Standard Test Methods for End Joints in Structural Wood Products

SIGNIFICANCE AND USE
4.1 These test methods are applicable to specimens with or without specific conditioning regimens. Tests are permitted to be performed on specimens that are not at moisture equilibrium, such as under production conditions in a plant, or on specimens that have been conditioned to specified moisture content or durability conditioning prior to testing.  
4.2 These test methods can be used as follows:  
4.2.1 To standardize the determination of strength properties for the material and joint being tested.  
4.2.2 To investigate the effect of parameters that may influence the structural capacity of the joint, such as joint profile, adhesive type, moisture content, temperature, and strength-reducing characteristics in the assembly.  
4.3 These test methods do not intend to address all possible exposure or performance expectations of end joints. The following are some performance characteristics not considered:  
4.3.1 Long-term strength and permanence of the wood adhesive.  
4.3.2 Time dependent mechanical properties of the joint.  
4.3.3 Elevated temperature performance of the joint.
SCOPE
1.1 This standard provides test methods for evaluating the structural capacity and integrity of end joints in structural wood products.  
1.2 Off-line test methods include: (1) Axial Tension, (2) Bending, and (3) Cyclic Delamination.  
1.3 In-line test methods include: (1) Tension Proofload and (2) Bending Proofload.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Evaluating System Effects in Repetitive-Member Wood Assemblies

ABSTRACT
This guide identifies the variables to consider when evaluating the performance of repetitive-member wood assemblies for parallel framing systems. This guide discusses general approaches to quantifying an assembly adjustment including limitations of methods and materials when evaluating repetitive-member assembly performance, and does not address the techniques for modeling or testing of such.
SCOPE
1.1 This guide identifies variables to consider when evaluating repetitive-member assembly performance for parallel framing systems.  
1.2 This guide defines terms commonly used to describe interaction mechanisms.  
1.3 This guide discusses general approaches to quantifying an assembly adjustment including limitations of methods and materials when evaluating repetitive-member assembly performance.  
1.4 This guide does not detail the techniques for modeling or testing repetitive-member assembly performance.  
1.5 The analysis and discussion presented in this guideline are based on the assumption that a means exists for distributing applied loads among adjacent, parallel supporting members of the system.  
1.6 Evaluation of creep effects is beyond the scope of this guide.  
1.7 This guide does not purport to suggest or establish appropriate safety levels for assemblies, but cautions users that designers often interpret that safety levels for assemblies and full structures should be higher than safety levels for individual structural members.  
Note 1: Methods other than traditional safety factor approaches, such as reliability methods, are increasingly used to estimate the probability of failure of structural elements. However, the extension of these methods to assemblies or to complete structures is still evolving. For example, complete structures will likely exhibit less variability than individual structural elements. Additionally, there is a potential for beneficial changes in failure modes (that is, more ductile failure modes in systems). These considerations are beyond the scope of this guide.  
1.8 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.9 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.10 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D7470-21(Practice)
Standard Practice for Evaluating Elevated Temperature Performance of End-Jointed Lumber Studs

SIGNIFICANCE AND USE
5.1 End-jointed lumber studs used in fire resistance-rated assemblies shall be able to support the superimposed design load for the specified time under an elevated temperature exposure, when a wall assembly is exposed to a standard fire specified in Test Methods E119. Light-weight wood assemblies utilize gypsum wallboard or other types of membrane protection to accomplish a requisite fire resistance rating for the assembly. However, wood studs and the end joints in the studs shall resist the developed elevated temperature environment for the duration of the rating. This practice provides a method for evaluating the elevated temperature performance of an assembly constructed with end-jointed studs having fire performance comparable to an assembly constructed with solid-sawn studs.
SCOPE
1.1 This practice is to be used to evaluate the elevated temperature performance of end-jointed lumber studs.  
1.2 A symmetric wall assembly containing end-jointed lumber studs is exposed to a standard fire exposure specified in Test Methods E119.  
1.3 End-jointed lumber studs are deemed qualified if the wall assembly resists a standard fire exposure specified in Test Methods E119 for a period of 60 min or more. Qualification of end-jointed lumber studs are restricted to the joint configuration and adhesive tested.  
1.4 This practice is used to evaluate the performance of end-jointed lumber studs to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment under actual fire conditions.  
1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.  
1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practices for Establishing Stress Grades for Structural Members Used in Log Buildings

