FAQ's of UL94 Plastics Horizontal/Vertical Combustion Tester:

Q: How is the UL94 Plastics Combustion Tester operated?

A: The tester is operated using a touchscreen PLC control system, allowing users to set flame application time, test mode (horizontal/vertical), and test speed. The process is largely automatic, with options for manual data logging or exporting via USB.

Q: What are the main benefits of using this combustion tester?

A: This equipment delivers accurate, repeatable flame resistance measurements for plastics, improves quality control, ensures compliance with UL94, and enhances operator safety through automated controls, safety interlocks, and an observation window.

Q: When should the flame height be adjusted during testing?

A: Flame height should be set to the standard requirement of 20 mm 2 mm before beginning each test run, ensuring accordance with UL94 methodology and consistent results.

Q: Where is this tester typically used?

A: It is commonly found in plastic test laboratories, quality control departments, and manufacturing facilities concerned with the flame retardancy of plastic components.

Q: What is the process for conducting a UL94 flame test?

A: After setting the specimen in the chamber, the user selects horizontal or vertical testing, adjusts relevant parameters, and initiates the test. The machine automatically ignites the flame, applies it for the preset time, and measures afterflame/afterglow using auto timing.

Q: How is data from each test recorded or exported?

A: Data can be manually logged during each test or exported conveniently via the USB interface for digital record keeping and traceability.

Q: What types of specimens can be tested with this equipment?

A: The tester accommodates one specimen per run, sized 125 mm 13 mm for both horizontal and vertical test modes, conforming to UL94 requirements.
