Test panels<br />

Sensitivity of inspection media, quality of intermediate cleaning and control of the whole penetrant<br />

process are determined on reference blocks, i.e. on metal panels with defined roughness and provided<br />

with standardized artificial cracks(defects).<br />

Article No. 127.600.001 - 10 µm<br />

Article No. 127.600.002 - 20 µm<br />

Article No. 127.600.004 - 50 µm<br />

Test body JIS Z 2343<br />

Used to determine the sensitivity of penetrant systems and for comparing<br />

two penetrants, one of which can be taken for standard. Consists of two test<br />

panels which are bronze planes 100х35х2 mm , covered with NiCr-layer. In<br />

NiCr-blanket. Crosscut cracks are made, depth of which fits the width of the<br />

NiCr-blanket. (Designed in 4 types 10, 20, 30 & 50 µm). The quotient of<br />

cracks’ width to their depth equals 1:20. Each test-panel has a certificate<br />

according to EN 10204, type 3.1 B, which verifies its aptitude to EN ISO<br />

3452-3. Test-panels with cracks width of 10 µm, 20 µm, 30 µm used for a<br />

fluorescent sensitivity <strong>testing</strong> penetrant systems. The sensitivity of contrast<br />

penetrant systems is determined by means of panels, depth of cracks in<br />

which - 30 and 50 µm.<br />

Reference block №1 (EN ISO 3452-3)<br />

The type 1 reference block consists of a set of 4 nickel-chrome plated panels with<br />

10, 20, 30 and 50 µm thickness of plating respectively.<br />

The 10, 20 and 30 µm panels are used for determination of the sensitivity of<br />

fluorescent penetrant systems.<br />

The sensitivity of colour contrast penetrant systems is determined by using the 30<br />

and 50 µm panels.<br />

The type 1 panels are rectangular in shape with typical dimensions of 35 x 100 x 2<br />

mm Transverse cracks are made in each panel by stretching the panels in the<br />

longitudinal direction. The width to depth ratio of each crack should be<br />

approximately 1:20.<br />

A declaration stating conformance to EN ISO 3452-3 and in line with EN 10204,<br />

Type 3.1 B shall accompany each test block.<br />

Test body №2 (EN ISO 3452-3)<br />

Article No. 127.400.001<br />

The reference block 2 consists of an austenitic base plate, which is chromiumplated<br />

on one side and provided with 4 different surface roughnesses on the other<br />

side. 5 star-shaped crack patterns of different sizes are generated in the chromiumplated<br />

side by applying a pressure load to the rear side with a ball. The rough areas<br />

are used for control of the intermediate rinse step. The indication on the reference<br />

block gives no suggestion of the indication on the part under test. The user uses the<br />

reference block for the control of inspection material. For checking the rinsability<br />

of penetrants four adjacent areas sized 25 x 35 mm are placed on one half of the<br />

panel with roughness of R a = 2,5 µm, R a = 5 µm, R a = 10 µm and R a = 15 µm. The<br />

defect area is located on the other half of the test surface of the panel. The size of<br />

each defect is determined optically at its maximum diameter using calibrated scales<br />

Test panel ASME V<br />

Article No. 127.550.000<br />

Used for the <strong>testing</strong> of the penetrants indication sensitivity. Due to the<br />

division of the test panel into two parts, it is possible to compare 2 different<br />

penetrants.<br />

Present test panel is an aluminium plate (80х50х10 mm), divided by a notch<br />

(50х2х1,5 mm), into two parts. Because of a special thermal treatment<br />

ASME panel, there is a uniform crack pattern, which is visible on both sides<br />

of the test panel.<br />
