1.3.6 Substrate metal

Metal in the form of sheet, coil, cut lengths. strip, extruded sections, tube, forgings or

castings prior to surface treatment.

1.4 ATMOSPHERIC CLASSIFICATIONS

This Standard specifies six atmospheric classifications A. B. C. D, E and F based on the severity of the environment.

NOTE: A detailed description of each of the atmospheric classitcations is given in Appendix G to facilitate determination of the

appropriate category that applies to a particular set of environmental circumstances.

Mild Interior (Atmospheric classification: Vc’rv low) Environments in this category are most commonly found inside heated or

airconditioned buildings with clean atmospheres.

Category B: Moderate liifrrior (Atmospheric classification: Low)

Environments in this category include dry, rural areas, as well as other regions remote from the coast or sources of pollution and unheated or non-airconditioned buildings where condensation may occur.
