The work of preparing International Standards is normally carried out throu
24、gh ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collabora
25、tes closely with the International Electrotechnical Commission (IEC) on all 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 Standar
26、ds. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of th
27、is document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

When requirements of this type-C standard are different from those which are stated in type-A or -B standards, the requirements of this type-C standard take precedence over the requirements of the
31、other standards for machines that have been designed and built according to the requirements of this type-C standard.

32、 1 Scope This part of ISO 8230 specifies safety requirements for dry-cleaning machines that use a combustible solvent (CS), as defined in ISO 8230-1, as their cleaning medium. It is applicable to such dry-cleaning machines, within the scope of ISO 8230-1, when they are used as intended and under con
33、ditions of misuse that are reasonably foreseeable by the manufacturer. This part of ISO 8230, in conjunction with ISO 8230-1, deals with all significant hazards, significant hazardous situations and significant hazardous events that have been identified as being significant to the types of machines
34、covered by this part of ISO 8230 and which require specific action by the designer or manufacturer to eliminate or reduce the risk. It deals with the following significant hazards specific to the use of CS: hazards related to the entire dry-cleaning machine (electrical hazards, explosion hazards); h
35、azards relating to the machine (combustible solvent emission, explosion hazards during the cleaning phase, explosion hazards during the drying phase); hazards relating to the distilling equipment (combustible solvent emission, explosion hazards). This part of ISO 8230 applies to machines manufacture
