The sensitivity of colour contrast penetrant systems is determined using the 30 m and 50 m panels.The Type 2 reference block consists of a single panel

26、 of which one half has been plated with electroless nickel and a thin layer of chromium and the other half prepared to achieve areas of specific roughness. The plated side exhibits five star-shaped discontinuities.4 Type 1 reference block design and dimensionsThe Type 1 panels are rectangular in sha

Each panel consists of a uniform layer of nickel-chromium plated on to a brass base, the thickness of nickel-chromium being 10 m, 20 m, 30 m and 50 m respectively. Transverse cracks are made in each panel by stretching the panels in the

28、 longitudinal direction. The width to depth ratio of each crack should be approximately 1:20.4DIN EN ISO 3452-3:2014-03EN ISO 3452-3:2013 (E) Dimensions in millimetresKey1 Transverse cracks2 Nickel chromium plating, thickness 10 m, 20 m, 30 m or 50 mFigure 1 Test panel, reference block Type 1 (schem
