Electric Wire and Optical Cable Heat Release TesterThe ZONSKY Electric Wire and Optical Cable Heat Release Tester is a specialized instrument designed to assess the fire performance of electric wires and optical cables by measuring their heat release rate during combustion. This apparatus subjects cable samples to controlled thermal conditions, recording critical parameters such as peak heat release, total heat emission, and time to ignition.Talk To Our Team It is particularly suitable for evaluating the combustion performance of cables and optical cables used in construction projects. Compliance- EU Standard EN 50575:2014 – Power, control, and communication cables for general applications in construction works subject to reaction to fire requirements.
- EU Standard EN50399:2011 – Common test methods for cables under fire conditions – Heat release and smoke production measurement on cables during flame spread test.
- Chinese Ministry of Public Security Standard GA/T 716-2007 – Test method for electric or optical cables under fire conditions—Flame spread, heat release, and smoke production measurement during test.
