Scope1.1 This specifi cation covers a hot-applied coal tar paint-ing system for underground and underwater steel struct
2、ures, consisting of a primer and two hot-applied coats.1.2 This system is suitable for use on parts or structures exposed in Environmental Zones 2C (fresh water immersion), 3B (chemical, neutral), and 3C (chemical, alkaline). It has good abrasion resistance. It is also suitable for underground use.
3、It must be used with discretion for immersion in corrosive chemi-cals since the coating is dissolved by some organic solvents and attacked by oxidizing solutions.1.3 The coal tar enamel must be topcoated with coal tar emulsion when exposed to sunlight to prevent checking and alligatoring.2. Descript
4、ion2.1 This painting system consists of surface preparation by commercial blast cleaning or pickling, one prime coat, and two fi nish coats of hot-applied coal tar enamel per AWWA C 203, “Standard Specifi cations for Coal-Tar Protective Coatings and Linings for Steel Water PipelinesEnamel and TapeHo
5、t Applied.” A fi nal topcoat of coal tar emulsion is to be applied when exposed to sunlight. The AWWA enamel is recommended for potable water.3.

15、nance painting procedures, see SSPC-PA Guide 4, “Guide to Maintenance Repainting with Oil Base or Alkyd Painting Systems.”6.4 NUMBER OF COATS: Minimum of three.6.5 DRY FILM THICKNESS OF PAINT SYSTEM: Not less than the following as measured in accordance with SSPC-PA 2, “Measurement of Dry Coating Th
16、ickness with Magnetic Gages”: primer 13 to 50 micrometers (0.5-2.0 mils); second coat 760 micrometers (30 mils); fi nish coat 760 micrometers (30 mils); for the three-coat painting system 1575 micrometers (62 mils); fourth coat (when required) 250 micrometers (10 mils); for the four-coat system 1830
17、 micrometers (72 mils).7. Inspection7.1 All work and materials supplied under this specifi ca-tion are subject to timely inspection by the purchaser or his authorized representative. The contractor shall correct such work or replace such material as is found defective under this specifi cation (See
18、Note 9.1.). In case of dispute, unless otherwise specifi ed, the arbitration or settlement procedure established in the procurement documents shall be followed. If no arbitration or settlement procedure is established, then a procedure mutually agreeable to purchaser, material supplier, and contract
19、or shall be used. 7.2 Samples of paints under this painting system may be requested by the purchaser and shall be supplied upon request along with the manufacturers name and identifi cation for the materials. Samples may be requested at the time the purchase order is placed, or may be taken from uno
20、pened containers at the job site.7.3 Unless otherwise specifi ed, the sampling shall be in accordance with ASTM D 3925.8. Disclaimer8.1 While every precaution is taken to ensure that all information furnished in SSPC standards and specifi cations is as accurate, complete, and useful as possible, SSP
