适用范围：This International Standard specifies procedures for detecting the presence of porosity in a protective paintsystem of any thickness on a steel or other metallic substrate. The procedures given in this InternationalStandard are based on methods using two different types of test equipment, the choice of equipmentdepending on the dry film thickness. These procedures are only applicable to the testing of electrically nonconductiveparts of a paint system.The test methods specified are mainly intended for use with new coatings, but can also be used for coatingswhich have been in service for some time. In the latter case, it is important to bear in mind that the coatingmight have been penetrated by substances in contact with the coating during service.
