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.Cross References:EN 1995-1-2EN 13238EN 350-2EN 384EN 13501-1EN 16485EN 844-9EN 14081-2EN 15804EN 13183-2EN 844-7EN 13823EN 13501-2EN 13556EN 350-1EN 1912EN 13183-3EN ISO 3166-1EN 844-10EN 14081-3EN 338EN 15228:2009EN 1310:1997EN ISO 9001EN 15942EN 336EN 16449EN 14358EN 335Incorporates the following:Amendment, August 2019
