Glow wire test

Due to the possibility of human mis- application, over-current, or short circuit failures within an appliance wiring system, fire protection requirements were created to evaluate and rate the flammability of material used within an appliance. Glow wire testing is one such . What is glow wire testing ? Its purpose is to protect against the risk of fire from overheated or electrically energised parts which may cause the plastic material to ignite. Simply put, the GWFI is the highest temperature at which three samples of material at the relevant thickness pass the glow - wire test. Knowing the GWFI of a material can help when selecting . A short film showing how glow wire testing is performed. As it is usually the case with other flammability tests also with this test it is not easy to obtain repeatable.

Therefore we designed GLOW WIRE TEST APPARATUS with goal of improved repeatability of test and ease of operation. The BOLD features below are some of advantages that were introduced to reach . The European standard EN 60335-Household and similar electrical appliances - Safety - Part contains safety requirements in Section 30 . The testing of electro-technical products for fire hazard is conducted by simulating as closely as possible actual effects . Burning behavior of compounded thermoplastics is not just a material characteristic. It's also dependent on the shape and wall thickness of the application.

IEC 60695-2-1 ASTM D619 UL746A. This semi-automatic Zwick testing system determines the fire behavior of plastics by means of a glow wire. The tests temperatures are determined by the nature of the product being teste or at the request of the customer.
