Introduction

UL 94 - AVH Chamber is capable of measuring the combustion characteristics (residuals, residues) of a test specimen by a burner (H-5025 UL Tirrill Burner) in a combustion chamber with an internal volume of 0.864m3.

The UL 94-AVH of KOFATE is equipped with devices, that can detect the combustion characteristics (residuals, residues) of test specimens in a combustion chamber, and a burner (H-5025 UL Tirrill Burner) with an internal volume of 0.864m3. Also, an air vent is equipped with an internal light and equipped with a ventilation fan which can facilitate the characteristics or internal observation of the test specimen during or after the test and can easily remove the combustion gas.

▣ Apparatus and accessories for varying the shape of flame, angle of burner etc. of various test methods according to the standard (Eg Accessories for testing HBF, HF, ISO 9772)

▣ Three digital timers for simultaneous measurement of time, such as afterglow, and residue

▣ Window 2 Step Locking System for easy sample removal after test

▣ Manual, Semi-Auto, Full Auto type can be selected according to user's requirement 

▣ After flame: The flame continues even after the ignition source is gone.

▣ After flame Time: Time (in seconds) for the duration of the decay under specified conditions.

▣ After glow: Continuous burning after the ignition source and the flame are exhausted,

▣ After glow Time: Time (in seconds) for the remaining time under the specified conditions.

▣ Damaged length (Length of test specimen damage, unit: mm)

▣ Ignited the cotton indicator by drip flaming (Whether Cotton is ignited due to a flame fragment falling off)
