Description
As per IEC 60695 – 2 – 10 : 2021 (Glowing/hot-wire based test methods – Glow-wire apparatus and common test procedure), parts of solid insulating materials are ignited by glowing wires. A nickel/chromium wire is heated to 960°C and the insulating material is pushed against it with a force of 1 Newton. It is checked that the insulating material does not attain a certain temperature or catches fire so as to prevent fire hazard in their vicinity. For complete description, please refer IEC 60695 – 2 – 10 : 2021, even if you have product specific standards such as IEC 60898 for Miniature Circuit Breakers (MCB), IEC 60335 for Safety of Electrical Appliances or IEC 60947 for Switchgears and so on. If your product is to be tested for conformity assessment, please also refer ASTM D 6194 – 3 (Standard Test Method for Glow-wire ignition of materials).
