Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard proposed by China State Shipbuilding Corporation. This standard by the National Marine Machinery Standardization Technical Committee Fire Technical Committee (SAC/TC137/SC8) centralized. This standard was drafted by China Shipbuilding Industry Institute of Technology and Economy, Tian-Guang Fire Co., Ltd. The main drafters of this standard. Sun Meng, Huang Ya-tree, Wang Wei, Li Xinzhou. Fire protection test method for marine products

1 Scope

This standard specifies the test requirements, procedures and methods for testing the ignition protection of marine products using a mixture of propane and air. This standard applies to marine products ignition protection test and acceptance, marine explosion-proof equipment, intrinsically safe equipment and in hydrogen and air Parts used in the mixed gas can refer to use.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 Combustible hydrocarbon gas mixture flammablehydrocarbonmixture Ignition in any way between the lower explosive limit (LEL) and the upper explosive limit (UEL) can cause an explosive mixture of propane and air. 2.2 Sealed hermeticalysealed The gap is sealed by welding, brazing, melting glass, or the like to prevent the air pressure from changing when the air pressure or ambient temperature changes or both When the time change of air or gas into or overflow of a process. 2.3 Ignition protection ignitionprotected By building a device or component, to achieve the following purposes. a) When the combustible hydrocarbon mixture inside the device is normally ignited by an arc, a spark or a heat source, the combustible hydrocarbon at the periphery of the device Gas mixture will not be ignited; b) the arc, spark or heat source does not have sufficient electrical or thermal energy to ignite the combustible hydrocarbon mixture; or c) Seal the ignition source from the surrounding mixture. Note. The ignition sources include the following three main types. a) Any electrical contact, commutator and assembly friction or friction of the slip ring may result in arcing with ignition energy; b) A resistor or other element may ignite a combustible hydrocarbon gas mixture at temperatures high enough; c) Mars, which produces sufficient energy when the two materials collide with each other, may ignite the combustible hydrocarbon mixture.

3 test requirements

The test preparation and test requirements for various electrical installations are as follows. a) For electrical installations that have an electrical connection, or other arc ignition source with sufficient energy to ignite a combustible hydrocarbon gas mixture, The test shall be prepared in accordance with the provisions of Chapters 6 to 8 and in accordance with the provisions of Chapter 9 for the ignition of the internal air mixture test; b) For electrical installations with heating elements (eg resistors), the test shall be prepared in accordance with the provisions of Chapters 6 to 8 and in accordance with paragraph 10 provisions of the test; c) Electrical devices classified as ignition protection for igniting combustible hydrocarbon gas mixtures that do not emit sufficient electrical energy, shall be tested Use the test equipment described in Chapter 5, Energy Tester, and prepare and test in accordance with the provisions of Chapter 11; d) The potential ignition sources for sealing are classified as electrical components for ignition protection and shall comply with the requirements of 7.1 and 7.2 and shall comply with the requirements of 12 Chapter ignition source seal in the provisions of the test; ......
