Blanket Flammability Test Machine

Bevezetés

Bed Blanket Flammability Tester is used to detect the flame retardant performance of the bed blanket fabric and the flame spread property of the fabric surface. This test method is to burn the surface of the sample with a standardized flame within a specified time, thereby observing the burning, damage degree or discoloration of the standard test paper. And then, the test fabric is graded. Good repeatability of experimental data can help manufacturers effectively control production and verify product performance.

1. The instrument is mainly used to test the flame retardant performance of materials such as bed blankets. The front safety door of the instrument adopts a transparent observation window and a standard burner equipped with a flame ruler. The result can be used to evaluate the flame spread speed and damage length of the material after ignition under the standard, it provides data basis for new material research and development, product quality acceptance and the like.

2.The combustion box is made of stainless steel, high temperature resistant, smoke resistant, easy to clean after use, imported flow control accessories and timing module ensure accurate flow and time control of the instrument, and record the burning time. The instrument adopts button design. the ignition is automatically Reset after ignition, ready for the next test, easy to operate, easy to use, and efficient.

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.

ASTM D4151 Standard Test Method for Flammability of Blankets

Field Application:

Bed Blanket Flammability Tester-It is mainly used for testing the flame retardant performance of bed blanket fabric and flame spreading performance of fabric surface.

The instrument is also suitable for the performance verification of new products developed, quality control of production departments, product performance verification of third-party testing institutions, and the measurement of material performance by laboratories and quality and technical supervision departments.

Operation

● After the sample is ready and the instrument is commissioned, place the assembled sample clamp on the specimen holder.

● Open the gas valve and supply the gas to the fire pipe. Use the electronic igniter to fire the burner

● Press the start button on the control panel. The fire tube moves forward and moved to the test position under the action of the mechanical transmission. Then, Start the ignition of the sample and test paper on the sample holder

● At the same time to start the ignition timing system, the control panel display and record the ignition time. After a second,  the fire tube moving backwards, the timer stop time. The experiment is end.

● Finally remove the sample and test paper for rating.

Jellemzők

Stainless steel body design

External gas control;Separation design of fire source is safe and reliable, it has the functions of fine gas adjustment and coarse adjustment; The instrument with stainless steel main body is resistant to high temperature and smoke, easy to clean and long service life.

time recording module

High precision digital display timer with 0.1s accuracy, built in standard 1s ignition time, automatically burns and records the time.

flexible specimen holder design

The positioning accuracy of the sample holder ensures the consistency of the position of each combustion and reduces the uncertainty of the test, thus ensuring the accuracy of the test.

Standard burner

The burner of the instrument adopts the standard 18# needle. The compact design ensures the stability of the flame, and it is automatically reset to prepare for the next test after each ignition. It is very convenient to use.
