Fabric Flame Retardant Tester
A Fabric Flame Retardant Tester is a specialized laboratory instrument designed to evaluate the flammability characteristics of textiles. It assesses how fabrics react to direct flame exposure, measuring parameters such as ignition time, flame spread rate, after-flame duration, and afterglow time. This testing is crucial for ensuring that textiles meet safety standards for various applications, including apparel, home furnishings, and industrial uses.
Purpose and Applications
The primary purpose of a Fabric Flame Retardant Tester is to determine the flame resistance of textile materials. This is essential for:- Apparel Safety: Ensuring garments, especially children’s sleepwear and industrial work wear, meet flammability standards.
– Home Textiles: Testing curtains, drapes, upholstery, and bedding for fire safety compliance.
– Technical Textiles: Evaluating materials used in tents, protective clothing, and automotive interiors.
⚙️ Key Features
Modern Fabric Flame Retardant Testers incorporate several features to ensure accurate and reliable testing:- Adjustable Burner Angles: Allowing tests at various orientations (e.g., 0°, 45°, 90°) to simulate different real-world scenarios.
Automated Ignition Systems: Providing consistent flame application and reducing operator variability.
– Digital Timing Mechanisms: Accurately recording ignition time, flame spread, after-flame, and afterglow durations.
– Transparent Observation Windows: Enabling safe monitoring of the test without exposure to hazards.
– Compliance with International Standards: Meeting protocols such as ASTM D6413, ISO 6941, and EN ISO 15025 for standardized testing procedures.
Testing Standards
Fabric Flame Retardant Testers are designed to comply with various international standards, including:
– ASTM D6413: Standard Test Method for Flame Resistance of Textiles (Vertical Test).
– ISO 6941: Textiles — burning behavior — Measurement of flame spread properties of vertically oriented specimens.
– EN ISO 15025: Protective clothing — Protection against heat and flame — Method of test for limited flame spread.
️ How It Works
- Sample Preparation: A fabric specimen is cut to specified dimensions and conditioned as per standard requirements.
- Mounting: The sample is mounted vertically or at a specified angle in the testing chamber.
- Ignition: A controlled flame is applied to the fabric for a predetermined time.
- Observation: The tester records ignition time, flame spread, after-flame time, and afterglow time.
- Evaluation: Results are compared against standard criteria to determine compliance.
✅ Benefits
– Safety Assurance: Ensures textiles meet fire safety regulations, reducing risk in end-use applications.
– Quality Control: Identifies flammability issues during the manufacturing process.
– Regulatory Compliance: Helps manufacturers meet legal requirements for flammability.
– Product Development: Assists in developing flame-retardant materials for specialized applications.

How to Use a Fabric Flame Retardant Tester (Vertical Flammability Test Method):
- Prepare the Sample
– Cut the fabric to standard dimensions (usually 300 × 75 mm).
– Condition the fabric for 24 hours at 21°C and 65% relative humidity.
- Mount the Sample
– Place the fabric vertically in the frame inside the test chamber.
– Ensure it’s held securely with no folds or slack.
- Set Up the Burner Position the burner at the required angle (usually 90° for vertical tests).
– Adjust flame size according to the standard (about 38 mm for ASTM D6413).
- Ignite the Flame – Apply the flame to the bottom edge of the fabric for 12 seconds.
- Observe and Measure – Start timing when flame is applied.
– Measure:
– After-flame time (how long it burns after flame removal)
– After-glow time (how long it glows after burning stops)
– Char length (distance burned vertically)
- Record the Results
– Repeat the test on multiple samples (usually 5) and calculate averages.
- Compare with Standards
– Evaluate whether the results meet the required flame resistance limits.
