摘要

In preparation for testing, typically the upper portion of the test fixture is connected to a load cell in the crosshead of the testing machine, and the lower portion of the fixture is connected to the base of the machine. Of major concern among users of testing equipment are the interfaces between the test fixture and the testing machine load cell and base. When a new fixture is considered for purchase, the question arises: Will it interface with existing equipment? There is a seemingly bewildering array of connection configurations. One reason is the lack of standardization in the testing industry. Historically, and continuing to the present time, each testing machine and load cell manufacturer has typically selected its own attachment configurations. There are, and have been over the years, a large number of manufacturers that produce these products. Testing machines, in particular, have evolved over decades of progressive design development. Because a given machine can remain in service for 50 years or more, many generations of machines are still in use. Although load cells typically have shorter useful lives, there are more of them to choose from because a given testing machine might be paired with a number of load cells of different styles and load ranges over its lifetime.
