Test Report No.: 17702074 003
Part I of II
b) projectile mass, dimensions, speed;
c) applicant identification;
d) design, material and dimensions of the test object;
e) clamping or fixing of the test object;
f) direction of shock, point of impact of the projectile;
g) test result.
Test equipment for impact test
The propulsion device consists of a compressed air
vessel with flanged gun barrel (see Figure H.1). The
compressed air may be released by a valve to accelerate
the projectile toward the test object.
The air gun is fed by an air compressor. The speed of the
projectile may be controlled by the pressure of the air.
The projectile speed is measured near the nozzle of the
gun barrel by a suitable speedometer e.g. by proximity
sensor or photocell.
a) spindle unit shall be set in accordance with the
intended use of the machine especially with respect to
belt tension (in accordance with 6.3);
b) when selecting the spindle speed and the tool (saw
blade, grooving tool) for the test, conditions shall be
chosen which create the greatest kinetic energy;
c) before beginning the test the saw spindle shall be run
