本標準規定了使用威特曼鼓輪和六足滾筒試驗儀在機械方式的作用下,使地毯產生毯面結構的變化和色彩變化的試驗程序。地毯由鼓輪試驗機產生的外觀變化按照GB/T 26845進行評價。本標準適用于所有需進行外觀變化評價的地毯產品。
本標準規定了機動車兒童乘員用約束系統(以下簡稱兒童約束系統)的術語和定義,在車輛上的安裝及固定要求,約束系統的結構,以及對約束系統總成及其組成部件的性能要求和試驗方法。本標準適用于適合安裝在三個車輪或機動車的兒童乘員用約束系統,但不適用于安裝在折疊座椅或側向座椅上的兒童約束系統。
本標準規定了絕緣外徑在1mm以下的極細同軸電纜(以下簡稱電纜)及組件(以下簡稱組件)的要求、試驗方法、檢驗規則、標志和包裝等要求。本標準適用于通訊設備或類似電子裝置內部模塊間或設備之間工作頻率范圍為DC~6000MHz的短距離連接電纜及由此類電纜與連接器組成的組件。
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.
