ZERMATT灼熱絲測(cè)試儀 ZER-GWT

 Glow Wire Tester 

to test the resistance to fire of insulating parts and assesses the susceptibility of

electrical insulating materials to ignition as a result of exposure to a glowing wire

according to IEC 60695-2-10: Glowing/hot-wire based test methods - Glow-wire

apparatus and common test Procedure ASTM D6194: Standard Test Method for

Glow-Wire Ignition of Materials UL746A: Testing for the resistance to ignition of

polymeric materials.IEC 60950-1, IEC 60335-1, IEC 60884-1, IEC 60238, IEC

60695-2-11, IEC 60695-2-12, IEC 60745-1, IEC 60400, IEC 60730-1, IEC 60598-1, IEC

61050, IEC 60320-1, IEC 61058-1, IEC 60742, IEC 60669-1.

This test method determines the minimum temperature required to ignite a material

by the effect of a glowing heat source, under the specified conditions of test. Inside

the Glow Wire Test Apparatus, a resistance wire (glow-wire) is electrically heated to a specified temperature which is adjustable.The specimen is brought into contact with the glow-wire by a motor-driven sliding carriage. At the end of a prescribed

time the specimen is automatically returned to the starting position.

Observations and measurement are made to evaluate the Glow Wire Flammability

Index (GWFI) and Glow Wire Ignition Temperature (GWIT) presented by the

specimen during exposure to elevated temperatures.

Technical Specification:

•Heating element:Nickel/Chromium Glow-Wire (80:20), 4 mm dia, shaped as

specified in standard

•Temperature sensor: Sheathed Cr/Al thermocouple1.0 mm dia, located in tight fitting pocket hole in glow-wire

•Glow wire application time: 0-999.9s±0.1s

•Ignite Time:0-999.9s±0.1s

• Extinguish Time:0-999.9s±0.1s

•Penetration depth:7mm±0.5mm

•Test speed:18±3mm/s

•Sample loading Test sample moves against glow-wire preloaded to 0.95 ± 0.1N

•Sample carriage: Automatic, motorised movement of test specimen

•Test data: Automatically calculate and display test results

•Safety:Over current protection, over temperature protection

Accessories: wireless control box，wired control box

Optional:Modbus, network card: used for uploading data, and equipped with PC software.
