Frequently Asked Questions

Q1: What is this equipment used for?

A1: This tester evaluates the flammability of plastic materials used in electrical devices and appliances, classifying them per UL94 ratings such as HB, V-0, V-1, V-2, 5VA, and 5VB to help manufacturers meet product safety requirements.

Q2: What standards does it comply with?

A2: The equipment complies with UL 94-2006, IEC 60695-11-3, IEC 60695-11-4, IEC 60695-11-10, and IEC 60695-11-20, covering both 50W and 500W flame test methods.

Q3: What materials can be tested?

A3: Plastic materials used in parts for devices and appliances, including rigid plastics, thin materials (VTM), and foamed materials (HBF/HF-1/HF-2).

Q4: What is the difference between 50W and 500W testing?

A4: The 50W configuration is used for HB and V-classification tests (V-0, V-1, V-2), while the 500W configuration is used for 5V-classification tests (5VA, 5VB) which require higher flame energy.

Q5: What gas does this equipment require?

A5: The tester requires methane gas with a minimum purity of 98%. Gas flow rates are 965 ± 32 ml/min for 500W tests and 105 ± 10 ml/min for 50W tests.

Q6: Does the test result reflect real-world fire hazards?

A6: No. The test measures relative flammability performance under controlled laboratory conditions and does not represent actual fire hazards that may occur in real-life scenarios.

Q7: What are the chamber dimensions and construction?

A7: The chamber is constructed from stainless steel with a black interior and a volume greater than 0.5m³. It features a large sliding window for easy viewing during tests.

Q8: Is the timer adjustable?

A8: Yes, the digital timer is adjustable from 0 to 999.9 seconds with an accuracy of ±0.1s, allowing flexibility for various test procedures.
