Kontrollkörper 1
Reference Block 1
for penetrant testing | acc. to EN ISO 3452-3

Determination of sensitivity levels of fluorescent and colour contrast penetrant systems.

Four brass plates are coated with a 10, 20, 30 or 50 µm thick nickel-chromium-layer. Crack depths are defined by the thickness of the nickel-chromium-layer. Transverse cracks are produced through stretching of the plates in longitudional direction.

The relation crack width : crack depth is approximately 1 : 20 for each crack.

Scope of delivery

  • Reference block
  • Certificate acc. to EN 10204, Type 3.1 B

Application

1.     
 

10 µm, 20 µm and 30 µm plates for deterination of the
sensitivity of  fluorescent penetrant systems

 2.


30 µm and 50 µm plates for determination of  sensitivity of  colour contrast penetrant systems

Reference Block Typ 2
acc. EN ISO 3452-3

Austenitic basic plate, one part of which is chromed, and the other consists of four fields which have been provided with different surface roughnesses for  control of interim cleaning.

At the backside of the chromed part five star-shaped crack centres of different sizes were generated through ball interserting. This side serves for  control of test media.


Application

  • Control of test media and control of interim cleaning
  • NO proof of sensitivity of indications of the respective test medium

Kontrollkörper nach JIS Z 2343
Reference Block acc. to JIS Z 2343

Two brass plates are coated with a 10, 20, 30 or 50 µm thick nickel-chromium-layer (same as reference block no. 1). Crack depths are defined by the nickel-chrome-layer. Transverse cracks are produced through stretching of the plates in longitudional direction.

The relation crack width : crack depth is approximately 1 : 20 for each crack.


Scope of delivery
Reference block incl. certificate

Application

1.     
 

10 µm, 20 µm and 30 µm plates for determination of the
sensitivity of  fluorescent penetrant systems

 2.


30 µm and 50 µm plates for determination of  sensitivity of  colour penetrant systems
 3.

The pair of plates enables the direct
comparison of two different test media

Kontrollkörper NR-5  (PSM-5)
Reference Block NR-5 ( PSM-5)


HELLING  reference block NR-5  corresponds to  reference block PSM-5  acc. to ASTM (TAM Panel 146040).

Rectangly-shaped stainless steel plate with chromium stripes at one side and five crack centres  sorted according to their size. The other side is sand-blasted (medium roughness). 


Application

1.    



 

Side with crack centres:
Monitoring and control of testing process of penetrant testing using manually, semi- or fully automatically operating crack testing equipment.  
(Standard reference block for aerospace industry applications)

 2.

Sand-blasted side: 
Control of excess penetrant removal


Not suitable
for comparative tests with different test systems.

NR-5 | acc. ASME (TAM Panel 146040)
