1. Instrument usage and applicable standards
Fabric vertical The flame retardant tester is suitable for measuring the flame retardant properties of clothing fabrics, decorative fabrics, tent fabrics, etc. that have flame retardant requirements. It can be used by wool spinning, cotton spinning, chemical fiber, printing and dyeing and other industries as well as textile inspection departments, scientific research units and colleges and universities.
II. Working Principle
Fabric vertical method flame retardant instrument retards fabrics The principle of flame performance measurement adopts the vertical method, that is, by measuring a vertical strip of cloth (fabric) that burns for a certain period of time, and then determines the flame retardant performance of the fabric based on parameters such as burning time, smoldering time, and damage length.
Afterburning time: Under the specified test conditions, the time the material continues to burn with flame after the fire source is removed.
Smoldering time: Under specified test conditions, the time the material continues to burn without flame after the flaming combustion has terminated or the fire source is removed. .
Damage length: Under the specified test conditions, the maximum length of the material damage area in the specified direction.
3. Main specifications and technical characteristics of the instrument
1. Burner: Adopt Federa Type I has an inner diameter of 11mm, an inclination of 25°, and the burner’s moving motor consumes 10w of power.
2. The ignition timing can be preset arbitrarily within 0.1~999.9s, and the national standard adopts 12s.
3. The afterburning time and smoldering time timing range is 0.1~9999.9s (minimum 0.1s)
4. Flame height measuring device: ruler height 40mm.
