Standard Specification for Establishing and Monitoring Structural Capacities of Prefabricated Wood I-Joists

Standard Specification for Establishing and Monitoring Structural Capacities of Prefabricated Wood I-Joists

ABSTRACT
This specification gives procedures for establishing, monitoring, and reevaluating structural capacities of prefabricated wood I-joists. Capacities considered are shear, moment, and stiffness. Procedures for establishing common details are given and certain design considerations specific to wood I-joists are itemized. Qualification is required for certain common details of I-joist application since they often influence structural capacities. All capacities are to be reported with three significant digits. Shear capacity qualification, moment capacity qualification, end joint qualification, stiffness capacity and creep qualification, and details of end use shall be established to meet the requirements prescribed. Design values are determined from the analysis and capacities as specified. The bearing capacity and regarded solid sawn lumber flanges shall be reevaluated to meet the requirements prescribed. The shear and flange material, and empirical moment capacity shall be tested to meet the requirements prescribed.
SCOPE
1.1 General—This specification gives procedures for establishing, monitoring, and reevaluating structural capacities of prefabricated wood I-joists. Capacities considered are shear, reaction, moment, and stiffness. Procedures for establishing common details are given and certain design considerations specific to wood I-joists are itemized.
1.2 Contents of the Standard—An index and brief description of the main features of this specification are given in X1.1.1.
1.3 Development of the Standard—The development and intent of this specification is discussed in Appendix X1.
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 and health practices and determine the applicability of regulatory limitations prior to use. A specific precautionary statement is given in 6.1.1.5.

Standard Specification for Round Wood Dowels (Pegs) for Use in Wood Construction

ABSTRACT
This specification covers the dimensions and materials for the manufacture of round wood dowels (pegs) used in the fabrication of connections in wood construction. The round wood dowels shall have diameters from 1/2 in. (12.5 mm) to 2 in. (51 mm). Diameters shall not be more than 2% oversize, nor less than 1% undersize, and shall not vary, along a wood dowel length (other than deliberate chamfer) more than 1%. Wood dowels shall be fabricated to ensure that the wood fibers are aligned with the longitudinal axis of the dowel. They shall be fabricated from any species of wood that has an oven dry specific gravity of at least 0.57; from wood that has been air-dried or kiln-dried to approximately constant weight before fabrication; and from clear, straight-grained timber free from any form of decay. Furthermore, wood dowels shall be protected with a treatment of paraffin wax, or similar sealing substance capable of inhibiting the absorption of moisture from the atmosphere.
SCOPE
1.1 This specification covers standardizing the dimensions and materials for the manufacture of round wood dowels (pegs) used in the fabrication of connections in wood construction. The referencing of this specification in design, construction, and purchase order documents is intended to provide some assurance that the round wood dowels to be used in an assembly meet minimum materials-quality standards and that dimensions for fabrication and finish can be relied on to ensure connection performance. This specification provides regulatory agencies with a set of standards by which to judge the acceptability of round wood dowels encountered in the field and in fabricators’ shops.  
1.2 This specification only addresses the standardization and manufacture of round wood dowels. Other types of wood dowels, such as sawn or cleaved pegs, are outside the scope of this specification.  
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 Safety Hazards—There are no known hazards with the use of this specification. The products manufactured to this specification should not be brittle or difficult to install with proper tools.  
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.

Standard Specification for Evaluation of Duration of Load and Creep Effects of Wood and Wood-Based Products

ABSTRACT
This specification covers the procedure for testing and evaluating duration of load and creep effects of wood and wood-based materials relative to an accepted duration of load adjustment model. This specification is proposed for use for products that are covered by a consensus standard such as lumber, structural composite lumber and structural use panels. The procedure covered in this specification, however, is not intended to evaluate performance of products under impact loading.
SCOPE
1.1 This specification provides a procedure for testing and evaluating duration of load and creep effects of wood and wood-based materials relative to an accepted duration of load adjustment model. This specification was created for products that are currently covered by a consensus standard (for example, lumber, structural composite lumber, and structural-use panels). This procedure is intended to demonstrate the engineering equivalence to the duration of load and creep effects of visually graded lumber as specified in Practice D245 for a product under evaluation used in dry service conditions. This procedure is not intended to evaluate the performance of products under impact loading. Quantification of specific duration of load or creep factors is beyond the scope of this specification. For further guidance regarding the applicability of this specification refer to X1.1 in the Commentary.  
1.2 Use of the procedure in this specification to determine equivalence to the Practice D245 duration of load relationship is limited to solid wood and wood-based products whose long term load behavior is similar to that of solid wood. Equivalence demonstrated in this specification is dependent upon evaluation of a product's 90-day (minimum) creep-rupture performance. In this evaluation, three criteria must be satisfied: (1) adequate strength over a 90-day period, (2) decreasing creep rate, and (3) limited fractional deflection. A summary of the development of these criteria and the underlying assumptions behind them is provided in the Commentary in Appendix X1 and Appendix X2.  
1.3 Long term degradation phenomena not described by a creep-rupture model are not addressed in this specification (see Commentary X1.2.4).  
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 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 Test Methods for Simulated Service Testing of Wood and Wood-Based Finish Flooring

