(Practice)Standard Practice for Periodically Measuring and Monitoring Sealant Dimensions to Stability Following a Period of Compression or Tension
Standard Practice for Periodically Measuring and Monitoring Sealant Dimensions to Stability Following a Period of Compression or Tension
SIGNIFICANCE AND USE
5.1 Many sealants have been observed to dimensionally change following a period of compression or tension, such as occurs during exposure in accordance with Practice C1589. It has been shown that for some sealants, increasing exposure to weathering increases the time required for dimensional stability and decreases the magnitude of dimensional change. Dimensional stability and knowledge of the stable sealant dimensions are critical to the accurate measurement of the sealant’s modulus by a test such as Test Method C1735.
5.2 This practice will find application in improving the accuracy of the modulus determined by a standard such as Test Method C1735 by using the accurate dimensions determined by this practice after stability is attained.
SCOPE
1.1 This practice covers a procedure for measuring and monitoring the physical dimensions of an elastomeric joint sealant in a test specimen configuration described in Test Method C719 following a period of compression or tension. These sealant materials are typically highly filled elastic materials. The dimensional change of these sealant materials is determined by measuring the dimensions at specific intervals over a period of time.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
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 C1815-17(2021) is the internationally recognized standard practice for periodically measuring and monitoring the physical dimensions of elastomeric joint sealants after they have been subjected to compression or tension. Developed by ASTM International, this standard outlines reliable procedures for determining the dimensional stability of sealant materials commonly used in construction and building applications. Accurate measurement of sealant dimensions over time is critical to evaluating their performance, particularly when determining properties such as modulus in accordance with related test methods.
Dimensional stability under movement and weathering conditions helps ensure that joint sealants maintain their integrity and effectiveness. By following ASTM C1815, organizations can enhance the reliability of sealant performance assessments and generate more accurate test data.
Key Topics
- Sealant Dimensional Monitoring: Guides users through the steps for periodic measurement of sealant dimensions, especially after exposure to compression or tension, as described in ASTM C719.
- Stability Assessment: Provides methods to establish stable dimensions after the sealant has recovered from being stretched or compressed, a crucial step before modulus testing.
- Measurement Procedure: Employs precise tools like micrometers or digital calipers to achieve high-accuracy thickness, width, and height readings.
- Environmental Conditions: Emphasizes the need to document temperature, humidity, and other environmental factors during testing.
- Reporting Requirements: Specifies detailed reporting, including sealant identification, substrate details, measurement conditions, number of specimens, and dimensional changes over time.
Applications
ASTM C1815 is essential for:
- Construction Material Testing: Used by laboratories and manufacturers to assess the long-term stability of elastomeric joint sealants under real-world conditions.
- Sealant Modulus Determination: Supplies the necessary stable dimensional data required for accurate sealant modulus measurement per ASTM C1735.
- Product Development and Quality Control: Assists manufacturers in verifying the performance characteristics of new or existing sealant formulations after mechanical stress.
- Verification of Weathering Effects: Supports studies into how weathering, such as outdoor exposure per ASTM C1589, influences the dimensional recovery and stability of building sealants.
- Building Envelope Performance: Used to confirm that sealant joints in exterior applications retain their protective function after physical stresses.

Practical Value
Implementing ASTM C1815 improves the accuracy and credibility of sealant performance evaluations:
- Enables robust quality assurance and compliance for construction projects
- Informs material selection and maintenance planning for building envelopes
- Provides test laboratories with standardized methods for consistent, repeatable results
- Facilitates product development and benchmarking in the sealant industry
Adopting this ASTM sealant measurement standard ensures that sealant behavior-especially dimensional stability after tension or compression-is clearly understood, ultimately supporting safer and more durable building practices.
