What is the DWTT test?
The Drop Weight Tear Test (DWTT) was developed at the Battelle Institute in the early 1960s. That is why the DWTT test is also colloquially called the Battelle Test. Sometimes it is even referred to as the BDWTT test. The aim of this mechanical material test is to prevent brittle fracture and to ensure crack arrest in pipelines (seamless or welded).
