BS EN 4170:2007

This standard BS EN 4170:2007 Aerospace series. Paints and varnishes. Test method for measurement of resistance to cold crack temperature cycle is classified in these ICS categories:

• 49.040 Coatings and related processes used in aerospace industry

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.
