SSPC: The Society for Protective Coatings

Material and Preparation Requirements for

Steel Test Panels Used to Evaluate

the Performance of Industrial Coatings

1. Scope

This standard contains requirements for steel panels used

to perform tests for evaluation of various performance char-

acteristics of protective coatings applied to steel substrates.

Panels meeting requirements of this standard may be used

for tests including, but not limited to, natural and accelerated

exposure in or out of the laboratory; tests to determine resis-

tance to various chemicals, impact, and abrasion; and tests

to characterize properties such as color, gloss, adhesion, and

hardness. Requirements for steel composition, panel dimen-

sions, surface preparation, ambient conditions for application

and cure of coatings, and location and dimensions of scribes

on coated panels are included.
