14、, and by SSPC.Definition of a SpecificationA coating specification is a document that details themandatory technical requirements of work involving theuse of protective coatings. It includes requirements forthe quality of materials to be used during a protectivecoating application and the work to be

15、 accomplished.The general objective of the coating specification is toensure that the owner or purchaser receives the finishedwork product that is desired. This is accomplished byproviding a detailed definition of work to be done in awell-designed specification.Without a well-designed protective coa

16、ting specification,problems such as unrealistic bidding, disputes of specificrequirements, inappropriate materials or workmanship,delays in completing the work, costly change orders, andincreased costs, are likely to occur. Specifications areconcise and specific, and contain essential informationand

17、 requirements.There are several objectives for preparing a protectivecoating specification. These include, but are not limitedto, the following: To obtain specific protective coating products or theirequals; To assure quality materials and workmanship; To determine inspection requirements; To assure

18、 timely completion of work; To avoid disputes; To obtain reasonable costs that reflect the specifi-cation requirements; To avoid costly change orders and claims; To meet safety, environmental, and regulatoryrequirements of the protective coating operation; and To assure suitable coating systems are

19、applied to thecorrect equipment.General Specification CharacteristicsThe following topics are frequently included in the firstpart of a protective coating specification, not necessarilyin the order as discussed in subsequent paragraphs. Scope of Work: A summary is used at the beginningof a specifica

20、tion to state the scope and purpose ofthe work. It provides general information and notspecific items that are described elsewhere in otherspecifications. A title is sometimes adequate for thispurpose. Reference Section: The reference section lists alldocuments to be used in conjunction with the spe

21、cifi-cation. No reference is made to standards ortechnical specifications that are not part of thespecification requirements. Generally, only onestandard method is referenced for each requirement,although alternative methods are often available.These documents might include, but are not limitedto, t

Submittals Section: Documents or samples to besupplied by the coating contractor are normallyspecified in this section. Thes

26、e might include thefollowing:Samples of coatings to be used ;Drawdown films of these coatings;Coated reference panels ;Certificates of conformance or performance ;Manufacturers product data sheets and appli-cation instructions;Material safety data sheets ;Contractors projected schedule or work plan

27、;Contractor certification (such as SSPC 1, 2, 3 orequivalent)Contractors QC program and procedures; andContractors inspector training and certification.The submittals are usually kept to a minimum andare not always utilized unless specified by the owneror purchaser in order to accomplish the work. Q

28、uality Assurance Section: This section details allitems deemed necessary for quality assurance. Thiscan include requesting qualifications of the contractorand his personnel, certification of the contractor andpersonnel, and field sampling. It frequently includes aproposed inspection plan as a submit

29、tal, because thecontractor might be responsible for inspection as wellas for quality of the work. Normally, the contractor isalso responsible for meeting all applicable regula-tions as well as the owners working rules and safetystandards. Prejob Visit and Conference: Many specificationsrequire a job

30、site visit and conference to review workprocedures and standards. Delivery, Storage, Handling, and Disposal Section:Detailed in this section are requirements concerningdelivery, storage, and handling of products to beused. Collection, storage, and disposal of wastematerials and abrasive debris are a

31、lso detailed. Site Conditions Section: Conditions at the job sitethat can affect the work are defined in this section orin other contract documents. These conditions caninclude utility availability, safety, environmental, andpersonnel considerations. Any potentially hazardousmaterials or operations

32、are normally noted. Failureto note site conditions in the specification can resultin costly change orders. Resolution of Conflicts: A procedure for resolvingconflicts in the specification, references, or productmanufacturers instructions is normally stated.Product SpecificationThis portion of the sp

33、ecification defines the requirementsfor protective coating products to be employed in thework. Protective coating products can be specified bybrand name, performance criteria, or qualified productslist. When specific brand names are listed, it is commonpractice to provide the coating contractor with

