The UL test serves as a preliminary indication of a plastics material acceptability for use as part of a device or appliance with respect to its flammability.
UL 94: Test for Flammability of Plastic Materials for Parts in Devices and Appliances
This test uses specimen which is held at one end in the vertical or Horizontal position . A burner flame is applied to the free end of the specimen for two intervals separated by the time it takes for flaming combustion to cease after the first application. Two sets of 5 specimens are tested. The following are recorded for each specimen:
The instrument is designed to conforms to various international standards
Horizontal Burning Test : HB (ASTM D 635, D 4804, IEC 707, or ISO 1210)
20mm Vertical Burning Test: V-0, V-1, or V-2 (ASTM D 3801, IEC 707, or ISo 1210)
500w (125mm) Vertical Burning: 5VA or 5VB (ASTM D 5048 or ISO 10351)
The Instrument consist of the following
A Double Walled Chamber for sample burning with front glass door
A Burner settable at anywhere between 0- 90o angle and precise gas control system including gas regulator
Manual Burner Moving system
Sample Holding System (adjustable both vertically and horizontally)
Digital Timer for flame application (can be preset for 1 to 99 sec)
Digital timer for flame observation after flame is removed.
Digit timer for Glow observation after the flame is extinguished
Exhaust Fan / Light in the chamber
As per UL 94
Inner Chamber Stainless Steel 1m x 1m x 1m (LBH), Volume 1 m3
Burner 100 mm length 9.5 mm ID
Burner Movement through a motor driven worm
Manual Movement to adjust the burner position with respect to sample
Flame Application Time : Pre settable from 1 to 99 Seconds
Flame Away time : Pre Settable from form 1 to 99 Seconds
Cycles : Pres Settable from 1 to 9
Adjust the burner position with respect to sample using manual burner movement.
Manually Ignite the burner
Set the test parameters
Start the process. Press the Forward switch to take the burner to the sample. The Flame Application timer will start.
After Flame application time, there will another beep indicating the operator to move away the burner.
The Burner can be moved again to the sample for multiple burning.
After required no of cycles, the burner is automatically shut off with a beep.
The Timer for After Flame is switched On automatically. After user Hold this timer, Glow timer is switched On.
