Regulation
Mandatory provisions where the building, use and work fall within their legal scope.

What is mandatory, and what describes technical performance.
CalcuCeram identifies the type, territory and scope of each source. A product standard does not design the project, and professional good practice is not presented as law.
Five levels that must not be confused
Technical standard
A consensus document for products, design or execution whose effect depends on the project context.
Manufacturer
Performance, preparation, declared field of use and limits of the actual product or system.
Good practice
Reasoned professional criteria used to reduce risk without inventing a universal obligation.
Common practice
A widespread method that may be useful, insufficient or unsuitable for a particular project.

Products and placing on the market
- Regulation (EU) 2024/3110: the construction products framework and its applicable timetable.
- EN 12004-1: requirements, assessment, classification and marking of tile adhesives.
- Scope: declared performance does not validate the substrate, environment or complete installation system.

Main Spanish framework and references
- CTE: the regulatory framework within the scope of each Basic Document and the work concerned.
- UNE 138002:2023: general rules for bonded ceramic tiling.
- UNE-EN 12004-1:2017: adhesive classification; UNE recorded it as current at the documented review date.
- UNE-EN 13888-1:2024: classification and marking of grouting materials.

Main French installation and product references
- NF DTU 52.2, June 2022: standard clauses for bonded installation within its field of application.
- NF EN 12004-1, April 2017: the current French adoption for tile-adhesive classification.
- System-specific documents: product data sheet, QB certification, Avis Technique, DTA, ATEx or e-Cahier where required.
- Scope: substrate, room, water exposure and the complete system still require project-specific checks.
Applied in CalcuCeram
Calculation remains separate from technical validation.
The plan changes the geometry; substrate, joints and installation requirements still need validation.
Basin and edge quantities do not validate structure, waterproofing or suitability for immersion.
EN 12004-1 classification is read together with eight technical criteria and the territorial system documents.
