Description
FCZ-50 Textile Vertical Flammability Tester | GB/T 5455-2014 Vertical Burn Test Machine for Fabrics
1. Product Overview
The FCZ-50 Textile Vertical Flammability Tester is a professional laboratory instrument strictly developed in accordance with GB/T 5455-2014 Textiles – Burning Behaviour – Determination of Damaged Length, Afterglow Time and Afterflame Time of Vertically Oriented Specimens.
This vertical combustion testing machine is specially designed to evaluate the fire performance of all types of textiles and finished textile products. It accurately measures three core flammability indicators: afterflame time, afterglow time and char damaged length of vertical fabric samples, providing reliable standardized test data for textile factories, garment manufacturers, third-party fire testing labs and textile material R&D institutions.
