BS 50999:1992 Foreword 前言 This Britishi Standard has been prepared under the direction of the cable and Insulation Standards policy Committee and supersedes BS 5099:1974 which is withdrawn.. 本标准是英国关于电线电缆行业的标准，取代BS 5099:1974 This edition of BS 5099 introduces a clause on calibration frequency, together with an associated annex on the procedure for checking the efficacy of the method of spark testing. 此版本的BS 5099在附件里增添了火花试机的校准周期以及校准的方法和程序。 This British Standard specifies spark testing of a wide range of cables, and , in as far as it is applicable, is equivalent to the spark testing specified in HD 21.2 and HD 22.2 for low voltage cables. 这个版本的BS 5099对电线电缆的绝缘火花试验作了很全面的说明，在很长时间内都是很适用的，在低压电线的火花测试与HD 21.2和HD 22.2是一样的。 Compliance with a British Standard does not of itself confer immunity from legal obligations. BS标准本身不能作为产品免检的法律依据。 Specification 规格说明 1 Scope 范围 This British Standard specifies requirements and test methods for a.c,d,c,high frequency and pulsed wave-form spark testing of the insulation and sheath of electric cables, The use of high frequency and pulsed wave-form testers is limited to cables rated less than 0.6/1KV,unless referred to in the cable specification. 这个标准是英国关于AC、DC、和高频以及脉冲电压对绝缘电线和护套的火花测试标准。高频或脉冲火花机是用于检测额定电压在0.6或1kV以下的电线。 2.References 参考 2.1 Normative references 标准参考 This British Standard incorporates, by reference, provisions from specific editions of other publications.
