& |/ g4 v' g" NIf the ballast is fixed to a thermo-resisting bush, which is subsequently fixed into a thermoplastic support part of the body. Does the linear regression formula apply for both materials?* E# s7 w; Z$ v# y$ S, z) ~" V
Decision:6 H" u1 @# {& p. }# t: I
Yes, even if the thermo-resisting bush is unaffected, it may conduct the heat to the thermo sensitive part. Therefore both materials must be tested. When the ballast is fixed to a thermoplastic body, the test has to be done.( |2 i/ U/ ^, ]" K1 F
