ISO 3582 and UL94 Foam Vertical Horizontal Burning Flammability
Scope of application:
Applicable to evaluate the relative burning performance of small
samples of foam (foam rubber) under laboratory conditions.
Compliance with the standards: The HBF, HF-1, and HF-2 test
standards comply with GB8332, GB8333, ISO 3582, and UL94.
The main parameters:
1. Test chamber size: length 600mm, width 300mm, height 760mm
2. Timer: 0 ~ 99.99S arbitrary settings.
3. Combustion gas: 98% methane gas or 98% propane gas (Generally,
liquefied petroleum gas can be used instead)
4. Horizontal combustion test: see Figure 2
