Standard Test Method for Package Stability of Paint
ABSTRACT
This test method covers the procedures for testing the package stability of liquid paint by determining the change in consistency and certain other properties of the solvent- or water-reducible type paint when stored above a certain temperature. Test equipment include spatula, viscometer, paint brush, and test surface. Samples for testing should be collected from as received and stored samples. The samples must be observed for any skinning, corrosion, odor of putrefaction, rancidity, or souring, lower layer rigidity, consistency, and the presence of lump or streaks in the brushed films.
SCOPE
1.1 This test method covers the change in consistency and certain other properties that may take place when liquid paint of either the solvent-reducible or water-reducible type is stored at a temperature above 0 °C (32 °F).
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM D1849-95(2019) - Standard Test Method for Package Stability of Paint is an internationally recognized test method developed by ASTM International. This standard specifies procedures for evaluating the package stability of liquid paints, including both solvent-reducible and water-reducible types, when stored above freezing temperatures. The method focuses on assessing changes in paint consistency and the development of defects such as skinning, corrosion, spoilage odors, and physical changes after storage. It is widely used by paint manufacturers, quality assurance professionals, and laboratories to ensure the shelf life and usability of packaged paints.
Key Topics
- Package Stability Testing: Procedures for testing the stability of paint in its original packaging, simulating conditions of storage and transportation.
- Storage Conditions: Evaluation of paint samples stored above 0°C (32°F) to monitor changes over time.
- Test Equipment: Utilizes a spatula, Stormer-type viscometer, paint brush, and impervious test surface designed for repeatable and consistent results.
- Physical Observations and Measurements: Examines skinning, pressure, odor, corrosion, consistency, lower layer rigidity, and the presence of lumps or streaks in brushed paint films.
- Reporting Guidelines: Specifies the documentation of storage duration, temperature, sample weights, and qualitative ratings for observed defects.
Applications
The ASTM D1849-95(2019) test method provides practical, actionable guidance for:
- Paint Manufacturers: Ensuring that batches of solvent- and water-reducible paints maintain their quality during storage and remain fit for application after prolonged periods.
- Quality Control: Allowing quality assurance teams to monitor key characteristics such as viscosity, spoilage, and surface defects, which directly impact product performance and customer satisfaction.
- Product Development: Supporting research and development teams in evaluating new formulations and optimizing shelf life by testing package stability under accelerated storage conditions.
- Compliance and Procurement: Serving as a benchmark for compliance in contracts and procurement specifications, particularly where storage and transport stability are critical.
By following this standard, organizations can proactively address potential quality issues, prevent costly product recalls, and provide evidence of conformance with internationally recognized best practices.
