Plastics. Determination of tension-tension fatigue crack propagation. Linear elastic fracture mechanics (LEFM) approach1 Scope This International Standard specifies a method for measuring the propagation of a crack in a notched specimen subjected to a cyclic tensile load varying between a constant positive minimum and a constant positive maximum value. The test results include the crack length as a function of the number of load cycles and the crack length increase rate as a function of the stress intensity factor and energy release rate at the crack tip. The possible

Crosslinked Ethylene Tetra Fluoro Ethylene copolymer (XLETFE) greatly improves the surface resistance

Halon 1301 [bromotrifluoromethane (CF3Br)]

PD 7974-6:2004 is intended to provide guidance to designers

BS EN 61119-1 is the first part of the BS EN 61119 multi-series on digital audio tape cassette system that is applicable to the digital audio tape (DAT) cassette system that records and/or plays back digital information such as PCM encoded audio and/or other data

The first part does not cover more detailed technical aspects of the main concepts such as:

BS EN 3470 is part of the series of EN metallic material standards for aerospace applications

BS ISO 4141-2:2019 on test methods and requirements for high performance sheathed cables is useful for:

zinc aluminium and aluminium-zinc coating mass

as well as users of OHSAS 18001

The BS 1363-1 on rewirable and non-rewirable 13 A fused plugs part of the series sets out essential requirements for rewirable and non-rewirable 13 A fused plugs

on the factors which need to be considered when assessing the hazard to life and health presented by fires in structures (buildings and transport)

This document specifies requirements for precast concrete poles (also commonly called masts) (either all of a piece or composed of elements)
