小型船舶 电气装置 防止周围可燃气体点燃的保护

[中文适用范围]： 本文件规定了在正常操作条件下，用于小型船只的电气设备的设计测试方法和要求，以确保这些设备在操作过程中不会点燃周围的可燃气体环境。本文件不适用于以下情况的防爆措施：— 可在氢气与空气混合物中运行的设备或部件；— 存在功能故障的设备；— 由外部因素（如静电、雷电或其他与被测设备无关的因素）引起的点火机制。 [外文原描述]： This document specifies test methods and requirements for the design of electrical devices, when under normal operating conditions, on small craft so that they can be operated without igniting a surrounding flammable gas atmosphere. This document does not apply to ignition protection procedures for: — devices or components that can operate in hydrogen and air mixtures; — devices with dysfunctional issues; — mechanisms of ignition from external sources, such as static electricity, lightning or other factors not related to the equipment under test.
