This European Standard specifies test methods for determining the strength and deformation characteristics of stapled joints in load-bearing timber structures. The methods assess joints with members of timber (solid timber and glued laminated timber) or wood-based products in the combination proposed for use in service and using all types of staples up to 3 mm diameter for circular cross-section staples or 4 mm x 2 mm for rectangular or oval cross-section staples. The methods determine load-slip characteristics and maximum load of joints with laterally loaded staples where various angles between the applied force and the timber grain direction or the main direction of the wood-based products, respectively, are possible.

EN 14081-1:2016 木材结构.矩形截面的强度等级结构木材.第1部分:要求

This European Standard specifies requirements for strength graded structural timber with rectangular cross-sections either visual or machine graded, shaped by sawing, planning or other methods and with cross-sectional dimensions complying with EN 336 (referred to as structural timber in the following clauses). This European Standard includes provisions for test methods, Assessment and Verification of Constancy of Performance and marking of structural timber. NOTE 1 For machine strength graded timber additional provisions for type testing (TT) are given in EN 14081-2 and for factory production control (FPC) in EN 14081-3. NOTE 2 An acceptance procedure for verification of a lot is given in EN 14358 which may be used for a delivery of structural timber. This European Standard identifies characteristics for which limits have to be given in visual grading standards. This European Standard covers structural timber, untreated or treated against biological attack. This European Standard does not cover:- timber treated by fire retardant products to improve its fire performance; - thermally and/or chemically modified timber; - structural finger jointed timber.

EN 16351:2015 木材结构.木材交叉叠层.要求

This European Standard sets out provisions regarding the performance characteristics for straight and curved structural cross laminated timber (X-Lam) both without and with large finger joints as a material for the manufacture of structural elements to be used in buildings and bridges. This European Standard applies to cross laminated timber: to be used in service class 1 or 2 according to EN 1995-1-1; made of coniferous species and poplar listed in 5.1.5 of this standard; built up of at least three orthogonally bonded layers (at least two of them timber layers); having, depending on the number of layers, adjacent layers which may be bonded parallel to the grain; made of timber layers which are made of strength graded timber according to EN 14081-1; made of timber layers having thicknesses between 6 mm and 60 mm (including) taking into account the layup requirements given in this European standard; made of timber layers which may be edge bonded or which are not bonded and have spacing less than 6 mm between adjacent laminations; which may comprise wood based panel layers made of structural wood based panels specified in this European standard, fulfilling the requirements for use in service class 2 or 3 according to EN 1995-1-1, having no structural joints between the single panels and having thicknesses between 6 mm and 45 mm (including); bonded with adhesives, fulfilling the requirements given in this European standard; having overall thicknesses up to 500 mm; which is not made from reused timber or wood based panels comprising reused timber. This European Standard also applies to cross laminated timber with large finger joints: made from cross laminated timber pieces having the same cross section and layup; made from cross laminated timber pieces having cross sectional thicknesses from 51 mm up to 345 mm (inclusive) and minimum thicknesses of the outermost layers not less than 17 mm; made from cross laminated timber pieces solely comprising timber layers; made from plane cross laminated timber pieces jointed so that no regular change between the grain directions of the layers occurs; with finger joints having a finger length of at least 45 mm and fingers which are visible at the two narrow sides of the components. This European Standard applies to cross laminated timber treated against biological attack. Cross laminated timber treated with fire retardants is not covered. It also sets out minimum production requirements and procedures for Assessment and Verification of Constancy of Performance.

This Technical Specification specifies a method for determining the performance of a preservative, applied to the upper surface of the mortar test specimens, in preventing the growth of dry rot through the treated mortar when exposed to the test fungus. This method is only applicable to masonry fungicides applied as a true solution of the preservative in water or dilute oil in water emulsion. It is not applicable to rods, pastes and other similar preservative types. This method is applicable to preservatives applied to masonry by brushing, spraying and/or injection techniques or mixed into rendering and plastering mortar for masonry.
