Super-High-Energy Charpy V-Notch Specimens SRM must be impact tested (fractured) consecutively within the same timeframe (not on separate days) at 21°C ± 3°C. Test results and digital photographs of the fractured samples should not be emailed for evaluation. A compliant machine will produce an average value within 1.4 J or 5% of the certified energy value, whichever is greater.
Unit of Issue: Set
Unit Description: Each unit contains a set of Charpy V-notch specimens required for one in-house indirect verification (self-verification). The specimens are manufactured from 9310 alloy steel.
Lot Number: SH-67
SKU: 2099
Validity: Indefinite
Safety Information
These SRMs are designed for in-house indirect verification of Charpy testing machines, following the current ASTM E23 and ISO 148-2 standards. SRM 2099 is intended for testing at 21°C ± 3°C.
Each unit of SRM 2099 includes between 5 and 7 Charpy specimens. The exact number depends on statistical variability determined during the certification process of the specific lot, conducted at the Charpy Laboratory in Boulder, Colorado. The key statistical parameter, nSS, represents the number of tests required to ensure that the average absorbed energy aligns statistically with the certified absorbed energy.
