Test method for measurement of reaction torque and how such measurements should be evaluated.

This International Standard specifies a test method for evaluation of reaction torque and torque impulse from hand-held pneumatic tools for installing threaded fasteners and gives instructions on how measured data should be evaluated and presented.

This International Standard is directly applicable to assembly torque control tools.

In the case of stall type tools, only the reaction torque can be measured. Impacting, pulsing or ratcheting assembly tools are not covered.
