Fixings tested for torque standards July 1st 2007 In order to test fixings are of
the correct quality and
strength, a flatpack furniture
manufacturer is using
electronic torque tools
supplied by Crane
Electronics. The testing
process can be divided into
two elements.The human
component is to establish
how much torque the
consumer is
likely to apply when
assembling the furniture.
The application testing
varies depending on the
wood grade and screw
material. Fastening with
Allen keys is tested with
Crane Electronics' 10Nm
rotary transducer and
TorqueStar Opta
readout.The effect of DIY
power tools, such as
cordless drills, is also tested
with a 50Nm rotary
transducer. In addition,
tightening with a manual
screwdriver is performed
with a DTS ScrewMaster, a
digital screwdriver with
display, covering a torque
range of 0.5 -5Nm.The tests
identify when the screws
and bolts break, any
failures result in the screws
being removed from the
supply chain. More articles from Crane Electronics Ltd: |
