V. overall dimensions:

Approximately 254 x 254mm(1 x 1 in.)

Test standard:

16 CFR 1510, ASTM F963 4.6.2

Test principle:

Fixed samples were placed on the nail bed to determine the ignition source of the sample, observe the combustion state of the sample, and evaluate the combustion performance of the sample.

Test method:

1. Place the sample on the equipment and measure the length;

2. For a candle with a flame height of 16mm, ignite 5s on the sample at the top of the flame, remove the flame, and then burn 5s or burn to the other end of the main shaft to calculate the burning rate.
