Based on the current wide application of foam in construction, packaging, automotive and other fields, its combustion performance testing has become a core aspect of safety compliance. The following is a comprehensive explanation of the foam combustion tester, combined with the latest industry standards and technological advances:
I. Core functions and test significance of the equipment
Function definition
Foam combustion tester is a special equipment used to evaluate the combustion behavior of foam materials (e.g. polyurethane, EPS, XPS, etc.) under open flame or high temperature, and the main test indexes include:
Burning rate (flame spreading speed, self-extinguishing time)
Smoke generation (optical density, smoke toxic gas concentration)
Drops ignitability (whether the molten material ignites the cotton pad underneath)
Industry Values
Safety compliance: meet the mandatory requirements of building fire codes (e.g., GB 8624-2022, Classification of Combustion Performance of Building Materials), and flame retardant standards for automotive interior materials (GB 8410-2023).
R&D optimization: guide enterprises to improve formulations (e.g., add flame retardants, nano-composite materials) to reduce fire risks.
Operation specification and risk avoidance
Typical test procedure (take UL94 vertical burning as an example)
Pre-treatment: Samples are stored at 23C/50% humidity for 48 hours.
Flame application: Use 20mm blue Bunsen flame (methane purity 98%) to burn the lower end of the sample for 10 seconds.
Determination of results: If the burning time is 10 seconds and there are no drips to ignite the cotton pads, it is determined to be class V-0 [[1][6]].
Common Risks and Countermeasures
Sources of error: Fluctuation of environmental humidity (need to be equipped with constant temperature and humidity test chamber linkage control).
Safety protection: Operators need to wear gas masks (to prevent HCN inhalation), automatic fire extinguishing system for combustion chamber trigger temperature set to 300C [[5]].
