This European Standard specifies requirements for flat modular tiles of natural stone which are made for internal (including enclosed public transport premises) and/or external uses as floorings, stairs and wall and ceiling finishes. This European Standard does not cover mineral aggregates and artificial agglomerated stone material and does not cover installation.

Natursteinprodukte - Fliesen - Anforderungen

Diese Europäische Norm legt Anforderungen an ebene Fliesen aus Naturstein fest, die als Belag für Fußböden und Treppenstufen sowie als Decken- und Wandbekleidung im Innenbereich (einschließlich innenliegende Einrichtungen des öffentlichen Verkehrs) und/oder Außenbereich eingesetzt werden. Nicht erfasst werden in dieser Europäischen Norm mineralische Gesteinskörnungen und künstlich hergestelltes Gesteinsmaterial sowie die Verlegung.

Produits en pierre naturelle - Plaquettes modulaires - Exigences

La présente Norme européenne définit les exigences relatives aux plaquettes modulaires planes en pierre naturelle destinées aux usages intérieurs (y compris les lieux de transports publics fermés) et/ou extérieurs comme finitions de revêtements de sols, d’escaliers, de murs et de plafonds. La présente Norme européenne ne couvre pas les agrégats minéraux ni les matériaux rocheux agglomérés artificiellement, et ne concerne pas la mise en oeuvre.

Proizvodi iz naravnega kamna - Ploščice - Zahteve

Ta dokument določa zahteve za ploščate ploščice iz naravnega kamna, ki se uporabljajo za tlake, stopnice ter navpične in stropne obloge. Standard ne zajema mineralnih agregatov in materiala iz umetnega aglomeriranega kamna ter ne obravnava polaganja.

Overview

EN 12057:2015 - Natural stone products - Modular tiles - Requirements is a CEN (European) standard that specifies requirements for flat natural stone modular tiles intended for internal and/or external use as floorings, stairs and wall/ceiling finishes. It applies to tiles with a nominal thickness ≤ 12 mm and covers product characteristics, testing, sampling and factory production control. The standard does not cover mineral aggregates, artificial agglomerated stone, or installation.

Key Topics

• Geometrical characteristics and tolerances
  • Defines dimensions, flatness and squareness tolerances (e.g., calibrated vs non‑calibrated tiles; thickness tolerances such as ±1.5 mm non‑calibrated, ±0.5 mm calibrated).
• Surface finish
  • Requirements for uniform finishes extending to tile edges; allowance for stone‑specific patching/fillers where applicable.
• Physical and mechanical properties
  • Includes flexural strength, bond (adhesion) strength, water absorption (atmospheric and by capillarity), apparent density, open porosity and durability indicators.
• Performance characteristics
  • Reaction to fire, thermal shock resistance, resistance to thermal and moisture cycles, slip and skid resistance, tactile indicators, direct airborne sound insulation, thermal conductivity, and release of dangerous substances.
• Testing and sampling
  • References specific natural stone test standards (e.g., EN 1925, EN 1936, EN 12372, EN 13755, EN 14066) and sets rules for sampling including sampling at point of delivery.
• Assessment & certification
  • Introduces Assessment and Verification of Constancy of Performance (AVCP), factory production control (FPC) requirements and documentation (type testing, test reports).
• Regulatory support
  • Annex ZA maps the standard to the EU Construction Products Regulation (CPR) requirements, DoP examples and CE marking guidance.

Applications

• Product specification and quality control for manufacturers and stone processors producing modular tiles.
• Technical performance criteria for architects, specifiers and consultants when selecting natural stone for floors, stairs and wall finishes.
• Basis for testing laboratories and conformity assessment bodies performing product tests and issuing reports.
• Compliance support for construction product compliance officers, importers and distributors preparing Declarations of Performance (DoP) and CE marking.

Who Uses This Standard

• Natural stone tile manufacturers and exporters
• Architectural and engineering firms specifying finishes
• Testing & certification laboratories
• Construction product compliance teams and regulators
• Procurement teams validating supplier performance
