Aerated concrete blocks are described as follows
Example: Aerated concrete DIN V 4165 PPSW 2 –0.40 – 624 – 748x240x2100
DIN V 4165 = Aerated concrete
standard P = Aerated concrete
P = Stone type: Flat block, high dimensional accuracy
PE = Stone type: Flat element
SW = Stone type: System wall element
2 = Stone compressive strength class 0.40
= Stone bulk density class
748x240x2100 = Stone format, 248x240x248
