Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). 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, 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 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 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 subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 16145-4 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 8, Ship design.

ISO 16145 consists of the following parts, under the general title Ships and marine technology — Protective coatings and inspection method:

• Part 1: Dedicated sea water ballast tanks
• Part 2: Void spaces of bulk carriers and oil tankers
• Part 3: Cargo oil tanks of crude oil tankers
• Part 4: Automated measuring method for the total amount of water-soluble salts

The following part is under preparation:

• Part 5: Assessment and calculating method for damaged coating areas of ballast tanks

Introduction

The ISO 16145 series addresses qualified coating and inspection works in accordance with the requirement 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 of surface preparation and coating in accordance with the coating manufacturer's 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.

1 Scope

This part of ISO 16145 describes the characteristics of an automated measuring method by using a conductivity meter for the assessment of the total surface density of various water-soluble salts on steel surfaces prior to coating applications for dedicated sea water ballast tanks, void spaces of bulk carriers and oil tankers, and cargo oil tanks of crude tankers in compliance with PSPC stipulated by IMO Res.MSC.215(82), IMO Res.MSC.244(83), and IMO Res.MSC.288(87).

This method describes a procedure for rapid evaluation of the surface of steel for the presence of ionic contamination by determining the total concentration of water-soluble ionic contaminants by means of a conductivity test.

This method may be equivalent to ISO 8502-9:1998.
