Low-Energy Charpy V-Notch Specimens SRM must undergo impact testing (fractured) consecutively within the same timeframe (not on separate days) at -40°C ± 1°C. Test results and digital photographs of the fractured samples should not be sent for evaluation. A compliant machine will yield an average value within 1.4 J or 5% of the certified energy value, whichever is higher.
Unit of Issue: Set
SKU: 2093
Unit Description: Each unit includes a set of Charpy V-notch specimens required for one in-house indirect verification (self-verification). The specimens are manufactured from 4340 alloy steel.
Lot Number: LL-198
Validity: Indefinite
Safety Information
These SRMs are test specimens designed for in-house indirect verification of Charpy testing machines in compliance with the current ASTM E23 and ISO 148-2 standards. SRM 2093 is specifically intended for testing at -40°C ± 1°C.
Each unit of SRM 2093 contains between 5 and 7 Charpy specimens. The exact number depends on the statistical variability determined during the certification process for the specific lot, conducted at the Charpy Laboratory, Colorado. The statistical parameter of importance, nss, represents the number of tests required to ensure that the average absorbed energy aligns statistically with the certified absorbed energy.
