REFERENCE BLOCK NR-5 (PSM-5)
The HELLING reference block NR-5 corresponds to the reference block PSM-5 according to ASTM (TAM Panel 146040).
It consists of a rectangular stainless steel plate (153 mm x 102 mm). On one half there is a chrome strip; on it five crack centers sorted according to size. The other half is sandblasted (medium roughness).
1. Part with the crack centers:
Monitoring and control of the testing process of penetrant testing on manual, semi-automatic and fully automatic crack detection test facilities.
(Standard reference block for the aerospace industry: Pratt & Whitney Aircraft TAM 146040).
2. Sand-blasted part:
Control of the excess penetrant removal.
NOT suitable for performing comparative tests with different test systems.
For each testing product family in operation a separate reference block must be used.
Just like reference block PSM-5, reference block NR-5 also meets the requirements of
- ASTM E1417 (§ 184.108.40.206)
- General Electric Specification P3TF2 (§5.4.1 and 10.1)
