Overview
ISO 19947:2026 – Engineered stone - Vocabulary is an international standard developed by ISO that establishes clear, standardized terminology for the engineered stone industry. This standard covers terms and definitions relevant to the production, processing, and application of engineered stone materials, such as those used for countertops, vanities, floor and wall coverings, and related accessories. The vocabulary included in ISO 19947:2026 provides a common language that supports consistency and clarity across manufacturing, fabrication, installation, and specification processes worldwide.
Key Topics
ISO 19947:2026 includes terminology addressing:
- Engineered Stone Products: Definitions and classifications for various engineered stone items-including slabs, tiles, panels, cut-to-size products, rough slabs, and more.
- Raw Materials: Clear distinctions for sourced raw materials, including indigenous raw materials, post-consumer and pre-consumer materials, reclaimed waste, and recycled content.
- Aggregates and Fillers: Terms covering different types of aggregates (e.g., carbonate rock, silicate rock, quartz, granite) and fillers used in engineered stone.
- Binders and Additives: Definitions for materials such as cement, various resin types (terephthalic, unsaturated polyester, thermosetting), and common additives (adhesion promoters, pigments, accelerators).
- Process Operations: Terminology for the various stages of engineered stone production-including mixing, moulding, calibration, curing (cold and hot), hydration, distribution, and surface finishing.
The document also clarifies familiar industry terms such as artificial marble, manufactured stone, and quartz surfacing, ensuring that all stakeholders use a consistent vocabulary.
Applications
Adopting ISO 19947:2026 in practice delivers valuable benefits to professionals at every stage of the engineered stone life cycle:
- Manufacturers: Use the standardized terms for product descriptions, quality control documentation, and communication with suppliers and clients.
- Architects and Designers: Specify engineeered stone materials confidently, knowing terminology aligns with international best practices.
- Installers and Fabricators: Reference standardized process operations and product classes to reduce miscommunication during project planning and execution.
- Material Suppliers: Ensure raw materials and additives are described accurately to meet compliance requirements.
- Quality Auditors and Certification Bodies: Employ a uniform vocabulary for audits, certifications, and compliance verification across global projects.
By creating a shared understanding, ISO 19947:2026 supports improved project outcomes, simplified procurement processes, and enhanced international trade in engineered stone products.
