ETA 24/0895: European Technical Assessment for Terasun TSM Fiber Cement Board
What ETA 24/0895 means for Terasun TSM fiber cement board: scope, declared performances, validity, and how to use it in building specifications across Europe.
ETA 24/0895: European Technical Assessment for Fiber Cement Board
What is a European Technical Assessment (ETA)?
A European Technical Assessment (ETA) is a formal technical document issued under the Construction Products Regulation (EU) No 305/2011 (CPR). It enables manufacturers to CE-mark construction products that are not fully covered by a harmonised European standard.
For Terasun TSM fiber cement board, ETA 24/0895 was issued following assessment of the product's performance characteristics relevant to its intended uses: facade systems, wet rooms, and fire-rated wall assemblies.
Scope of ETA 24/0895
ETA 24/0895 covers Terasun TSM fiber cement board — an inorganic building board manufactured from Portland cement, inorganic fillers, and reinforcing fibres (no asbestos). The assessment covers the following intended uses:
- Ventilated facade systems — as a facade board in drained and ventilated cladding systems
- Wet rooms and bathrooms — as a tile backing board and sheathing in areas of high moisture exposure
- Fire-rated wall assemblies — as part of tested wall systems achieving E 120 / EI 90 / EW 120
Declared Performance Characteristics
The ETA confirms the following declared performance values for Terasun TSM 12 mm board:
| Characteristic | Performance | Test Standard |
|---|---|---|
| Moisture classification | Category A | EN 12467 |
| Reaction to fire | A1 | EN 13501-1 |
| Fire resistance (wall assembly) | E 120 / EI 90 / EW 120 | EN 13501-2 |
| Weight | 9.96 kg/m² | Declared |
| Format | 1,220 × 2,440 mm | Declared |
| Available thicknesses | 6, 8, 10, 12, 15, 18 mm | Declared |
*Note: Fire classification E120/EI90/EW120 applies to the specific tested wall assembly using 12 mm boards, not to the board alone. See fire test report FIRES-CR-284-25-AUPE for system details.*
CE Marking Reference
The CE marking for Terasun TSM board issued under ETA 24/0895 is:
CE 1023-CPR-1565 P
- Declaration of Performance (DoP): TRS-20250610F
- Environmental Product Declaration (EPD): EPD-IES-0018268 (ISO 14025)
- Fire test report: FIRES-CR-284-25-AUPE
Why ETA Matters for Specifiers
Legal compliance under CPR: The Construction Products Regulation requires CE marking for construction products covered by a harmonised standard or ETA. Products without CE marking cannot be legally placed on the EU/EEA market for regulated uses.
Building permit documentation: Many EU member state building authorities require ETA documentation as part of building permit applications, especially for products used in facades or fire-rated constructions.
Structural engineers and fire engineers: The ETA provides the declared performance values that structural and fire engineers need when designing systems using Terasun TSM board.
Insurance and warranty: Most European building insurers and warranty providers require products to carry CE marking and have ETA or harmonised standard compliance documentation.
