International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
17、matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are ci

21、eaning and disinfecting protocols. The horizontal methods described in this International Standard include a surface contact method using contact plates and a swab method. The contact plate method is only applicable to flat surfaces, whereas the swab method can be used for all types of surfaces. For
22、 the sampling of large surfaces ( 100 cm2), sterile cloths or sponges can be used. This alternative method is useful for the estimation of the microbial load of surfaces. Results are often presented as hygiene scores based on the number of colony-forming units (CFU) per square centimetre present on
