ASTM D3462 / D3462M

What does the test involve?

Covers asphalt shingles of glass felt impregnated and coated on both sides with asphalt and surfaced weather-side with mineral granules. Shingles meeting the specification are intended to be applied with a headlap of not less than 2 in (51 mm), and are supplied with a factory-applied self-sealing adhesive or designed to interlock.

Common misconceptions

• Compliance with D3462 is a floor, not a mark of quality. Nearly every shingle sold in the US meets it.
• Performance after the shingle is installed and in service is explicitly outside the scope of this specification. It describes the product as manufactured.
• The most recent edition we have located is D3462/D3462M-23. We have read the public abstract, not the full paywalled standard, so we do not publish its numeric physical requirements.
