EN 12440: A necessary review of the denomination criteria standard to elevate EU natural stone in a digital and sustainable market

ABSTRACT: The European standard EN 12440, which regulates the denomination of natural stones, is a vital strategic asset for the industry's competitiveness. However, its effectiveness has long been compromised by ambiguous criteria and a slow revision process. As the new Construction Products Regulation (CPR) and the introduction of Digital Product Passports (DPPs) make traceability and transparency mandatory, the shortcomings of the standard have become a critical liability. This paper presents a detailed analysis of EN 12440's deficiencies and, drawing on the work of a multidisciplinary technical group, outlines concrete proposals for its modernisation. The aim is to transform the standard into a robust and dynamic tool, enabling the natural stone sector to meet future regulatory, digital, and sustainability requirements.
