Test Body JIS Z 2343

Test Body JIS Z 2343 – is used to determine the sensitivity of penetrant systems and for comparing two penetrants, one of which can be taken for standard. It consists of two test panels which are bronze planes 100 х 35 х 2 mm, plated with a NiCr layer. Several crosscut cracks are made in the nickel-chromium plating, the depth of cracks equals the thickness of the NiCr-plating. The bodies are designed in 4 types – with plating thicknesses of 10, 20, 30 and 50 µm. The ratio of crack widths to their depth equals 1:20.
Each test panel is delivered with a certificate according to EN 10204, type 3.1 B, which certifies its conformity to EN ISO 3452-3. The test panels with crack depths of 10, 20 and 30 µm are used for testing of the sensitivity of fluorescent penetrant systems. The sensitivity of contrast penetrant systems is determined by panels with crack depths of 30 and 50 µm.
