Proven by independent JIS Z 2801 testing
On the brass holder, bacteria fall to nearly zero within 24 hours
In JIS Z 2801 antibacterial testing by an independent institution, it recorded an antibacterial activity value of R=4.5 against Staphylococcus aureus and R=6.3 against E. coli.
Both far exceed the threshold for “antibacterial effect” (R≥2.0), and after 24 hours, bacteria had decreased to undetectable levels.
In testing under the same conditions, bacteria multiplied on an untreated plastic piece (control), while on the surface of the brass magnet holder they fell to nearly zero.
Testing laboratory: Hygiene Microbiology Research Center (Japan) / Test No. 2026D-BT-04067 / Control: untreated polypropylene resin sample. Values measured after 24 hours of incubation.
