BS EN 1927-3:2008 软木圆材的定性分类.落叶松和花旗松

This Standard specifies the qualitative classification for the roundwood of larches (Larix) and Douglas fir (Pseudotsuga). The classification is made either using Clauses 4 and 5 or using informative Annex A. Clauses 4 and 5 describe the qualitative classification of round timber for which the intended use is unknown. Annex A gives a list of characteristics which serves as guideline for contracts describing qualities for round timber of larches and Douglas fir where the intended use is known.

This European Standard specifies the qualitative classification for the roundwood of pines. It applies to Scots pine (Pinus sylvestris), Corsican or Austrian pine (Pinus nigra), maritime pine (Pinus pinaster) and radiata pine (Pinus radiata). The classification is made either using Clauses 4 and 5 or using Annex A. Clauses 4 and 5 describe the qualitative classification of round timber for which the intended use is unknown. Informative Annex A gives a list of characteristics which serves as a guideline for contracts describing qualities for round timber of pines where the intended use is known.

ASTM D3345-08 木材及其他纤维素材料防白蚁破坏的实验室评定试验方法

1.1 This test method covers the laboratory evaluation of treated or untreated cellulosic material for its resistance to subterranean termites. This test should be considered as a screening test for treated material and further evaluation by field methods is required. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. (Warning8212;See 6.1.4.)

DIN EN 942:2007 细木制作用木材.一般要求

This European Standard specifies the general requirements including in particular the grading and classification by appearance quality of timber in joinery products or individual joinery parts. This European Standard is intended to be used at the time of manufacture of a product. Howerer this Standare may be used to evaluate products at a later stage, but in these situations storage and service conditions, subsequent to manufacture,shall be taken into account(surface checks). Where European Standard covers solid,finger-jointed,end-jointed,edge-jointed and laminated timber products. Matters relating to the influence of timber characteristics on strength and durability are not covered in this Standard.

BS 5756:2007 硬木的外观分级.规范

This British Standard specifies a method of strength grading tropical and temperate hardwood visually for structural use. For tropical hardwoods, the permissible limits of characteristics for a single visual strength grade of timber are specified, designated “Structural Tropical Hardwood” (HS) grade. For temperate hardwoods, the permissible limits of characteristics are specified for two visual strength grades for large size timber, designated “Heavy Structural Temperate Hardwood” (THA and THB), and two visual strength grades for smaller size timber, designated “General Structural Temperate Hardwood” (TH1 and TH2). This British Standard applies to hardwoods, graded for use in the United Kingdom, for both within the United Kingdom and abroad.

This document lisual strength grades, species and sources of timber, and specifies the strength classes from EN 338, to which they are assigned. NOTE For the grades, species and sources included, there is long experience of use and/or satisfactory test data. The sources listed are therefore largely determined by existing commercial practice.

ASTM D7381-07 标准材料试验中桩用圆木允许应力的建立用标准实施规程

This practice is primarily intended for use by associations, third-party grading agencies, technical societies and other groups that develop national design standards and use recommendations for round timber piles. This practice provides procedures for establishing compression parallel to grain and bending stresses for round timber piles including: sampling of material for testing; methods of test and property calculation procedures; distribution analysis of test data; procedures for determining adjustments for critical section location; pile oversize, load sharing and treatment; and procedures for deriving allowable stresses. In using allowable stresses established under this practice, factors specific to each end use which may affect the performance of the pile system shall be considered by the designer. Such factors include the location of the critical section, the bearing capacity of the soil, the ability of the pile to withstand driving forces, the properties of the cap or load distributive element tying piles together and the loading and conditions of service.1.1 This practice contains procedures for establishing allowable compression parallel to grain and bending stresses for round timbers used for piling, based on results from full-size tests.Note 1Allowable stresses for compression perpendicular to grain and shear properties are established in accordance with the provisions of Practice D 2899.1.2 Stresses established under this practice are applicable to piles conforming to the size, quality, straightness, spiral grain, knot, shake and split provisions of Specification D 25.1.3 A commentary on the practice is available from ASTM International.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
