Japanese Industrial Standards
One of the standards for Anti-Bacterial is the ISO 22196:2007, which is based on the Japanese Industrial Standards (JIS), code Z2801. This is one of the standards most often referred to in the industry with regards to tests on microbial activities (specifically bacteria) and in the JIS Z2801, two bacteria species are used as a standard, namely "E. Coli" and "Staphylococcus aureus". However, some companies may have the initiative to test more than just these two bacteria and may also replace "Staphylococcus aureus" with MRSA, the methicillin-resistant version of the same bacteria.
