Scope:

The ASTM D3310 test method is used to determine adhesive materials’ corrosivity. This test method is a subjective test as the determination of the degree of corrosivity is based upon a visual inspection for a green discoloration or other evidence of corrosion. In the adhesive bonding process, the hydrolytic stability or corrosivity is of significant importance in achieving acceptable joint durability. The ASTM D3310 test method has also been demonstrated to have protective characteristics and display corrosion activity, enhancing the adhesive joints’ long-term strength and endurance.

Test procedure:

The metal of interest is encased in a glass container with the adhesive substance for the ASTM D3310. The containers are kept at varying temperatures in temperature-controlled ovens, both with and without water. The glass jars containing the same metal samples (strips) with and without water but no adhesives are then stored in the same oven for comparison.

Specimen size:

The ASTM D3310 test protocol uses 5 to 10 grams of adhesives with the metal being examined as a test specimen.

Data:

Storage period, temperature, and corrosion degree are all recorded in accordance with ASTM D3310.If the corrosion is severe and quick, the first report could come in as soon as one hour. Otherwise, after 1, 3, and 7 days, observations can be made and recorded.

Conclusion:

The ASTM D3310 test method is used to determine adhesive materials’ corrosivity. This test method is a subjective test as the determination of the degree of corrosivity is based upon a visual inspection for a green discoloration or other evidence of corrosion.
