Wilson-Härteprüfblöcke sind der Branchenstandard und bestehen aus hochwertigsten Materialien, um einheitliche und reproduzierbare Prüfergebnisse zu gewährleisten. Wir bieten eine umfassende Palette an Skalen und Blöcken, um die mit Rockwell-, Brinell-, Knoop- und Vickers-Härteprüfungen verbundenen Anforderungen abzudecken. Alle Wilson-Prüfblöcke werden im Wilson-Härte-Kalibrierungslabor in Norwood, MA, kalibriert. Das Wilson-Labor ist von A2LA gemäß ISO/IEC 17025 zertifiziert, und die beim Kalibrierungsprozess verwendeten Prüfgeräte unterliegen einem strengen Überwachungsprozess, bei dem rückführbare NIST-Geräte verwendet werden.
Für die ultimative Präzision und Leistung bei der Überprüfung der Prüfgeräte sind Kalibrierungs-Sets für die meisten Rockwell-Skalen verfügbar.
- Wir arbeiten bei der Festlegung der chemischen Zusammensetzung direkt mit den Stahl- und Messingwerken zusammen.
- Unsere Bearbeitungsvorgänge (Schleifen, Läppen, Polieren) werden alle intern am Ort der Kalibrierung durchgeführt.
- 100%-ige Inspektion, um zu gewährleisten, dass jeder einzelne Prüfblock den physikalischen Anforderungen von ASTM entspricht (Dicke, Ebenheit, Parallelität, Oberflächenrauigkeit)
| Abmessungen des Blocks: | Ø 60 mm x 9 mm (Ø 2,4" x 0,35") |
| Gewicht des Blocks: | ±0,3 kg (0,66 lbs) |
| Zertifizierung: | Nach ISO 6508-3 und ASTM E18 |
| Das Buehler-Wilson Härte-Kalibrationslabor ist nach ISO/IEC 17025 von A2LA akkreditiert. | |
