EN 12004 – European Standard
EN 12004 is a widely used European Standard. It outlines requirements for health, safety, and environmental protection in accordance with European Union laws and regulations. Its objective is to facilitatecommerce and create a unified standard across European countries.
The European standard for cementitious adhesives is EN 12004. This standard specifies detailed test methods and performance requirements for cementitious adhesives, which are categorized as Cementitious (C), Dispersion (D), and Reaction resin (R). The standard divides products into two performance levels: Standard (C1) and High Performance (C2). The details
for each test category are as follows:
| Number /Letter | Meaning |
| C | Cementitious (Cement-based adhesive) |
| 1, 2 | Standard and high-performance properties, respectively |
| T | Thixotropic (Non-sag on vertical surfaces) |
| E | Extended open time (Longer working time than normal) |
| S1 / S2 | High flexibility |
Many Sika products meet the EN 12004 European Standard. This is a crucial criterion for projects requiring tile adhesives for their performance, adhesion, non-sag properties, and ease of use.
