Natural Stone Standards

ASTM · EN · Mapping

Authoritative reference for specifying, testing, and certifying natural stone — ASTM for USA & Canada, EN for European projects, and a cross-reference guide for global supply chains.

Why standards matter for stone projects

Every stone specification — from pool deck travertine to lobby granite — should reference the correct material standard and test methods. ASTM sets minimum performance thresholds for North American construction; EN standards govern CE-marked products in Europe. SmartStones publishes all three guides used by architects, fabricators, and importers daily.

Europe & export

Use EN standards for CE-marked products and ASTM ↔ EN mapping when translating specs across regions.
