ZB 51004-1985 "Fire-proof coatings fire performance classification standard"

This standard applies to the classification of fire-proof coatings for interior decoration in buildings. The types of fire-proof coatings and their performance indicators are defined, including the classification of veneer and mastic fire-proof coatings, flame propagation ratio, weight loss, carbonization volume and flame resistance time. Based on these indicators, fire-proof coatings are divided into three performance levels, and coatings are required to maintain good fire protection performance during the effective use period. The standard also specifies labeling requirements to ensure the correct use and effect of fire-proof coatings.
