Why Choose Artificial Stone for Global Projects?
Artificial stone can support demanding global projects, but safety claims need measurable evidence. ASTM is not one single approval; it is a family of technical methods. The correct method depends on use, exposure, and design. Countertops, façades, floors, and wet areas require different evaluations. A responsible supplier should provide current laboratory reports, sample identification, test conditions, and production-batch details.
Evidence matters.
EN 14617 is especially relevant to agglomerated stone products. Its test methods examine properties such as water absorption, flexural strength, abrasion resistance, and resistance to temperature changes. These results help specifiers judge cracking, staining, and surface wear in real installations.
A polished slab may look flawless under showroom lighting. Site conditions are less forgiving. Poor support, incorrect joints, or sudden temperature changes can still cause failure.
ISO 22196 evaluates antibacterial activity on treated, non-porous surfaces under controlled laboratory conditions. It does not prove that a room remains hygienic after installation. Cleaning routines, damaged finishes, moisture, and user behavior still influence performance.
ASTM and EN results should also be read with installation guidance and local project requirements. I have found that reports sometimes appear impressive but omit sample age or preparation details. That gap deserves questions.
No standard replaces careful inspection, competent cutting, edge sealing, and documented quality control. Safety is a process, not a logo.
