Fire-Retardant Wood Stack Combustion Tester

The Fire-Retardant Wood Stack Combustion Tester is designed to evaluate the mass loss rate and flaming combustion time of fire-retardant treated wood with a thickness greater than 20 mm under specified burning conditions. The instrument features automatic ignition, automatic timing, and auto-reset functions, ensuring repeatable and precise testing.
Applications
This tester is suitable for:
(1) Fire performance testing of fire-retardant treated solid wood panels, beams, and large wood blocks used in construction.
(2) Quality control of flame-retardant treated wood in flooring, furniture, and interior decorative elements.
(3) Assessment of flaming duration and mass loss for R&D of fire-retardant wood treatments.
(4) Laboratory testing for compliance with fire safety certification of thick wood products.
(5) Evaluation of wood stack fire behavior in real-world combustion scenarios.
Standards
(1) GA/T 42.1-92: Fire-retardant wood combustion test method – Wood stack method.
(2) ISO 5660: Reaction-to-fire tests – Heat release, smoke production, and mass loss.
(3) ASTM D 5516: Standard test methods for evaluating fire-retardant wood in bulk.
(4) EN 13501-1: Fire classification of construction products and building elements.

FAQ
(1) What is this product?
A wood stack combustion tester for evaluating fire-retardant treated thick wood under controlled flame conditions.
(2) What is it used for?
It measures mass loss and flaming time of thick fire-retardant 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 maximum sample thickness.
(4) What industry problems can it solve?
Ensures fire safety compliance, evaluates effectiveness of wood fire-retardant treatments, and supports R&D of thick flame-retardant wood materials.
