Rockwell Indenters

Shaft diameter: ø6.35mm

Calibration certificate details:

This Rockwell Cone Indenter exceeds the requirements of DIN EN ISO 6508-2 and ASTM E18 Class B and are calibrated to applicable standards by an ISO 17025 RvA accredited laboratory, with calibers traceable to PTB  (Physikalisch-Technische Bundesanstalt National Metrology Institute, Braunschweig, Germany.)

The RvA (Board of Accreditation) like UKAS, COFRAC, DaKKS are signatories of ILAC MRA.

Applicable scales:

Calibration scales: A, C, D, N

Laboratory conditions:

Calibration temp.: (23 ± 2) °C

Relative humidity: < 70 %rh

 

Lifetime conditions:

ISO 6508-2 recommends that the Rockwell Cone Indenters should be recalibrated after 2 years of use. The standard uncertainty is determined in accordance with EA 04/2. The reported expanded uncertainty is based on the standard uncertainty of the measurement and is multiplied by a coverage factor k, in such a way that the coverage probability corresponds to approximately 95%. The measurements traceability is executed using standards for which the traceability to national and standards has been demonstrated towards the Netherlands RvA.

Diamond surface appearance: Exceeding the applicable standards.

Tip and edges: Exceeding the applicable standards.

Condition of the surface: Exceeding the applicable standards.
