ISO 6860:2006 Preview
Paints and varnishes -- Bend test (conical mandrel)
This standard was last reviewed and confirmed in 2015. Therefore this version remains current.
ISO 6860:2006 describes an empirical test procedure for assessing the resistance of a coating of paint, varnish or related product to cracking and/or detachment from a metal substrate when subjected to bending around a conical mandrel under standard conditions.
For a multi-coat system, each coat may be tested separately or the complete system may be tested.
