Resistance against mould, wood decaying fungi, bacteria and algae In many cases it is important that materials and products can resist attack from microorganisms of different kinds to function as intended.
There are always existing microbes in the environment where the material/product, newly produced or after natural aging, will be used. It can be materials like plastics, rubber, wood, composites, ceramics, paints and varnishes and products like cables, equipment for the air flight industry and different kinds of textiles.
There are a number of standard methods for testing microbial resistance, each intended for a certain purpose or a specific type of material/product to be tested. Many of these tests can be performed at SPs Biolab.
Microorganism - Examples of standards that we use
- Mould - ISO 846, MIL-STD-810F, RTCA/DO-160D, IEC 600-68-2-10, BS 1982-3, ASTM 5590
- Bacteria- ISO 846
- Microorganisms in soil - ISO 846, EN 12225, ISO 11721
- Algae - ASTM D5589
- Wood-decaying fungi - EN 113, EN 839, AWPA E10
Reduction of microorganisms in liquids and air
In environments where airborne and / or fluid living microorganisms can grow, often requires methods to reduce the number of live microorganisms. SP Biolab performs tests in which the bacteria-reducing effect of methods can be evaluated.
