Introducing Our Advanced Fire Retardant Coatings Tester (Tunnel Method)

We are thrilled to introduce our new Fire Retardant Coatings Tester (Tunnel Method), a cutting-edge instrument designed to rigorously evaluate the flame propagation characteristics of fire retardant coatings. This specialized tester is crucial for manufacturers, R&D departments, and certification bodies focused on ensuring the safety and performance of treated substrates under controlled laboratory conditions.

This system provides an essential means to assess how effectively a fire retardant coating protects its underlying material and how it behaves when exposed to flame, setting a new standard for testing precision and reliability in fire safety.
 

Precision Testing for Critical Fire Safety

Our Fire Retardant Coatings Tester operates by subjecting coated substrates to a precisely controlled flame environment, simulating real-world fire scenarios in a safe, repeatable manner. The core of its advanced performance lies in its meticulously calibrated technical parameters:

Optimized Burner Design: The system features a robust burner with a top diameter of 20mm and a height of approximately 200mm.1 This design ensures a consistent and stable flame application to the test sample.

Controlled Blue Flame Temperature: The burner maintains a precise blue flame temperature of (900 ± 20) °C.2 This critical control ensures that every test is conducted under identical and highly repeatable thermal conditions, allowing for accurate comparative analysis of coating performance.

Versatile Gas Source Compatibility: The tester is compatible with common combustible gas sources, including natural gas, liquefied petroleum gas, or city gas.3 This flexibility ensures ease of integration into various laboratory setups.

High-Precision Temperature Monitoring: Equipped with an armored thermocouple of work-grade precision (K division and outer diameter not greater than 3mm), the system accurately monitors temperatures during the test.4 The readings are processed by an electronic potentiometer with an error of less than ±0.5% of the measured temperature, guaranteeing reliable data acquisition.

Reliable Ignition System: A high-voltage electronic ignition system ensures quick, safe, and consistent flame ignition at the start of each test, contributing to the system's overall efficiency and ease of use.
 

Designed for Optimal Laboratory Performance

To ensure consistent and accurate results, the Fire Retardant Coatings Tester is built to perform within specific, controlled working conditions:

Ambient Temperature: Operates optimally between 5°C and 35°C.

Relative Humidity: Designed for environments with relative humidity not exceeding 85%.6

Working Environment: Suitable for indoor use without forced ventilation, preventing external airflow from affecting flame behavior during testing.7

Power Supply: Requires a standard AC200–240V, 50HZ power supply, compatible with most laboratory electrical infrastructures.
 

Key Applications & Benefits

This innovative tester is an indispensable tool for:

Product Development: Assisting manufacturers in developing and optimizing new fire retardant coating formulations.

Quality Control: Ensuring that production batches of coatings consistently meet performance standards.

Certification & Compliance: Providing critical data for regulatory compliance and product certification.

Research & Academia: Facilitating in-depth studies on flame propagation mechanisms and material protection.

By providing a precise and repeatable method for evaluating fire retardant coatings, our new Fire Retardant Coatings Tester (Tunnel Method) empowers industries to develop safer products and contribute to higher standards of fire protection.
