Different ignition sources are applied to a constructed test rig to examine the burning behavior of a test material.
A test rig is constructed in order to simulate a chair with the fabric to be tested. This rig is subjected to different ignition sources. There are 8 types of ignition sources, each with different heat intensity. They are classified from 1 to 8, the intensity doubling compared to the preceding source. The most frequently used are ignition source 0, 1 and 5.
Source 0: smoldering cigarette A cigarette is put along the crevice of the test rig and allowed to burn over its entire length. If no flaming or progressive smoldering is observed on both cover and interior material, the test is recorded as no ignition and the material passes the test.
Source 1: simulated match A burner is lit, held along the crevice of the test rig for 20 seconds and then removed. If no flaming or progressive smoldering is observed on both cover and interior material, the test is recorded as no ignition and the material passes the test.
Source 5: wooden crib 5 A crib is composed of wooden planks, glued together. Lint is attached to the bottom. After adding propane-diol the crib is placed on the test rig and ignited with a match. If no flaming or progressive smoldering is observed on both cover and interior material, the test is recorded as no ignition and the material passes the test.
The test material passes or fails this test.
