Shaft diameter: ø6.35mm
Calibration details: This Vickers Indenter complies with the requirements of DIN EN ISO 6507-2 and ASTM E92 Class B calibrated to standards by an ISO 17025 RvA accredited laboratory, with calibers traceable to Physikalisch-Technische Bundesanstalt National Metrology Institute, (PTB) Braunschweig, Germany.
RvA, UKAS DaKKS, COFRAC are ILAC signatories.
Calibration temp.: (23 ± 2) °C
Relative humidity: < 70 %rh
Lowest test force: 1 gf
Validity: ISO 6507-2 recommends that the Vickers Diamond Indenter be directly verified after 2 years of use.
Uncertainty: The reported expanded uncertainty is based on the standard uncertainty of the measurement multiplied by a coverage factor k, such that the coverage propability corresponds to approximately 95%. The standard uncertainty is determined in accordance with EA 04/2.
Traceability: The measurements are executed using standards for which the traceability to (inter) national standards has been demonstrated towards the RvA.
Diamond surface appearance: According to the applicable standards.
Tip and edges: According to the applicable standards.
Condition of the surface: According to the applicable standards.
