Introduction

1. Standard Background and Technical Evolution

GB/T 18101-2024 replaces the previous GB/T 18101-2013, and has made a comprehensive revision to the classification and performance of flame-retardant plywood. The new standard introduces a multi-dimensional safety assessment system, including combustion performance, smoke generation characteristics, smoke toxicity, and combustion droplets/particle levels.

2. Classification and Codes

Classification Dimensions	Grade Division	Applicable Standards
Combustion Performance	Grade B1(B) and Grade B1(C)	GB 8624—2012
Smoke Generation Characteristics	Grades S1, S2, S3	GB 8624—2012
Smoke Toxicity	t0, tl, t2 level	GB 8624—2012
Burning droplets/particles level	d0, dl, d2 level	GB 8624—2012

3. Physical and chemical performance requirements

Flame retardant plywood must meet the following physical and chemical performance indicators:

• Moisture content: Meet the requirements of GB/T 9846—2015.
• Bond strength: Meet the minimum value required by the standard.
• Static bending strength and elastic modulus: Ensure the stability of the material under stress.
• Formaldehyde emission: Classification is carried out according to GB/T 39600-2021.

4. Combustion performance and safety assessment

Combustion performance requirements include:

Flaming growth rate index (FIGRA) ≤ 250 W/s and total heat release (THR600s) ≤ 15 MJ.

Smoke toxicity must reach a quasi-safety level, and burning drops/particles must be controlled to last no longer than 10 seconds.

5. Implementation Suggestions

5.1 Suggestions for manufacturers

• Establish a complete quality control system to ensure that each batch of products meets the requirements of the new standard.
• Adopt advanced flame retardant treatment technology to improve the fire resistance of materials.
• Strengthen employee training to ensure the correct understanding and implementation of the new standard.

5.2 Suggestions for users

• Choose products with QR codes or digital codes for easy traceability and management.
• Choose the appropriate grade according to the specific application scenario (e.g., Class II products for humid environments).
• Regularly check the identification and performance of inventory products to ensure safe use.
