ASTM C1737-23 PDF

Overview

ASTM C1737-23: Standard Guide for Evaluating Temperature Effects to Aerosol Foam Sealant During and After Dispensing provides a laboratory-based approach to assess how temperature impacts the dispensing and quality of aerosol foam sealants, specifically focusing on single-component polyurethane and latex foam types. Developed by ASTM International, this guide is a recognized reference for benchmarking foam sealant performance when subjected to various product and ambient temperatures. Foam sealants are primarily used as air barriers to control air movement in and out of building enclosures, contributing to improved energy efficiency and building performance.

Key Topics

• Temperature Effects: The standard highlights the general effects of both product and ambient air temperatures on the dispensing characteristics and final quality of aerosol foam sealants.

• Foam Sealant Types: Applies to polyurethane and latex aerosol foam sealants, both commonly used in construction for their air-sealing capabilities.

• Test Procedures: Provides guidance on laboratory test procedures, including preparation, conditioning, and evaluation at specified temperature ranges.

• Performance Characteristics: Focuses on evaluating:

  • Flow rate during dispensing
  • Tack-free time (time until surface is no longer sticky)
  • Friability (tendency to crumble under light pressure)
  • Skin and cell appearance of the cured foam

• Data Reporting: Outlines essential data to be recorded, such as product details, testing temperatures, dispensing direction, and qualitative rankings on foam appearance and structure.

• Safety and Suitability: Emphasizes the need for users to follow safety practices and determine the suitability of the product for each specific application.

Applications

• Building Enclosure Air Sealing: The primary application of this guide is assessing aerosol foam sealants used to reduce air infiltration and exfiltration in walls, roofs, and other parts of building envelopes.
• Product Benchmarking: Manufacturers and evaluators can benchmark product performance against internal and industry standards under controlled temperature conditions.
• Quality Control: Construction professionals, quality managers, and product developers use the guide for product comparison, ensuring foam sealants reliably perform across different temperature scenarios.
• Specification Compliance: Helps building specifiers, architects, and contractors to select suitable foam sealant products by referencing tested performance under temperature variations.
