18、ms for exteriors of new Navy and Air Force steel structures, such as fuel tanks, water tanks, aboveground piping, etc.Edit this guide specification for project specific requirements by adding, deleting, or revising text. For bracketed items, choose applicable items(s) or insert appropriate informati

19、on.Remove information and requirements not required in respective project, whether or not brackets are present.Comments and suggestions on this guide specification are welcome and should be directed to the technical proponent of the specification. A listing of Technical Proponents, including their o

20、rganization designation and telephone number, is on the Internet.Recommended changes to a UFGS should be submitted as a Criteria Change Request (CCR).*NOTE: This guide specification is intended for coating of new structures and coating of existing structures where all existing coating material is be

21、ing removed to bare metal. To determine the requirements for maintenance of an existing coating, a coating inspection or coating condition survey (CCS), as described herein, should be accomplished prior to designing the coating project. Without a competent inspection, there is no reliable way to det

22、ermine the type or condition of the existing coating system. Without knowing the existing conditions, proper (effective and financially supportable) surface preparation or coating system selection cannot be made.*SECTION 09 97 13.27 Page 4Provided by IHSNot for ResaleNo reproduction or networking pe

23、rmitted without license from IHS-,-,-*NOTE: This specification is for general use on steel structures, or miscellaneous steel appurtenances, in atmospheric service (non-immersion). This includes fuel tanks, water tanks, aboveground piping, cranes, towers, etc. It should also be used for enclosed or

24、exposed structural steel in buildings such as hangars, acoustical enclosures, or other facilities where a high-performance coating system is desired. This coating system is ideal for repairing and coating of galvanized surfaces. Repair galvanizing with the zinc-rich primer, and apply general coats o

25、f intermediate and topcoat to all surfaces.*NOTE: This specification should be edited by an SSPC certified Protective Coatings Specialist (PCS) that has five or more years of experience preparing coating specifications.The designer should not alter the products and processes specified herein without

26、 thorough knowledge of the need for the changes and the implications of those changes.*NOTE: This guide specification complies with the intent of Air Force ETL 86-4, as revised on 28 April, 1999 to eliminate the “second primer coat.“ *NOTE: The metric standard for measuring coating thickness is micr

27、ons (25.4 microns=1 mil - use nominal 25 microns=1 mil). *NOTE: This specification is for an industry standard, 3 Coat, thin film, coating system that is compliant with EPA VOC regulations as of June 2000:- Epoxy coats 350 g/l 2.8 lbs/gal max. VOC- Polyurethane Topcoat 350 g/l 2.8 lbs/gal max. VOCTh

28、e designer shall review state and local, regulations and determine whether the coating in this Section complies with restrictions on volatile organic components (VOC) and other chemical constituents.*NOTE: Previous versions of this specification have included a requirement for surfaces to be abrasiv

29、e blasted to SSPC SP 7/NACE No.4, inspected, and SECTION 09 97 13.27 Page 5Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-repaired, prior to coating. That requirement has been removed from this specification, and if required for a repair project, it

30、 should be included in the structural repair Section of the project specification. Tailor the paragraph to the needs of cleaning that will be required in preparation for repairs, and note that the abrasive blasting for inspection should be accomplished in such a manner that it does not conflict with

31、 any surface condition requirements in this Section, such as creating excessive surface profile that may require excessive primer thickness. For repair projects, specify appropriate portions of the steel surfacing requirements (according to NACE RPO178) from Section 33 56 13.13 STEEL TANKS WITH FIXE

32、D ROOFS.*NOTE: For purposes of this specification, the term “maintenance coating“ refers to maintenance overcoating as opposed to complete removal of coatings and recoating. For maintenance coating designs, or to determine if maintenance overcoating is appropriate, a coating condition survey (CCS) s

33、hould be accomplished. The CCS should be accomplished by personnel from a business that routinely performs coating evaluations, and the individual investigator should be Certified by SSPC as a Protective Coatings Specialist. The CCS should be sufficiently detailed to provide all technical informatio

34、n about the coatings, and structures to be coated, required to properly design the project. At a minimum, the CCS should provide a detailed report of: 1. Existing coating conditions, including condition of coating film, and the existence of potentially hazardous substances that may impact coating ma

35、nagement (i.e. lead, cadmium, chromium);2. Analysis of remaining coating life, suitability of overcoating, and technical requirements for overcoating;3. Technical recommendations for the most cost effective management of existing coating systems, including any hazardous materials present in paint fi

36、lm; and 4. Any other information of interest to the coating system management that should be identifiable by an individual trained and experienced in the field of coating analysis, coating failure analysis, and coating design.The scope of the CCS should be tailored to the specific project, and it sh

37、ould be recognized that while multiple coating failures or deficiencies may look similar to the untrained eye, the risks of SECTION 09 97 13.27 Page 6Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-generalizing to save evaluation costs are potentiall

38、y very high. The cost of large-scale failure of the overcoating, and complete replacement of the coating system, is far more than the cost of a CCS for all but the smallest projects.The risks of overcoating can usually be avoided by designing project to remove all existing coatings to bare metal, th

39、en providing appropriate surface preparation and coating application. However, the extra costs of the coating removal, especially if containing hazardous material, along with the cost of surface preparation to SSPC SP 10 Abrasive Blast to Near-White Metal, may be exorbitant compared to the costs of

40、maintenance overcoating where the existing coating system is in fair-to-good condition.Additionally, NAVFAC Design Policy Letter DPL-09B-0001, Lead-containing Paint on Non-residential Structures of 26 Mar 92 provides guidance for managing paints containing lead and other hazardous materials in place

41、. The fact that lead was highly used as a primer is indicative of its value to the corrosion control industry. Premature removal of sound lead primer is not considered to be a good management practice.Activities should consider an annual CCS to survey all structures to be authorized for design in th

42、e coming year. When accomplished for multiple projects, the per-structure cost will decrease. By accomplishing this survey prior to design, the basis for design is fully identified.The CCS can also be a very useful tool when used to screen structures for maintenance painting requirements. A CCS can

43、be scoped to provide a general inspection of many structures to screen for near-term overcoating or recoating requirements, and subsequent investigation can be made to provide appropriate details for project planning and design.It should be pointed out that the aesthetic features of a coating do not define the coating condition; they only describe how the coating looks. Many coating systems have been replaced when only the topcoat is in need of “refurbishment.“ Li
