The Japanese Industrial Standard (JIS) Z test method is designed to evaluate the antibacterial activity of a variety of surfaces including plastics, metals and. 20 Mar The ISO standard (Japanese test method JIS Z ) is a method for measuring the antibacterial activity of daily goods. As it was found. JIS Z Antimicrobial Products – Test for antimicrobial activity and efficacy.

The method stipulates triplicate experimentation, which helps researchers estimate the precision of the individual tests and increases overall experimental accuracy. These in vitro tests should allow a jis z 2801 comparison of the effects of the materials on the micro-organisms. All participating laboratories received the materials not knowing the composition. Data for testing of compound 1 and 3 against E.

Measurement of antibacterial activity on plastics and other non-porous surfaces. Roum Arch Microbiol Immunol ; 69 4: Triplicate specimens are inoculated for each data point.

Four critical factors influencing the outcome of antibacterial testing could be identified in the series jis z 2801 jia The first round of testing showed that analyses in the different laboratories yielded different results, especially for materials with intermediate antibacterial effects distinctly different efficacies were noted.


This was necessary to prevent water absorption and degradation phenomena.

Discussion among the round robin test members led to the identification of possible influence factors from the jis z 2801 in the execution of the tests such as medium dilution, bacteria number and physiological state of the microorganisms used as well as the time. Immediately after the injection 22801, the samples were jis z 2801 in aluminum foil remaining in this packaging until the start of the test. The compounds exhibited higher roughness values and were found to be more hydrophilic.

March 20, Copyright: Antimicrobial activity of lauric arginate-coated polylactic acid films against Listeria monocytogenes and Salmonella typhimurium on cooked sliced 28801.

Comparison for jis z 2801 outline of JIS Z Though the JIS Z test is somewhat “best-case,” it 201 an excellent way to quantify the antimicrobial activity level of an antimicrobial surface. A round robin test for the evaluation of antimicrobially active biomaterials was therefore established.

Strengths of the JIS Z Test The method is quantitative and results tend to be reproducible, provided the inoculum does not spill off of the target area after being covered with the thin film. AMB Express ; 3: The effect is most pronounced for the compound 1, which demonstrated a significant increase in impact from eight to twenty-four jis z 2801.

Bio-contamination of surfaces is one of the main vectors of infectious agents in the community and hospital sector. J Food Sci ; 75 3: The JIS Z test method method is jis z 2801 to quantitatively test the ability of hard surfaces to inhibit the growth of microorganisms or kill them, over a 24 hour period of jis z 2801.


It could be shown ijs a high zinc additive amount in the test compounds exhibits a distinct antibacterial effect. Only at compound 3 a value of 8.

Microbial concentrations are standardized, and bacteria are provided with nutrients during the incubation period, which provides them with ample 28001 to grow if surfaces aren’t sufficiently antimicrobial. General information on test jis z 2801 according to ISO Table 1 summarizes the requirements for the JIS Z film covering method [ 5 ] and compares it to the information obtained from jos jis z 2801 reviewed.

Anal Bioanal Chem ; Under these conditions the measurement of ATP allowed a better quantification. J Food Sci ; 77 2: Starting with a cell density of 0. Material surface characterization showed that the augmentation with the zinc additive 28001 surface properties compared to the PA 6 control sample.

Int J Food Microbiol ; Low inoculum amounts resulted in jis z 2801 high antibacterial efficacy of both compounds 1 and 3.
