Designation:F113099(Reapproved 2014)An American National StandardStandard Practice forInspecting the Coating System of a Ship1This standard is issued under the fixed designation F1130;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.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 practice covers a standard procedure for inspectingthe coating system of a ships topside and superstructure,tanksand voids,decks and deck machinery,and underwater hull andboottop during drydocking.Included are a standard inspectionform to be used for reporting the inspection data,a diagramthat divides topside and superstructure individual inspectionareas,and a series of diagrams that are used to report the extentof damage to the coating system.1.2 This practice is intended for use only by an experiencedmarine coating inspector.1.3 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D660 Test Method for Evaluating Degree of Checking ofExterior PaintsD714 Test Method for Evaluating Degree of Blistering ofPaintsD772 Test Method for Evaluating Degree of Flaking(Scal-ing)of Exterior Paints2.2 Steel Structures Painting Council:SSPC-PA-2 Measurement of Dry Paint Thickness WithMagnetic Gages33.Significance and Use3.1 This practice establishes the procedure for the inspec-tion of coating systems on board ships.It contains a series ofdiagrams to be used to report the extent of damage to coatings.4.Reference Standards4.1 Extent of FailureThe overall extent of failure dia-grams(see Fig.1)and the extent within affected area diagrams(see Fig.2 and Fig.3)are used to report the area covered byvarious fouling organisms,different types of corrosion,andpaint failures.The overall extent of failure diagrams are usedfirst to group all areas where a particular type of damage hasoccurred into one contiguous block.The extent within affectedarea diagrams are then used to identify the pattern of damagewithin that contiguous block.(For example,inspection forSection I.A.General Corrosion(see Figs.4-7)and generalcorrosion appears distributed over the entire inspection area asshown by the black areas in Fig.8.)4.1.1 The first step is to draw an imaginary line that wouldenclose all of the general corrosion.This enclosure should beas small as possible.Select the diagram from the overall extentof failure diagrams that most closely approximates the en-closed area with respect to the entire inspection area.Using thegeneral corrosion example,the enclosed area(shaded area)would closely match Fig.9.4.1.2 Enter a“6”(for Diagram 6 in Fig.1)in the box nextto I.A.1.overall extent of failures in Fig.4.4.1.3 The second step is to look at only the enclosed areaand select the diagram from the extent within affected-areadiagrams that most closely identifies the pattern of generalcorrosion in the enclosed area.In this example,Fig.10(Diagram N)would be a good choice.4.1.4 Enter an“N”(for Diagram N in Fig.3)in the box nextto I.A.1.A.extent within the affected area.NOTE1Selection of diagrams is based on visual comparisons,andtherefore,different inspectors may select different diagrams.The diagramsare designed to minimize these differences and enhance reproducibility.4.2 Forms of Mechanical DamageThis reference standard(Fig.11)is a series of photographs used to identify the variousforms of mechanical damage to a coating that can lead tocorrosion.4.3 Types of CorrosionThis reference standard(Fig.12)isa series of photographs used to show examples of general1This practice is under the jurisdiction of ASTM Committee F25 on Ships andMarine Technology and is the direct responsibility of Subcommittee F25.01 onStructures.Current edition approved Jan.1,2014.Published January 2014.Originallyapproved in 1988.Last previous edition approved in 2009 as F1130 99(2009).DOI:10.1520/F1130-99R13.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from Society for Protective Coatings(SSPC),40 24th St.,6th Floor,Pittsburgh,PA 15222-4656,http:/www.sspc.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 coating damage.Included could be general corrosion,pittingcorrosion,pin-
