1SAFETY PRECAUTIONS
Make sure to keep fingers and other body-parts clear from the bending area
when performing a test.
Make sure all actions such as the clamping and bending are carried out
without using any heavy forces
Don’t exceed the max. Panel thickness.
Check the mandrel visually for mechanical damages or marks.
2PRODUCT DESCRIPTION
The TQC Cylindrical Bend Test is a very robust yet elegant testing instrument to indicate the elasticity,
elongation and adhesion of a paint film at bending stress. The TQC Cylindrical Bend Test Imperial is designed to
perform tests according to the latest ASTM standards. D522, assessing the resistance of a coating, paint, varnish
or related products to cracking and/or detachment from a surface when, subjected to bending around a
cylindrical mandrel under standard conditions.

1. Sufficiently open the apparatus
to insert the mandrel with the
correct dia. turning the handle
of the pressure rollers anti
clockwise.
3. Pull the handle, and with a
smooth movement, taking
1 - 2 seconds, make an even
180° bend.
2. Place and secure a test-panel in
the apparatus, positioned
against the mandrel. Fix it
upright into the clamp. The
coated side of the panel should
face outwards once the bend
has been made.
4. Release the test-panel from
the test-apparatus and
examine results immediately.
7MAINTENANCE
Though robust in design, this instrument is precision-machined. Never drop it or knock it over
Always clean the instrument after use.
Clean the instrument using a soft dry cloth. Never clean the instrument by any mechanical means such as a
wire brush or abrasive paper. This may cause, just like the use of aggressive cleaning agents, permanent
damage.
Do not use compressed air to clean the instrument.
