Carpet Flammability Tester ISO 6925 BS 6307 BS 4790 Floor Covering Hot Metal Nut & Methenamine Tablet Ignition Test Machine

This carpet flammability tester is professionally developed to evaluate the reaction of floor coverings and carpet materials under small ignition sources. It supports two classic test methods: the hot metal nut test (BS 4790) and the methenamine tablet test (ISO 6925, BS 6307).

The test chamber is built with non-combustible, heat-resistant panels and fitted with a counterweight sliding door for convenient specimen loading and unloading. An angled observation mirror installed inside the chamber allows operators to clearly observe the burning state of samples throughout the entire testing process without opening the cabin.

It is an essential laboratory instrument for carpet and vinyl flooring manufacturers, textile floor covering producers, third-party fire testing laboratories and inspection institutions.

• Dual-test integrated design — one machine meets three international standards, saving laboratory procurement cost and bench space.
• High-temperature, non-combustible chamber structure for stable operation and long service life.
• Built-in angled viewing mirror enables real-time monitoring of sample combustion behavior.
• Counterweight sliding panel opens and closes easily, safely and with minimal effort.
• Measuring grid and clamping ring ensure accurate sample positioning and consistent test repeatability.
• Complete supporting accessories: M16 hot nut, methenamine tablets and fixture kits for both test modes.

Suitable for fire performance testing of all types of floor coverings, including tufted carpet, woven carpet, textile floor mats, PVC floor covering, linoleum flooring and rubber floor materials.
