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). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

Safety technical specification of flame resistance for furniture

1 Scope

China's mandatory technical regulation on the fire retardant performance of furniture - the upholstered seating and mattresses that are, in a domestic fire, both the first thing ignited and the thing that decides how fast the room becomes unsurvivable. A modern sofa or mattress is a large mass of foam and textile, and once it is properly alight it can take a room to flashover in a few minutes, producing dense smoke and carbon monoxide well before the flames reach anyone. The regulation exists to break that chain at the start: the ignition. It specifies the requirements, the inspection rules and the marking for the flame resistance of furniture, and describes the corresponding verification methods. The requirements are built on the two ignition sources that actually start these fires - the smouldering cigarette and the small open flame, a match or a lighter - and the test methods apply each to the composite as it is assembled, with its cover fabric, its interliner and its filling together, because that is what determines the outcome. A fabric and a foam that each pass alone can fail as a pair, and the reverse also happens, which is why the regulation refuses to certify components in isolation. Around that sit the inspection rules and the marking, which is what allows a purchaser, a hotel or a building operator to specify compliant furniture and to prove afterwards that they did. As a mandatory technical specification the document is a market access requirement: furniture that does not satisfy it may not be sold. Issued on 23 August 2024 and in force since 1 September 2025, it replaces GB 17927.1-2011.

This document specifies the requirements, inspection rules and marking for the flame resistance of furniture. It describes the corresponding verification methods. This document applies to the quality control of upholstered furniture and furniture upholstered parts.
