BS ISO 22390:2020 木结构 单板层积材 结构特性

What is ISO 22390 about?    ISO 22390 specifies the requirements for establishing the characteristic properties of structural laminated veneer lumber (LVL) including 5th percentile strength values, stiffness characteristics and other performance characteristics that are related to its use as a structural product for dry use.   Note: Under ISO 22390 the assessment of formaldehyde requirements, biological durability, fire performance or manufacturing such as quality control and marking are not covered.  Who is ISO 22390 for?   ISO 22390 on structural properties of LVL is useful for:

BS ISO 19993:2020 木结构 胶合层压木材 面和边接头解理测试

What is ISO 19993 about?   ISO 19993 discusses face and edge joint cleavage tests for glued laminated timber in timber structures. ISO 19993 is an international standard that provides effective evaluation for glued laminated timber joints.   ISO 19993 specifies methods to evaluate the effectiveness of glued laminated timber face and edge bonds within a manufacturing plant by cleaving glue lines in both dry and wet conditions.   ISO 19993 is used as a factory quality assurance test to be used for structural glulam and applied to the face and edge joints of each production batch.   Methods specified under ISO 19993 are based on the principle that if the minimum wood failure percentages are met then bond strength exceeds the perpendicular to the grain tension strength stating that the bond is not the weak element that limits the integrity of a glulam assembly.

What is ISO 22389-2 about?    ISO 22389 is an International Standard that discusses timber structures. ISO 22389-2 is the second part of a multi-part series that specifies requirements for manufacturing in-house quality assurance and periodic re-evaluation of prefabricated wood-based I-beams.     ISO 22389-2 specifies the component performance and manufacturing requirements for prefabricated wood-based I-beams that are used as structural members in bending applications.   Note 1: Fire performance, formaldehyde requirements, and biological durability are not covered under ISO 22389-2.   ...

ISO 19993:2020 木材结构 - 胶合层压木材 - 面和边缘接缝切割试验

This document specifies methods of evaluating the effectiveness of glued laminated timber face and edge bonds within a manufacturing plant by cleaving of the glue line in both dry and wet conditions. It is not intended that it be used for initial type testing where cyclic delamination or block shear is preferred. It is based on the principle that, provided minimum wood failure percentages are met, then the bond strength exceeds the perpendicular to the grain tension strength of the under-lying substrate and therefore the bond is not the weak element limiting the integrity of a glulam assembly.

ISO 22389-2:2020 木结构 - I型梁的弯曲应用 - 第2部分:组件性能和制造要求

This document specifies the component performance and manufacturing requirements for prefabricated wood-based I-beams used as structural members in bending applications. It does not cover fire performance, formaldehyde requirements and biological durability. This document gives requirements for manufacturing, in-house quality assurance and periodic re- evaluation of prefabricated wood-based I-beams. Wood-based I-beams tested according to this document are intended for use in covered conditions and utilizing components that are able to resist the effects of moisture on structural performance due to construction delays or other conditions of similar severity, but not permanently exposed to the weather. NOTE The service conditions are similar to “Service class 2” as defined in ISO 20152-1. Testing, evaluation and performance characterization requirements for prefabricated wood-based I-beams are covered in ISO 22389-1. This document 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 document to establish appropriate health and safety practices and determine the applicability of regulatory limitations prior to use.

ISO 22390:2020 木材结构 - 层压单板木材 - 结构性能

This document specifies requirements for establishing the characteristic properties of structural laminated veneer lumber (LVL), including 5th percentile strength values, stiffness characteristics and other performance characteristics, related to its end use as a structural product for dry use (service class 1). It is applicable to members used in flatwise or edgewise bending orientations. It does not cover the assessment of formaldehyde requirements, biological durability, fire performance or manufacturing, such as quality control and marking.

EN ISO 8970:2020 木结构.机械紧固件接头试验.木材密度要求

This document specifies a method based on density, for the selection of pieces of wood used in determining the strength and stiffness properties of joints between members of structural timber made with mechanical fasteners. It is intended to be used in conjunction with a test standard specifying a test method. It is assumed that the wood pieces are conditioned to the relevant conditions, that the wood density is normally distributed and that any deviations are reported. This document is applicable only to specimens of structural timber. NOTE It is emphasized that the wood density is only one of the properties that can influence the strength of a joint. Other relevant properties are, for example, growth-ring size and orientation, toughness and hardness.

ASTM D3957-09(2020) 用于建筑物结构构件应力等级的标准做法

1.1 These practices cover the visual stress-grading principles applicable to structural wood members of nonrectangular shape, as typically used in log buildings. These practices are meant to supplement the ASTM standards listed in Section 2, which cover stress-grading of sawn lumber and round timbers. Pieces covered by these practices may also be used in building types other than log buildings. 1.2 The grading provisions used as illustrations herein are not intended to establish grades for purchase, but rather to show how stress-grading principles are applied to members used in log buildings. Detailed grading rules for commercial stress grades which serve as purchase specifications are established and published by agencies that formulate and maintain such rules and operate inspection facilities covering the various species. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical 1 These practices are under the jurisdiction of ASTM Committee D07 on Wood and are the direct responsibility of Subcommittee D07.02 on Lumber and Engineered Wood Products.
