Glow wire testing machine

一. The product introduction:

    This Glow wire testing machine is mainly used for electrical and electronic parts or parts under fault or overload conditions, may reach excessive temperatures or ignite parts near them, and the glow wire test simulates a heat source or an ignition source such as a hot component or an overload resistor. The thermal stress caused by time is used to evaluate the fire hazard by analog technology. It is applicable to plastic and non-metal insulating parts such as switch housings and relay sockets for electrical and electronic products, components and household appliances.

二. The reference standard of Glow wire testing machine:

    IEC60695 - 2 - 10 / 11 / 12 / 13 <Test method for ignition hazard of electronic and electrical products

    IEC60884-1-2002 "Plug and socket for household and similar purposes"

    GB2099.1-2008 "Plug and socket for household and similar purposes"

    IEC60335-1 "Safety of Household Appliances and Similar Appliances"

    GB4706.1-2005 "Safety of household and similar electrical appliances"

    VDE0620-2010 "General requirements for plugs and sockets for household and similar purposes"
