ASTM D6223/D6223M-21

Standard Specification for Atactic Polypropylene (APP) Modified Bituminous Sheet Materials Using a Combination of Polyester and Glass Fiber Reinforcements

ABSTRACT
This specification covers Grades G (granule surfaced) and S (smooth surfaced) prefabricated bituminous sheet materials reinforced with a combination of polyester fabric and glass fiber, and modified with atactic polypropylene (APP), intended for use in the fabrication of multiple ply roofing and waterproofing membranes. This specification is intended as a material specification only, and does not address issues regarding the suitability of specific roof constructions or application techniques. The specified tests and property limits used to characterize the sheet materials covered by this specification are intended to establish minimum properties. Also, in-place roof system design criteria such as fire resistance, field strength, impact/puncture resistance, material compatibility, uplift resistance, the need for field applied coatings, and others are factors beyond the scope of this material specification. The physical properties for which sheet materials shall be tested on and consequently conform to are peak load before and after heat conditioning, elongation at peak load, tear strength, low temperature flexibility, dimensional stability, compound stability, granule embedment, water absorption, moisture content, and low temperature unrolling.
SCOPE
1.1 This specification covers prefabricated modified bituminous sheet materials reinforced with a combination of polyester fabric and glass fiber, with or without granules, that use atactic polypropylene (APP) as the primary modifier and are intended for use in the fabrication of multiple ply roofing and waterproofing membranes.  
1.2 This specification is intended as a material specification only. 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 limits used to characterize the sheet materials covered by this specification are intended to establish minimum properties. In-place roof system design criteria such as fire resistance, field strength, impact/puncture resistance, material compatibility, uplift resistance, the need for field applied coatings, and others, 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 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.  
1.6 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 D6223/D6223M-21 is the internationally recognized standard specification for Atactic Polypropylene (APP) Modified Bituminous Sheet Materials using a combination of polyester and glass fiber reinforcements. Developed by ASTM International, this standard establishes the minimum material requirements for prefabricated APP-modified bituminous sheets used in multiple ply roofing and waterproofing membrane systems. It applies to two main surfacing types: granule-surfaced (Grade G) and smooth-surfaced (Grade S) materials. This specification helps ensure consistent quality, performance, and durability of roofing and waterproofing products that incorporate both polyester and glass fiber reinforcements with APP modification.

Key Topics

• Material Composition: The standard covers bituminous sheet materials that are reinforced with both polyester fabric and glass fiber, modified with atactic polypropylene (APP) for enhanced resistance and flexibility.
• Surfacing Grades:
  • Grade G (Granule-surfaced): Sheets surfaced with mineral granules for added weather resistance.
  • Grade S (Smooth-surfaced): Sheets with a plain finish, suitable for a variety of roofing and waterproofing applications.
• Physical Property Requirements: The standard specifies minimum requirements for:
  • Peak load (before and after heat conditioning)
  • Elongation at peak load
  • Tear strength
  • Low temperature flexibility
  • Dimensional and compound stability
  • Granule embedment (for Grade G)
  • Water absorption and moisture content
  • Low temperature unrolling performance
• Dimensions and Tolerances: Includes specifications for sheet thickness, mass, roll width, area, and selvage dimensions, ensuring uniformity and compatibility with application needs.
• Manufacturing Quality: Mandates standards for coating, finish, and appearance, requiring products to be free from defects such as holes, cracks, wrinkles, or improperly coated reinforcement.
• Sampling and Testing: References ASTM-based test methods for sampling and evaluating physical properties, such as ASTM D5147/D5147M and D5636/D5636M.

Applications

Bituminous sheet materials specified in ASTM D6223/D6223M-21 are principally used to fabricate multi-ply roofing membranes and waterproofing systems. Key areas of use include:

• Commercial and Industrial Roofs: Multi-layer membrane systems relying on both polyester and glass fiber APP-modified sheets for superior durability, weather resistance, and flexibility.
• Waterproofing Membranes: Applications beneath terraces, green roofs, and parking decks where water tightness and resistance to thermal cycling are critical.
• Restoration and Retrofit Projects: Enhancing older roofing assemblies with modern, APP-modified sheets that meet current standards for performance.
• High-performance Building Envelopes: Providing consistent quality for complex or demanding building designs, where reliable waterproofing and sustained physical performance are essential.

Related Standards

Several other ASTM standards interact with or reference ASTM D6223/D6223M-21 in the context of bituminous sheeting materials, roofing, and waterproofing. Relevant standards include:

• ASTM D1079: Terminology Relating to Roofing and Waterproofing - Standardizes industry terms used within this specification.
• ASTM D5147/D5147M: Test Methods for Sampling and Testing Modified Bituminous Sheet Material - Specifies testing protocols referenced for verifying physical properties.
• ASTM D5636/D5636M: Test Method for Low Temperature Unrolling of Felt or Sheet Roofing and Waterproofing Materials - Details procedures to evaluate performance in low temperature conditions.

By following ASTM D6223/D6223M-21, manufacturers, contractors, and designers can assure end-users of product quality and suitability while supporting robust, durable waterproofing and roofing solutions for a wide range of building applications.
