Wire Fire Resistance with Mechanical Shock Test Apparatus 

Introduction

Wires and cables that are hard to catch on fire and have the ability to prevent or delay the spread of fire are usually referred to IEC60332-3.This test apparatus is degsigned and produced according to BS6387-2013 and GB/T 19216 to the latest standards requirements. Because two different tests can be carried out on one electrical control box, this apparatus can save much cost for customers.


Standards:
• IEC 60331 part 12:Tests for electric cables under fire conditions - Circuit integrity - Part12: Apparatus - Fire with shock at a temperature of at least 830 C
• IEC 60331 part 31:Procedures and requirements for fire with shock - Cables of rated voltage up to and including0,6/1 kV

• IEC 60331 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)BS6378:2013 Performance requirements for cables required to maintain circuit integrity under fire conditions
