Flammability test chamber SIT

international standards-compliantstainless steel

The Single-Flame Source Test Apparatus, also named Ignitability Apparatus, in accordance with ISO 11925-2, is designed to determine the ignitability of products by direct small flame impingement to vertically mounted specimens without additional irradiance. Single-Flame Source Test is widely used to assess the flammability performance class of construction or railway material, such as EN 13501-1, EN 45545-2, DIN 4102, DIN 5510-2, etc. Single-Flame Source Test Apparatus consists of • Stainless steel made test chamber. • The top of the chamber has a φ150 exhaust chimney. • The bottom of the chamber is 25mm by 25mm by 40mm stainless steel square grid. • Front and side high-temperature resistant glass door for easy observation and operation. • A copper-made burner with an angle adjustable foundation. • Calibrated 45° and 90° burner position, and can be rapidly exchanged. • The burner assembly is installed on a sliding rail, it can be pushed and positioned by an external pusher. • Stainless steel gauge for flame height measuring. • Burner spacer for impingement position measuring. • Precise needle valve for propane gas flow control. • Stainless steel made sample holders.
