This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2010, and conflicting national standards shall be withdrawn at the latest by July 2010. Attention is drawn

15、 to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1313-1:1997. This standard is one of a series concerning sawn timber. Compar

16、ed to EN 1313-1:1997, the following modifications have been made: a) Amendment A1:1999 has been incorporated; b) A new Table 2 giving target cross-sectional sized based on metric measure has been added and tables given in Annex A have been modified accordingly; c) In Annex A: Table A.5 “Complementar

17、y preferred sizes in France“ has been completed and the concept of preferred size for green timber introduced (the fibre saturation point is assumed to be 28 %), Table A.10 “Complementary preferred sizes in Norway“ has been completed and Table A.12 “Complementary preferred sizes in Poland“ has been

18、added. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,

BS EN 1313-1:2010EN 1313-1:2010 (E) 4 1 Scope This European Standard specifies permitted deviations for thickness and width at

20、reference moisture content and adjustments for changes in size due to changes in moisture content. Preferred sizes for thicknesses of 38 mm and over are also specified. This standard applies to softwood sawn timber. An informative annex gives complementary national sizes. NOTE A.5 includes for Franc

21、e the concept of preferred size for green timber. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including a

24、en in EN 844-1:1995, EN 844-3:1995, EN 844-4:1997 and EN 844-6:1997 apply. 4 Reference moisture content The reference moisture content is 20 %. The target sizes in Clause 7 are applied at this moisture content. 5 Change in size due to changes in moisture content Unless there is evidence to the contr

25、ary, it shall be assumed that the thickness and width of a piece of timber will increase by 0,25 % every 1 % of moisture content higher than 20 % up to fibre saturation point, and decrease by up to 0,25 % every 1 % of moisture content lower than 20 %. The above values are independent of the species.

26、 6 Permitted deviations The average thickness and the average width shall not be less than the target sizes. BS EN 1313-1:2010EN 1313-1:2010 (E) 5 Permitted deviations of cross-sectional sizes at 20 % moisture content are as follows: For thickness and width 100 mm: + 3 mm / - 1 mm; For thickness and

27、 width 100 mm: + 4 mm / - 2 mm. For length: no minus tolerance, plus tolerance agreed by contract. 7 Common traditional target cross-sectional sizes Sizes shall be measured according to EN 1309-1. Common traditional target cross-sectional sizes of softwood sawn timber with thickness of 38 mm and ove
