The UL94 Horizontal and Vertical Burning Tester is a precision
flammability testing instrument designed for evaluating the fire
resistance of materials such as plastics, textiles, and
electronics, in compliance with international standards like UL94,
IEC 60695, and GB/T 2408. This advanced equipment accurately
measures flame spread and combustion characteristics, ensuring
reliable results for quality control and product safety
certification.
Compliance Standards
- UL94: Standard for Safety of Flammability of Plastic Materials for Parts
in Devices and Appliances, developed by Underwriters Laboratories
(UL).
- IEC 60695: International Electrotechnical Commission standard covering fire
hazard testing for materials.
- GB/T 2408: Chinese National Standard for testing the burning behavior of
plastics.
- ASTM D3801: Standard for measuring the vertical burning properties of solid
plastics.
- ASTM D635: Standard for testing the rate of burning of plastics in a
horizontal position.
- GB/T 5169.16: Chinese National Standard for fire hazard testing of
electrotechnical products.
Applications
Plastics
Assesses burning behavior of plastic materials used in various
industries, determining classifications like UL94 HB, V-0, V-1,
V-2, 5VA, or 5VB based on flame spread and extinguishing time.
Representative Products: Polycarbonate sheets, polypropylene components, ABS panels, PVC
insulation, nylon connectors.
Textiles
Evaluates flame resistance of woven, non-woven, or coated fabrics
for various applications.
Representative Products: Polyester upholstery fabric, nylon carpeting, cotton-polyester
blend curtains, aramid protective clothing, acrylic coated fabrics.
Electronics
Examines flammability of materials used in electronic components
and assemblies.
Representative Products: Epoxy resin circuit boards, silicone rubber keypads, polyurethane
foam insulation, thermoplastic connectors, glass-fiber reinforced
composites.
