855.05 Coating Systems For Structural Steel.
Requirements". Components of each batch will be sampled at the project level or fabrication plant for selective verification testing of those parameters listed in the Procedure for List III -1.
b.The right is reserved to inspect, resample, and retest any previously approved material at any time when it is deemed expedient by the Engineer.
c.Materials stored in accordance with the recommendations of the manufacturer may be used at any time up to the expiration date printed on the material c ontainer. Materials not used prior to the expiration date must be retested and reapproved before their use will be allowed.
855.05 Coating Systems For Structural Steel.
The Department has established several types of coating systems according to the antici pated environmental conditions as well as the required surface preparation. The list is divided into various coating systems which have been approved for each of these types through actual field use or field and/or laboratory tests conducted by approved Go vernmental Agencies. These are multiple coat systems of production run materials from various coating manufacturers. This list is found in the Department's "Materials, Sources, and Devices with Special Acceptance Requirements" manual, List III -1. The requi rements for the use of products from this list are found in its accompanying procedure. A copy of the list and its accompanying procedure are available from the Bureau of Materials and Tests. The following will apply when the condition exists where a coati ng system, produced by a manufacturer not initially listed on List III -1, is proposed for use:
a.The manufacturer of the coating shall request that the Department approve the coating system according to the procedure referred to above.
b.In lieu of the completed field test, the manufacturer shall be required to demonstrate to the Department that the system can be suc cessfully applied.
c.Upon demonstration of a successful application, the Department may give temporary approval to the coating system unt il time allows for the system to complete a performance field test.
d.Upon successful completion of the field test, the coating system will be added to List III -1.
e.The Department will monitor the applied coating system during this interim period (un til field testing is complete) for any cracking, peeling, blistering, or loss of adhesion between the substrate or any layer which will be cause for revocation of the temporary approval. The required type of system will be specified on the contract plans f or individual projects. Contractors may select any system listed from the specified type of system. Only systems on this list shall be furnished for use. Systems are comprised of multiple products representing the various coats required. Products must be u sed with their counterparts in that system only. Mixing of products from different systems will not be allowed. The number of coats is specified on the list. Coating thickness shall be as recommended by the producer of the material with conformance checked in accordance with standard SSPC -PA2. All coatings shall be applied in accordance with the manufacturer's recommendations using spray equipment suitable for the coating unless otherwise specified. To allow ease of visual inspection, the prime coat shall b e a color to contrast the cleaned steel surface and each coat in the system shall be of a color which will contrast the other layers in contact with it. The topcoat for non -weathering steel shall be a green color matching Federal Standard 595 Chip 24272 un less otherwise specified. The topcoat for the partial painting of weathering steel shall be a brown color matching Federal Standard 595 Chip 30045 unless otherwise specified. High solids aluminum mastic coatings will not be required to be colored, unless o therwise specified.
