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.

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 2

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

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 the plates in longitudional direction.

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

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

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 (4 x 6 inch) with a chromium stripe 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: Pratt & Whitney Aircraft TAM 146040)
2.	Sand-blasted side: Control of excess penetrant removal

Not suitable for comparative tests with different test systems.

For each testing product family a separate reference block have to ap ply.

Reference block NR-5 fulfils as well as reference block PSM-5 the requirements of

ASTM E1417 (§ 7.8.3.1)
General Electric Specification P3TF2 (§ 5.4.1 and 10.1)
MIL-STD 6866 (§ 5.8.3, 33B-11)
