Isang Paunang Salita
ISO (International Organization para sa Standardisasyon) ay isang pandaigdigang alyansa ng mga pambansang pamantayan katawan (Mga katawan ng miyembro ng ISO). Ang pagbuo ng mga internasyonal na pamantayan ay karaniwang isinasagawa sa pamamagitan ng ISO teknikal na komite. Ang bawat institusyon ng miyembro na interesado sa isang paksa kung saan ang isang teknikal na komite ay itinatag ay may karapatang kumatawan sa komite. Ang pamahalaan at mga di pampamahalaang internasyonal na organisasyon na nakikipag ugnayan sa mga organisasyon ng standardization ay kasangkot din sa gawaing ito. ISO ay gumagana nang malapit sa International Electrotechnical Commission (IEC) sa lahat ng bagay ng electrical standardization.

International standards are drafted according to the rules given in Part 2 ng Direktiba ng ISO / IEC.

Ang pangunahing tungkulin ng komite ng teknikal ay upang bumuo ng mga internasyonal na pamantayan. Draft international standards adopted by the Technical Committee will be circulated to member bodies for voting. Ang paglalathala bilang isang internasyonal na pamantayan ay nangangailangan ng pag apruba ng hindi bababa sa 75% ng mga miyembrong institusyon.

ISO 15711 was developed by Technical Committee ISO/TC 35, Mga pintura at barnis, Subcommittee SC 9, General test methods for paints and varnishes.

ISO 15711-2003 “Determination of Cathodic stripping resistance of paints and varnishes exposed to seawater”

Panimula
This standard describes two methods for determining the ability of paints or other organic coatings applied to metal substrates to withstand cathodic debonding. These methods can also provide a basis for comparing specific coatings. The test conditions are more severe than those that might be encountered under normal conditions and therefore may accelerate coating failure. Testing is recommended for at least 26 mga linggo, so these methods are not suitable as a means of achieving quality control.

The method is applicable to coatings used to protect ships and structures exposed to seawater. Method A is based on procedures developed and evaluated by the COIPM (International Standing Committee for the Protection of Malin Materials).

Test results may be influenced not only by the performance of the coating system under test, but also by the nature and preparation of the substrate, the method of application of the coating system, at iba pang mga kadahilanan.

1 Saklaw
This standard describes two methods for determining the ability of paints or other organic coatings applied to metal substrates to withstand cathodic debonding when the surface coating may contain or develop discontinuities. These methods are suitable for coatings that are exposed to Marine water, such as those applied to ships or Marine structures. They are not suitable for assessing the ability of coatings to withstand cathodic debonding on terrestrial structures.

Method A involves the use of a cathodic protection circuit where the electrode potential of the test substrate is controlled by a constant potential.

Method B involves the use of a sacrificial anode attached to the test substrate. This reflects the practical method of cathodic protection commonly used on ships.

3.1 Cathode debonding
Failure of bonding between the coating and the metal surface, which is directly attributable to cathodic protection conditions and is often caused by defects in the coating system, such as accidental damage, imperfect application, or excessive coating permeability