34、 a choice byspecifying two or more products.All protective coatings in a single system are usuallysupplied by the same manufacturer. Color requirementsare typically specified in this section.Project ExecutionThe execution section details surface preparation andapplication of protective coatings. Sur

35、face preparation isa vital factor in achieving long-term durability of the coat-ing system. Surface preparation is defined by industrystandards and can include hand/power tool cleaning,abrasive blasting, and hydroblasting, among others, or acombination of different techniques. If an abrasive isused,

36、 the owner generally specifies the type. However,depth of anchor pattern is usually specified in the coatingmanufacturers data sheets. The owner also specifiesany limiting conditions such as requirements for dust,debris, and overspray control, limiting schedules forabrasive blast cleaning or coating

37、 application, and anyother limitations affecting the work.The protective coating systems to be used for carbonsteel piping, vessels, tankage, or other equipmentexposed to the atmosphere are typically specified, alongwith the level of surface preparation, coating material,number of coats, dry film th

38、ickness, and finish color.Other protective coating systems for use under insulationor fireproofing, at elevated equipment operating temper-atures, for safety identification, below grade, or water,and other environments or situations are also specified.Protective coating systems are frequently listed

39、 in tabularform within or at the end of the specification.At times, the owner specifies that hot-dip galvanizing besubstituted for protective coating systems, especially forhand rails, stairs, ladders, safety cages, or other struc-tures. As appropriate, galvanizing is sometimes specifiedfor beams an

40、d columns. The standards that are to beused for galvanizing applications are usually included inthe reference section of the specification and can includeASTM A 123 4 and ASTM A 780. 5NACE 80200/SSPC-TR 44The limitations on weather or other conditions that mightadversely affect the work are normally

41、 defined by theowner in the specification or other contract documents.Such limitations can include temperature, humidity, andwind. When limits defined vary from those recommendedby the coating manufacturer, the contractor is typicallyresponsible for resolving this problem with the owner.Purchased eq

42、uipment, such as vessels, pumps, rotatingmachinery, valves, and other equipment items are some-times specified to be prime coated in the shop prior tofield delivery . Repair and topcoat systems are included inthe specification in the event such prime-coated equip-ment is damaged and/or requires topc

43、oat in the field.This section also includes those materials the owner doesnot want coated, unless otherwise specified, such as: Stainless steel Galvanized steel Nonferrous metals Thermal insulation jacketing or covering Concrete PlasticsShielding or masking is frequently required by the ownerto prot

44、ect sensitive equipment, such as electronic equip-ment, gauge glasses, valve stems, machined surfaces,equipment identification labels, lighting fixtures, compres-sors, pumps, electric motors, or other equipment, fromabrasive debris and dust and from overspray.When repairs are required, the contracto

45、r typicallyprepares a repair procedure that can contain surfacepreparation, type and number of coats, and applicationtechniques. This normally includes purchased equip-ment. These repair procedures are submitted to theowner for approval.InspectionOwner inspection requirements are normally defined in

46、this section. This has been accomplished by referencingaccepted industry quality criteria test methods as avail-able from NACE, SSPC, ASTM, or others. Based onthese requirements, the contractor submits the inspectionplan discussed previously, and informs the owner whenparticular inspection points ar

47、e reached and available.Inspectors are typically certified by the NACE CoatingInspector Certification Program or equivalent. It is usuallyspecified that the owners inspector has full access to allwork.Owners frequently request participation of the ownersinspector in specific areas of coating applica

48、tion includingbut not limited to: Coating contractors recordkeeping the NACECoating Inspectors Logbook 6 and The Inspection ofCoatings and Linings 7 contain information and formsfor accurate and precise recordkeeping. Environmental conditions such as temperature,humidity, wind, direct sunlight, rain

49、, or other environ-mental conditions during storage of coating mater-ials, surface preparation, application, and curing. Surface preparation cleaning equipment, operationof equipment, degree of cleaning, and anchor pat-tern, if specified. Application storage of materials, mixing, appli-cation equipment, application, wet film thickness,dry-film thickness, and appearance.
