EN 771-5:2011+A1:2015

Specification for masonry units - Part 5: Manufactured stone masonry units

This European Standard specifies the characteristics and performance requirements of manufactured stone masonry units for which the main intended uses are facing or exposed masonry in load bearing or non-load bearing building and civil engineering applications. The units are suitable for all forms of coursed or random masonry walling, including single leaf, cavity, partition, retaining and the external masonry to chimneys. They can provide fire protection, thermal insulation, sound insulation and sound absorption. This standard covers concrete masonry units manufactured to resemble natural stone using casting or pressing techniques with or without textured surfaces produced, by casting, splitting, washing, blasting or tooling and with or without variable outline effects. It covers homogeneous masonry units and those consisting of different facing and backing concrete mixes but excludes those manufactured with an adhesive bonded decorative face. This standard does not cover masonry units intended to conform to EN 771-3. It defines the performance related to e.g. strength, density, dimensional accuracy, surface appearance and provides for the evaluation of conformity of the product to this European Standard. The marking requirements for products covered by this European Standard are also included. This European Standard does not apply to storey height panels, masonry units used for chimney flues or units manufactured with an adhesive bonded decorative face. It does not include products intended to be used as a damp proof course nor does it specify standard sizes for manufactured stone masonry units or work dimensions and angles of specially shaped units. 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 - 5. del: Zidaki iz umetnega kamna

Ta evropski standard določa značilnosti in zahteve za zmogljivost zidakov iz umetnega kamna, ki so predvideni predvsem za uporabo pri fasadni ali izpostavljeni zidavi pri nosilnih ali nenosilnih visokih ali nizkih gradnjah. Zidaki so primerni za vse oblike sten z zidaki v ravnih vrstah ali naključno razporejenimi zidaki, ki vključujejo enoslojne zidove, votle zidove, predelke, oporne zidove in zunanje stene dimnikov. Zagotavljajo lahko zaščito pred požarom, toplotno izolacijo, zvočno izolacijo in zvočno absorpcijo. Ta standard zajema betonske zidake, ki so izdelani tako, da so podobni naravnemu kamnu, z uporabo tehnik ulivanja ali stiskanja, s teksturiranimi površinami ali brez njih, z ulivanjem, cepljenjem, spiranjem, peskanjem ali obdelavo z orodjem in s spremenljivimi učinki orisa. Zajema homogene zidake in zidake, sestavljene iz različnih betonskih mešanic za sprednji in zadnji del, izključuje pa zidake, izdelane z okrasno stranico, vezano z adhezivom. Ta standard ne zajema zidakov, ki so v skladu z EN 771-3. Opredeljuje zmogljivost v zvezi z npr. močjo, gostoto, dimenzijsko natančnostjo, videzom površine ter zagotavlja oceno skladnosti proizvoda s tem evropskim standardom. Vključene so zahteve za označevanje proizvodov, ki jih zajema ta evropski standard. Ta evropski standard ne velja za panele etažne višine, zidake, ki se uporabljajo za dimne cevi dimnikov, ali zidake, narejene z okrasno stranico, vezano z adhezivom. Ne vključuje proizvodov, predvidenih za uporabo kot izolacijska zaščita pred vlago, in ne določa standardnih velikosti za zidake iz umetnega kamna ali delovnih dimenzij in kotov zidakov posebnih oblik. Ne zajema zidakov z vgrajenim materialom za toplotno izolacijo, vezanim na stranice zidaka, ki so lahko izpostavljene ognju.
