This standard describes a procedure of ageing to assess the resistance of a coated panel (metallic or organic substrate) to a temperature cycle (cold, hot, hot and wet) for aerospace purposes. This test deals with the assessment of the capability of the paint to support modification of internal stresses without any crack formation, peeling or other defects due to modification of the mechanical properties of the paint system.
