45 Degree Flammability Tester

The 45° flammability tester consists of a control system and a combustion chamber. The sample is mounted on a sample holder in the combustion chamber at a 45° angle. The burner is positioned close to the sample, and the sample is ignited with a flame for a specified time before the burner is withdrawn. The burning behavior of the sample and the flame spread rate on the sample are observed to evaluate the ignitability and flame propagation performance of the sample.

Testing Standards

ASTM D1230. FTMS 191-5908. CFR 16 Part 1610. CALIF TB 117. NFPA 702. GB/T 14644

Applications

45 degree flammability tester is designed to determine the burning characteristics of textiles. Stainless steel test cabinet with glass observation panel, provided with automatic timing of flame spread in 0.1 second increments from ignition. Ignition time free Settings.

Structure

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;

45 Degree Flammability Tester Testing principle

1. Combustion intensity and speed test

Under specified conditions, the sample is placed at an Angle of 45 degrees, the sample is ignited for 1s, and the time required for the sample to burn upward with flame for a certain distance is used as a measure to evaluate the intensity of the textile combustion. The fabric with surface flapping is used as an additional indicator for the intensity of combustion.

2.Damage area and length test

Under the specified test conditions, the textile samples were ignited in the direction of 45 degrees, and the after burning and smoldering time, damage area and damage length of the fabric after combustion were measured.

3.Times of touch with flame test

Under the specified test conditions, the textile samples were ignited in the direction of 45 degrees, and the number of times of touch with flame was measured when the fabric was burned 90mm from the lower end of the sample.

FAQs

How is the 45 Degree Flammability Tester used in an industrial setting?

The tester is employed to assess the flammability characteristics of various materials by exposing specimens at a 45-degree angle to a controlled flame. This process helps industries determine the fire resistance of their products, ensuring compliance with safety standards.

What materials can be tested with this flammability tester?

The unit is suitable for a variety of materials including textiles, plastics, foams, and other components commonly used in manufacturing processes that require fire safety certification.

When should this tester be used during product development?

It is best used during the quality assurance and safety evaluation phases of product development. Testing before final product release is vital for ensuring that goods meet regulatory and safety requirements.

Where is the 45 Degree Flammability Tester typically installed?

Due to its modest size and sturdy build, it can be set up in laboratories, research centers, or directly within industrial plants to provide immediate and accessible fire resistance testing.

What is the operating process for the tester?

To operate, position the sample material at a 45-degree angle on the specimen holder, apply the flame as per the standardized method, and observe the material's reaction to the ignition source. The device's electric mechanism provides stable and reliable operation throughout the testing procedure.

What are the benefits of using this tester for manufacturers and exporters?

Utilizing this tester ensures that products comply with national and international flammability regulations, enhancing marketability and consumer trust. Its robust design and precise measurements help manufacturers maintain consistent quality and safety standards.
