This is a disinfecting performance test method of wet wipers of the Japan Sanitation Materials Industrial Association. Use a wet wipe to wipe off the test carrier in which the bacterial solution is inoculated in a predetermined method to examine the number of raw bacteria on the test. The bacterial solution is added as a model dirt substance, and a beefbumbum albumin is added. ■ Examination method ① Preparation of samples (3 pieces each) Prepare as follows. ・ Test sample: sample (wet wipe) itself. It is also possible to make and use a liquid in which the liquid is impregnated in a cotton cloth. ・ Control sample: Cotton cloth (cotton 3-1, 15cm x 10cm) is impregnated into 1.5 times the amount of phosphoric acid vulnerable solution. ② Apply to the test carrier of testing solution Apply test fungus solution (usually a bouillon medium that is prepared in 1.0 to 5.0 × 10^9 cfu/ml in a cowbumbine albumin aqueous solution (model dirt)) is applied to the test car (stainless steel piece). ③ Wipe off test carriers using samples One sample is attached to a 150g weight, and the test car installed in the dedicated wiping device is in close contact with the test carrier, and the test carrier is 5 round trips at 120 times/minute intervals. ④ Measurement of raw bacteria The test carrier is identified and the number of bacteria is measured. ⑤ Evaluation Comparing the number of residual bacteria in the test carrier after wiping off the test samples and contrast samples, and calculating the disinfecting activity value. ■ Test bacterial species ・ STAPHYLOCCUSAUREUSNBRC12732 (Staphylococcus aureus) ・ ESCHERICHIACOLINBRC3972 (Escherichia coli) The nutritional conditions of test bacteria and bacterial solution may be changed from the rules for the test purposes. ■ The required amount of the sample ·size No particular limit ・ Number of sheets required More than 30 pieces including spare (in the case of the final product, unopened items are desirable.) ■ Information necessary for the test implementation It is smooth if you can get the following information when quoting. ・ Number of specimens ・ Requested products * 1 (except for Japanese reports) ・ Test bacterium species (if you want to do it with bacterial species different from the rules) ・ Wiping conditions * 2 (if there is a special request) * 1 If there is no particular request, only the Japanese sentence (test result of testing methods and test results tests, the number of raw bacteria after culture, disinfecting activity), no image). * 2 (Example: Number of wipes and speeds), we want to use multiple pieces, we want to use them except for the fixed number, we want to use it for testing for the test, and so on. deadline 3 weeks ~ ※Please contact us for more information. cost Please contact us.
