UL94 Horizontal & Vertical Flammability Tester - TNG1067

The TNG1067 UL94 Horizontal & Vertical Flammability Tester is designed to evaluate the flammability characteristics of various materials according to specified standards. The instrument operates by exposing a sample to a controlled flame source and measuring the material's response, such as burning rate, flame spread, and self-extinguishing properties. It is suitable for testing plastics, rubber, film, textiles, and other non-metallic materials. The TNG1067 supports a range of international standards, including UL94 HB, UL94 V0, UL94 V1, UL94 V2, UL94 5VA, UL94 5VB, UL94 VTM-0, UL94 VTM-1, UL94 VTM-2, UL94 HF-1, UL94 HF-2, ISO 9772, ISO 9773, ASTM D635, ASTM D3801, ASTM D4804, ASTM D4986, GB/T 2408, and GB/T 8332. The tester is equipped to perform both horizontal and vertical burning tests, as well as the Radiant Panel Flame Spread Test. It is powered by 220/110 V, 50/60 Hz and is suitable for use in laboratories and quality control environments. The instrument is ideal for assessing flame resistance in materials used in electronics, electrical devices, and industrial applications.

The Flammability Test Chamber has X, Y, and Z axes. They can be moved freely. This makes it easy for customers to position the specimen and track the flame during combustion.

It has an ASTM D 5025-compliant burner.

You can adjust its angle simply to 0°, 20°, or 45°. This Flammability Testing Equipment has a precise gas control system. This system includes a gas flow meter, pressure regulator, and pressure gauge.

The Flammability Tester has microcomputer control.

It has a high level of automation. It records test time and shows test results. It times, ignites, and alarms automatically. It also returns the Bunsen burner after the flame ends. The Flammability Test Chamber makes it easy to perform horizontal and vertical flammability and burning tests.

Large space, easy operation.

The flammability chamber has a large internal volume of 0.9 square meters. Also, the flame test chamber has internal lighting. It also has an exhaust fan to vent combustion products.

The door and window are well-designed. They are made of tempered safety glass, which lets the specimen be seen during the UL 94 test. This Flammability Tester is fully adjustable for horizontal and vertical specimen holders. So It is also called horizontal flammability and vertical flammability tester.

Electronics: Ideal for testing flame resistance in insulated enclosures, switch panels, circuit boards, and insulating materials of electronic devices.

Plastics: Used to assess flammability in plastic and non-metallic materials under 50W flame in both horizontal and vertical orientations.

Other Materials: Applicable to lighting fixtures, electrical devices, motors, tools, and components like engineering plastics and insulating materials, ensuring compliance with fire safety standards.

UL 94 testing, is a common test in flammability testing labs and is used to test the UL flammability rating of plastics. The UL94 test chamber has two test modes, which respectively are horizontal flammability test and vertical flammability test. Detailed UL94 test methods are as follows. FLAMMABILITY UL 94 V (50 W, 20 mm Vertical) Objectives This vertical flammability test is to determine the UL flammability rating v0 and flammability rating v1 and v2. The test evaluation includes the burning time, afterglow time, and the dripping of the combustion test sample. Flammability Testing Equipment UL94 Flammability test chamber Pretreatment The relative humidity is 2 days/ 23℃/ 50%, and the hot air oven is 7 days/ 70℃. The flame height should be controlled to 20mm. The flame application time is 2× When the first burning time is over, the second flame application time begins.
