The work of preparing International Standards is normally carried out through 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, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IsO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISo Council. They are approved in accordance with iSO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 8232 was prepared by Technical Committee ISO/TC 72, Textilemachinery and allied machinery and accessories. Annex A forms an integral part of this International Standard. Annex B is for infor- mation only. International Organization for Standardization, 1988 ?

For safetyrequirements concerning the industrial use of these machines, reference shouid be made to the appropriate regula- NOTES tions. 1For a given machine, the cycles chosen should be the sameforthe whole series of tests. 2 Definitions 2 For a machine working with a solvent other than perchlorethylene, only the "manufacturer" cycle is used. 2.1 closed-circuit dry-cleaning machine: Machine with integral systems of solvent recovery necessary for all phases of cleaning, to give a clean, dry and deodorized load, avoiding, Table 1 - Theoretical test cycle with perchlorethylene automatically and without regeneration, Theoretical cycle Operation any leakage between the atmosphere of the plant and min the machine surroundings (including inside parts cf the Washing 10 machine and piping), 22 Liquid emptying time Spin time any evacuation of waste (except water, free of solvent Drying and deodorization 1) 15 - 20 - 25 undissolved in the separator siphon). 1) Time set according to the type of machine tested.
