The work of preparing International Standards is normally carried out through ISO technical committ

8、ees. 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 collaborates closely with the Int

9、ernational 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 Standards. Draft International

10、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 this document may be the s

Technical Committee ISO/TC 8, Ships and marin

14、e technology, SC 8, Ship design has decided to standardize a coating and inspection method for the IMO PSPC series. Coating quality itself depends largely on the surface preparation and coating application. Therefore, the right application of surface preparation and coating in accordance with the co

15、ating manufacturers recommendations, including inspections at each step, are of vital importance. This part of ISO 16145 is intended to serve as a standard for ship owners, shipyards, coating manufacturers, coating inspectors and coating applicators in applying IMO PSPC in the new building stage.
