3.3.2 Corrosion protection.
3.3.2.1 Corrosion protection (humidity cabinet). The oil shall protect metal to the extent
that no more than a combined total of three corrosion dots, none of which exceed 1 millimeter
(mm) in diameter, occur on the panels (see 4.2.2.2.1).
3.3.2.2 Corrosion protection (vapor phase). The oil shall protect metal to the extent that
no more than a combined total of three corrosion dots, none of which exceed 1 mm in length,
width or diameter, occur on the panels (see 4.2.2.2.2).
3.3.2.3 Corrosion protection (vapor phase after evaporation). The oil shall protect metal
to the extent that no more than a combined total of three corrosion dots, none of which exceed
1 mm in length, width or diameter, occur on the panels (see 4.2.2.2.3).
3.3.3 Acid neutralization. The oil shall protect metal to the extent that no more than a
combined total of three corrosion dots, none of which exceed 1 mm in length, width or diameter,
occur on the panels (see 4.2.2.3).
3.3.4 Water displacement and water stability. The oil, after storage in contact with
water, shall satisfactorily displace water as evidenced by the absence of rust, mottling, or surface
stains on the panels (see 4.2.2.4).
3.4 Interface requirements.
3.4.1 Copper strip corrosion. The oil shall not tarnish the copper strip exceeding the
value of 2c on the ASTM D130 Copper Strip Classification scale (see 4.2.3.1).
3.4.2 Metal protection (immersion). The oil shall not produce corrosion effects as shown
by weight gain or loss more than as specified in Table II (see 4.2.3.2).
