IEC60695-2-10 Materials Glowing Wire Ignitability Test Machine

Overview:

The glow wire test is to test the stability of electronic and electrical products during operation. The glow wire itself is actually a resistance wire loop with a fixed specification. During the test, it must be heated to a specified temperature by electricity, so that the tip of the glow wire contacts the sample for a standard time, and then observe and measure its state. The test range depends on the specific Test procedure.

Standards:

Scope of application:

The glow wire testing machine is mainly suitable for electricians, electronic products, household appliances and their components and parts for fire hazard tests, and simulates the thermal stress caused by heat sources or ignition sources such as hot components or overload resistance in a short time. Suitable for solid electrical insulating materials or other solid combustible materials.
