26、rant product families; Type 2 reference blocks are used for routine assessment of the performance of both fluorescent and colour contrast penetrant testing.The reference blocks are to be used in accordance with part 1 of this International Standard.2 Normative referencesThe following referenced docu

29、set of four nickel-chrome plated panels with 10 m, 20 m, 30 m and 50 m thickness of plating, respectively. The 10 m, 20 m, 30 m and 50 m panels can be used for determination of the sensitivity of fluorescent penetrant systems. The sensitivity of colour contrast penetrant systems is determined using
30、the 30 m and 50 m panels.The Type 2 reference block consists of a single panel 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
31、 reference block design and dimensionsThe Type 1 panels are rectangular in shape with typical dimensions of 35 mm 100 mm 2 mm (see Figure 1). 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 respecti
32、vely. Transverse cracks are made in each panel by stretching the panels in the longitudinal direction. The width to depth ratio of each crack should be approximately 1:20.
