Sample evaluation methods
Visual
Color change
Gray scale for assessing color change - color fastness tests
Visual assessment of changes such as yellowing, fading, chalking, discoloration, turbidity
Change of surface
Types of defects:
Shape, size: change in dimensions, deformations (strains), waviness
Surface properties: softening, hardening
Appearance: wrinkling, cracking, fracture, blistering, peeling, discoloration, yellowing, delamination, brittleness
Other properties: loosening, rattling of installed parts
Instrumental
Color change
Instrumental assessment of color change and its expression in gray scale degrees - color fastness tests
Surface change
Gloss change
Determination of gloss values at angles of 20°, 60° and 85°
Change in coating adhesion
Cross-cut examination
Change in durability
Determination of mechanical properties under static tension
Change of hardness
Determination of hardness by pressing method using a hardness tester (Shore hardness)
Changing dimensions
Measurements on a coordinate measuring machine
