This document specifies the conformance testing and marking requirements for hand torque tools used
for controlled tightening of screws and nuts. It also specifies the minimum requirements for declaration
of conformance for hand torque tools.
This document applies to hand torque tools which are classified as indicating torque tools (Type I) and
setting torque tools (Type II).
NOTE Hand torque tools covered by this document are those identified in ISO 1703:2005 by reference
numbers 6 1 00 11 0, 6 1 00 11 1 and 6 1 00 12 0, 6 1 00 12 1 and 6 1 00 14 0, 6 1 00 15 0. ISO 1703 is currently
under revision. In the next edition, torque tools will be moved to an own clause, and with this change the
reference numbers will also change and additional reference numbers will be added.
This document does not specify requirements of calibration certificates for hand torque tools. These
are described in ISO 6789-2.
