标准范围

IEC 62499:2021给出了新制造的受电弓接触带的测试方法规则。并非所有测试都与接触条的某些设计相关。本文件不包括使用特定受电弓的试验。为了确定特定应用的适用性，可能需要进行超出本文件范围的额外补充测试，并且由客户和制造商事先商定。它基于EN 50405:2015。这第二版取消并取代了2008年出版的第一版。与上一版相比，此版本包括以下重大技术变更:a.标题已修改；b.本标准范围由碳接触条变更为接触条；c.替换几个参考标准；d.介绍了几个术语和缩写术语；-根据按重量计的金属或碳含量引入金属化接触带和金属接触带的定义；-介绍了接触带结构和类型的定义；e.介绍了数据表的要求；f.介绍了表1:测试时间表和表2:测试顺序；g.更新了某些试验方法和试验验收标准的要求；h.增加了金属化接触带金属含量测试、摩擦系数测试、碳材料抗冲击性可选测试、磨损性能可选测试；-引入附件A和附件B。

IEC 62499:2021 gives rules for testing methods for newly manufactured pantographs contact strips. Not all tests may be relevant to some designs of contact strips. This document excludes tests using a particular pantograph. Additional supplementary tests, out of the scope of this document, may be necessary to determine suitability for a particular application and are by prior agreement between customer and manufacturer.
It is based on EN 50405:2015. This second edition cancels and replaces the first edition published in 2008. This edition includes the following significant technical changes with respect to the previous edition:
a. Title modified;
b. The scope of this standard is changed from carbon contact strips to contact strips;
c. Replacement of several reference standards;
d. Several terms and abbreviated terms are introduced;
- The definitions of metalized contact strip and metal contact strip are introduced according to the metal or carbon content by weight;
- The definitions of contact strip structures and types are introduced;
e. Requirements for data sheets are introduced;
f. Table 1: Schedule of tests and Table 2: Sequence of tests are introduced;
g. the requirements for certain test methods and test acceptance criteria are updated;
h. Test of metal content for metalized contact strip, test of the coefficient of friction, optional test of the impact resistance of the carbon material and optional test of wear properties are added;
- Annex A and Annex B are introduced.
