Horizontal and Vertical Flame Testers: Key to Accurate Flammability Assessment

In sectors such as electronics, automotive manufacturing, and building materials, the flame retardancy of materials is a critical safety indicator. Professional and accurate assessment of flame retardant ratings relies on a core piece of equipment—the Horizontal and Vertical Flame Tester. This apparatus simulates combustion scenarios under specific conditions, providing essential data support for material research, development, and quality control.

Core Testing Functions & Standards

The Horizontal and Vertical Flame Tester is primarily used to evaluate the burning behavior of materials in horizontal or vertical orientations. Its key measurement parameters include:

• Burning Rate: Quantifies the speed at which flames spread across the material's surface.
• After-flame / After-glow Time: Measures the duration flames or glowing combustion persist after the ignition source is removed.
• Effect of Burning Droplets: Assesses whether droplets produced during combustion ignite a cotton indicator placed below.

This data is the direct basis for determining material flame retardancy ratings (such as HB, V-0. V-1. V-2 under UL 94) and ensures compliance with core domestic and international standards like UL 94. GB/T 2408. and IEC 60695-11-10.

Analysis of Main Application Scenarios

The tester's applications span several key industries:

• Electronic Appliance Insulating Materials: Evaluating the flame retardancy of plastic components like sockets and casings to prevent fires caused by circuit faults.
• Automotive Interiors and Components: Testing the flame resistance of interior textiles, wire harness insulation, and other materials to meet stringent automotive safety regulations.
• New Energy Vehicle Safety: Conducting rigorous vertical flame tests on battery pack components and charging pile materials is crucial for ensuring battery safety.
• Building Materials and Textiles: Used for flame retardancy verification of products like wall insulation materials and protective clothing fabrics.

Key Equipment Advantages

• Accurate and Reliable Data: High-precision ignition systems and timing devices ensure test results are repeatable and comparable.
• Safe and Standardized Operation: Integrated safety protection design effectively safeguards operators and equipment.
• Efficient Compliance: Helps companies quickly verify product compliance and provides authoritative test reports for market access globally.

For manufacturers and testing institutions, equipping a high-precision Horizontal and Vertical Flame Tester is not only a requirement for enhancing product quality control but also a vital technical safeguard for strengthening product market competitiveness and earning customer trust.
