GB 17927-2024 sets the safety requirements for the flame resistance of furniture, that is the ability to inhibit, slow down or stop the spread of flame. It applies to the quality control of upholstered furniture and its upholstered parts, and uses the terms of GB/T 28202-2020 plus its own definitions of flame resistance, afterglow and flaming.

It fixes the flame resistance grade required for each typical place of use, including a new grade III, and states the ignition criteria.

The verification chapter covers the test room, the timer and platform, the pretreatment and test climate and three ignition tests, smouldering cigarette, simulated match flame and wood stack, each in a normative annex, then the result determination and the marking.

It replaces GB 17927.1-2011 and GB 17927.2-2011, was issued on 23 August 2024 and has applied since 1 September 2025.

Foreword

This document was drafted in accordance with the rules given in GB/T 1.1-2020 "Directives for standardization - Part 1: Rules for the structure and drafting of standardizing documents".

This document replaces GB 17927.1-2011 "Upholstered furniture -- Assessment of the resistance to ignition of mattress and sofa -- Part 1: Smouldering cigarette" and GB 17927.2-2011 "Upholstered furniture -- Assessment of the resistance to ignition of mattress and sofa -- Part 2: Match flame equivalent". Compared with GB 17927.1-2011 and GB 17927.2-2011, in addition to structural adjustments and editorial changes, the main technical changes in this document are as follows.

a) Flame-retardant grade III has been added (see Chapter 4 of this Edition);

b) The test method for ignition source of wood pile has been added (see 6.6 of this Edition);

c) The length of the cigarette has been changed from (60±5) mm to (55±5) mm (see A.1 in Annex A of this Edition; 6.2 in GB 17927.1-2011).

3.2 Afterglow

Under specified test conditions, after the fire source is removed or the flaming combustion is terminated, […]

3.3 Flaming

A gaseous combustion process accompanied by luminescence.

4 Requirements

The flame resistance of upholstered furniture and furniture with soft covering parts in typical usage places shall not be lower than the corresponding requirements in Table 1.

5 Ignition criteria

5.1 Afterglow ignition

The following phenomena are considered afterglow ignition.

5.2 Flaming ignition

The following phenomena are considered as flaming ignition.

6 Verification methods

6.1 Test safety facilities

6.1.1 Test chamber

The test chamber can be a room with a volume greater than 20 m³ (containing sufficient oxygen for the test), or a small space with ventilation facilities. The airflow rate around the test bench is 0.02 m/s~0.2 m/s, which does not interfere with the combustion test.

6.4 Ignition test of cigarette ignition source

Perform the test in accordance with the provisions of Annex A.

6.5 Ignition test of simulating match flame ignition source

Perform according to the provisions of Annex B.

6.6 Ignition test of wood pile ignition source

Perform according to the provisions of Annex C.

7 Result determination

7.1 Selection of ignition source

Select the corresponding ignition source in Table 1 according to the place where the furniture is used or the flame-retardant grade requirements.

7.2 Test result determination

Carry out flame-retardant test according to the provisions of Annex A ~ Annex C.
