GB/T 5013的本部分適用于額定電壓U<下標 0>/u為450/750 V及以下,硫化橡皮絕緣和護套(若有)的硬和軟電纜,用于交流額定電壓不超過450/750 V的動力裝置。 注:對某些型號的軟電纜可使用術語“軟線”。 各種型號的電纜在GB/T 5013.3、GB/T 5013.4等部分中規定,電纜的型號表示法見附錄A。 GB/T 5013的第1至第8部分規定的試驗方法見GB/T 5013.2、GB/T 18380.1及GB/T 2951的相關部分。
GB/T 5023的本部分詳細規定了額定電壓450/750V及以下固定布線用聚氯乙烯絕緣單芯無護套電纜的技術要求。所有電纜應符合GB/T 5023.1規定的相應要求,并且各種型號電纜應分別符合本部分規定的特殊要求。
1.1 本規則適用的產品范圍a) 礦用橡套軟電纜;b) 交流額定電壓3kV 及以下鐵路機車車輛用電線電纜;c) 額定電壓450/750V 及以下橡皮絕緣電線電纜;d) 額定電壓450/750V 及以下聚氯乙烯絕緣電線電纜。1.2 本規則不適用的產品范圍本規則不適用于電線組件產品,也不適用于裸電線、電力電纜、架空絕緣電纜、通信電纜、光纜、繞組線產品。
This Part of EN 1366 specifies a method of test and criteria for the evaluation (including field ofapplication rules) of the ability of a penetration seal to maintain the fire resistance of a separatingelement at the position at which it has been penetrated by a service. Penetration seals used to sealgaps around chimneys, air ventilation systems, fire rated ventilation ducts, fire rated service ducts,shafts and smoke extraction ducts are excluded from this standard except for mixed penetrationseals. The fire resistance of those services itself cannot be assessed with the methods described inthis standard.Supporting constructions are used in this standard to represent separating elements such as walls orfloors. These simulate the interaction between the test specimen and the separating element intowhich the sealing system is to be installed in practice.This European Standard is used in conjunction with EN 1363-1.The purpose of this test described in this standard is to assess:a) the effect of such penetrations on the integrity and insulation performance of the separatingelement concerned;b) the integrity and insulation performance of the penetration seal;c) the insulation performance of the penetrating service or services, and where necessary, theintegrity failure of a service.No information can be implied by the test concerning the influence of the inclusion of suchpenetrations and sealing systems on the loadbearing capacity of the separating element.It is not the intention of this test to provide quantitative information on the rate of leakage of smokeand/or hot gases or on the transmission or generation of fumes. Such phenomena are only to benoted in describing the general behaviour of test specimens during the test.This test is not intended to supply any information on the ability of the penetration seal to withstandstress caused by movements or displacements of the penetrating services.The risk of spread of fire downwards caused by burning material, which drips through a pipedownwards to floors below, cannot be assessed with this test.Explanatory notes to this test method are given in Annex H.All dimensions given without tolerances are nominal ones unless otherwise stated.
