CAN/ULC-S109 Standard Test Name:

CAN/ULC-S109: Flame tests of flame-resistant fabrics and films

CAN/ULC-S109: Flame Tests of Flame-Resistant Fabrics and Films

CAN/ULC-S109 Test Methods:

The CAN/ULC S109(R2019) test method includes small flame tests and large flame tests. Flame-resistant fabrics and films must meet the requirements of both small and large flame tests.

（1）Small Flame Test

The sample is placed in a metal holder.

A Bunsen burner is suspended below the lower end of each sample, supplied with uniformly mixed natural gas or methane.

A flame is applied near the center of the lower end of the sample for 12 seconds. The duration of surface burning and the damage length are observed.

（2）Large Flame Test

The folded sample is suspended vertically, with the bottom positioned 100 mm above the center of the opening of a Bunsen burner with an inner diameter of 9.5 mm.

The burner is supplied with uniformly mixed natural gas or methane.

The flame is applied for 120 seconds, and the duration of surface burning and the damage length are observed.
