N/A
The test is carried out with the guard and/or a sample of
the guard material. The guard support shall be equivalent
to the guard mounting on the machine. For testing guard

After the impact damages found on the guard or material
shall be assessed as follows:
a) buckling/bulging (permanent deformation without
crack);
b) incipient crack (visible only on one surface);

d) penetration (projectile penetrating the test object);
e) guard window loosened from its fixing;
f) guard loosened from guard support.
