ASTM D3462/D3462M-23

Standard Specification for Asphalt Shingles Made from Glass Felt and Surfaced with Mineral Granules

ABSTRACT
This specification deals with the standards for asphalt roofing in shingle form, composed of glass felt or felts impregnated and coated on both sides with asphalt, and surface on the weather side with minerals. Physical requirements of the shingles such as behavior on melting, tear strength, wind resistance, fire resistance, softening point, and pliability shall be measured immediately after packaging or at a reasonable time. Physical and performance requirements after application and during in-service use are however beyond the scope of this specification.
SCOPE
1.1 This specification covers asphalt roofing in shingle form, composed of glass felt or felts impregnated and coated on both sides with asphalt, and surfaced on the weather side with mineral granules. This specification is designed for the evaluation of products as manufactured. The test methods, physical requirements, and minimum masses are to be measured immediately after packaging or at a reasonable time, as agreed upon between buyer and seller, after manufacture and before installation. Physical and performance requirements after application and during in-service use of the products described herein are beyond the scope of this material specification.  
1.2 Shingles meeting this specification are intended to be applied with a headlap of not less than 51 mm [2 in.].  
1.3 The shingles shall be supplied with a factory-applied self-sealing adhesive or be designed to be locked together during installation of the shingles.  
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 The following safety hazards caveat pertains only to the test method described in this specification: 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 D3462/D3462M-23 is a key international standard specifying the requirements for asphalt shingles made from glass felt and surfaced with mineral granules. Developed by ASTM International’s Committee D08 on Roofing and Waterproofing, this specification provides criteria for evaluating asphalt roofing shingles as manufactured-before installation and in-service use. The standard covers shingles composed of glass felt impregnated and coated with asphalt on both sides, finished on the weather-exposed side with mineral granules. ASTM D3462/D3462M-23 outlines detailed physical property requirements, test methods, and packaging specifications, ensuring the reliability and quality of asphalt shingles used in steep-slope roofing applications.

Key Topics

• Material Composition

  • Shingles consist of thin, porous glass felt reinforced as needed and fully coated with asphalt.
  • Finished with mineral granules on the weather-exposed side for durability and protection.
  • Reverse side treated with fine particulate material (e.g., sand, talc, mica) to prevent sticking during packaging.

• Physical Requirements

  • Performance criteria include behavior on heating, tear strength, wind resistance, fire resistance, softening point, and pliability.
  • Shingles must not stick together in the package and should be defect-free with uniform appearance.
  • Minimum mass and dimensional tolerances are strictly defined.

• Application Requirements

  • Intended installation with a minimum headlap of 51 mm (2 inches).
  • Shingles supplied with factory-applied self-sealing adhesive or designed to lock together during installation.
  • Dimensions, color, and style are to be agreed upon between buyer and seller.

• Testing and Sampling

  • Tests specified for evaluating the as-manufactured shingles include:
    • Fastener pull-through resistance
    • Tear strength
    • Wind resistance (Class A, per ASTM D3161/D3161M)
    • Fire resistance (Class A, per ASTM E108)
    • Pliability and asphalt softening point
    • Weight of displaced granules and mass composition

• Measurement Units

  • Standard permits use of either SI or inch-pound units, but they must not be combined in a single evaluation.

Applications

Asphalt shingles meeting ASTM D3462/D3462M-23 are widely used in:

• Residential and commercial steep-slope roofing: Ensures consistent performance and durability for single-family homes, multi-family buildings, and small commercial structures.
• New construction and re-roofing projects: Builders, roofing contractors, architects, and specifiers rely on this standard when selecting roofing materials for code compliance and warranty validation.
• Procurement and quality assurance: Manufacturers and purchasers use the defined criteria for product acceptance, ensuring delivery of roofing products that meet industry norms for wind and fire resistance, mass, flexibility, and appearance.

Following this ASTM specification in the selection and procurement process helps minimize installation issues, ensures roof longevity, and supports building code compliance.

4. Materials and Manufacture
4.1 The glass felt shall be a thin, porous sheet composed predominately of fine glass fibers uniformly deposited in a nonwoven
pattern. It is permitted to reinforce the glass felt with random or parallel-oriented glass yarns, or both, which are permitted to be
gathered or twisted, bonded or unbonded. The felt shall contain a substantially water-insoluble binding agent.
4.2 In the process of manufacture, one or more thicknesses of glass felt shall be impregnated with an asphaltic material. When
more than one thickness of felt is used, the mats shall be adhered to each other with a continuous layer of asphaltic material
between adjacent felts. The nature of the asphaltic material and the thickness of the adhering layers shall ensure a firm bond
between adjacent glass felts. The single felt or laminated felts shall then be coated on both sides with a hot asphaltic coating.
4.3 The asphaltic material used to impregnate, laminate, and coat the glass felt, in any or all of these functions, is permitted to
be compounded with a mineral stabilizer. Glass fibers are permitted to be compounded with the asphalt in addition to, or instead
of, the mineral stabilizer.
4.4 All surfaces to be exposed to the weather, when the product is properly installed, shall be surfaced with mineral granules
embedded in the asphalt coating.
4.5 The reverse side shall be covered with a suitable material such as pulverized sand, talc, or mica to prevent the shingles from
sticking together in the package.
4.6 The shingles shall have a factory-applied adhesive that will seal the shingles together after application when activated by heat
and sunlight or be designed to be locked together during installation of the shingles.
5. Physical Requirements
5.1 Shingles shall not stick together in the package so as to cause damage upon being unpacked at ambient temperatures.
5.2 The shingles shall conform to the requirements prescribed in Table 1.
5.3 Fire Test Classification—Shingles shall pass all of the Class A fire exposure test requirements of Test Method E108.
5.4 Wind Resistance, Shingles shall pass the wind resistance test requirements of Test Method D3161/D3161M.
6. Dimensions, Masses, and Permissible Variations
6.1 The form and size of the shingles shall be as agreed upon by the purchaser and seller.
