INTRODUCTION
The purpose of this test method is to provide for the determination of the resistance-to-peel strength
of adhesives when surfaces joined by an adhesive are separated by applying a force to one of the
surfaces at a 90 degree angle. The accuracy of the results of strength tests of adhesive bonds will
depend on the conditions under which the bonding process is carried out. Unless otherwise agreed
upon between the manufacturer and the purchaser, the bonding conditions shall be prescribed by the
manufacturer of the adhesive. In order to ensure that complete information is available to the
individual conducting the tests, the manufacturer of the adhesive shall furnish numerical values and
other specific information for each of the following variables:
(1) Procedure for preparation of the surfaces prior to application of the surfaces prior to application
of the adhesive, the cleaning and drying of surfaces, and special surface treatments, which are not
specifically limited by the pertinent test method.
(2) Complete mixing directions for the adhesive.
(3) Conditions for the application of the adhesive, including the rate of spread or thickness of the
film, number of coats to be applied, whether to one or both of the surfaces, and the conditions of
drying.
(4)Assembly conditions before the application of pressure, including room temperature and length
of time.
(5) Curing conditions, including the amount of pressure to be applied, the length of time under
pressure, and the temperature of the assembly when under pressure. It should be stated whether this
temperature is that of the glue line or of the atmosphere at which the assembly is to be maintained.

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. This specification does not cover other adhesives used in manufactured homes such as adhesives for carpet, floor tile, ceramic fixtures, plastic laminates, trim and millwork, and similar nonstructural applications.

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.
