Timber structures - Glued laminated timber and glued solid timber

This European Standard sets the performance requirements of the following glued laminated products: - Glued laminated timber (glulam); - Glued solid timber; - Glulam with large finger joints; - Block glued glulam for use in buildings and bridges. It also lays down minimum production requirements, provisions for evaluation and attestation of conformity and marking of glued laminated products. This European Standard is applicable for glued laminated timber made of coniferous species listed in this standard or poplar consisting of two or more laminations having a thickness from 6 mm up to 45 mm (inclusive). It may be possible to produce glulam made from specific hardwood species based on some provisions of this European Standard. In this case, Annex ZA does not apply. This European Standard is applicable for glued solid timber made of coniferous species listed in this standard or poplar consisting of two to five laminations having a thickness greater than 45 mm and less than or equal to 85 mm. This European Standard is applicable for large finger joints in glued laminated timber with a finger length of at least 45 mm. This European Standard is applicable for block glued glulam having solid rectangular cross sections. This European Standard also gives the requirements for glued laminated products treated against biological attack. Glued laminated products treated with fire retardants are not covered.

Določa tudi minimalne zahteve glede proizvodnje ter določila za vrednotenje in potrjevanje skladnosti in označevanje lepljenih lameliranih izdelkov. Ta evropski standard se uporablja za lepljeni lamelirani les, izdelan iz iglavcev, ki so navedeni v tem standardu, ali topolovine, ki je sestavljena iz dveh ali več laminatov z debelino od 6 mm do 45 mm (vključno). Na osnovi nekaterih določil tega evropskega standarda obstaja možnost izdelave glulama iz določenega lesa listavcev. V tem primeru dodatek ZA ne velja. Ta evropski standard se uporablja za lepljeni masivni les, izdelan iz iglavcev, ki so navedeni v tem standardu, ali topolovine, ki je sestavljena iz dveh ali več laminatov z debelino, ki je večja od 45 mm in manjša od ali enaka 85 mm. Ta evropski standard se uporablja za zobate spoje velikega formata v lepljenem lameliranem lesu, pri čemer je dolžina zoba vsaj 45 mm. Ta evropski standard se uporablja za blokovno lepljeni glulam s polnimi pravokotnimi prerezi. Ta evropski standard določa tudi zahteve za lepljene lamelirane izdelke, ki imajo zaščito pred biološkimi dejavniki.
