Analysis of the flame retardant properties of carpets

Different scenarios require different flame-retardant properties for carpets, typically determined by fire risk level, pedestrian density, escape needs, and regulatory requirements. Below is a detailed explanation by common application scenarios:

Specific Requirements for Carpet Flame-Retardant Properties in Various Application Scenarios

1. Residential Spaces

Requirement Level: Generally B2 (combustible material)

Standard Reference:

China: GB 8624-2012 B2 level is sufficient.

USA: ASTM D2859 (passing the Pill Test is sufficient).

Note: Residential buildings have lower pedestrian traffic. The fire risk is relatively low, and the flame retardant requirements are relatively lenient. However, it is still recommended to use flame-retardant carpets to improve safety.

2. Commercial Buildings (Office Buildings, Shopping Malls, Hotel Lobbies, etc.)

Requirement Level: **B1 (Flame-Retardant)** or higher

Standard Reference:

China: GB 8624-2012 B1 level.

EU: EN 13501-1 Cfl-s1 or Bfl-s1.

Notes: These areas often have high traffic density and large spaces, which makes it difficult to escape. Therefore, carpets with high flame retardancy ratings and low smoke density (s1) are required in these areas.

3. Medical Institutions (Hospitals, Nursing Homes)

Requirement Level: B1 or higher

Standard Reference: May involve GB/T 20239, NFPA, EN 13501-1, etc.

Notes: Hospitals have a large number of people with mobility impairments, requiring extremely high fire resistance and low smoke toxicity. Carpeting may not be recommended in some areas, such as ICUs.

4. Schools, Libraries, Educational Institutions

Requirement Level: B1 or higher

Notes: These are places with high concentrations of youth, requiring strict control of fire source spread and toxic smoke generation.

5. Cinemas, Theaters, Conference Centers

Requirement Level: B1 or EN Bfl-s1

Notes: Dark environments and high-density crowds places like movie theater require carpet materials with extremely high flame retardancy and low smoke density for rapid evacuation.

6. Hotel Guest Room Area

Requirement Level: Hotel guest rooms may be upgraded to B2 level, but public corridors and stairwells must meet B1 level.

Note: Note: Carpets for 5 star hotels or hotel guest room carpets are often used for aesthetic and comfort reasons, but must meet fire retardant regulations. 

7. Interior Design of Transportation (Airplanes, High-Speed Railways, Subways, Buses)

Requirement Level: Extremely high standards, generally exceeding civil building requirements.

Standard Reference:

Airplanes: FAR 25.853 (US) or CS 25.853 (Europe).

High-Speed Railway/Subway: EN 45545-2 (Fire Protection Standard for Railway Materials).

Note: Escape space in carriages is limited, making fire control extremely critical. Carpets must be self-extinguishing, non-dripping, and produce low-toxic smoke.

Summary:

Dongsheng's Axminster carpet and nylon printed carpet have passed EN 13501, ASTM E648, and ASTM D2859 flame retardant performance tests, meeting the flame retardant requirements of different areas. Welcome to purchase.
