SCR Elektroniks Glow Wire Test Apparatus GWT A2

GLOW WIRE TESTER (also known as Glow Wire Test Apparatus) is designed to carry out fire hazard testing as specified in IEC 60695-2-10 2000-10. Flammability test is to check the ‘Resistance to Fire’ of electrical insulators that touch directly conducting parts & also parts of insulators. This test is also referred in many other standards such as IS 11000, IS 3854 : 1997 / IS 1293 :1988 / IS 371 :1999 & IS 11000 Pt 2 Sec 1, IEC 60335, IEC 884/94, IEC 60598, IEC 61058, BS 6458, BS EN 60695–2-10,11,12, etc.
