    Abstract：In order to understand the evaluation of bunched combustion tests for two kinds of flame-retardant cables on their combustion behaviors，the development history and differences of the two test methods are analyzed；the test results of 5 kinds of cable samples show that：the bunched combustion test achieves preliminary evaluation on the combustion performance of flame-retardant cables，while FIPEC test can describe the combustion performance of flame-retardant cables in a relatively comprehensive way，which provides multiple data for the grading evaluation on flame-retardant cables.

    Key words：flame-retardant cable；bunched combustion test；FIPEC test；GB / T 31248；GB / T 18380；test method；test sample；grading evaluation

  摘 要：为系统地了解两种阻燃电缆成束燃烧试验方法对阻燃电缆燃烧行为的评价，梳理了两种试验方法的发展历程和差异；5种电缆样品试验结果表明：成束燃烧试验对阻燃电缆的燃烧性能进行初略评价，FIPEC试验能够较为全面描述阻燃电缆的燃烧性能，为分级评价阻燃电缆提供多个数据。
