ASTM D1489 Standard Test Method for Nonvolatile Content of Aqueous Adhesives 

Get Certified ASTM D1489 Testing for Reliable Adhesive Quality Assessment

Reliable ASTM D1489 (Standard Test Method for Nonvolatile Content of Aqueous Adhesives) testing helps manufacturers evaluate the solids content of their aqueous adhesive products in a standard testing environment. Laboratories also compare formulations and batches using the same methods. The test can help select materials when the manufacturer requires an adhesive with the correct solids content for a particular use. 

• Determines the nonvolatile content of aqueous adhesives.
• Applicable for glues like dextrin, starch, casein, and animal gelatine.
• Measures the solids level remaining after volatile components are removed.
• Supports comparison of the nonvolatile content of different adhesives.
• Assists laboratories in the evaluation of selection and uniformity of adhesives and products.
• Performs quality-control testing of adhesive (aqueous) products.
• Provides a standardized method for research and adhesive evaluation.
• Works with standard units (SI units).

What is ASTM D1489 Testing used for?

ASTM D1489 testing determines the nonvolatile content of aqueous adhesives. Manufacturers then use the results to compare adhesive formulations and test product uniformity. The test is also useful for quality-control programs and research in which uniform adhesive composition is desirable. This standard-

• Determines the nonvolatile content of aqueous adhesives.
• Tests dextrin, starch, casein, and animal gelatin adhesives.
• Assists with comparisons between nonvolatile components of various adhesive formulations.
• Aids in the assessment of uniformity of adhesive products.
• Assists manufacturers with quality-control testing.
• Supports research and development of formulations of aqueous adhesives.
• Gives quantitative results for evaluation of adhesives that do not require the destruction of the material being tested.
• Aids in the selection of adhesives where solid content plays a critical role. 

Which materials can be tested under ASTM D1489?

The standard ASTM D1489 covers dextrin, starch, casein, and animal gelatin adhesives. The method is for the determination of the material that remains after the removal of volatile materials under controlled conditions. In laboratories, the procedure is employed to test the quality of adhesive samples and to compare the nonvolatile content of adhesive samples in quality control and research. 

Why is ASTM D1489 Important?

ASTM D1489 provides a standardized method for determining the nonvolatile content of aqueous adhesives. Adhesive formulations vary in solids content, which can affect product uniformity, material comparison, and manufacturing quality. The test measures the material remaining after volatile components are removed under controlled drying conditions. The results assist manufacturers and laboratories in comparing adhesive formulations, evaluating product uniformity, and supporting quality-control and research activities. The method applies to aqueous adhesives such as dextrin, starch, casein, and animal gelatin.

ASTM D1489 Testing Process and Data Collection

An analyst takes a representative sample of the aqueous adhesive and thoroughly mixes it to achieve uniform consistency. The analyst then weighs about 10 g of the adhesive and scatters it in hot distilled water. The analyst transfers the prepared dispersion to a 200 mL volumetric flask and then transfers 10 mL of the dispersion into a prepared weighing bottle containing silica sand. The analyst dries the specimen at 105 ± 1 °C (221 ± 2 °F), cools it in a desiccator, and determines the final mass. Finally, the analyst calculates and records the nonvolatile content as a percentage for evaluation and reporting purposes.

Common Challenges and Troubleshooting

ASTM D1489 results are accurate when specimen preparation, test temperature, moisture conditions, and exposure or conditioning procedures specified in the test method are carefully monitored. Measurement results may vary depending on specimen thickness, surface, equipment settings, or environment. Before testing, the technician must inspect the testing equipment, measurement instrumentation, and specimen condition. Engineers obtain consistent and repeatable results if the same procedures are used to prepare, condition, test, and evaluate their specimens. 

• The laboratory reports the test duration and applicable test conditions, including time in hours (h) and temperature in degrees Celsius (°C).
• The analyst records the measured specimen characteristics using the applicable measurement techniques and reports each property in its specified unit, such as mm, %, or mass units, as applicable.
• The technician documents visible or physical changes that occur during testing, including discoloration, cracking, deformation, and surface deterioration, when applicable to the material.
• The laboratory compares the measured results among specimens or against reference conditions and reports the observed differences rather than assigning a single overall performance value to the material.
