Intelligent Horizontal and Vertical Flame Chamber UL 94

Introduction:   

UL 94 measures the combustion properties (after flame, afterglow) by burner (H-5025 UL tirrill burner) when test sample combusts in chamber's internal volume of 0.864m³ and is installed internal light to observe the specimen's properties and has a ventilating opening with emission fan to remove the combustion gas.

UL 94-AVH has auto specimen moving system for protecting the user from hazardous gas and auto burner moving system for meeting the whole test standards. This auto burner moving system has a goniometer, so it can change the angle of flame to the specimen (0°, 20°, 30°, 45°, 90°).

Control box and remote controller help the user to handle this equipment or check after flame time and afterglow time during testing and are able to adjust the angle.

Feature:   

1.  Auto specimen moving system (The Switch 'MOVE1' in the control box enables random control and operation by user) facilitating automatic movement and removal of sample to the ignition source.

2.  Auto Burner Moving System (The Switch and Remote Controller switch 'MOVE2' in the control box enables random control and operation by user) enabling adjustment of different ignition time and burner angles by standards.

3.  Auto Burner Lifting system (The Switch and Remote Controller switch 'MOVE3' in the control box enable random control and operation by user) enabling the adjustment of different height of the specimen and apply to lift flame to specimen.

4.  Cable Handy Remote Controller facilitating the operation of Timer 1,2 and 3 in the UL 94-AVH Control Box and Auto Burner Moving System.

5.  Double-coated chamber equipped with an exhaust fan to readily discharge combustion gas and internal lighting, whose internal volume is 0.864 m³.

6.  Burner Calibration Kit to measure 20mm flame and 125mm flame under ASTM D 5207 (Copper slug thermocouple and digital thermal indicator for 20mm flame and 125mm flame).

7.  Thermal Indicator and Thermocouple Connector in the control box facilitating calibration of flame calories by the Copper Slug(ASTM D 5207).

8.  Burner complying with ASTM D 5025 equipped with the precision control system including goniometer facilitating adjustment of burner angles(0°, 20°, 30°, 45°, 90°), frame, and gas flow meter in addition to a manometer.

9.  Control Box adjustable at intervals of 30 degrees facilitating time adjustment and operation of the timer by user's location.

10.  Sliding Door made of reinforced glass to observe sample and prevent a user from inhaling noxious gases during the test.

11.  2 access ports on the front of the chamber to protect the user from inhaling noxious gases, adjust the burner and devices in the chamber, and move and fix samples.

12.  Clamp facilitating separation and attachment of the test sample.

13.  Units and accessories to change flame shape and burner angle in diverse test methods by standards(For example, accessories capable of HBF, HF, and ISO 9772 tests).

14.  3 digital timers to measure simultaneously the time of after flame, afterglow and after flame.

Test result: 

1.  After flame: Flame continued even after a firing source disappears   

2.  After flame Time: Time is taken for after flame continued under specified conditions(unit: second)

3.  Afterglow: Glowing combustion continued even after an ignition source and flame disappear   

4.  Afterglow Time: Time is taken for afterglow continued under specified conditions (unit: second)  

5.  Damaged length (Damaged length of test sample, unit: mm)

6.  Ignited the cotton indicator by drip flaming(Ignition of cotton by a dropped flame piece)
