JIS Z 2801 Test for Antimicrobial Activity of Plastics

The JIS Z 2801 method tests the ability of plastics and other antimicrobial surfaces to inhibit the growth of microorganisms or kill them. The procedure is very sensitive to antimicrobial activity. It involves inoculating the antimicrobial surface with a moderate, standardized microbial population, then covering it with a plastic film to prevent evaporation over the course of the contact time, which is usually 24 hours. After the contact time, percent reductions are calculated.

The JIS Z 2801 procedure has been adopted as an International Organization for Standardization (ISO) procedure, ISO 22196.


Summary of the JIS Z 2801 Test


Strengths of the JIS Z 2801 Test


Weaknesses of the JIS Z 2801 Test


Though the JIS Z 2801 test is somewhat "best-case," it is an excellent way to quantify the antimicrobial activity level of an antimicrobial surface, especially one that is hydrophobic. Among the various tests for antimicrobial activity of surfaces, this has emerged as one of the industry standards.
