Horizontal / Vertical Flame Chamber

Product Overview

Description

UL94 Horizontal/Vertical Flame Chamber

Introduction: 

UL94 horizontal and vertical combustion instrument adopts the design idea of full standard satisfaction and takes into account many test standards. It is integrated into a test box.Designed as UL standard flammability test for equipment and appliance component materials, the horizontal and vertical combustion instrument is designed to test numerous end-use test indicators, such as flammability, combustion rate, flame spread, combustion intensity and flame retardancy of products.

Standard: 

1.Horizontal Burning Test : ASTM D 5048 or ISO 10351.

2.Vertical Burning Test : ASTM D 3801, IEC 707, or ISO 1210.

3.500w (125mm) Vertical Burning Test : 5VA or 5VB (ASTM D  4804 or ISO 9773).

4.Thin Material Vertical Burning Test : VTM-0, VTM-1, or VTM-2 (ASTM D 4804 or ISO 9773)

5.Horizontal Burning Foamed Material Test : HBF, HF-1, or HF-2 (ASTM D 4986 or ISO/DIS 9772.3)

6.KS M 3015 : Testing method for thermosetting plastics

7.KS M 3305 : Liquid unsaturated polyester resins for fiber reinforced   plastics

8.KS M 3809 : Thermal insulation material made of rigid urethane foam

9.KS M ISO 9772 : Cellular plastics-Determination of horizontal burning characteristics of small specimens subjected to a small flame

Specification:

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 enables random control and operation by user) enabling adjustment of different height of the specimen and apply lifting flame to specimen;

4, Cable Handy Remote Controller facilitating 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 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 degree), frame, and gas flow meter in addition to 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 user from inhaling noxious gases during test;

11, 2 access ports on the front of the chamber to protect 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 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);
