(Main)Specification for masonry units - Part 3: Aggregate concrete masonry units (Dense and lightweight aggregates)
Specification for masonry units - Part 3: Aggregate concrete masonry units (Dense and lightweight aggregates)
This European Standard specifies the characteristics and performance requirements of aggregate concrete masonry units made from dense and lightweight aggregates or a combination of both for which the main intended uses are common, facing or exposed masonry in load bearing or non-load bearing building and civil engineering applications. The units are suitable for all forms of walling, including single leaf, external leaf to chimneys, cavity wall, partitions, retaining, and basement. They can provide fire protection, thermal insulation, sound insulation and sound absorption.
This European Standard includes aggregate concrete masonry units of an overall non-rectangular parallelepiped shape, !specially" shaped and accessory units.
It defines the performance related to e.g. strength, density, dimensional accuracy, and 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 specify standard sizes for aggregate concrete masonry units, nor standard work dimensions and angles of specially shaped aggregate concrete masonry units. It does not cover storey height panels, chimney flue linings nor units intended for use as a damp proof course. It does not cover units with an incorporated thermal insulation material bonded to the faces of the unit susceptible to be exposed to fire.

Specifikacija za zidake - 3. del: Betonski zidaki (kompaktni in lahki agregati)
Ta evropski standard določa značilnosti in zahteve za zmogljivost betonskih zidakov, narejenih iz kompaktnih in lahkih agregatov ali kombinacije obojega, ki so predvideni predvsem za uporabo pri splošni, fasadni in izpostavljeni zidavi pri nosilnih ali nenosilnih visokih ali nizkih gradnjah. Zidaki so primerni za vse oblike sten, vključno z enojnim slojem in zunanjim slojem pri dimnikih, votlih zidovih, predelkih, opornih zidovih in kleteh. Zagotavljajo lahko zaščito pred požarom, toplotno izolacijo, zvočno izolacijo in zvočno absorpcijo.
Ta evropski standard vključuje betonske zidake nepravokotnih paralelepipednih oblik, zidake »posebnih« oblik in pomožne zidake.
Opredeljuje zmogljivost v zvezi z npr. močjo, gostoto in dimenzijsko natančnostjo ter omogoča ocenjevanje in preverjanje nespremenljivosti zmogljivosti (AVCP) proizvodov v skladu s tem evropskim standardom. Vključena je zahteva za označevanje proizvodov, ki jih zajema ta evropski standard.
Ta evropski standard ne določa standardnih velikosti za betonske zidake niti ne določa standardnih delovnih dimenzij in kotov betonskih zidakov posebnih oblik. Ne zajema panelov etažne višine, oblog za dimne cevi za dimnike ali zidakov, ki se uporabljajo kot izolacijska zaščita pred vlago. Ne zajema zidakov z vgrajenim materialom za toplotno izolacijo, vezanim na stranice zidaka, ki so lahko izpostavljene ognju.
