Specification for masonry units - Part 2: Calcium silicate masonry units

This European Standard specifies the characteristics and performance requirements of calcium silicate masonry units for which the main intended uses are inner walls, outer walls, cellars, foundations and external chimney masonry.
This European Standard is intended to apply to all calcium silicate masonry units, including those of an overall nonrectangular parallelepiped shape, specially shaped and accessory units.
It defines the performance related to e.g. strength, density and dimensional accuracy, measured according to the corresponding test methods contained in separate European Standards.
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 document is also included.
This European Standard does not specify standard sizes for calcium silicate masonry units, nor standard work dimensions and angles of specially shaped and accessory units.
It does not cover units with more than 60 % volume of voids, nor products made from shale as a major raw material.
It does not cover storey height panels.
It does not cover units intended for use as a damp proof course, nor units with an incorporated thermal insulation material bonded to the faces of the unit susceptible to be exposed to fire, nor chimney flue units.

Specifikacija za zidake - 2. del: Apneno peščeni zidaki

Ta evropski standard določa značilnosti in zahteve za zmogljivost apneno peščenih zidakov, ki so predvideni predvsem za uporabo pri zidavi notranjih sten, zunanjih sten, kleti, temeljev in zunanjosti dimnikov.
Ta evropski standard velja za vse apneno peščene zidake, vključno z zidaki nepravokotne paralelepipedne oblike, zidaki posebnih oblik in pomožnimi zidaki.
Opredeljuje zmogljivosti v zvezi z npr. močjo, gostoto in dimenzijsko natančnostjo, izmerjeno v skladu z ustreznimi preskusnimi metodami, navedenimi v ločenih evropskih standardih..
Omogoča »ocenjevanje in preverjanje nespremenljivosti zmogljivosti (AVCP)« proizvodov v skladu s tem evropskim standardom. Vključena je tudi zahteva za označevanje proizvodov, ki jih zajema ta dokument.
Ta evropski standard ne določa standardnih velikosti za opečne zidake niti ne določa standardnih delovnih dimenzij, kotov in polmerov opečnih zidakov posebnih oblik.
Ne zajema zidakov z več kot 60 % praznega prostora in proizvodov, narejenih iz skrilavca kot glavne surovine.
Ne zajema panelov etažne višine.
Ne zajema zidakov, ki se uporabljajo kot izolacijska zaščita pred vlago, zidakov z vgrajenim materialom za toplotno izolacijo, vezanim na stranice zidaka, ki so lahko izpostavljene ognju, ali zidakov za dimne cevi dimnikov.
