EN 771-4:2011+A1:2015

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 panels, flue linings and masonry units with an incorporated thermal insulation material bonded to the faces of the unit susceptible to be exposed to fire. It does not specify standard sizes for autoclaved aerated concrete units nor standard work dimensions and angles of specially shaped and accessory units. It does not give permissible deviations for specially shaped and accessory units. It does not cover products intended for use as a damp proof course or the lining of a chimney.

Specifikacija za zidake - 4. del: Zidaki iz avtoklaviranega celičnega betona

Ta evropski standard določa značilnosti in zahteve za zmogljivosti za zidake iz avtoklaviranega celičnega betona, ki so predvideni predvsem za uporabo pri raznovrstnih nosilnih in nenosilnih aplikacijah pri vseh oblikah sten, vključno z enoslojnim zidom, votlim zidom, predelki, opornimi stenami, kletmi in splošno uporabo pod zemljo, ki vključuje stene za zaščito pred požarom, toplotno izolacijo, zvočno izolacijo in strukturo dimnikov (razen dimnih cevi).
Ta evropski standard vključuje zidake iz avtoklaviranega celičnega betona z vgrajeno toplotno izolacijo, ki ne bo izpostavljena ognju, ter zidake nepravokotne paralelepipedne oblike, zidake posebnih oblik in pomožne zidake. Zidaki iz avtoklaviranega celičnega betona so lahko sestavljeni iz plasti različnih gostot, pri čemer vse plasti niso nosilne.
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 zajema zahtev za panele etažne višine, obloge dimnih cevi in zidake z vgrajenim materialom za toplotno izolacijo, vezanim na stranice zidaka, ki so lahko izpostavljene ognju. Ne določa standardnih velikosti za zidake iz avtoklaviranega celičnega betona niti ne določa standardnih delovnih dimenzij in kotov zidakov posebnih oblik in pomožnih zidakov. Ne podaja dovoljenih odstopanj za zidake posebnih oblik in pomožne zidake. Ne zajema proizvodov, ki se uporabljajo kot izolacijska zaščita pred vlago ali obloga dimnika.
