Mould and bacteria resistance
Ecophon products have been tested to ensure they do not serve as a natural breeding medium for mould and bacteria.
By keeping the environment of the ceiling clean, and having a controlled climate below the critical humidity and temperature level, the risk for these micro-organisms is reduced considerably. Tests have been performed on Ecophon tiles according to ISO 846:2019methods A (fungal growth) C (bacteria) and/or ASTM D3273-16 (fungal growth):
ISO 846, Method A
- Paecilomyces variotii
- Penicillium funiculosum
- Aspergillus niger
- Gliocladium virens
- Chaetomium globosum
ISO 846, Method C
- Pseudomonas aeruginosa
ASTM D3273-16
- Aureobasidium pullulans
- Aspergillus niger
- Penicillium citrinum
The ISO 846 standard classifies materials from Class 0 (no growth of microorganisms) to Class 5 (heavy growth of microorganisms). Ecophon products that have been tested according to ISO 846:1997 have reached Class 0 or Class 1.
The ASTM D3273-16 standard evaluate the fungal growth according to a scale from 0 to 10, where rating 0 is 91-100% invasion of fungus and rating 10 has no growth of fungus.
Always refer to a product’s technical datasheet to ensure its compatibility with specific mould and bacteria resistance requirements.
