The Bed Blanket Flammability Tester assesses flame retardancy and surface flame spread of bed blanket fabrics. It burns samples with a standardized flame, observing damage or discoloration on test paper for grading. Featuring a transparent observation window and flame ruler, it evaluates spread speed and damage length. Made of stainless steel, it ensures accurate flow/time control, records burn time, and resets automatically for efficient, user-friendly operation.

Standards

ASTM D4151:Standard Test Method for Flammability of Blanket

GB/T11049-2008:Burning behaviour of carpets - Tablet test at ambient temperature

BS 4790:Method for determination of the effects of a small source of ignition on textile floor coverings (hot metal nut method)

ISO 6925:Textile floor coverings - Burning behaviour - Tablet test at ambient temperature

BS 6307:Method for determination of the resistance to ignition of upholstered furniture (match flame equivalent test)

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.

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.

Features

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.
