45 Degree Automatic Flammability Tester

45 Degree Automatic Flammability Tester test instrument is used to detect the flame resistance of the blanket fabric and the flame spread performance of the fabric surface.including bed sheets, blankets, mattresses, pillows, duck down quilts and plush fabric products used to cover the bed.

Application

The 45 Degree Automatic Flammability Tester is suitable for flammability testing of various textile products, including:

(1) Bedding textiles — bed sheets, blankets, mattresses, pillows, and quilts.

(2) Plush and fleece fabrics — evaluating surface burning behavior.

(3) Home textiles — fabrics used for covering and decorative purposes.

(4) Textile manufacturers — quality control of flame resistance performance.

(5) Testing laboratories — standardized flammability evaluation.

Standards

(1) 16 CFR Part 1610 — Standard for the Flammability of Clothing Textiles

(2) ASTM D1230 — Standard Test Method for Flammability of Apparel Textiles

(3) GB/T 14644 — Test Method for Burning Behaviour of Textile Fabrics at 45°

(4) ISO 6940 — Textile Fabrics — Burning Behaviour — Determination of Ease of Ignition of Vertically Oriented Specimens

(5) ISO 6941 — Textile Fabrics — Burning Behaviour — Measurement of Flame Spread Properties

Technical Parameters

▶ Flowmeter :  Adjust the gas flow size;
▶ Fire tube :  The gas is first connected to the flow meter through the hose, and then through the rear hose of the box into the flame pipe;
▶ Windscreen:  the upper part of the windshield is provided with glass;
The experiment was carried out in a ventilated kitchen. The round hole on the top of the box and the gap on the windshield make the gas convection.
▶ Control panel : Power- power switch ;Start:Start internal motor operation. When the flame tube moves to the test position (the vertical distance from the sample center is 8mm, the horizontal distance is 3.2mm), the internal timing switch is touched;
▶ Reset : Timer reset /Fire tube reset;
▶ Sample clamp and specimen holder : The sample frame substrate is provided with a knob which can adjust the left and right movement, and the sample frame substrate is moved and fixed by loosening and tightening the knob;
▶ Timer :Display settings and actual ignition time.After the time is cleared, the fire tube can complete the required movement. Or the fire tube can not return to the original position after moving forward;
▶ Test room size: W368 × D216 × H356 mm

▶ Sample shelf angle: 45°

▶ Flame spread time setting range: 0.01S-99.99S
▶ ignition time of the sample surface : 1.0S ± 0.05S

Test principle

Within a specified time, the surface of the test sample is burned with a standardized flame, so that the burning, damage degree or discoloration of the standard test paper can be observed, and then the test fabric can be graded and evaluated.

FAQ

(1) What does a 45 Degree Flammability Tester measure?

It measures flame spread time and evaluates how a fabric burns when exposed to a controlled flame at a 45° angle.

(2) Which materials can be tested?

It is suitable for bedding textiles, plush fabrics, and other surface textile materials.

(3) Why is the 45° angle used?

The 45° angle simulates real usage conditions and allows consistent evaluation of flame spread behavior.

(4) How is flame spread evaluated?

By recording the time it takes for the flame to travel across the specimen and observing burning damage or discoloration.

(5) How to choose a suitable flammability tester?

Selection depends on applicable standards, material type, and test requirements. QINSUN engineers can recommend suitable equipment based on your application. Contact us for professional support.
