Pendulum Impact Machines: Procedures and Specimens
Siewert T, McCowan C
This STP consists primarily of the papers presented at the Second Symposium on Pendulum Impact Machines: Procedures and Specimens, sponsored by ASTM Committee E28 on Mechanical Testing and its Subcommittee E28.07 on Impact Testing in November, 2004. The Symposium was organized to commemorate the development of and rapid advancement of instrumented impact testing about 100 years ago, and to discuss some current issues.
The papers are organized into four sections by topic: Historical Developments in Impact Testing, Impact Test Procedures and Machine Effects, Reference Specimens, and Issues with Instrumented Strikers.
The 2004 symposium was successful in attracting contributions from many countries. Because of its focus on measurement issues, the majority of the authors were from national measurement institutes and standardization societies. Pendulum impact testing is specified in many construction codes and standards.
The papers in this collection contain information regarding
- impact testing
- international intercomparison
- machine verification
- specimen notching and conditioning
- striker radius
- test procedures
- test temperatures
- indirect verification
- instrumented impact
- ASTM E-23
- Charpy V-notch
- uncertainty
- impact certification program
- reference specimens
- Charpy verification specimen
- reference material
- dynamic yield stresses
- dynamic calibration of instrumented strikers
Purchase this STP as a reference for test procedures, understanding the benefits and limitations of Charpy tests, and verification of Charpy strikers.
