Test requirements for 45 Degree Automatic Flammability Tester
  • 2018-10-19 18:21:12
45 Degree Automatic Flammability Tester is mainly used for apparel fabrics, decorative fabrics, tent fabric, such as the determination of flame retardant performance, is composed of control system and combustion chamber, the sample is installed in the combustion chamber is 45 ° Angle of tilt of sample frame, make the fire mouth close to the sample, with the flame returned sample stipulated time, observation sample combustion condition and speed of the spread of flame on the sample, evaluation of ignition and flame spreading performance of the sample.
The scope of application of the commonly used test standard for the 45 degree combustion tester is described below to help the user make a correct judgment on the standard.
GB/T 14768 rules on the carpet in laboratory conditions, the control of 45 ° inclined to put the carpet sample surface under the effect of flame combustion performance test methods and assessment. Suitable for carpets with various fiber components and tissue structures. The test results obtained in GB/T 14768 do not apply to the evaluation of carpet combustion performance at other test locations and risk of carpet under actual fire conditions.

Test principle:
Under specified test conditions, the surface of 45 ° inclined put carpet sample ignition time, measuring the sample follow up time and the length of the damaged, smoldering combustion time.

Test requirements:
1. The experimental results shall calculate the arithmetical mean values of the longitudinal and transverse afterburning time, smolder time and damage length of the sample respectively. The duration of afterburning and smolder is accurate to 0.1s, and the length of damage is accurate to 1mm.
2.45 ° combustion technology indexes should comply with the regulations of the following table. 45 ° burning technical indicators:

Test items:

Longitudinal    damage length(mm)     continued, smolder time(s )

Horizontal      100 and below          20 and below
