Wire Fire Resistance+ Mechanical Shock Testing Machine，IEC 60331
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 the wires and cables that can be tested by IEC60332-3.Thistester is degsigned and produced accordance with the BS6387-2013 and GB/T 19216 to the latest standards requirements. Because two kinds of tests can be carried out on the one electrical control box, this tester could savings much cost for customers.
All kinds of experiments can be freely selected on the touch screen.
Standards:
• IEC 60331 part 12
• IEC 60331 part 31• IEC 60331-1
• (Option)BS6378:2013 Performance requirements for cables required to maintain circuit integrity under fire conditions

10. PLC and touch screen control system, and automatically record store test data.
11. The circuit current fuse is 2A;
12. Samples impose power AV 100V~1000V adjustable;
13. The test time can be set freely, the standard recommending time is 90min,
14. 27m ³ combustor is optional.
Fire Resistance：
1. The burner nozzle length 500mm, width 15mm, there are three holes on the nozzle opening troubleshooting, pore radius of 1.32 mm pitch is 3.2 mm. Equipped with Venturi mixer;
2. Installation and testing of the cable ladder fastened to the supporting steel chassis; the testing process can be adjusted on both sides of the vertical component testing ladder depending on cable size requirements (test stand length: 1200mm, height: 60mm, total weight: 18 ± 1kg)
Metal ring inside diameter of about: 150 mm.
3. With a temperature measuring device (diameter less than 2mm K-type thermocouple, from the flame ports 75mm).
The front burner torch from the bottom of the box less than 200MM, 500MM and from the tank wall at least
According to the test grade, the flame temperature is adjustable: 600 ~ 1000 ° (A grade 650 °, B grade 750 °, C, D grade 950 °)
4. The horizontal distance between the center of the burner test cable 40-60MM, the vertical axis from the longitudinal axis of the specimen cable burner 100-120MM
5. Provide standards of five inner diameter of about 150 mm from metal rings, metal ring distance can be freely adjusted to facilitate sample fixed hold.
6. Stainless steel sample tray, load 30kg
