The Parties shall keep each other informed about such disputes and, where
appropriate, cooperate in resolving them.
The data importer agrees to notify the data exporter and, where possible, the data subject
promptly (if necessary with the help of the data exporter) if it:
i. receives a legally binding request from a public authority, including judicial
authorities, under the laws of the country of destination for the disclosure of
personal data transferred pursuant to these Clauses; such notification shall include
information about the personal data requested, the requesting authority, the legal
basis for the request and the response provided; or
ii. becomes aware of any direct access by public authorities to personal data
transferred pursuant to these Clauses in accordance with the laws of the country of
destination; such notification shall include all information available to the importer.
The Parties shall keep each other informed about such disputes and, where
appropriate, cooperate in resolving them.

It is better to
fill out the part at slower speeds in-order to let
any compressed air escape, and to get the best
surface finish on the part.3

• Keep reducing the injection velocity until a
fill time of 10-15 seconds is reached
• Calculate the Relative Viscosity for each of
the Injection Speeds using the equation
above (Transfer Pressure * Fill Time)
• Calculate the Relative Shear Rate for each of
the injection speeds using the equation
(1/Fill Time)
• Plot the points on a graph and find the
optimum velocity
• The optimum velocity will be where the
curve starts to level out
In figure 48 above, the optimum velocity is where
the plotted line crosses the black trend line;
therefore the optimum velocity would be about
1.00 in/sec.
