IEC 61482-2:2009标准要求电弧热防护服装必须符合以下要求：

1. 保护等级
电弧热防护服装必须能够提供足够的保护等级，以保护穿着者免受电弧热的伤害。标准规定了两个保护等级：ATPV（Arc Thermal Performance Value）和EBT（Energy Breakopen Threshold）。ATPV是指电弧热能量的最大值，EBT是指电弧热能量的最小值。电弧热防护服装必须能够提供足够的ATPV和EBT，以保护穿着者免受电弧热的伤害。

2. 测试方法
电弧热防护服装必须经过一系列的测试，以确保其符合标准要求。测试包括：电弧热能量测试、燃烧测试、热传递测试、机械性能测试等。测试方法必须符合标准规定，并由认可的实验室进行测试。

3. 标识
电弧热防护服装必须标有符合标准要求的标识。标识必须包括：制造商名称、产品型号、保护等级、测试标准、测试结果等信息。标识必须清晰可见，并不易褪色。

IEC 61482-2:2009标准的实施可以有效保护穿着者免受电弧热的伤害。该标准的实施可以提高电力系统带电作业人员的安全性，降低电力系统事故的发生率。
