Standard Specification for Adhesives for Wood-Based Materials for Construction of Manufactured Homes

Standard Specification for Adhesives for Wood-Based Materials for Construction of Manufactured Homes

ABSTRACT
This specification provides the means to measure and evaluate the performance of adhesives for structural or semistructural bonding of wood-to-wood in manufactured homes. Wood as used in this specification includes lumber, plywood, particleboard, gypsum board, and all materials having woodbased surfaces at the bondline. The adhesives can be classified according to resistance to deformation: Group A or structural, and Group B or semistructural. Also, the adhesives may be designated into three types, according to their recommended use based on their resistance to water and water vapor: Type 1 for interior and exterior use, Type 2 for weather-protected interior use, and Type 3 for interior use only. Different tests shall be performed in order to determine the following properties of adhesives: shear strength, gap-filling ability, total deformation resistance, moisture and temperature limitation during fabrication, high-temperature resistance, low-temperature resistance, moisture resistance, aging, oxidation resistance, and mold resistance.
SCOPE
1.1 This specification provides the means to measure and evaluate the performance of adhesives for structural or semi-structural bonding of wood-to-wood in manufactured homes. Wood as used in this specification includes lumber, plywood, particleboard, gypsum board, and all materials having wood-based surfaces at the bondline.

Standard Specification for
Adhesives for Wood-Based Materials for Construction of
1
Manufactured Homes
This standard is issued under the fixed designation D3930; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
This specification provides a standard for measuring and evaluating the performance of adhesives
that will be used in joints of wood-based materials in constructing manufactured homes. This
specification has two parts: Part I contains the requirements necessary for an adhesive to conform to
this specification; and Part II provides test methods by which the performance of the adhesives will
be measured. A classification system is provided that groups adhesives according to resistance to
deformation under load, resistance to moisture, and gap-filling ability. Minimum test values have been
specified for certain properties of durability, while other property requirements are left open-ended.
The test methods used to obtain these values reflect adverse exposure and stress conditions that exist
during the construction, transit, and use of manufactured homes. By using values published from these
prescribed test methods, the design engineer can select an adhesive that best meets the requirements
of a specific adhesive application.
The test methods used in this specification were developed predominantly from existing ASTM
standards, while others came from standards that have been generally accepted for years. Some test
methods were more recently developed. In most instances, only parts of these standards have been
used in this specification. Since no precision and bias statements are available from the original test
methods, none can be made for this specification at this time.

ASTM D4680-98(2023)(Test Method)
Standard Test Method for Creep and Time to Failure of Adhesives in Static Shear by Compression Loading (Wood-to-Wood)

SIGNIFICANCE AND USE
4.1 Creep data that are obtained over a relatively short period of time in this test method can provide a measure of an adhesive bond's ability to withstand static loading in shear over a relatively long period of time. Creep measurements are made over a range of expected service conditions, including level of stress, temperature, relative humidity, and duration of load. Creep rate, creep strain, and creep modulus are calculated at the various service conditions.  
4.2 Creep data can be used to (1) predict performance of an adhesive under long-term loading, (2) characterize an adhesive, (3) compare adhesives with each other and against specifications, and (4) design structural members fabricated with an adhesive.  
4.3 Time-to-failure data provide a measure of the ultimate load-carrying ability of an adhesive bond as a function of time at various levels of stress, temperature, and relative humidity.  
4.4 With proper caution, time-to-failure data derived from relatively short loading periods can be extrapolated to estimate the useful service life of an adhesive at working levels of static stress. This property may also be used with creep data to accomplish purposes listed in 4.2.  
4.5 This test method is a research tool intended for development or evaluation of new adhesives and new product designs. The researcher may select from suggested tests those that are appropriate. However, creep and time-to-failure tests are nonroutine and can be time-consuming and expensive, so tests must be selected with care.  
4.6 The apparatus and procedures may be suitable for measuring creep properties of adhesives on substrates other than wood, such as metal, plastic, and glass, but such considerations are not within the scope of this test method.
SCOPE
1.1 This test method covers the determination of time-dependent properties of structural adhesives in wood-to-wood bonds when specimens are subjected to shearing stresses at various levels of static load, constant temperature, and relative humidity. Apparatus and procedures are provided for direct measurement of time-dependent shear deformation (creep) and time to failure of adhesive bonds under static load. Guidelines for selecting test conditions, methods for calculating creep rate, creep strain, creep modulus, and extrapolation of time to failure, are given along with methods of presenting these data.  
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 Guide for Classifying and Specifying Adhesives

SIGNIFICANCE AND USE
4.1 The purpose of this classification system is to provide a method of identifying adhesives in order to give industry a system that can be used universally for materials. It further provides a means for specifying these materials by the use of the standards that are developed using this guide.  
4.2 This classification system was developed to permit the addition of future adhesives.
SCOPE
1.1 This guide provides a classification system for tabulating the properties of adhesives suitable for holding parts or assemblies together. The use of this guide also provides information necessary for the development of standard specifications for adhesives.  
Note 1: This classification system may serve many of the needs of industries using adhesives. This guide is subject to revision as the need requires; therefore, the latest revision should always be used.  
1.2 Limitations—This classification system is intended to be a means of identifying adhesives. It is not intended for the selection of materials. Material selection should be made by those having expertise in the adhesives field after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the attachment process to be employed, the inherent properties of the material not covered in this document, and the economic factors.  
1.3 This classification system is based on the premise that adhesives can be arranged into broad generic families using basic properties to arrange the materials into groups, classes, and grades.  
1.4 In all cases where the provisions of this classification system would conflict with the referenced ASTM specification for a particular material, the latter shall take precedence.  
1.5 The values stated in SI units, as detailed in IEEE/ASTM SI 10, are to be regarded as the standard.  
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.
