Dear colleagues,

there is no main location for the piston used for roof tests (FMVSS 216a) or for door intrusion tests (FMVSS 214). Using LOMA is more for a not movable device (in my head). Can we find and introduce a better solution? (We used PLAT for plate). Piston perhaps describes it better?

Thanks, Gerd

Dear Gerd,

I provide here some image to visualize the test conditions in the § 571.216a procedure:

: Roof_Test_216a_description.png (167.58 KiB) Viewed 20 times

In the database the following Main Locations are available:

SFAD sounds similar, but is intended for a very specific CRS test rig:

May ACTU (Actuator) could be used here?
Otherwise we should go for a new main Location.
I would prefer to have a general code to be able to use it also for other/similar test devices.
As the relevant contact interface is a plate the PLAT is a good option.
The existing IMPA sound like a dynamic test device?

How do you code the TOB part in the ISO Code?

Kind regards,
Dirk
