This European Standard specifies the requirements related to safety, including methods of rating and testingsingle-, two-, three-, four-leg and endless sewn flat woven webbing slings, with or without fittings, made ofpolyamide, polyester and polypropylene man-made fibre webbing in the width range of 25 mm to 450 mminclusive.The flat woven webbing slings covered by this Part of EN 1492 are intended for general purpose liftingoperations, i.e. when used for lifting objects, materials or goods which require no deviations from therequirements, safety factors or working load limits specified. Lifting operations not covered by this standardwould include the lifting of persons, potentially dangerous materials such as molten metal and acids, glasssheets, fissile materials, nuclear reactors and where special conditions apply.Flat woven webbing slings conforming to this European Standard are suitable for use and storage in thefollowing temperature ranges:a) polyester and polyamide-40~C to 100~C,b) polypropylene-40~C to 80~CThis European Standard does not apply to the types of webbing sling indicated below:a) slings such as bag slings, nets (consisting of several crossed webbings stitched together), 'adjustable' slings (containing, for example, intermediate buckles stitched along the webbing), etc.;b) slings made from webbing woven from monofilament yarns;c) slings designed for pre-slinging and intended not to be re-used;This European Standard deals with the technical requirements to minimize the hazards listed in clause 4which can arise during the use of flat woven webbing slings when carried out in accordance with theinstructions and specifications given by the manufacturer or authorized representative.
This standard specifies the procedure to determine the resistance to fluids for cable ties for harnesses for aerospace applications. It shall be used together with EN 4057-100.
This European standard specifies performance levels and test methods for the following characteristics of slide fasteners made from interlocking components mounted on textile tapes: strengths of puller attachment, closed-end, top stop, open-end slide fastener box,reciprocating mechanism, closed slide fastener when extended laterally, open-end attachment when extended laterally, slider lock, and open-end fastener single stringer slider retention. In addition performance levels are also specified for colour fastness to washing, dry cleaning and water, and for dimensional stability to washing and dry cleaning.
This document provides details of equipment, materials and procedure for performing the Strand in Cement test on a sample of glass fibre strand in a hardened cement environment.\nRequirements for glass fibres used as reinforcement in cements and concrete are defined in the European Standard Precast Concrete products - classification of GRC performances. It applies to continuous filament glass fibre products in the form of rovings, strands, or chopped strands and related products such as nets or chopped strand mats based on these products.
