However, the selected organism
42、s should contain at least one gram-positive and one gram-negative organism as the antibacterial agents may have different activities.Test strains shall be obtained from agencies of the World Federation of Culture Collection (WFCC).The bacteria species and their supply sources shall be included in th

45、ncubate in the shaking incubator (5.11) at (37 2) C for about 16 h (overnight culture). Estimate the number of bacteria with microscopic observation or other methods. Prepare physiological saline (6.5) with 1 % nutrient broth (NB) (6.2). Use this media to prepare a suspension with a bacterial concen
46、tration of (2,5 approximately 10) 105CFU/ml as test inoculum.If necessary, store the test inoculum on ice and use it within 4 h.9 Preparation of test samples9.1 GeneralTest only the components or material which are claimed to be antibacterial. If the whole footwear is claimed as antibacterial, major
47、 components, including upper, lining, insole, insock, outsole shall be tested separately.In the case where only one material of a component is claimed to be antibacterial, it shall be tested separately, if possible. Otherwise, the whole component shall be tested.Each test sample shall be at least 80
48、 % of the surface area of the component or material. If single material accounts for less than 80 %, take two main materials used in the composition of the component.The test samples can be obtained directly from the footwear raw materials.4 ISO 2013 All rights reservedBS EN ISO 16187:2013ISO 16187:
