12、ctures.Edit this guide specification for project specific requirements by adding, deleting, or revising text. For bracketed items, choose applicable items(s) or insert appropriate information.Remove information and requirements not required in respective project, whether or not brackets are present.

13、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 organization designation and telephone number, is on the Internet.Recommended changes to a UFGS should be submit

14、ted as a Criteria Change Request (CCR).*PART 1 GENERAL*NOTES: The protective metallic coating systems listed have limited applicability at this time. Some states and municipalities have stringent regulations governing the use of architectural coatings containing volatile organic compounds (VOC). Man

15、y of the coating systems found in Section 09 97 02 PAINTING: HYDRAULIC STRUCTURES, do not meet VOC regulations in some regions of the country.The coating systems contained herein are suitable substitutes for the paint systems in Section 09 97 02and may be used should air pollution regulations so dic

16、tate. It should be noted that some of the sealer SECTION 09 97 01.00 10 Page 3Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-and paint coats recommended in this guide may also not be VOC-compliant in some regions of the country.The use of metallizin

17、g system 6-Z-A is advocated for use on steel immersed in very turbulent, ice- and debris-laden fresh waters. Exposures such as this may erode and cause total failure of the standard abrasion-resistant paint systems found in Section 09 97 02 in as little as 1 year. System 6-Z-A, with appropriate seal

18、ing and top coating, will provide superior protection for this type of severe service.The use of metallizing system 8-A is endorsed for high temperature atmospheric exposures. Paint coatings do not generally perform as well as thermal spray coatings of aluminum for high temperature exposures such as

19、 stacks. The use of metallizing system 6-Z-A is recommended for use as a zebra mussel repellent coating where the use of such a coating is deemed necessary. System 6-Z-A is longer lived and has a lesser environmental impact than conventional copper-containing antifouling coatings. The use of this gu

20、ide specification should be limited to work described in this note.The metallizing systems described in this document are intended for corrosion protection of cold and hot rolled steel. Metallizing systems described herein are not intended for use on stainless steel, aluminum, bronze, copper, plasti

21、c, rubber, wood, masonry, and painted surfaces. Coating systems contained herein should not be specified for potable water tank interiors, moving parts or wear surfaces of machinery, or for surfaces subject to strong acids or bases.For further technical assistance contact:US Army Construction Engine

37、STEM DESCRIPTIONPrepare a thermal spray Job Reference Standard (JRS) at the jobsite prior to the onset of production work. The JRS is used at the initiation of the contract to qualify the surface preparation, thermal spray application, and sealing processes and also serves as a standard of quality i

38、n case of dispute. To prepare the JRS, a steel plate of the same alloy as the surfaces to be metallized measuring 600 x 600 x 10 mm 2 feet x 2 feet x 3/8 inch shall be solvent and abrasive blast cleaned in accordance with the requirements of the contract. The abrasive blast media and equipment shall

39、 be those that will be used on the job. One-fourth of the JRS plate shall be masked with sheet metal and the thermal spray coating applied to the unmasked portion of the plate. The thermal spray coating shall be applied using the same equipment, approved wire, and spray parameters to be used on the

40、job. Operate the gun in a manner substantially the same as will be used on the job. The approximate traverse speed and standoff distance during spraying shall be measured and recorded. Once the JRS is qualified, the operating parameters shall not be altered, except as necessitated by the requirement

41、s of the job. Two-thirds of the thermal spray coated portion of the JRS shall be sealed in accordance with the requirements of the contract. One-half of the sealed area shall be painted in accordance with the contract if applicable. Apply the sealer and paint using the same paint spray equipment tha

42、t will be used for production. The prepared JRS shall be preserved and protected in such a manner that it remains dry and free of contaminants for the duration of the contract. The surface cleanliness, blast profile shape and depth, thermal spray appearance, thickness, and adhesion, and sealer and p

43、aint thicknesses shall be determined by the Coating Inspector in accordance with the contract requirements and recorded.1.4.1 General RequirementsPerform the work in accordance with the requirements of 29 CFR 1910, 29 CFR 1926, EM 385-1-1, and other references as listed herein.
