Introduction

Core changes in the standard revision

Technical indicators	Requirements of the 2002 version	Requirements of the 2021 version	Change analysis
Classification method	Classification by density	Classification by compression strength/insulation performance/combustion performance	Strengthen engineering application orientation
Thermal conductivity	≤0.041W/(m·K)	≤0.033W/(m·K)	Energy efficiency requirements increased by 24%
Combustion performance	Oxygen index determination	GB8624 classification (B1/B2/B3)	Unified with building materials fire protection standards

Detailed explanation of key technical requirements

1. Innovation of classification system

The new standard establishes a three-dimensional classification matrix:

Compressive strength: 7 levels (Grade I ≥60kPa to Grade VII ≥800kPa)
Insulation performance: Dual-track system of Grade 033/Grade 037
Combustion performance: Three-level division of B1 (difficult to burn) - B3 (flammable)

Application case

A cold chain logistics project selected products marked with EPS-Ⅳ-B1-033, which not only met the load-bearing requirements (200-300kPa) of -18℃ cold storage, but also met the B1 fire protection zone standard.

Test method upgrade

Key test parameters adjustment

Test items	Specimen size change	Environmental control
Water absorption	100mm→150mm	Water temperature(23±2)℃
Dimensional stability	Thickness25±1mm	70℃/48h

Implementation suggestions

Manufacturers need to upgrade the foaming process control system, especially the dispersion uniformity of graphite-modified EPS
Project acceptance should focus on the ±5mm deviation control of products with thickness > 100mm
Testing agencies need to configure a guarded hot plate method thermal conductivity meter (GB/T10294) as an arbitration method
