TEST BODY JIS Z 2343

Description

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 100х35х2 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 according to EN 10204, type 3.1 B, which verifies its conformity to EN ISO 3452-3. The test panels with cracks’ depth of 10, 20, 30 µm are used for testing of fluorescent penetrant systems sensitivity. The sensitivity of visible penetrant systems is determined by panels with crack depth of 30 and 50 µm.
