Background
• At the 6th IG GTR9-PH2 meeting, Flex-GTR Master leg
test data from the round robin tests were requested to
be sent to BASt (A-6-06).
• Japan did not participate in the round robin tests, so we
have no test data which meets the requirements of
A-6-06.
• On the other hand, we have a Flex-GTR Master leg level
impactor in Japan, so we would like to provide its
pendulum test data for IG GTR9-PH2 activity.

Impactor Information
• Flex-GTR Master leg level impactor
 supplied after 12 June, 2012
• The impactor has been used for internal tests at a
Japanese car manufacturer.
 internal pendulum tests as well as car tests

Summary
• Japan investigated pendulum certification test data of a
Flex-GTR Master leg level impactor in Japan.
• All outputs of the Flex-GTR Master leg level impactor fall
within the Flex-GTR Master leg pendulum certification
test corridors, and it was confirmed that the outputs are
stable.
• This result implies that there are no concerns regarding
durability of the Flex-GTR master leg level impactor
under normal use conditions.
