The light blue
lines are the standard requirement
lines for wet and dry conditions.
If neither one of the testing
results do not reach their respective
lines then it fails the DIN test. |
|
Of these four
brands only Shimano and Yehstar
passed the DIN test. |
|
The performance
of both Shimano and Yehstar were
double the standard. |
|
Yehstar sound
range is much lower than Shimano's
in both conditions.
(*Sound
measurement includes machine operation
noise as well.) |
|
The bottom graph
is the testing result of our new
improved compound, which
performs virtually the same under
both conditions. |
