Test body JIS Z 2343 10/20/30/50 µm

The test body 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 100x35x2 mm, plated with NiCr-layer. Several crosscut cracks are made in the nickel-chrome-plating, the depth of cracks fits the width of the NiCr-plating. The bodies are designed in 4 types – with plating width of 10, 20, 30 & 50 µm. The quotient of cracks’ width to their depth equals 1:20. Each test-panel is provided with a certificate. The test panels with cracks’ depth of 10 µm are used for testing of fluorescent penetrant systems sensitivity.
