Fire Retardant Coating Tester – Large Plate Method
Category：Flammability Tester
Introduction
The Fire Retardant Coating Tester (Large Plate Method) is designed to evaluate the fire resistance of decorative coatings in laboratory conditions, following national standards. The instrument measures combustion mass loss and chemical volume to assess the effectiveness of fire-retardant coatings. It features high automation, precise temperature control, and touchscreen operation for reliable and user-friendly testing.
Application
The flame-retardant coating tester (large panel method) is widely used for determining the flame resistance characteristics and burning time of fire-retardant coatings. These devices comply with the GB12441-2005 standard, ensuring the accuracy and reliability of the test results. The main parameters of the tester include power requirements, temperature uniformity, sample size, temperature control system, thermocouples, timer accuracy, and automatic alarm, all of which ensure the stability and safety of the testing process.
Standards
GB12441-2018: Finishing fire resistant coating
GB12441-2005 : Finishing fire retardant paint
