I am unclear if HANS devices need to be recertified every five years or not?
Here is what I found in the GCR (page 91)
"The use
of a head and neck restraint system that has been certified in
accordance with SFI 38.1, FIA 8858-2002 or 8858-2010 is
required; an SFI 38.1 or FIA 8858-2002 or 8858-2010 label
must be properly affixed to the device."
As long as it has an SFI sticker are we good regardless of the date? That doesn't seem quite right but I can't find anything that says otherwise.
