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 an internationally recognized standard test method developed by ASTM International for determining the extrusion rate of elastomeric sealants used in building construction. This method covers laboratory procedures designed to evaluate how these sealants flow or are dispensed under specified conditions, which is crucial for assessing their suitability and performance in various construction applications. The standard accommodates a wide range of rheological properties, from pourable liquids to nonsagging pastes, and applies to both single- and multicomponent sealants.

Key Topics

• Elastomeric Sealants: Includes both single-component (ready-to-use) and multicomponent (base and curing agent mixed prior to use) formulations.
• Extrusion Rate Measurement: The primary focus, assessing the volume of sealant extruded in a set period under standardized pressure (measured in kPa or psi).
• Rheological Range: Covers varying consistencies, from liquids to pastes.
• Precision Options:
  • Metal Nozzle: Provides higher precision, suitable for compliance with other ASTM specifications.
  • Plastic Nozzle: Used for general screening or when high testing volume is required.
• Stability Assessment: Offers procedures to test freeze-thaw and heat stability, ensuring sealants can withstand environmental stress.
• Reporting Requirements:
  • Trade name and identification of the sealant
  • Description of used test procedure and specific conditions
  • Type of nozzle used and other variations from standard method
  • For multicomponent products, details on mixing and timing

Applications

The ASTM C1183/C1183M standard is vital for quality assurance and performance verification in the construction industry, especially when selecting or approving elastomeric sealants for building sealing and jointing. Practical applications include:

• Product Development: Manufacturers rely on this standard to benchmark extrusion performance during research and formulation improvements.
• Quality Control: Production batches can be validated for consistent extrusion characteristics, essential for both automated and manual application processes.
• Specification Compliance: Ensures delivered sealants meet project and regulatory specifications related to workability and extrusion qualities.
• Performance Testing: Evaluates sealant performance after exposure to temperature extremes (freeze-thaw and elevated heat stability) which is essential for projects in varying climates.
• Screening and Field Use: Provides guidance for selecting the right test nozzle for either detailed specification testing (metal nozzle) or broader property screening and development (plastic nozzle).

Related Standards

For enhanced sealant testing and comprehensive assessment, ASTM C1183/C1183M-13(2018) references or relates to the following ASTM standards:

• ASTM C717 - Terminology relating to building seals and sealants, providing foundational definitions.
• ASTM D1475 - Test method for density of liquid coatings, inks, and related products, used for determining the specific gravity of the sealant.
• ASTM D2452 - Test method for extrudability of oil- and resin-base caulking compounds, an alternative for specific gravity determination.

Notably, there is no ISO equivalent to this test method at present. This standard aligns with international principles for standardization, supporting global trade and regulatory compliance for sealant manufacturers and construction professionals.

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