ABSTRACT
These practices cover the visual stress-grading principles applicable to structural wood members of nonrectangular shape, as typically used in log buildings. The grading provisions presented 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.
SCOPE
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 conversions to SI units that are provided for information only and are not considered standard.  
1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D7672-19(Specification)
Standard Specification for Evaluating Structural Capacities of Rim Board Products and Assemblies

ABSTRACT
This specification provides procedures for testing and establishing the structural capacities of proprietary rim board products and assemblies for use in light-frame wood construction using I-joist or structural composite lumber joist framing. This specification also establishes several procedures used to test rim board products and assemblies, to judge their acceptability, and to establish allowable design capacities.
SCOPE
1.1 This specification provides procedures for testing and establishing the structural capacities of proprietary rim board products and assemblies for use in light-frame wood construction using I-joist or structural composite lumber joist framing. This specification does not apply to commodity rim board products.  
1.2 This specification was developed in light of currently manufactured panel, structural composite lumber, and pre-fabricated I-joist rim board products as defined in 3.2. Materials that do not conform to the definitions of 3.2 are beyond the scope of this specification.  
1.3 Fire safety, sound transmission, building envelope performance, and cutting/notching attributes of rim board products and assemblies fall outside the scope of this specification.  
1.4 This specification primarily considers end use in dry service conditions, such as most protected framing members, where the equilibrium moisture content for solid-sawn lumber is less than 16 %.  
1.5 This specification provides methods to establish “allowable stress” design resistances for use with the National Design Specification for Wood Construction (NDS). Derivation of design resistances from the test data in accordance with “load and resistance factor design” or “limit states design” are beyond the scope of this specification.  
1.6 Quality control requirements are outside the scope of this Specification.  
1.7 The performance of a rim board product will be affected by the constituent wood species, geometry, adhesive, and production parameters. Therefore, rim board products produced by each individual manufacturer shall be evaluated to determine their product properties, regardless of the similarity in characteristics to products produced by other manufacturers.  
1.8 Where a manufacturer produces product in more than one facility, each production facility shall be evaluated independently. For additional production facilities, any revisions to the full qualification program in accordance with this specification shall be approved by an accredited, independent qualifying agency.  
1.9 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.10 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.  
1.11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practice for Thermographic Inspection of Insulation Installations in Envelope Cavities of Frame Buildings

SIGNIFICANCE AND USE
5.1 Although infrared imaging systems have the potential to determine many factors concerning the thermal performance of a wall, roof, floor, or ceiling, the emphasis in this practice is on determining whether insulation is missing or whether an insulation installation is malfunctioning. Anomalous thermal images from other apparent causes are not required to be recorded; however, if recorded as supplemental information, their interpretation is capable of requiring procedures and techniques not presented in this practice.
SCOPE
1.1 This practice is a guide to the proper use of infrared imaging systems for conducting qualitative thermal inspections of building walls, ceilings, roofs, and floors, framed in wood or metal, that contain insulation in the spaces between framing members. This procedure allows the detection of cavities where insulation is inadequate or missing and allows identification of areas with apparently adequate insulation.  
1.2 This practice offers reliable means for detecting suspected missing insulation. It also offers the possibility of detecting partial-thickness insulation, improperly installed insulation, or insulation damaged in service. Proof of missing insulation or a malfunctioning envelope requires independent validation. Validation techniques, such as visual inspection or in-situ R-value measurement, are beyond the scope of this practice.  
1.3 This practice is limited to frame construction even though thermography is used on all building types. (ISO 6781)  
1.4 Instrumentation and calibration required under a variety of environmental conditions are described. Instrumentation requirements and measurement procedures are considered for inspections from both inside and outside the structure. Each vantage point offers visual access to areas hidden from the other side.  
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Note 1 and Note 3.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
