Rockwell Penetratori

Diametro attacco: ø3mm

Calibration details:Questo penetratore Rockwell è conforme ai requisiti della normativa DIN EN ISO 6508-2 e ASTM E18 Classe B, calibrato secondo gli standard da un laboratorio accreditato ISO 17025 RvA, con equipaggiamento riconducibile al Physikalisch-Technische Bundesanstalt National Metrology Institute, (PTB) Braunschweig, Germania. RvA, UKAS DaKKS, COFRAC sono firmatari ILAC.

Scale di calibrazione: A, C, D, N

Temperatura di calibrazione: (23 ± 2) °C

Umidità relativa: < 70 %rh

Validità: ISO 6508-2 recommends that the Rockwell Indenter be directly verified after 2 years of use.

Incertezza: 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.

Tracciabilità: The measurements are executed using standards for which the traceability to (inter) national standards has been demonstrated towards the RvA, Board of Accreditation, Netherlands.

Apparenza della superficie in diamante: According to the applicable standards.