SIGNIFICANCE AND USE
3.1 The test methods presented herein are intended to provide both a factual and comparative means of appraising the suitability of finish flooring. The procedures developed simulate some conditions of use that may require either maintenance beyond that considered normal or replacement of the floor surface material.  
3.2 It is important for some of the evaluations that the substrate to be used beneath the finish flooring be duplicated because the type and degree of support will have a direct influence on the value obtained from test. For example, in some present-day construction, low-density materials are used for sound-deadening immediately below the finish flooring. The way this substrate distributes loading and absorbs energy will have an influence on evaluations such as those in rolling and concentrated loads.  
3.3 The test methods presented herein may be used to compare different finish floorings as to their resistance to severe and ordinary service loads and also may serve as the means to set specification limits. The properties obtained by these test methods are needed in addition to such basic material properties as stiffness, strength, hardness, and dimensional stability.  
3.4 All tests may not be required for any specific investigation. There may be an interrelation between two tests, and when it has been demonstrated what the interrelation is, a complete evaluation is only required as a final stage of a study. In each instance, therefore, it is necessary to determine which evaluations shall be made to fulfill the objectives.
SCOPE
1.1 These test methods cover procedures for measuring the performance of finish flooring under the following service loadings and conditions:

Standard Specification for Establishing Performance Ratings for Wood-Plastic Composite and Plastic Lumber Deck Boards, Stair Treads, Guards, and Handrails

ABSTRACT
This specification presents the standard procedures for establishing the performance rating of wood-plastic composite (WPC) deck boards and guardrail systems (guards or handrails). The purpose of this specification is to establish the basis for code recognition of these products or systems in exterior applications where combustible construction is allowed. The general requirements foe these products shall be dictated by their performance in the following test methods: flesural tests; temperature and moisture effects; ultraviolet resistance test; freeze-thaw resistance test; biodeterioration tests; and fire performance tests. Deck boards shall additionally examined by: creep-recovery test; determination of unadjusted allowable load; mechanical fastener holding tests; and slip resistance test. In the same manner, guards and handrails shall additionally be analyzed through concentrated load tests, and one- and two-family dwelling requirements.
SCOPE
1.1 This specification covers procedures to establish a performance rating for wood-plastic composite and plastic lumber for use as exterior deck boards, stair treads, guards, and handrails. The purpose of this specification is to establish a basis for code recognition of these products or systems in exterior applications.
Note 1: While wood-plastic composites contain wood or other cellulosic materials, the presence of wood or other cellulosic materials in plastic lumber is not required by this specification. Due to non-wood materials in wood-plastic composites and plastic lumber the structural, physical, fire, and other attributes may not be similar to those of wood.
Note 2: The products addressed in this standard are considered combustible. No fire response characteristic is required in this specification except for flame spread index as determined in accordance with Test Method E84.  
1.1.1 The plastic component of wood-plastic composites and plastic lumber covered by this specification shall consist primarily of thermoplastics.  
1.2 Deck boards, stair treads, guards, and handrails covered by this specification are permitted to be of any code compliant shape and thickness (solid or non-solid).  
1.3 Wood-plastic composites and plastic lumber are produced in a broad range of fiber and/or resin formulations. It is recognized that the performance requirements in this specification are valid for any material or combination of materials used as deck boards, stair treads, guards, or handrails.  
1.4 Details of manufacturing processes are beyond the scope of this specification.  
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.

Standard Practice for Calculating the Superimposed Load on Wood-frame Floor-Ceiling Assemblies for Standard Fire-Resistance Tests

