Carpet Flammability Tester (GB/T 11049, BS 4790, ISO 6925)

The Carpet Flammability Tester is designed to evaluate the ignitability and flame-spread characteristics of carpets and textile floor coverings when exposed to a small ignition source. According to different international requirements, the instrument supports two test methods: the Hot Metal Nut Method and the Methenamine Tablet Method.

It provides accurate, repeatable results that help manufacturers assess fire safety performance and meet mandatory regulatory standards for commercial and residential carpeting.

Application

This tester is widely used to determine how carpets react when subjected to a small flame or ignition source. It is suitable for:

Residential carpets and rugs

Commercial and office floor coverings

Automotive carpets and mats

Hospitality and public-use carpeting

Textile flooring materials requiring regulatory flammability approval

The instrument helps users identify materials with unacceptable ignition or flame-spread behavior, ensuring compliance with safety requirements and reducing fire hazards in public and household environments.

Standards

The Carpet Flammability Tester meets the following international standards:

GB/T 11049-2008 — Flammability of textile floor coverings

BS 4790 — Determination of the effects of a small source of ignition on textile floor coverings

ISO 6925 — Textile floor coverings — Burning behavior

BS 6307

CPSC 16 CFR 1630/1631 — Standard for the surface flammability of carpets and rugs (USA)

Product Construction

The test chamber is constructed from flame-retardant, heat-resistant panels to ensure stable test conditions and operational safety.

A smooth sliding platform allows users to place and remove samples with ease.

A top-mounted inspection mirror provides a clear viewing angle, enabling operators to observe the flame spread and char length throughout the test without interfering with the burning zone.

Product Features

Integrated measuring grid and locating ring

Ensures precise sample positioning and accurate char-length evaluation.

Smooth, easy-to-operate sliding platform

Facilitates convenient sample loading and safe operation.

Overhead observation mirror

Allows operators to clearly monitor flame behavior without opening the chamber.

Supports two recognized test methods

Hot Metal Nut Method and Methenamine Tablet Method can be performed on one instrument.

Enhanced operational safety

Heat-resistant construction and controlled test area help protect the user during testing.

FAQ

1. What does this tester evaluate?

It measures how carpets ignite and how far flames spread when exposed to a small ignition source, helping users determine compliance with flammability regulations.

2. What test methods are supported?

The instrument supports both the Hot Metal Nut Method (commonly used in BS/ISO tests) and the Methenamine Tablet Method (required in CPSC 16 CFR 1630/1631).

3. What types of carpet materials can be tested?

All types of textile floor coverings, including woven, tufted, flocked, needle-punched, and fusion-bonded carpets.

4. Is the tester safe to operate?

Yes. The flame-retardant chamber, sliding sample platform, and overhead mirror allow safe operation without exposing the user to flame or heat.

5. Which industries commonly use this device?

Carpet manufacturers, flooring manufacturers, automotive interior suppliers, testing laboratories, and product certification organizations.
