ASTM D3930 – Standard Specification for Adhesives for Wood-Based Materials for Construction of Manufactured Homes
Description:
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.
1.1.1 The performance of the adhesives is measured in the following tests:
| Number | Test | Section |
| 1 | Low Temperature | 16 |
| 2 | Dry Lumber | 17 |
| 3 | Gap-Filling | 18 |
| 4 | High Temperature | 19 |
| 5 | Type 3 Qualification | 20 |
| 6 | Type 2 Qualification | 21 |
| 7 | Aging, Film Oxidation | 22 |
| 8 | Aging, Bond Oxidation | 23 |
| 9 | Resistance to Deformation, Creep | 24 |
| 10 | Mold | 25 |
| 11 | Type 1 Qualification | 26 |
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.
