High-Energy Charpy V-Notch Specimens SRM should be impact tested (broken) consecutively within the same time frame (i.e., not on separate days) at 21 °C ± 3 °C. After testing, a completed questionnaire and digital pictures of the broken samples must be emailed for evaluation.
An acceptable machine will produce an average value within 1.4 J or 5% of the certified energy value, whichever is greater.
Unit of Issue: Set
SKU: 2563
Unit Description: Each unit includes Charpy V-notch specimens required for one indirect verification. The specimens are made from 4340 alloy steel.
Safety Information
These SRMs are designed for the indirect verification of Charpy testing machines, compliant with the current ASTM E23 Standard and ISO 148-2 Standard.
- Testing Temperature: SRM 2563 must be tested at 21 °C ± 3 °C.
- Post-Test Services: Includes a post-test evaluation service and proficiency test data.
- Specimen Quantity: Each unit contains 5 to 7 specimens. The exact number depends on statistical variability determined during lot certification at the Charpy Laboratory.
The statistical parameter nSS specifies the number of tests required to ensure the average absorbed energy is statistically comparable to the certified absorbed energy.
