INNOVATEST provides top class hardness testing indenters, made out of special alloyed metals, polished to the highest standards and with special treatment penetrator seating. All our hardness testing indenters exceed the ISO / ASTM standards for Rockwell, Brinell, Vickers, and Knoop hardness testing. All indenters are individually packed in protective & anti rust foam cases, labeled with relevant information. All indenters are supplied with ISO/ASTM/NADCAP compliant ISO/IEC 17025 laboratory certificates show individual testing results.
Shaft diameter: ø3mm
Calibration details: This Rockwell Indenter complies with the requirements of DIN EN ISO 6508-2 and ASTM E18 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 scales: A, C, D, N
Calibration temp.: (23 ± 2) °C
Relative humidity: < 70 %rh
Validity: ISO 6508-2 recommends that the Rockwell 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, Board of Accreditation, Netherlands.
Diamond surface appearance: According to the applicable standards.
