ASTM D3930-08(2023) PDF

Overview

ASTM D3930-08(2023) is the internationally recognized standard specification for adhesives used in the construction of manufactured homes, specifically for structural or semi-structural wood-to-wood bonding. Developed by ASTM International, this standard provides comprehensive criteria to measure and evaluate the performance of adhesives when used on a variety of wood-based materials such as lumber, plywood, particleboard, gypsum board, and other wood-surfaced substrates at the bondline. The standard addresses requirements for adhesives within the unique context and demanding conditions encountered in manufactured housing construction, focusing on long-term durability, safety, and performance.

Key Topics

• Scope and Classification

  • Applies to adhesives for structural and semi-structural wood-to-wood joints in manufactured homes.
  • Covers lumber, plywood, particleboard, gypsum board, and other wood-surfaced materials.
  • Does not cover adhesives for nonstructural uses (e.g., carpets, tiles, fixtures).
  • Adhesives are grouped by:
    • Resistance to deformation:
      • Group A (Structural)
      • Group B (Semistructural)
    • Resistance to moisture:
      • Type 1: Interior/exterior use (high moisture resistance)
      • Type 2: Weather-protected interior (moderate resistance)
      • Type 3: Interior use only (basic resistance)
    • Gap-filling ability (G/F designation)

• Performance Evaluation

  • Eleven test methods evaluate key adhesive properties:
    • Shear strength
    • Gap-filling ability (thick joint performance)
    • Resistance to deformation (creep)
    • Durability under exposure to adverse moisture and temperature
    • High- and low-temperature resistance
    • Moisture resistance (various exposure cycles)
    • Oxidation and aging resistance
    • Mold resistance

• Testing Approach

  • Many tests align with established ASTM procedures, ensuring international acceptance.
  • Test results help engineers select adhesives that match application-specific performance requirements.

Applications

• Manufactured Homes Construction
  • Ensuring strong, durable structural joints in frames, panels, flooring, and roof assemblies.
  • Selection of adhesives that withstand rigorous environments including variable humidity, temperature swings, and potential wet exposures.
• Design Engineer Decision-Making
  • Test data provided by this standard enables design engineers to specify adhesives based on robust performance metrics relevant to manufactured home environments.
  • Ensures quality control during factory production and after transit and installation.
• Quality Assurance and Procurement
  • Manufacturers and purchasers can use ASTM D3930 to certify product conformance and address any non-compliance through clear retesting and rejection provisions.
  • Standardized sampling and documentation support batch verification and consistent adhesive application.
