NOTES:
1/
All qualification tests shall be conducted on stored coatings after one year of storage. If all other
requirements are met, qualification approval will be granted prior to receiving these results, but
qualification approval will be withdrawn if results indicate non-compliance with this requirement
(see 3.10).
2/
Shall be visually compared to company color card or to FED-STD-595 designated color (see 3.3).
3/
Combined A+B for test.
4/
Mixed A+B for Classes 10a, 10b, 10c, 11, and 12.
4.5.1 Pot life (except Types VIII and VIIIa). The coatings of the coating system shall be mixed from the
components, in accordance with the manufacturer's instructions, in a container so as to result in approximately 3.78
liters (1 gallon) of finished material. For routine testing, ambient conditions above 21 °C (70 °F) and 50 percent
relative humidity shall be satisfactory. For referee tests, 21±3 C (70±5 F) and 80±10 percent relative humidity
shall prevail. The time between mixing and the loss of adequate brushing and spraying properties shall be
determined (see 3.8, 4.5.7, and 4.5.8). Record the actual temperature, humidity, and the time of loss of adequate
brushing and spraying properties. For reduced temperature coating systems (Grades A and B), pot life of individual
mixed coatings shall be determined at the lower end of the temperature range or as directed by the coating
manufacturer. The pot life shall be a minimum of 1 hour in accordance with the requirements of 3.12.
4.5.1.1 Condition in container. When tested in accordance with Method 3011.3 of FED-STD-141, the
individual components shall be readily broken up with a paddle to a smooth uniform consistency. When tested as
specified in table V, paint, mixed from components aged at least 1 year in ambient laboratory conditions, shall be as
specified in 3.10. When tested in accordance with ASTM D562, the consistency of the paint, mixed from the aged
components, shall be as specified in 3.10.
4.5.1.2 Accelerated storage stability. After exposure of components A and B to a temperature of 60 °C
(140 °F) for a period of 14 days, previously unopened containers of components A and B shall be prepared for
4.5.2 Immersion resistance panel preparation of all coatings.
a. The coating systems shall be applied as specified in the manufacturer's instructions and shall completely
coat three abrasive blasted, hot rolled, mild steel plates (minimum size: 150 by 300 by 3 millimeters (6 by 12 by
0.125 inch) (nominal)). The blast pattern shall be not greater than 0.08 millimeter (3 mils) (nominal) depth for
coating systems having 0.13 millimeter (5 mils) or more dry film thickness (DFT) and 0.04 millimeter (1.5 mils) for
systems having less than 0.13 millimeter (5 mils) DFT. The test panels shall have all mill scale, rust, and rough
edges completely removed and prepared to applicable surface profile in accordance with SSPC SP-10 before
coating.
