Flame Tube Combustion Tester for Fire-Retardant Wood
The Flame Tube Combustion Tester for Fire-Retardant Wood is designed to evaluate the mass loss rate and flaming combustion time of indoor decorative wood products (D=20 mm) treated with fire-retardant chemicals under specified burning conditions. The instrument meets the technical specifications and requirements of GA/T 42.2-92.
Applications
This tester is suitable for:
(1) Fire performance testing of fire-retardant treated indoor wood panels, flooring, and furniture components.
(2) Quality control of flame-retardant wood in interior decoration and building materials.
(3) Assessment of mass loss and flaming time for research and development of fire-retardant treatments.
(4) Compliance testing for fire safety certification of wood-based materials.
(5) Laboratory testing for wood treatment manufacturers and material testing institutes.
Standards
(1) GA/T 42.2-92: Combustion test for flame-retardant treated wood products.
(2) ISO 5660: Reaction-to-fire tests – Heat release, smoke production, and mass loss.
(3) ASTM D 545: Standard test methods for evaluating the fire resistance of treated wood.
(4) EN 13501-1: Fire classification of construction products and building elements.

FAQ
(1) What is this product?
A flame tube combustion tester for evaluating fire-retardant treated wood under controlled flame conditions.
(2) What is it used for?
It measures the flaming combustion time and mass loss of treated wood for quality control and fire safety compliance.
(3) What types of this product exist?
Variants may differ in flame tube size, control method (manual or PLC), and sample dimensions.
(4) What industry problems can it solve?
Ensures fire safety compliance, evaluates effectiveness of wood fire-retardant treatments, and supports R&D of flame-retardant materials.
(5) How is it operated?
The treated wood sample is placed in the flame tube; gas flow, flame height, and timing are controlled via the panel or PLC. Observations and data on mass loss and flaming duration are recorded for analysis.
