(Test Method)Standard Test Method for Evaluation of Painted or Coated Specimens Subjected to Corrosive Environments
Standard Test Method for Evaluation of Painted or Coated Specimens Subjected to Corrosive Environments
SIGNIFICANCE AND USE
4.1 This method provides a means of evaluating and comparing basic corrosion performance of the substrate, pretreatment, or coating system, or combination thereof, after exposure to corrosive environments.
SCOPE
1.1 This test method covers the treatment of previously painted or coated specimens for accelerated and atmospheric exposure tests and their subsequent evaluation in respect to corrosion, blistering associated with corrosion, loss of adhesion at a scribe mark, or other film failure.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

5. Apparatus
5.1 Scribing Tools:
5.1.1 Lathe Tool Type—High speed tool steel or tungsten carbide thread cutting lathe tool bit with a cutting tip having a 60°
included angle. ANSI B94.50, Style E has been found to meet these requirements. (See Fig. 1.) The tool bit is typically mounted
in a holder such as a wooden file handle to facilitate the scribing operation.
5.1.2 Pencil Type—Pencil shaped device, with a high speed tool steel or tungsten carbide scribing tip. Typically the gripping
surface is knurled. The tip may be replaceable or permanent.
5.1.3 Motorized Circular Blade—A motor fitted with a 1 to 2 mm wide circular cutting device.
5.1.4 Other Types—Other types of scribing instruments which use a knife type blade such as a scalpel, razor blade, box cutter
knife, or other sharp pointed tool are acceptable if agreed upon between the producer and the user.
5.2 Straightedge—Any straightedge of sufficient length and rigidity to guide the scribing tool in a straight line.
5.3 Paint Removal Materials—The following materials can be used to remove the coating around the scribe.
5.3.1 Spatula.
5.3.2 Knife or similar instrument—the sharpness of blade shall be agreed upon between purchaser and seller.
5.3.3 Paint Stripper or strong solvent.
5.3.4 Materials for removal by air:
5.3.4.1 Air Source—A source of compressed air capable of delivering at least 4.72 L/s (10 ft /min) at 552 kPa (80 psi).
5.3.4.2 Air Gun—An air dusting gun and nozzle combination. The following configuration has been found to be successful:
Air Consumption, Pressure, kPa Nozzle Diameter,

5.4 Scale—Any rule with 1-mm divisions.
6. Preliminary Treatment of Test Specimens
6.1 Scribed Specimens:
6.1.1 Where specified or agreed upon, prepare each specimen for testing by scribing it in such a manner that the scribe can be
exposed lengthwise when positioned in the test cabinet. This position will allow solution droplets to run lengthwise along the
scribe.
6.1.2 Scribe the specimen by holding the tool at approximately a 70 to 90° angle to the surface with the upper end of tool holder
inclined toward the operator. Position the tool so that only the tip is in contact with the surface. (See Fig. 2.) Pull the scribing tool
to obtain a uniform V-cut through the coating that is being tested. The endpoints of the scribe shall be at least 1.25 cm (0.5 in.)
from the edge of the panel. Inspect the tool frequently, using low power magnification, for dulling, chipping or wear and replace
or repair as needed. The scribe should be of sufficient length to cover the significant test area, but should not contact the edge of
the specimen. The scribe must penetrate all organic coating layers on the metal, leaving a uniformly bright line. The extent of scribe
penetration through metal coatings, such as galvanize, should be agreed upon between the producer and user. The coil coating
industry typically requires scribes to penetrate all organic coating layers but not penetrate the metal coating layers. The automotive
industry typically requires scribes to penetrate all organic and metal coating layers. The pencil type may be less effective than the
