1.2 The procedures are as follows:
5. Test Panels
Procedure A—Conversion coatings (phosphates, chromates,
etc.) 5.1 Prepare the test panels from rust and stain-free cold-
rolled steel as described in 5.2, 5.3, 5.4, and Table 1. The
Procedure B—Vapor degreasing
Procedure C—Solvent brushing panels shall be made to a size and thickness as agreed upon
between the purchaser and seller. Edges shall be smooth and
Procedure D—Solvent wiping
Procedure E—Alkaline cleaning corners rounded. The steel may have been coated at the mill
with a suitable rust preventive compound for protection during
1.3 The values stated in SI units of measurement are to be
regarded as the standard. The values given in parentheses are shipment and storage. However, long-term steel storage with
oil on the surface may cause an oil/steel reaction known as oil
for information only.
1.4 This standard does not purport to address the safety stain. Since such stains inhibit chemical bonding, the steel
selected for panels shall be free of oil stain and other visible
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and processing variation caused by pickling or annealing.
