    1、Designation: D5065 17Standard Guide forAssessing the Condition of Aged Coatings on SteelSurfaces1This standard is issued under the fixed designation D5065; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision.

    2、A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide describes general procedures for conductinga detailed assessment of the condition of aged coatings on steelstructures and

    3、the extent of rust breakthrough of the coatedsurface. Additional assessment may be required to supportcoating failure analyses or other job specific needs.1.2 This guide does not address determining the structuralcondition of a steel substrate. It provides procedures todetermine the percent of the s

Summary

    10、of Practice3.1 This practice for assessing the condition of coatingsconsists of identifying general types of components of astructure and assessing each separately for commonly occur-ring modes of coating deterioration and substrate rusting usingvisual guides and evaluation tools. A form for recordi

    11、ng theresults of the assessment procedure (Fig. 1) is provided.4. Significance and Use4.1 Assessment of the condition of aged coated surfacesstrengthens decisions on when coating maintenance isrequired, aids in the selection of effective coating maintenanceprocedures, and provides a means to charact

    12、erize performanceof coating systems. SSPC Technology Update No. 3 discussesthe risks associated with selecting overcoating as a mainte-nance strategy, particularly without performing visual assess-ments and evaluating the physical properties of the existingcoating system(s) described in Section 5.5.

    13、 Procedure5.1 Survey the structure to (1) determine the general typesof unique components (for example, for fuel tanks the compo-nents may be shell, roof, ladders, and piping) and the service1This guide is under the jurisdiction of ASTM Committee D01 on Paint andRelated Coatings, Materials, and Appl

Rate the condition of thecoatings using the appropriate ASTM visual standard for rus

Record therating in

    22、the appropriate column of the report form for eachcomponent. Determine and record the type of peeling, forexample, intercoat delamination. Rate the condition in enoughareas to ensure that for each component the coating evaluationis representative of the condition over the entire structure. Ifadditio

Remove apparently intact coatings usingchemical strippers or closely spaced parallel knife cuts. Forstructural steel, determine the type of previous surface prepa-

Record themeasured thicknesses.5.5 If a measure of coating adhesion is desired, use one ofthe procedures described in Test Methods D3359, D4541,orD6677. Determine coating adhesion in enough ar

Record theadhesion rating or value, the procedure and equipment used.NOTE 3The number of areas that coating thickness and adhesion ismeasured will depend upon the desired precision of the measurement.More measurements would be made on structure
