Introduction

Interpretation of the core content of the standard

Technical dimensions	Ordinary building boards	Special building boards
Fire resistance classification	0.5-3.0 hours (building fiber)	0.5-3.0 hours (HC hydrocarbons)
Environmental tolerance	Basic weathering requirements	Acid/alkali/salt spray/freeze-thaw cycle resistance
Combustion performance	FIGRA≤250W/s	Additional high temperature impact test

Detailed explanation of key technical indicators

Fire resistance test: The standard stipulates that HN400×200 steel (section coefficient 161m^-1) and 36b I-steel (126m^-1) are used as the base material, and four-point loading is used to simulate the actual stress state. The judgment conditions include:

Bearing capacity: deformation ≤L/20 (L is the clear span)
Temperature control: average temperature ≤538℃

Implementation suggestions

Selection guide:Petrochemical projects should choose TS composite panels (such as HCGB-TS Fac2.00-F22), whose chemical corrosion resistance is verified by a 30-day salt spray test. High-rise buildings are recommended to use PT D-type panels (such as HCGBE-PT Fxn1.50-D16), with a surface density of ≤25kg/m².

Installation points:The standard emphasizes that the 150mm lightweight concrete cover should be used in conjunction with aluminum silicate fiber wool for cladding construction, and the maintenance environment should be controlled at 5-35℃/50-80%RH.
