Paints and varnishes - Coating systems for wind-turbine rotor blades - Part 6: Determination and evaluation of ice adhesion using centrifuge (ISO/TS 19392-6:2026)
Scope: This document specifies a method to measure ice adhesion from artificial ice on test substrates by using a centrifuge. Basic ice types are defined and test parameters for the ice removal are described to achieve reproducibility of test results for ice adhesion measurements for rotor blade coatings. This document does not intend to provide fixed test parameter to account for the diversity of relevant icing scenarios in this field of application.
NOTE In practice, ice adhesion can be determined by two different measurement principles, the centrifugal test (covered in this document) and the shear test, which differ in dynamic and quasistatic shear rates.
This test method can be used to test the adhesion of dynamic ice on the coating system of a wind turbine rotor blade under operation.

Paints and varnishes - Evaluation of defects on coated surfaces using digital image processing - Part 1: General guidance (ISO/DIS 21227-1:2026)
Scope: ISO 21227-1:2003 gives definitions for and provides guidance in the use of optical imaging systems for the quantitative characterization of defects on coated surfaces that occur after exposure in various test methods, e.g. stone chipping, weathering or cross-cut testing. One aim of ISO 21227 is to use optical imaging to reproduce the results of already existing methods for visual assessment. Additionally, optical imaging provides further information which can be used for a more detailed evaluation of coating defects.
This part of ISO 21227 contains a general introduction in optical-imaging methods and definitions. The performance of individual test methods and requirements for precision are described in other parts of the standard.
