standard specifies test methods for determination
of the suitability of two component epoxy and polyurethane
adhesives for on-site repair of cracked timber structures. The
standard specifies minimum requirements on bond strength and
integrity. The standard provides minimum on-site repair
provisions and specifies test and minimum strength
requirements with drill cores from on-site repaired timber
structures for verification of bond
strength and integrity.

In recent years, a number of representatives have been appointed by the CEN/CENELEC Governing Bodies (AGs, CAs, BTs) to represent the interests of CEN/CENELEC in external groups (e.g. European Commission Expert groups) and specific events (e.g. UN/EC, conferences).
Given the important role that these representatives play, it is necessary to define their roles and responsibilities and make them aware of the expected commitment, in order to ensure that they:
- act in line with the CEN and CENELE...view more

IEC TR 62914:2014 identifies experimental procedures for the forced internal short-circuit tests in terms of designation, dimensions, tests and requirements. This technical report provides supplemental information to perform the forced internal short-circuit test of IEC 62133:2012 (Subclause 8.3.9).

IEC 60773:2021 applies to test methods for the measurement of the operational characteristics of brushes designed to operate on commutating and slip ring machines under specified test conditions. By extension some tests may be relevant for other kinds of sliding electrical contacts for electrical appliances.
This second edition cancels and replaces the first edition published in 1983. This edition includes the following significant technical changes with respect to the previous edition:

IEC 61752-111-08:2021 contains the minimum tests, test severities and measurement requirements which a sealed fibre optic closure need to meet in order to be categorised as meeting the IEC standard for category G - Ground, as defined in Table A.14 of IEC 61753-1:2018. Free breathing closures are not covered in this document. This first edition cancels and replaces IEC 61753-111-8 published in 2009. This edition constitutes a technical revision. This edition includes the following significant tec...view more

IEC 60809:2021 is applicable to electric light sources for use in automotive applications, for example in road illumination devices and/or light signalling devices for road vehicles.
It is especially applicable to light sources listed in UN Resolution R.E.5 and light sources subject to other legislations.
This fourth edition cancels and replaces the third edition published in 2014, Amendment 1:2017, Amendment 2:2017 and Amendment 3:2019. This edition constitutes a technical revision.

IEC 63203-201-3:2021 specifies a test method for determination of the electrical resistance of conductive fabrics under simulated microclimate within clothing. The microclimate is the climate of the small air layer between the skin and clothing having a specific temperature and humidity. This test method can be applied to conductive fabrics including multilayer assemblies for use in clothing.

IEC 62899-402-3:2021(E) specifies the optical measurement method for acquiring two-dimensional images of voids and obtaining the void-related attributes in the dried or cured printed patterns which are part of the electronic products in the field of printed electronics. The measurable voids using this document are limited to those that are distinguishable by the optical image measurement.
NOTE In this document, void means an imperfection of pattern observed from a two-dimensional (2D) top-view.

IEC 63229:2021(E) gives guidelines for the definition and classification of defects in GaN epitaxial film grown on SiC substrate. They are identified and described on the basis of examples, mainly by schematic illustrations, optical microscope images, and transmission electron microscope images for these defects. This document covers only defects in as-grown GaN epitaxial film on SiC substrate and does not include defects caused by subsequent processes.

IEC 60794-3-70:2021 is available as IEC 60794-3-70:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60794-3-70:2021 covers outdoor optical fibre cables intended for rugged terrestrial rapid/multiple deployment. These cables, with enhanced mechanical, environmental and ingress performance can be used wherever a rapid or multiple deployment is relevant (e.g. mobile broadcast units, emergenc...view more

IEC PAS 61162-103:2021 supports the transfer of data between various equipment. This document specifies more equipment Talker IDs, amends existing sentences and introduce new sentences to facilitate more functionality between equipment.
