Glow wire apparatus is the commonly used equipment for testing solid insulating material for fire hazard testing. This test apparatus is covered in IEC 60695-2-10 and commonly referred for various devices in many standards such as IEC 60335, IEC 60695-2-11, IEC 60695-2-12, IEC 60598-1, IEC 60947, IEC 60898, IEC 61008-1, IEC 60669-1, IEC 60884-1, IEC 60950-1 / IS 13252, IEC 60238, IEC 60745-1, IEC 60400, IEC 60730-1, IEC 61050, IEC 60320-1, IEC 61058-1, ASTM D 6194-03 and UL 60745-1.
As per IEC 60695-2-10 (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).
Designed to carry out Fire Hazard Testing as specified in IEC60695-2-10:2021.
Glow wire test apparatus GWT -A4 ( Automatic Operation) for testing insulating material as per IEC 60695-2-10:2021, IEC 60335, ASTM D 6194-03 & other standards.
Glow Wire Test Apparatus can be customised as PC based & Non PC based.
Under PC based Model LabVIEW based software (TestWare®) is used to control sequence of operation along with SCR make ethernet based DAQ interface system. Setting and control of Heating, Control of current will be through PC. Speed of carriage of specimen will be adjustable as per standard through PC. Test Time, Application time will be settable. PC will record Ignition time & Extinguish time with manual input from operator. Results will be stored on PC as per test samples & Date.
The product tests the susceptibility of the insulation material against piercing metallic parts when subjected to fire. The insulation sample under test may be examined later on and be subjected to more tests
The test is carried out to asses the flammability characteristics of a Product body, typically made up of thermoplasts and thermosets. The glow wire tester is an important tool not just to assess the quality of the Product, but also to continuously check the incoming components related to the Product body for their flammability characteristics. Material moulds manufacturers can use this product to ascertain the quality of the Material under test
