BS 7917:1999标准规定了弹性体绝缘防火(有限电路完整性)电缆用于船舶和移动和固定海上装置的要求和试验方法。该标准适用于额定电压不超过600/1000V的电缆,用于固定布线和控制电缆。

该标准要求电缆必须具有防火性能,能够在火灾情况下保持电路完整性,以确保电缆在火灾情况下能够继续传输电信号或电能。电缆的绝缘材料必须是弹性体,以确保电缆在高温下仍然具有良好的绝缘性能。此外,电缆必须具有良好的耐磨性和耐腐蚀性,以适应船舶和海上装置的恶劣环境。

该标准还规定了电缆的试验方法,包括电缆的外观检查、绝缘电阻测试、电缆的热稳定性测试、电缆的热冲击测试、电缆的机械强度测试、电缆的耐火测试等。这些试验方法可以确保电缆符合标准要求,并能够在火灾情况下保持电路完整性。

总之,BS 7917:1999标准规定了弹性体绝缘防火(有限电路完整性)电缆用于船舶和移动和固定海上装置的要求和试验方法,确保电缆在火灾情况下能够继续传输电信号或电能,以保障人员和设备的安全。
