scope:

The test setup specified in this guideline is intended to allow performance and capability measurements of hydraulic impulse screwdrivers.

The guideline aims to give users of impulse screwdrivers guidance for measuring and comparing the performance of hydraulic impulse screwdrivers under controlled conditions.

Every possible effort has been made to identify the critical influences on test setups that conform to this guideline. Test results obtained on other test setups may, however, be influenced by differences in the dynamic characteristics, which hinders direct comparison.

his guideline specifies measuring methods for hydraulic impulse screwdrivers to install threaded joints. It gives guidance for a capability test, states the parameters to be tested, and how to evaluate and present the data. The guideline does not describe a method for routine checks during the production process.
