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-wiring system(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。南京睿督已协助国内线缆厂家成功取得AS/NZS3013 WS52W证书,具体内容请咨询南京睿督工程师,025-8658 3475。
AS/NZS 3013 is a classification system which defines the performance of a Wiring System (WS). The classification
system prefix is 'WS' followed by two numerals and cables are subected to fire at 1050°C from 15mins to 120mins meawhile Impact Test
from 2.5J to 5000J and Cutting Test from 0.3kN to 5.0kN about the level of protection range from light duty to extremely duty.

AS/NZS 3013 电气装置—配线系统元件的防火和机械性能分类,南京睿督提供澳洲NATA资质的AS/NZS 3013 WS52W电缆耐火冲击机械性能检测及等级证书。
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)
