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.
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.
Each guide includes material classifications, test methods, regional notes, and downloadable references where available.
Comprehensive guide to ASTM dimension stone specifications, test methods and manufactured stone veneer standards for North American projects.
Guide to CEN/EN natural stone product standards, test methods and CE marking requirements for projects across the European Union and EEA.
Cross-reference guide mapping ASTM dimension stone specifications and test methods to their European EN equivalents for global stone projects.
Use ASTM standards for US and Canadian projects. NBCC and CSA frequently reference ASTM C503, C568, C615, C616, C629, and related test methods.
Use EN standards for CE-marked products and ASTM ↔ EN mapping when translating specs across regions.
