Following the ASTM/ISO standards for the scratch test
of polymeric materials [37, 38], a series of scratch tests
with the scratch velocity of 100 mm/s were performed for PP using a home-made scratch machine referring to the literature .
There was a significant change in back scratch test
between the pre-test and the post-test on strength assessment day in both CycSG and SSG (p=0.
It is, in fact, well established that the most critical factor controlling the scratch test
is the nature of the stylus tip.
was performed with a scratch-tester (CSM Instruments, Switzerland) which was equipped with Rockwell HRC penetrator with the tip of 120[degrees] cone angle and 100-[micro]m radius.
As the scratch test
could be carried out under small friction force, the deformed depth and width value seem to be almost independent to the surface conditions.
In a scratch test
, surface friction behavior as well as visibility can be characterized by applying controlled scratches to the surface of materials.
A scratch test
could have triggered such a reaction, says study coauthor Alejandro C.
If the clinical profile is suggestive of dermatographism, it is a good idea to do a skin scratch test
to see if the patient develops the characteristic urticarial response to the physical stimulus.

To quantitatively investigate the effect of soft base layer on scratch behavior, a progressive load scratch test
according ISO 19252 was conducted.
The organo-silane improves the interfacial adhesion of the overlying coatings with the substrate, this playing a role in delaying the onset of fractures during the scratch test
