The Facts on Stone: ASTM Standards

When selecting a product, nothing is more important than access to evidence-based data. The American Society for Testing and Materials (ASTM) provides consumers with accurate knowledge of various products to enable them to make the best purchasing decisions. Natural stone and engineered quartz are among the products routinely tested. ASTM testing data is critical when choosing the proper stone for your project. Marble is a classic choice, but is not suitable for all projects due to its proclivity to staining.

Engineered quartz is almost impermeable to staining, but is less heat resistant than certain types of granite. Every stone has its pros and cons, and adequate research will enable you to choose the best product. See our charts below for more information on engineered quartz and natural stone testing results:
