Fire-Retardant Standards in Hotel Furniture: A Practical Guide to GB 8624, B1 Grade, and Material Selection by Zone

In hotel furniture customization projects, fire retardancy is a hard line that cannot be crossed. Whether it appears in a domestic five-star hotel tender document or the technical specifications of an overseas apartment furniture export order, the required fire-retardant grade is always clearly stated. Yet many procurement professionals only half-understand terms like "B1 grade," "GB 8624," and "BS 5852" — they know compliance is required, but they do not fully grasp what these standards mean for material and process selection.

This article explains fire retardancy in hotel furniture from a manufacturing perspective.

1. GB 8624 and B1 Grade: The Logic Behind China's Fire Rating System

China's core standard for building material and furniture fire performance classification is GB 8624. It categorizes materials into four grades: Grade A (non-combustible), B1 (difficult to ignite), B2 (combustible), and B3 (highly flammable). Hotel furniture typically requires B1 grade — meaning the material resists ignition, self-extinguishes when the flame source is removed, and produces smoke and toxic gases within defined limits.

It is important to understand that "B1 grade" is an umbrella term. The specific test methods and evaluation criteria differ across material types. For fabrics, testing typically measures afterflame time, afterglow time, and char length. For wood panels, smoke production rate is also evaluated. So two fabrics both labeled "B1 fire-retardant" may have been tested using entirely different methods — one via vertical burn testing, another via oxygen index. Procurement teams should verify that the test method on the report matches the material type.

2. Zone-Specific Fire-Retardant Requirements

Different functional areas within a hotel have different fire-retardant requirements, typically managed by risk level:

Guest Rooms: Headboard upholstery, curtains, bedding, and carpets are the primary fire-retardant focus. Headboard fabrics generally need to meet B1 grade, and foam padding must undergo fire-retardant treatment. Wardrobes and TV cabinets made of panel furniture already possess inherent fire resistance, but surface veneer materials must also meet smoke density requirements.

Public Areas (Lobby, Corridors, Banquet Halls): Higher foot traffic means stricter fire safety requirements. Lobby sofas and lounge chair fabrics and foam must achieve B1 grade, and some high-standard hotel projects also require fabrics to pass both smoke density and toxicity tests. Fixed furniture such as wood wall paneling and reception desk surfaces must use fire-retardant substrates or fire-retardant lacquer finishes.

Dining Areas: Upholstered portions of dining chairs require fire-retardant treatment, and tabletop materials must demonstrate heat resistance and fire-retardant properties. Movable partitions and folding doors in banquet halls, due to their large combustible surface area, are subject to even more stringent fire-retardant grade requirements.

3. Manufacturing Pathways for Fire Retardancy

There are three primary pathways to achieve fire retardancy in furniture:

Inherently Fire-Retardant Materials: Using fire-retardant MDF or fire-retardant plywood as substrates. These panels have fire-retardant additives integrated during manufacturing and achieve B1 grade at the factory. They cost more but deliver consistent performance, making them suitable for quality-driven hotel projects.

Surface Treatment: Applying fire-retardant paint or coatings to standard panel surfaces to create a protective fire barrier. This approach is more cost-effective, but performance depends heavily on coating thickness and application technique, requiring strict control of coverage rates.

Fabric Post-Treatment: Upholstery fabrics achieve fire retardancy through impregnation or coating processes. It is worth noting that some treated fabrics lose fire-retardant performance after repeated washing — hotel procurement teams should pay attention to the fabric's wash durability rating.

In Rongtai's production practice, guest room upholstery fabrics and foam are sourced to B1 grade standards, and substrates are selected as E0 or ENF grade fire-retardant panels based on project positioning. The factory maintains an independent fire-retardant material inspection process — each batch of fabric and panels is checked against test reports upon arrival, with sampling retests conducted when necessary to ensure material performance matches specifications.

4. International Standards: What Export Projects Need to Know

For overseas hotel and apartment furniture export, the most commonly encountered international fire-retardant standards include:

• UK BS 5852: A fire-retardancy test for upholstered furniture using ignition sources such as a cigarette and a match flame equivalent. The UK market generally requires hotel furniture to pass BS 5852 Source 5 testing.
• US CAL 117: California's standard for upholstered furniture fire retardancy, focusing on fabric and filling material performance. Note that the CAL 117-2013 revision updated test methods — version differences must be verified.
• EU EN 1021: Similar to BS 5852, testing upholstered furniture against cigarette and match flame ignition sources. Commonly required for hotel projects in the EU market.

Different countries and regions emphasize different aspects of fire safety. When confirming technical specifications for export projects, it is essential to verify the applicable fire-retardant standard version and test method line by line with the buyer — avoiding misunderstandings that could lead to full-batch rejection.

5. Conclusion

Fire retardancy is not a label to be applied — it is a complete system spanning material procurement, process selection, and finished product inspection. For a hotel furniture customization factory, the ability to consistently deliver fire-retardant-compliant products tests the maturity of its supply chain management and quality control systems.

Foshan Rongtai Furniture Co., Ltd. has been deeply engaged in hotel furniture and apartment furniture customization for over a decade. Its 77,000-square-meter facility is equipped with complete panel furniture and upholstered furniture production lines, and has passed FSC, CQC, and ISO 9001 certifications. In fire-retardant material application, the factory has established a full-process control system from material procurement inspection to finished product sampling — providing fire-retardant furniture solutions that meet standards for hotel projects worldwide.
