Description / Abstract:
This International Standard specifies quantitative test methods
to determine the antibacterial activity of all antibacterial
textile products including nonwovens.
This International Standard is applicable to all textile
products, including cloth, wadding, thread and material for
clothing, bedclothes, home furnishings and miscellaneous goods,
regardless of the type of antibacterial agent used (organic,
inorganic, natural or man-made) or the method of application
(builtin, after-treatment or grafting).
Based on the intended application and on the environment in
which the textile product is to be used and also on the surface
properties of the textile properties, the user can select the most
suitable of the following three inoculation methods on
determination of antibacterial activity:
a) absorption method (an evaluation method in which the test
bacterial suspension is inoculated directly onto specimens);
b) transfer method (an evaluation method in which test bacteria
are placed on an agar plate and transferred onto specimens);
c) printing method (an evaluation method in which test bacteria
are placed on a filter and printed onto specimens).
The colony plate count method and the ATP (ATP = Adenosine
Tri-phosphate) luminescence method are also specified for measuring
the enumeration of bacteria.
