The work of preparing International St

8、andards 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, governmental and non-governmental, in liaison with ISO, also

9、 take part in the work. ISO collaborates 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 committee

10、s is to prepare International Standards. 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 possib

11、ility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 16145-3 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 8, Ship design. ISO 16145 cons

14、ts of IMO PSPC. Technical Committee ISO/TC 8, Ships and marine 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

15、 of surface preparation and coating in accordance with coating 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 applica

16、tors in applying IMO PSPC in the new building stage. ISO 2012 All rights reserved v Ships and marine technology Protective coatings and inspection method Part 3: Cargo oil tanks of crude oil tankers 1 Scope This part of ISO 16145 specifies a method of protective coatings and its inspection of cargo

17、oil tanks for crude oil tankers of not less than 5 000 tones deadweight, which are contracted for new building on or after 1 January 2013; or in the absence of a building contract, the keels of which are laid or which are at a similar stage of construction on or after 1 July 2013; or the delivery of

18、 which is on or after 1 January 2016. NOTE A crude oil tanker is an oil tanker engaged in the trade of carrying crude oil. This part of ISO 16145 applies to crude oil tankers and crude oil/product carriers as defined in items 1.11.1 or 1.11.4 of the Supplement to the International Oil Pollution Prev
