WARNING — Handling and manipulation of microorganisms which are potentially hazardous requiresa high degree of technical competence and may be subject to current national legislation andregulations. Only personnel trained in microbiological techniques should carry out such tests.Appropriate practices for disinfection, sterilization and personal hygiene must be strictly observed.This International Standard specifies a method of evaluating the antibacterial activity of antibacterial-treatedplastic products (including intermediate products).NOTE It may also be suitable for other non-porous materials.It is not intended to be used to evaluate the effects and propagation of bacteria on plastics withoutantibacterial treatments. ISO 846 [6] describes tests to evaluate the effects and propagation of bacteria onplastics, which are different from those covered by this International Standard. Those who are interested arereferred to ISO 846:1997, method C.Secondary effects of antibacterial treatments, such as the prevention of biodeterioration and odour, are notcovered by this International Standard, which is not intended to be used or referenced as a method todocument or claim biodegradability of plastics. For biodegradation, refer to ISO 14851, ISO 14852 andISO 14855 (see the Bibliography) and related standards.This International Standard does not concern plastic building materials, such as PVC or composites, unlessthey act in the same way as treated articles.Any results obtained with this International Standard should always refer to this standard and the conditionsused. Results obtained with this International Standard indicate antibacterial activity under the specifiedexperimental conditions used herein, and do not reflect activity under other circumstances where a variety offactors, such as temperature, humidity, different bacterial species, nutrient conditions, etc., have to beconsidered. A minimum diffusion of the antibacterial agents/chemicals into the test inoculum is necessary withthis procedure.It is recommended that workers consult ISO 7218.
