Horizontal Combustion Tester

Product Overview

The Horizontal Combustion Tester is a standardized instrument designed to evaluate the flame propagation characteristics of textiles, plastics, and composite materials under controlled horizontal flame exposure. It quantifies ignition resistance, flame spread rate, and self-extinguishing behavior in compliance with international fire safety standards.

Type: Horizontal flame propagation tester

Test Standards: ASTM D6413. ISO 6941. NFPA 701

Key Metrics:

Flame Spread Time (seconds)

Char Length (mm)

Afterflame Duration (seconds)

Sample Size: 610×1220mm (horizontal clamping)

Technical Specifications

Key Features
