This is the test standard of AATCC (US textile science and technology and dyeing technology association). We quantitatively examine the effects of bacteria in antibacterial fiber products. Please contact us for other standards of AATCC (TM147, etc.). ■ Examination method ① Preparation of test spore solution 0.05%polysolbate 80 Aquarium is prepared using a triple -sower yabuyon or neutrient medium diluted by an aqueous solution. It is also possible to change this nutritional conditions for the test purpose. ② Preparation of sample Cut the sample (an antibacterial processing test piece or a non -processed test piece) into a circular with a diameter of 4.8 ± 0.1 cm or a square of 3.8 ± 0.1 cm on a side to 1.0 ± 0.1 g in total. * The number of examinations is not specified in the test document, but we will prepare three points to be stacked to 1.0 ± 0.1 g per sample, and perform the test at the same time. If you have any requests for repeated exams, please let us know. ③ Inoculation and culture of test spore fluids A test solution of 1.0 ± 0.1 ml of 1.0 ± 0.1 ml of the sample is vaccinated, put in a sterilized sealed container, and then cultured at 37 ± 2 ° C for 24 hours. ④ Inoculation and culture of testing solution Immediately after vaccination and 24 hours after the culture, the sample is washed out with 100 ml of SCDLP liquid medium, and the 10 -fold diluted series of the solution is prepared with purified water. After inoculation into a normal agar medium (n = 2), then culture at 37 ± 2 ° C for 24 to 48 hours to count the colony. ⑤ Evaluation Calculate the perCentration (R) based on the provisions. ■ Test bacterial species ・ STAPHYLOCCUSAUREUS (Staphylococcus aureus) NBRC13276 ・ KlebsieLLAPNEUMONIAE (pneumonia bacilli) NBRC13277 * For the test purposes, the bacterial species can be changed from the specification. ■ The required amount of the sample Minimum required amount: Antibacterial processing test pieces and non -processed test pieces 12.0g or more (6.0g per bacterium or more) * If possible, we would appreciate it if you could provide more than 1.5 to 2 times the required number, including the spare. ■ Information necessary for the test implementation It is smooth if you can get the following information when quoting. ・ Number of specimens ・ Presentation of specimens corresponding to non -processed test pieces ・ Requested effects * (except for the Japanese Report) ・ Test bacterium species (if you want to do it with bacterial species different from the rules) ・ How to make a test piece (when you want to test using a test piece processed with liquid or wet wipe) * If there is no particular request, only the Japanese sentence (test method and test result (determination result of the testing conditions, the number of raw bacteria, the number of percentration), no images) will be. ■ Delivery date 3 weeks ~ ※Please contact us for more information. ■ Expenses Please contact us.
