1、电线电缆和软线参考标准REFERENCESTANDRDFORELECTRICALWIRESCABLESAND FLEXIBLE CORDSUL1581-2001上海电缆研究所电线电缆信息中心前言A：本标准包含美国保险商实验所（UL）产品的跟踪服务时涉及的产品基本要求，些产品受下列条文的限制，且处于本标准适用范围之内。这些要求是以可信的工程原理，研究成果。试验数据和现场经验以及对制造安装和使用的问题的评估为依据而制定的。这些依据来自向制造商，用户检验机构以及其它具有专业经验的人员咨询或是从他们处获的情报。上述对产品的要求可能由于经验丰富的研究人员深入而必须或是有必要进行修订。B：满足本标准对产品
2、的要求是制造商产品继续获得UL认证的条件之一。C：符合本标准条文的产品如果经检验发现还具有其它有损于本标准的安全水平的性能，则不一定认为符合本标准。D：采用本标准规定不同的材料制成的产品或是具有与本标准规定不同的结构的产品，可按本标准的要求的含义进行检验和测试，如果性能基本相同，则认为该产品符合本标准。E：UL按其宗旨履行职能时，不为制造商或是任何一方担当或开脱责任。UL的意见和调查结果是代表一种充分考虑到UL标准制定时实际运行的必要限制和工艺水平专业性评定，UL对此不负任何责任。如果因使用，解释UL标准或是其它依据而造成的损失包括重大损失，UL不负任何责任和义务。F：本UL标准规定的许多试验
3、本身具有一定的危险性，因此在做些试验时应采取恰当的人员和设备防护措施。导引1：范围1.1本标准包含橡皮绝缘电线电缆（UL44）热塑性料绝缘电线电缆（UL83）软线装置线（UL62）和用户引入电缆（UL854）等标准对于导体，绝缘，护套及其它护层的要求细则以及对于试样制备。样品选取，温度处理和测量与计算方法的要求细则。本标准的条文也被其它标准所引用。1. 2对于特定型号的电线电缆或软线的专用材料、结构、性能和标志的要求，载于相应的成品电缆标准中，本参考标准不包含这些内容。13如果本标准的某条文不适用的话，则相应的成品电缆的标准记载和规定了适用的条文。2：测量单位21本标准的每项数值要求附了以美国
4、惯用的英寸/磅单位表示以外，还以公制单位（实用SI制和惯用公制单位）表示，以命得该项要求可以方便地用于采用各种公制单位的国家。一项要求无论采用英制单位或公制单位，应得出相同（虽然不是严格等同）的结果。一项采用公制单位的要求应使用以公制单位校准的设备。 3：用语说明31本标准中采用的“电缆标准”这一用语，指任何引用本参考标准（UL1581）的成品电线、电缆或软线的标准。导体108000系列铝合金导体的要求101本节要求适用于采用8000系列电工级铝合金的退火或半退火铝线。允许的合金导体为64/0AWG实心导体和12AWG2000kcmil圆绞合导体和压缩/压紧绞合导体。102导线应由符合ASTM
