Specification for masonry units - Part 4: Autoclaved aerated concrete masonry units
This European Standard specifies the characteristics and performance requirements of autoclaved aerated concrete (AAC) masonry units for which the main intended uses are different types of load bearing and non-load bearing applications in all forms of walling including single leaf, cavity, partitions, retaining, basement and general use below ground level, including walling for fire protection, thermal insulation, sound insulation and the fabric of chimneys (excluding chimney flue units). This European Standard includes AAC masonry units with an incorporated insulation not exposed to fire, and masonry units of an overall rectangular parallelepiped shape, specially shaped and accessory units. AAC masonry units may consist of layers of different densities where not all of the layers are loadbearing. It provides for the assessment and verification of constancy of performance (AVCP) of the product to this European Standard. The marking requirement for products covered by this European Standard is included. This European Standard does not cover the requirements for storey height pa
