Impact Standards: Charpy V-Notch and Izod Impact Specimens These SRMs are test specimens intended primarily for the verification of Charpy V-Notch testing machines and Izod testing machines. The dimensions of these SRMs comply with the current ASTM Standard E23 and the current ISO 148-1 Standard. SRMs 2092, 2096, and 2098 are NIST-Verification Charpy V-notch specimens that have a post-test evaluation service and proficiency test data available with them. SRMs 2092 and 2096 are to be tested at -40° C; SRM 2098 is to be tested at room temperature (21 °C). These SRMs should be tested (broken) at the same time, then returned to NIST Boulder for evaluation. An acceptable machine will produce an average value within 1.4 J or 5% of the certified energy value, whichever is greater. SRM2092、2096和2098是NIST SRMs 2093 and 2097 are Self-Verification Charpy V-notch specimens that do not have any post-test services available with them. These SRMs provide a lower cost option for the Self-Service user. SRMs 2093 and 2097 are to be tested at -40° C; These SRMs are not returned to NIST Boulder for evaluation. SRMs 2112 and 2113 are NIST-Verification Charpy V-notch specimens that are certified for absorbed energy at two test temperatures and are also certified for maximum force. These SRMs provide a means to verify the performance of the energy and force scales of an instrumented Charpy impact machine at room temperature (21 °C). They can also be used to verify just the energy scale of a machine at -40° C, interchangeably with SRMs 2092 and 2096. Theses SRMs should be tested (broken) at the same time, then returned to NIST Boulder for evaluation. An acceptable machine will produce an average value within 1.4 J or 5% of the certified energy value, whichever is greater. Currently formal bounds are not available to verify the performance of the force scale for a Charpy impact test machine. SRM 2115 is a NIST Izod specimen. Each SRM consists of a set of specimens needed to perform one evaluation. This SRM complies with ASTM Standard E23 dimensional requirements for the Izod (Cantilever Beam) impact specimen, Type D, geometry. PLEASE NOTE: The tables are presented to facilitate comparisons among a family of materials to help customers select the best SRM for their needs.
