ASTM C1183/C1183M-13(2018)

Standard Test Method for Extrusion Rate of Elastomeric Sealants

SIGNIFICANCE AND USE
4.1 Sealants are supplied with various rheological properties ranging from pourable liquids to nonsagging pastes. Single-component sealants are supplied ready for use upon opening the container. Multicomponent sealants are supplied as a base component(s) and a curing agent separately packaged. After mixing the two or more parts, the sealant is ready for application. This test method is intended to provide a means to measure the extrusion rate spanning the range of rheological properties.  
4.2 This test method also covers the option of measuring the freeze-thaw and heat stability of such sealants.  
4.3 This test method provides for an option of either a metal or plastic nozzle. It is intended that the metal nozzle be used when greater precision is required, such as in ASTM specifications. The plastic nozzle may be used for general screening of sealant properties or for developmental purposes when a large number of test specimens are being tested.  
4.4 This test method measures the volume of sealant extruded over a given period of time at a given pressure (kPa or psi).
SCOPE
1.1 This test method covers two laboratory procedures for determining the extrusion rate of elastomeric sealants for use in building construction.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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 There is no known ISO equivalent to this test method.  
1.5 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 C1183/C1183M-13(2018) is the internationally recognized standard test method for determining the extrusion rate of elastomeric sealants. Developed and maintained by ASTM International, this standard specifies laboratory procedures that measure the rate at which different sealant materials - ranging from pourable liquids to non-sagging pastes - are extruded under controlled conditions. Its primary purpose is to help manufacturers, quality engineers, and construction professionals assess the consistency and application properties of building sealants used in construction and infrastructure projects.

This standard outlines procedures for both single-component and multicomponent elastomeric sealants and accommodates their broad range of rheological (flow) characteristics. By providing a reliable evaluation method, ASTM C1183/C1183M supports performance verification and quality control for sealants critical to building envelope integrity.

Key Topics

• Sealant Types: Single-component and multicomponent (mixed just before application) elastomeric sealants, including latex-based and non-sag formulas.
• Testing Procedures: Two distinct laboratory procedures for measuring sealant extrusion rates.
• Nozzle Options: Use of metal nozzles for precision testing, and plastic nozzles for routine screening or developmental testing with large sample sets.
• Measurement Parameters: Quantification of the volume of sealant extruded over a defined time at a specified air pressure.
• Rheological Range: Adaptability to sealants from highly fluid to very viscous.
• Stability Testing: Optional procedures for freeze-thaw and heat stability evaluations, simulating real-world storage and service conditions.
• Reporting Requirements: Detailed recordkeeping for trade names, test conditions, procedure type, specific gravity, nozzle used, and any deviations.

Applications

ASTM C1183/C1183M-13(2018) is widely utilized in the construction, infrastructure, and sealant manufacturing industries. It offers practical benefits in areas such as:

• Product Development: Enables manufacturers to develop and compare new sealant formulations by monitoring extrusion rates under standardized conditions.
• Quality Control: Supports in-process and finished product assessment, ensuring batch-to-batch consistency of elastomeric and latex sealants.
• Specification Compliance: Assists producers and buyers in verifying that sealants meet contractual or regulatory requirements for extrusion and application performance.
• Installation Assurance: Helps construction professionals select sealants with appropriate rheological properties to match specific project needs.
• Research and Testing Laboratories: Used as a benchmark method for comparative analysis and certification testing of sealant extrusion properties.

Currently, there is no recognized ISO equivalent to ASTM C1183/C1183M, highlighting its unique role in the assessment of elastomeric sealant extrusion rates for the building and construction industry.

Professionals seeking excellence in sealant application, performance, and consistency rely on ASTM C1183/C1183M as a cornerstone for product testing, industry compliance, and project specification. Utilizing this standard helps ensure high-quality building seals, enhancing durability and performance of the built environment.

sure all of the material that has exited the end of the nozzle is

7.7 Weigh the container to the nearest 0.1 g and subtract the
initial weight, to obtain the weight of the extruded sealant.
Convert the weight of the sealant to volume of sealant by
dividing the weight by the specific gravity. If all the material is
extruded in less than 60 s, note the length of time required and
