Rubert 504 | Precision Reference Specimen | Type D, Ra = 0.15 µm (6 µin), 4 x 1.25 mm random
Rated at Ra = 0.15 µm (6 µin) with a 4 x 1.25 mm random profile, the Rubert 504 is an ISO 5436-1 type D precision reference specimen. It provides a known random-profile surface for checking and calibrating surface measuring instruments. It is offered in two versions: 504E, with a hard nickel-boron top layer, and 504X, without a top layer.
