ISO 148 is the earlier ISO Charpy pendulum impact method for steel using V-notch test pieces. It has been replaced by the current multi-part ISO 148 series, so new work references those. To match this to your program, talk with our team.
What ISO 148 Covered
The original ISO 148 defined the Charpy V-notch test for steel and the measurement of absorbed energy. Its content is carried forward and expanded in the current parts.
Current Replacement
For new work, use ISO 148-1 for the test method and ISO 148-2 for machine verification. Legacy references to ISO 148 map onto these.
Reading the Designation
Cited as ISO 148 with its year. Confirm whether the controlling document expects the current ISO 148-1. To configure impact testing, request a quote.
