Fire Resistance Test Standards For Cable Protection Systems

In the event of fire performance to internal and external fire, it has been established that an enclosure fabricated from fire resistant boards is one of the best solutions. Such systems have been tested successfully with ducts constructed from fire protective boards such as PROMATECT®-H, PROMATECT®-L or PROMATECT®-L500. These well established board systems are the only systems which currently fulfil all performance requirements, especially to the DIN4102 standards.

fires cause the following problems
• Prevent the propagation of fire from one building compartment to another,
• Assist in maintaining escape routes,
• Ensure the continuing operation of other services within a common service,
• Reduce damage to localised area,
• Contain smoke and toxic fumes from burning cables.
• Ensure cable maintain their function when exposed to a fully developed fire.

Reliability Of Fire Resistant Cables

Typical uses of cables to, in and from Electrical and Mechanical enclosures include fire alarms, emergency lighting, addressable alarm systems, CCTV systems, emergency power supplies and smoke and fire shutters. These cables are normally designed to meet the standards for Fire Detection and Alarm Systems in BS5839: Part 1 and Codes of Practice for Emergency Lighting in BS5266: Part 1. Most fire resistant cables have been subjected to tests in accordance with BS6387: 1994 “Specification for performance requirements for cables required to maintain circuit integrity under fire conditions” and/or IEC60331-11, 21, 23 & 25 “Test for electric cables under fire conditions – circuit integrity”.

The Australian/New Zealand standard AS/NZS 3013 “Electrical installations – Classification of the fire and mechanical performance of wiring systems” describes the level of protection of a wiring system against fire and/or accidental mechanical damage. The tests methods described within this standard call for wiring systems to maintain circuit integrity when subjected to fire test, mechanical damage tests, and fire and water tests. The resistance to fire test is to determine the ability of a wiring system to maintain circuit integrity under fire conditions for a specified period of time of up to 120 minutes. The wiring system shall be tested in a horizontal furnace complying with AS1530: Part 4, which also employs the ISO834 heating conditions. Mechanical damage tests are to determine the degree of mechanical impact and cutting load to which the wiring system can be subjected without losing its circuit integrity. The tests are carried out separately from the fire test.
