4 Evaluation of antibacterial properties

This standard specifies the test method according to the total anti-bacterial rate (R total) have been evaluated.

Antibacterial rate >=90%, has an antibacterial effect;

Antibacterial rate >=99%, with strong antibacterial effect.

Note. At the same time indicate the photocatalytic antibacterial contribution (R light) at 365nm light source on the report.
