D3930-08 – Standard Test Method Technical Guide
ASTM D3930-08 (Reapproved 2023) is a standard specification that provides a comprehensive framework for measuring and evaluating the performance of adhesives used in joints of wood-based materials for manufactured homes. This standard is divided into two integral parts: Part I details the requirements for adhesive conformity, while Part II presents the test methods for performance measurement. A unique classification system groups adhesives based on their resistance to deformation under load, resistance to moisture, and gap-filling ability, aiding design engineers in selecting appropriate adhesives for specific applications.
📋 Part I – Requirements and Classification
Part I of this specification outlines the necessary requirements for adhesives intended for structural or semi-structural bonding of wood-to-wood in manufactured homes. The term “wood” encompasses materials such as lumber, plywood, particleboard, and gypsum board with wood-based surfaces. Non-structural adhesives for carpet, floor tile, ceramic fixtures, and similar applications are not covered. The following table lists the 11 tests included for evaluating adhesive performance according to this specification:
| 🔢 Test Number | 🧪 Test Description | 📄 Section Reference |
|---|---|---|
| 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 |
These tests evaluate adhesive durability under adverse exposure and stress conditions during construction, transit, and use of manufactured homes. Minimum test values are specified for certain durability properties, while other requirements remain open-ended to allow flexibility for specific applications.
🔬 Part II – Test Methods and Performance Evaluation
Part II details the test methods used to measure adhesive performance, predominantly derived from existing ASTM standards. Tests assess temperature resistance, aging through oxidation, creep deformation, and mold growth, among others. For example, the Creep test (Section 24) measures resistance to deformation under sustained load, and the Low Temperature test (Section 16) evaluates behavior in cold conditions. The classification system groups adhesives by performance in these areas, supporting engineer selection.
💡 Tip: All measurements must adhere to the inch-pound unit system as stated in Section 1.2, with SI units provided for information only.
⚠️ Note: Since test methods are adapted from existing standards, no precision or bias statements are available. Users should establish safety and environmental practices per Section 1.3.
