　　4 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.

　　Marking examples: strength level A5 bulk density level B05, superior

In the city.　　, becoming an important component of new building materials.

　　There are seven strength levels: A0, A0, A5, A5, A0, and A

.　　3 Blocks are divided into three levels based on dimensional deviation, appearance quality volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).

　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.

　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions, stacking,In the cityautoclaved aerated concrete block,, and transportation of autoclaved aerated concrete blocks.
