Plastic Flammability Tester UL 94

The Plastic Flammability Tester is a laboratory instrument designed according to the UL 94 standard to evaluate the flammability of plastic materials and components. It provides accurate and repeatable testing of how plastics react to fire under controlled conditions, including ignition, burn rate, flame spread, intensity, and combustion by-products. This instrument is essential for assessing fire safety, material compliance, and certification in industries such as electronics, appliances, automotive, and building materials. The tester supports multiple test types, including horizontal, vertical, foam, and non-rigid material burning evaluations.
