Test panels for penetrant inspections

Test panels are used for penetrant-effectiveness testing and result validation, if appropriate. The our test panels made under full use of "Know-How" cultivated in abundant experiences are widely used over the world.

Liquid Penetrant Performance Checks
Test pieces are essential for assessing the performance of liquid penetrant processes and determining that a suitable level of sensitivity is being achieved. We supply a range of commonly used test pieces that can be used to measure and or compare different consumables. Differing types and brands of penetrant will produce different result but the same product can sometimes work differently if contaminated with water or greases etc. This makes such tests essential to reliable and NDT.

1.Type 1 reference test block (JIS Z 2343-3/ISO 3452-3) 

Type 1 Test Panel  ISO 3452-3 JIS Z 2343-3

Reference Block Type 1
Description: ISO 3452-3:2013 describes two types of reference blocks - Type 1 Reference Blocks are used to determine the sensitivity levels of liquid penetrant product families and are supplied in pairs. They are made by cutting a single block in half perpendicular to the direction of the artifical defects.Avialable in versions with 10μm, 20μm, 30μm and 50μm crack depths.
This test panle is known as the "TESCO PANEL", "TESCO-EISHIN PANEL".
For use with systems conforming to:AMS 2647D • ASTM E1208 • ASTM E1209 • ASTM E1210 • ASTM E1219 • ASTM E1220 • ASTM E1417 • ASTM E1418 • ASTM E165 • ASTM F601
• ISO 3452

2.Type 2 reference test block (JIS Z 2343-3/ISO 3452-3) :
Description: ISO 3452-3:2013
describes two types of reference blocks - Type 2 Reference Blocks are for routine assessment of DPI system performance. The block contains 5 artificial star-shaped defects which range from 3.0 to 5.5mm diameters on one side with the 4 adjacent patches
containing different roughnesses of 2.5μm, 5μm, 10μm and 15μm.

3.Type 3 reference test block (JIS Z 2343-3/ISO 3452-3)
The Aluminium Comparator Block is divided into two segments and can be used to
compare different penetrants to one and other or fresh penetrant to penetrant in use. The cracked
Aluminium block is made from 2024 Aluminium with a groove separating the two sides to facilitate side-by-side penetrant comparison. Intended as a single use item.
