Description

Fire Resistance with Mechanical Shock and Water Spray Test Equipment

Introduction

Hard to catch fire and having the ability to prevent or delay the spread of flame ,wire and cable can generally refers to IEC******3 test.This wire and cable fire-resistant impact test equipment is designed according to IEC *******2 and BS***7 ****3 standard. It is used to test if the circuit will maintain integrity under flame temperature is not lower than **0ºC, and the case of a certain impact vibration. You can test cables A, B, C, D retardant properties.

Standards
• IEC ****1 part *2 test wires and cables under fire conditions - at least at **0 ºC shocks combustion circuit integrity -
• IEC ****1 part *1 procedures and requirements for fire with shock - rated voltage up to 0.6 / 1.0 KV cables
• IEC ****1 part 1 specifies the test method for cables which are required to maintain circuit integrity when subject to fire and mechanical shock under specified conditions.
• (Option)BS********3
-The impact is applied for the fire, the flame temperature is not lower than **0ËšC, the rated voltage is greater than or equal to 0.6 / 1kV cable, the overall diameter of more than *0 mm
• IEC ******2
-The impact is applied for the fire, the flame temperature is not lower than **0ËšC, the rated voltage is greater than or equal to 0.6 / 1kV cable, the overall diameter of not more than *0 mm;
