When installing essential electrical systems such as emergency lighting or fire safety controls, great emphasis is placed upon the fire survivability of the critical components such as fire dampers, actuators and cables that are contained in the area.

Often the specification of the junction boxes and enclosures is neglected with respect to fire resistance and survival. On the basis that any system is only as good as the weakest part, it is important that attention is paid to the junction boxes being utilised for essential systems.

Abtech ensure the fire survival of junction boxes using both the SX (stainless steel enclosure) and BPG (GRP enclosure) ranges - see fire rated enclosures for further information about junction boxes capaable of resisting and surviving fire according to PH120 pre-assmembled with ceramic terminals.

Abtech SX and BPG electrical enclosures and junction boxes when fitted with ceramic terminals are suitable for use in areas designated to require fire resistant cables according to IEC331, BS6387 C (fire alone), BS6387 Z (impact test) and BS6387 W (fire with water test).

Fire Rated Enclosures Standards Explained

IEC 331 Test

The IEC 331 test is used for verifying the resistance to fire of electrical cables where circuit integrity under fire conditions must be maintained. 

The standards set under the IEC 331 test state that the cable must be exposed to a flame with a minimum temperature of 750°C for at least 90 minutes. 

• 'C' - Fire alone
• 'W' - Fire and water
• 'Z' - Fire with mechanical shock

The BS6387 specification recommends each category of the test is carried out at different temperatures for various lengths of time.

The category 'C' test with fire alone is conducted at 950ºC for 180 minutes, category 'W' tests with fire and water are carried out at 650ºC for 30 minutes and category 'Z' tests with fire and mechanical shock are carried out at 950ºC for 15 minutes.
