Worldwide, steel producers yearly make millions of impact tests to see whether their steels meet the specific strength requirements for applications such as ship building or pipeline construction.
Mostly Charpy impact tests are applied which consist of breaking a 55 mm bar of steel with a swinging hammer. These Charpy instruments need to be checked at least yearly to assure reliability. The check consists of breaking steel reference samples with known impact resistance.
The new reference material released by the IRMM has certified impact resistance values for tests at 20 °C and at 0 °C because it is easier to cool test samples to 0 °C in an ice water bath than it is to achieve a stable room temperature of 20 °C.
"With this new reference material we now better serve the operators of impact test instruments in industrial settings, where room temperature is not controlled," a JRC scientist said.
JRC-IRMM is the world's second largest producer of steel reference materials with certified Charpy impact resistance. The new material, with the code ERM-FA013bk, has been processed and certified in accordance to ISO Guides 34 and 35.
Details about material processing and certification are described in detail in the certification report, available together with the certificate in our online catalogue.
