EN 12416-3 - Fixed firefighting systems - Powder systems - Part 3 - Requirements and test methods for dry chemical powder in marine and offshore

Scope

This European Standard specifies requirements and test methods for gas fires and laboratory ageing for the performance verification of dry chemical powder, which will be used in marine and offshore required by MSC/Circ. 1315 Part 8. The following tests will be covered:

- jet fires

- pool fires

- laboratory ageing of the dry powder

This standard covers test procedures for dry chemical powder in marine and offshore installations. The performance of the dry powder fire extinguishing systems itself must be tested acc. to MSC/Circ. 1315. It does not cover any component tests, for example pressure regulators, gauges, expellant gas container assemblies etc. 

Purpose

Note: in case the WI is based on documents from other organizations than ISO/IEC, please specify it here

This standard covers test procedures for dry chemical powder in marine and offshore installations. The performance of the dry powder fire extinguishing systems itself must be tested acc. to MSC/Circ. 1315.

The tests described in this standard are designed to give some indication of the suitability of fixed dry powder extinguishing systems for the LNG bulk carrying industry.

The fire scenarios described in this document have been agreed upon by representatives from fixed dry powder extinguishing systems manufacturers, carriers, classification and laboratories. They are regarded as being generically adequate for testing the performance of extinguishment technology without being necessarily similar to fires that might occur in the real world.

A successful outcome of this test does not guarantee safety or the suitability of any particular technology, but may be used as an element to a fire risk assessment in the LNG transportation industries or owners how uses LNG as fuel.
