澳洲AS/NZS3013 WS52W等级及要求
澳洲AS/NZS3013对耐火电缆具体耐火等级进行详细的划分。例如AS/NZS3013代号:WS52W。WS-wiringsystem(接线系统),第二个数字代表着耐火时间:5代表120分钟耐火试验。第三个数字代表线缆系统在受到冲击与剪切时机械保护程。第四个字母W的意思是water(水),也就是要对电缆进行喷淋试验来验证线路的完整性。喷水试验是在燃烧试验之后进行的。喷水时间为180秒,燃烧条件为1050℃,120分钟。公

澳洲AS/NZS3013耐火电缆–适用范围
本标准规定了配线系统元件的分类。根据配线系统的能力分为:
(a)在着火条件下保持电路完整性规定的时间;
(b)保持电路完整性,以防止出现指定严重程度的机械损坏。
例如,WS52W 额定电缆将具有以下特性;
·WS – 适合包含在布线系统中
·5 - 在火灾条件下具有 120 分钟(两小时)的电气性能(电路完整性)
·2 - 在正常使用期间提供中等水平的冲击损坏保护
·W – 暴露于高架洒水喷头的水后具有电气性能(电路完整性)
