4.4.3 Corrosion. Two specimens, 2 x 4 inches shall be prepared from each of the metals listed in
Table II. Each specimen shall be weighed to the nearest 0.1 mg, placed singly in suitable glass
jars at approximately a 45° angle, and completely covered with the paint remover. The jars shall
be loosely capped with screw type cap and placed in a suitable conditioning chamber at the
manufacturer's recommended operating temperature, for a total exposure period of 24 hours. At
the end of the exposure period, the specimens shall be removed from the conditioning chamber
and thoroughly rinsed with tap water. The specimens shall then be thoroughly rinsed with a
suitable solvent, oven dried at 375°F for one hour, desiccated for one-half hour, and re-weighed
to the nearest 0.1 mg. Pitting, etching, or weight changes exceeding the limits of Table II shall be
cause for rejection.

temperature in an oven prior to immersing the test panels; the test panels shall remain in the
remover in the oven for a period of 30 minutes. At the conclusion of the test period the test
panels shall be rinsed with a water spray (hot or cold) not exceeding 100 psi. The test panels shall
be air dried and examined for compliance with the paint removal requirements of Table I.

period, the container shall be examined for visual signs of paint remover deterioration. Any
bulging of the container due to pressure build-up or signs of deterioration of the container lining
or material separation shall be cause for rejection. The paint remover shall then conform to all the
