ASTM D3018/D3018M-22 PDF

Overview

The ASTM D3018/D3018M-22: Standard Specification for Class A Asphalt Shingles Surfaced with Mineral Granules establishes requirements for asphalt roofing shingles designed for optimal performance and safety. This specification covers both self-sealing (Type I) and non-self-sealing (Type II) asphalt shingles that are surfaced with mineral granules and meet the highest Class A fire resistance standards. The shingles addressed in ASTM D3018/D3018M-22 use organic felt or glass mat bases, are saturated with asphalt, and have a weather side completely covered in mineral granules to enhance durability and weather resistance.

Key Topics

• Product Types: The standard specifies two types of asphalt shingles:
  • Type I: Self-sealing shingles with a factory-applied adhesive for additional weather resistance.
  • Type II: Non-self-sealing shingles, suitable for applications where self-sealing properties are not required.
• Material Composition:
  • Shingles must utilize organic felt or glass mat, saturated or impregnated with hot asphaltic material.
  • The weather-exposed surface must be evenly coated and embedded with mineral granules for added protection.
  • The reverse side is treated to prevent sticking in packaging.
• Performance Requirements:
  • Compliance with Class A fire test (ASTM E108), behavior on heating, and wind resistance (ASTM D3161/D3161M).
  • Physical criteria for loss on heating, uniform finish, permissible dimensional variations, and defect-free appearance.
• Packaging & Identification:
  • Shingles must be packed and marked to ensure safe transport and easy product identification, including information on fire and wind classification.
  • Application instructions must accompany each package.

Applications

ASTM D3018/D3018M-22 is widely referenced in both residential and commercial construction projects where high-performance, durable, and fire-resistant roofing is critical. Typical applications include:

• Roofing for homes, apartment buildings, and commercial structures requiring Class A fire ratings.
• Sites exposed to high winds or extreme weather, utilizing self-sealing Type I shingles for improved wind uplift resistance.
• Projects prioritized for longevity and aesthetics, given the uniform mineral granule surface which enhances both durability and curb appeal.

Compliance with this standard helps architects, builders, and roofing contractors ensure that installed shingles meet stringent fire, wind, and durability criteria, thereby reducing risks for property owners and supporting code compliance.

Related Standards

To fully meet industry and project requirements, ASTM D3018/D3018M-22 references and often works in conjunction with several other ASTM roofing standards, including:

• ASTM D228/D228M: Test Methods for Sampling, Testing, and Analysis of Asphalt Roll Roofing, Cap Sheets, and Shingles Used in Roofing and Waterproofing.
• ASTM D1079: Terminology Relating to Roofing and Waterproofing, providing standard definitions for industry terms.
• ASTM D3161/D3161M: Test Method for Wind Resistance of Steep Slope Roofing Products (Fan-Induced Method).
• ASTM E108: Test Methods for Fire Tests of Roof Coverings, specifying Class A fire exposure test procedures.

By adhering to these interconnected standards, stakeholders in roofing and construction ensure products and processes are safe, reliable, and consistent with international guidelines.
