标准摘要
[中文适用范围]： IEC 60331 的这一部分规定了用于测试在遭受火灾和机械冲击时保持电路完整性所需的电缆的测试设备，其中测试条件基于具有与标称 850℃温度相对应的受控热输出的火焰。 ？它适用于测试外径大于 20 毫米的电缆。它还在附件 A 中提供@用于测试的燃烧器和控制系统的验证方法。 [外文原描述]： Specifies the test apparatus to be used for testing cables required to maintain circuit integrity when subject to fire and mechanical shock where the test condition is based upon a flame with a controlled heat output corresponding to a temperature of a nominal 850 °C. It is intended for use when testing cables of greater than 20 mm overall diameter. It also provides, in annex A, the method of verification of the burner and control system used for the test. Has the status of a group safety publication in accordance with IEC Guide 104.
