Description

This instrument is designed to testing cables for resistance to fire of cable required to maintain circuit integrity under fire conditions. The instrument is applicable to cables of rated voltage not exceeding 600/1000 V and of overall diameter less than or equal to 20mm (as per BS 6387) and diameter exceeding 20mm (as per BS 7846).

The instrument is designed

Test cables under three protocols as per BS 6387:2013, BS 7846:2009 and BS 8491:2008 for

Protocol C: subject the cable under test to a flame via direct impingement corresponding to a temperature attach of 950oC

Protocol W: subject the cable under test to a flame via direct impingement corresponding to a temperature attach of 650oC with direct application of water simulating a sprinkler system.

Protocol Z: subject the cable under test to a flame via direct impingement corresponding to a temperature attach of 950oC with indirect application of mechanical shock.

Category F2: Resistance to Fire, Resistance to fire with water, resistance to Fire with Mechanical Shock assessed separately as per BS 6387

Category F30: Resistance to Fire with direct mechanical impact and water assessed in combination when tested as per BS 8491:2008 for 30 min

Category F60: Resistance to Fire with direct mechanical impact and water assessed in combination when tested as per BS 8491:2008 for 60 min.

Category F120: Resistance to Fire with direct mechanical impact and water assessed in combination when tested as per BS 8491:2008 for 120 min.

The instrument can be bought as complete unit or can be bought as piece meal as per customer requirement.

The Instrument Consist of

 

Burner (for Protocol C) : Tube Type LPG / propane  gas burner. Overall length of the nozzle is  610mm.
Burner (for Protocol W and Z ) : Ribbon Type LPG / propane  gas burner. Overall length of the nozzle is  500mm.
Burner Control: With double variable flow meters (Roto meter). Roto meters range is : 95+/- 5 LPM, gas flow range is : 10 +/- 0.5 LPM. Two Pressure Gauges of 0-60psi will be provided to control the input pressure for Air and Gas.
Flame Temperature: Adjustable up to 950+/- 50oC using the flow control.
Temperature Calibration : Two MI thermocouples will be provided to calibrate the flame temperature (can be fitted in each jig)
Three Phase Transformer  (up to 1 KV) with individual tripping system for all the three phases, Neutral and Earth.
Test Jigs for Test with Fire only : Sample stand complete with SS rings and sample holder for Test with Fire only as per BS 6387:2013
Test Jigs for Test with Fire with Mechincal Shock : Sample stand complete hammer to produce mechanical shock during test for Test with Fire with mechanical shock as per BS 6387:2013
Test Jigs for Test with Fire with water sprinkler : Sample stand complete water sprinkler to sprinkle water on the samle during fire test as per BS 6387:2013
Test Jig for Test with Direct Machanical Shock in combination of water jet as per BS 8491:2008
Load bank to indicate the line continuity for three phases, Neutral and Earth
