ASTM D3310-00(2023) PDF

Overview

ASTM D3310-00(2023), Standard Test Method for Determining Corrosivity of Adhesive Materials, is an international standard developed by ASTM International. This test method provides procedures to evaluate whether cured or uncured adhesive materials are corrosive to metals. The method uses direct visual inspection for signs of corrosion, such as green discoloration or other visible evidence, making it primarily a screening tool.

Compliance with ASTM D3310 is important for manufacturers and users of adhesives in industries where metal components may be exposed to adhesive materials. The standard supports product development, quality control, and regulatory compliance by identifying adhesives that may lead to unacceptable corrosion of metals.

Key Topics

• Corrosivity Assessment: The test method determines if adhesive materials, in either cured or uncured states, are potentially corrosive to metals.
• Subjective Evaluation: The degree of corrosion is determined by visual comparison of test specimens to control samples, focusing on discoloration or visible corrosion evidence.
• Testing Apparatus:
  • Wide-mouth glass jars with TFE- or FEP-fluorocarbon cap liners.
  • Forced draft circulating air ovens for controlled temperature exposure.
  • Metal strips (of interest to the application) abraded to a shiny finish.
• Test Procedure Highlights:
  • Metal samples are partially embedded in adhesive within the jar.
  • Samples are exposed to specific temperatures, both with and without water presence.
  • Control samples without adhesives are run simultaneously for comparison.
• Observation and Reporting:
  • Corrosion is rated on a five-point scale ranging from "less tarnished than control" to "badly corroded."
  • Reports include adhesive and metal identification, exposure conditions, storage parameters, and detailed observations.

Applications

ASTM D3310 is widely used in various industries where adhesives are in contact with metal substrates. Its applications include:

• Product Development: Ensures that new adhesive formulations are not corrosive to intended metal substrates.
• Quality Assurance: Serves as a routine screening test for incoming materials or batches during manufacturing.
• Material Selection: Assists engineers and designers in selecting adhesives suitable for use with specific metal alloys, reducing corrosion risks.
• Regulatory and Safety Compliance: Supports documentation for regulatory approvals where material compatibility and corrosion resistance are required.
• Packaging and Electronics: Useful for verifying suitability of adhesives in electronic components and packaging that use metal contacts or enclosures.