SIGNIFICANCE AND USE
4.1 Test Methods E119, E1529, and other standard fire resistance test methods specify that throughout the fire-resistance test, a constant superimposed load shall be applied to a load-bearing test specimen to simulate a maximum allowable load condition. This superimposed load shall be the maximum load allowed by design under nationally recognized structural design criteria for the tested floor configuration (that is, joist selection, spacing, and span).  
4.1.1 For this practice, the nationally recognized structural design criteria to be used to determine the maximum load condition are those for the allowable stress design (ASD) method in the NDS (National Design Specification for Wood Construction).
Note 1: The NDS should be used to ensure calculation of the superimposed load is in compliance with all applicable provisions of that standard. Appendix X1 describes how to calculate the superimposed load in accordance with the NDS.  
4.1.2 Alternatively, the standard fire resistance test methods shall be permitted to be conducted by applying a load less than the maximum allowable load in 4.1.1 for the tested configuration; however, these tests shall be identified in the test report as being conducted under restricted loading conditions.  
4.2 This practice describes procedures for calculating the superimposed load to be applied in standard fire resistance tests of wood floor-ceiling assemblies. Practice D6513 provides a similar methodology for calculating the superimposed load on wood-frame walls.  
4.3 Statements in either the fire resistance test method standard or the nationally recognized structural design standard supersede any procedures described by this practice.
SCOPE
1.1 This practice covers procedures for calculating the superimposed load required to be applied to load-bearing wood-frame floor-ceiling assemblies throughout standard fire-resistance tests.  
1.2 These calculations determine the maximum superimposed load to be applied to the floor-ceiling assembly during the fire resistance test. The maximum superimposed load, calculated in accordance with nationally-recognized structural design criteria, shall be designed to induce the maximum allowable stress in the wood floor-ceiling fire test configuration being tested.  
1.3 This practice is only applicable to those wood-frame floor-ceiling assemblies for which the nationally recognized structural design criteria are contained in the National Design Specification for Wood Construction (NDS).  
1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

Standard Practice for Field Calibration and Application of Hand-Held Moisture Meters

SIGNIFICANCE AND USE
4.1 Hand-held meters provide a rapid means of sampling moisture content of wood-based materials during and after processing to maintain quality assurance and compliance with standards. However, these measurements are inferential; that is, electrical parameters are measured and compared against a calibration to obtain an indirect measure of moisture content. The electrical measurements are influenced by actual moisture content, a number of other wood variables, environmental conditions, geometry of the measuring probe circuitry, and design of the meter. The maximum accuracy can only be obtained by an awareness of the effect of each parameter on the meter output and correction of readings as specified by these test methods. Appendix X1 is a commentary that provides explanation of the mandatory sections and discussion of historical practices. Appendix X2 addresses the influence of process and wood variables.  
4.1.1 This practice provides for calibration and application of wood products that contain commercial characteristics and that reflect the manufacturing environment.  
4.2 Most uses of hand-held moisture meters employ correlative (predictive) relationships between the meter reading and wood areas or volumes that exceed that of the direct meter measurement (for example, larger specimens, pieces of lumber, lots). The field calibration section of this practice anticipates the potential need for this type of sampling. These correlative uses are examined in Appendix X3.
SCOPE
1.1 This practice applies to the measurement of moisture content of solid wood, including solid wood products containing additives, that is, chemicals or adhesives, by hand-held moisture meters under conditions of end-use.  
1.1.1 This practice includes calibration, use, and interpretation of meters for conditions that relate to wood product characteristics, such as nonuniform grain and growth ring orientation, and to end-use process conditions, such as moisture gradients.  
1.1.2 Meters employing differing technologies will not necessarily provide equivalent readings under the same conditions. When this practice has been applied, it is assumed that the referenced meter is acceptable unless otherwise specified. Meters shall have been calibrated by Test Methods D4444.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 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 Test Methods for Evaluating Side-Bonding Potential of Wood Coatings

SIGNIFICANCE AND USE
4.1 This test method was originally designed as a means of quantitatively measuring the level of adhesion of the wood-wood interface caused by a wood coatings system applied to the substrate. The tensile test is useful in measuring bonding strength of coatings, such as gymnasium coatings, in which the wood strip flooring primarily expands or contracts in response to changes across the cross-sectional width of the strip floor.  
4.2 This test method was further designed as a means of measuring the side-bonding potential of wood coating systems.
SCOPE
1.1 These test methods describe an evaluation procedure for the determination of undesirable side-bonding of coatings for wood flooring. They provide two mechanical properties tests for the quantitative determination of the cohesive strength of wood coatings (tensile and lap shear).  
1.2 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.  
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 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 Specification for Establishing and Monitoring Structural Capacities of Prefabricated Wood I-Joists

ABSTRACT
This specification gives procedures for establishing, monitoring, and reevaluating structural capacities of prefabricated wood I-joists. Capacities considered are shear, moment, and stiffness. Procedures for establishing common details are given and certain design considerations specific to wood I-joists are itemized. Qualification is required for certain common details of I-joist application since they often influence structural capacities. All capacities are to be reported with three significant digits. Shear capacity qualification, moment capacity qualification, end joint qualification, stiffness capacity and creep qualification, and details of end use shall be established to meet the requirements prescribed. Design values are determined from the analysis and capacities as specified. The bearing capacity and regarded solid sawn lumber flanges shall be reevaluated to meet the requirements prescribed. The shear and flange material, and empirical moment capacity shall be tested to meet the requirements prescribed.
