Designation:D 5161 04Standard Guide forSpecifying Inspection Requirements for Coating and LiningWork(Metal Substrates)1This standard is issued under the fixed designation D 5161;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(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide is intended to aid the coating specificationwriter in selecting and specifying the appropriate inspectionrequirements.It indicates the inspection requirements that maybe employed for each of four service environments includingmild,moderate,severe,and immersion(see Table 1).1.2 In order to aid the user in determining when to specifyinspection requirements,a relationship between the conse-quence of failure and the suggested level of inspection isdemonstrated(see Fig.1).1.3 It is not the intent of this guide to address the selectionof protective coating systems,to specify surface preparationand application requirements,or to be a referenced documentin a specification.2.Referenced Documents2.1 ASTM Standards:2D 1186 Test Methods for Nondestructive Measurement ofDry Film Thickness of Nonmagnetic Coatings Applied toa Ferrous BaseD 1400 Test Method for Nondestructive Measurement ofDry Film Thickness of Nonconductive CoatingsApplied toa Nonferrous Metal BaseD 3276 Guide for Painting Inspectors(Metal Substrates)D 4285 Test Method for Indicating Oil or Water in Com-pressed AirD 4414 Practice for Measurement of Wet Film Thickness byNotch GagesD 4417 Test Methods for Field Measurement of SurfaceProfile of Blast Cleaned SteelD 4940 Test Method for Conductimetric Analysis of WaterSoluble Ionic Contamination of Blasting AbrasivesD 5162 Practice for Discontinuity(Holiday)Testing ofNonconductive Protective Coating on Metallic SubstratesE 337 Test Method for Measuring Humidity with a Psy-chrometer(the Measurement of Wet and Dry-Bulb Tem-peratures)2.2SSPC Standard:31This guide is under the jurisdiction of ASTM Committee D33 on ProtectiveCoating and Lining Work for Power Generation Facilities and is the directresponsibility of Subcommittee D33.04 on Quality Systems and Inspection.Current edition approved Jan.1,2004.Published February 2004.Originallyapproved in 1991.Last previous edition approved in 1996 as D 5161 96.2For 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 The Society for Protective Coatings(SSPC),40 24th St.,6thFloor,Pittsburgh,PA 15222-4656.TABLE 1 Inspection RequirementsSuggested InspectionRequirementsService EnvironmentsMildModerateSevereImmersionPre-Surface Preparation:Visual for contaminantsXXXXVisual for surfaceanomaliesXXSurface Preparation:Air supply forcontaminantsXXAbrasives for type andcleanlinessXXAmbient conditions anddew pointXXSurface anomaliesXXDegree of cleanlinessXXXXProfileXXXVisual final forcontaminationXXCoating Application:MaterialsXXXMixingXXEquipmentXXXAir supply forcontaminantsXXXAmbient conditions anddew pointXXWet film thicknessXXIntercoat parametersXXXAppearance betweencoatsXXDry film thicknessbetween coatsXXFinal Acceptance:AppearanceXXVisual runs and sagsXXXVisual holidays andpinholesXXDry film thicknessXXXHoliday testsXRepairsXXFinal cureXX1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.SSPC VIS 1-89 Visual Standard for Abrasive Blast CleanedSteelSSPC VIS 3 Visual Standard for Power-and Hand-ToolCleaned Steel3.Terminology3.1 Service Environments Terms are as follows:3.1.1 mild serviceindoor or protected outdoor areas notsubject to rain,dew or corrosive elements,or both.3.1.2 moderate serviceareas subject to weather awayfrom coastal or corrosive industrial environments,or both.3.1.3 severe servicecorrosive/erosive environments in-cluding coastal salt laden atmosphere,industrial atmosphere,and high intensity sunlight.3.1.4 immersion servicewetted surfaces of tanks,contain-ers,pits,etc.and surfaces that are normally wet with conden-sation or exposed to other corrosive environments.4.Significance and Use4.1 The requirements for inspection should be addressed inall protective coating and lining work specifications.4.2 This guide may be used by specification writers whenselecting and establishing the inspection requirements forcoating and lining specifications.4.3 The instructions for using this guide are as follows:4.3.1 Identify the service environment for the coating orlining system being specified.Read down the column under theappropriate service environment in Table 1.Suggested levels ofinspection listed on the left are identified with Xs.5.Inspection Requirements5.1 Pre-Surface Preparation:5.1.1 ContaminantsVisually verify that oil and grease ar
