Test for Flammability of Materials

Введение

This tester is developed base on the standard AS1530.2. test for flammability of materials. The method is applied to the testing of a thin sheet or woven material which is sufficiently pliable to be inserted into the test apparatus by hand without special softening treatment,

so that it may be graded according to a flammability index.

Apparatus

Two parallel brass rails, light gauge angle section which is  formed in length to be slightly convex, with location pin;

All other frames made of stainless steel material;

A 533.4mm scaler is fixed to one side of the mounting frame, with 21 equally space and 25.4mm apart;

Two stainless steel wire alone location pin with lightly tension to a held specimen in position;

Ignition copper trough, with an internal dimension of 20mmx10mmx3mm, with brass support, height-adjustable.

Stainless steel flue and hood;

4 thermocouple, type K, positioned symmetrically within the flue, 570mm above the test specimen;

1 thermocouple, type K, positioned in the control box, monitor ambient temperature;

Labview software with DAQ module for temperature record and the Area (A) calculation;
