ASTM D5665/D5665M-99a(2021)

Standard Specification for Thermoplastic Fabrics Used in Cold-Applied Roofing and Waterproofing

ABSTRACT
This specification covers thermoplastic fabrics such as polyester, polyester/polyamide bicomponent, or composites with fiberglass or polyester scrims that can be used during the construction of cold-applied roofing and waterproofing. The thermoplastic fabrics shall be classified as: Type I; Type II; Type III; Type IV; Type V; Type VI; and Type VII. Fabrics shall conform to the thickness, mass, and physical properties specified. Tests shall be performed to determine the properties of the material in accordance with the following test methods: unit mass; thickness; breaking load and elongation; trapezoid tearing strength; and puncture strength.
SCOPE
1.1 This specification covers thermoplastic fabrics such as polyester, polyester/polyamide bicomponent, or composites with fiberglass or polyester scrims that can be used during the construction of cold-applied roofing and waterproofing.  
1.2 This specification is intended as a material specification. Issues regarding the suitability of specific roof constructions or application techniques are beyond the scope of this specification.  
1.3 The specified tests and property values used to characterize the respective fabrics are intended to establish minimum properties. In-place system design criteria or performance attributes are factors beyond the scope of this material specification.  
1.4 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 nonconformance with the standard.  
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 D5665/D5665M-99a(2021) is a comprehensive standard issued by ASTM International that specifies requirements for thermoplastic fabrics used in cold-applied roofing and waterproofing systems. This specification covers various fabric types, including those made from polyester, polyester/polyamide bicomponent materials, and composites containing fiberglass or polyester scrims. The standard outlines essential material properties and test methods to ensure the quality, durability, and performance of these thermoplastic fabrics within construction projects, particularly where cold-applied systems are used for roofing or waterproofing.

Key Topics

• Material Types: The standard classifies thermoplastic fabrics into seven distinct types based on construction and composition, including spunbonded polyester, bicomponent polyester/polyamide, and composite fabrics with scrims and resins.
• Performance Requirements: Fabrics must meet specified minimum values for unit mass, thickness, breaking load, elongation, tearing strength, and puncture strength.
• Testing Procedures: Physical properties are measured according to referenced ASTM test methods, ensuring standardized evaluation of material performance.
• Workmanship and Appearance: The final fabric must be free of visible defects such as ragged edges, tears, wrinkles, or holes to guarantee reliability in application.
• Inspection and Rejection: Procedures for inspection, alternative inspection requirements, and criteria for rejection and resubmittal are detailed to maintain quality control.
• Packaging and Marking: Guidance is provided for securely packaging and clearly marking rolls, including requirements for identifying rolls with splices.

Applications

Thermoplastic fabrics specified under ASTM D5665/D5665M-99a(2021) are primarily used in:

• Cold-Applied Roofing Systems: Serving as a core reinforcement layer, these fabrics enhance membrane strength, durability, and resistance to weathering in cold-applied roofing applications.
• Waterproofing Membranes: Providing structural reinforcement within cold-applied waterproofing systems, the fabrics help prevent water ingress and improve the longevity of waterproof barriers in various construction settings.
• Commercial and Industrial Construction: Essential for projects requiring robust, reliable, and standardized waterproofing or roofing membranes that perform under various environmental conditions.
• Retrofit and Repair Applications: Used in restoration or overlay of existing roofing or waterproofing systems, offering additional reinforcement and improved performance characteristics.

Related Standards

ASTM D5665/D5665M-99a(2021) references several other important ASTM standards and resources, including:

• ASTM D123: Terminology Relating to Textiles
• ASTM D1079: Terminology Relating to Roofing and Waterproofing
• ASTM D1776/D1776M: Practice for Conditioning and Testing Textiles
• ASTM D1777: Test Method for Thickness of Textile Materials
