IEC60695-2-13 Glow Wire Tester With Ф4mm ± 0.04mm Glowing Filament
The Standard describes a glow-wire ignition temperature test method for materials. It is intended to be used to measure, describe, and rank the properties of materials in response to heat caused by contact with an electrically heated wire under controlled laboratory conditions.
This may be useful for the evaluation of materials for use in products that may be exposed to excess thermal stress such as a fault current flowing through a wire, overloading of components, and/or bad connections. It is not intended to be used to solely describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test can be used as elements of a fire hazard assessment which takes into
account all of the factors which are pertinent to a particular end use.
Standard:IEC60695-2-10, IEC60695-2-13 and UL746A.
Application:This device simulates the thermal stress test of glowing component or heat source like overload resistance or ignition source which is caused in a short time. It is suitable for electric and electronic products, household appliances and other material to do fire hazard testing. It is also used in the No flame ignition source fire test to test initiation temperature and flammability index of related glowing filament.
Test sample:Electrical equipment and its components and parts, solid electrical insulating materials and other solid combustible materials. Flammability Testing Equipment
Feature: Test principle: the glowing filament whose material and shape is required(Ni77/Cr20) is heated to the testing temperature of 550 ℃ ~ 960 ℃ for 1 min by using the glow wire tester with large current. Then using required pressure (0.95N) vertically burns the test sample for 30s. By observing whether the test sample and bedding object ignite or the burning time, the users can judge the ignition danger of electric and electronic products. It is used for the ignition test, ignition temperature (GWIT) test, flammability test and flammability index (GWFI) test of solid insulating material and other solid combustible material.
