What are FMVSS Standards?
FMVSS    stands    for    Federal    Motor    Vehicle    Safety    Standards.        They    are standards   set   by   the   National   Highway   Traffic   Safety   Association   relating   to vehicle   safety.      A   number   of   these   standards   set   “minimum   requirements” for   windshield   retention   in   vehicle   accidents.      Because   the   windshield   is   the most   important   safety   restraint   system   in   a   vehicle,   it's   critical   that   the windshield    not    come    out    in    an    accident.    If    that    were    to    occur,    the passenger    compartment    would    be    compromised,    occupants    could    be ejected   and   the   roof   could   collapse.   Any   of   these   scenarios   would   result   in serious   injury   and   possibly   death.      As   a   result,   FMVSS   must   be   adhered   to with   every   windshield   installation.      The   only   way   to   meet   these   standards is    by    strictly    following    the    vehicle    manufacturers    preferred    installation methods.   These   include,   performing   full   cut   out   procedures,   utilizing   OEM glass   where   possible,   properly   applying   the   necessary   primers   and   using only   the   approved   adhesives   that   provide   the   proper   retention   as   well   as safest   drive   away   times.      FMVSS   were   created   and   are   in   place   to   save your   life.   Unfortunately,   it's   sad   to   say,   not   all   auto   glass   companies comply to these standards.
FMVSS   208    is   occupant   crash   protection   which   specifies   equipment   requirements   for   active   and passive   restraints,   including   air   bags.   There   can   be   no   separation   of   load   bearing   safety   assemblies   in a   30   mph   barrier   crash.   This   pertains   to   the   windshield   because   the   passenger   side   air   bag   deploys   off the windshield in order to perform its safety function.
FMVSS   212    measures   the   windshield   retention   in   a   barrier   crash.   Every   make   and   model   vehicle   is accelerated   to   30   mph   and   crashed   head   on   into   a   concrete   barrier.   The   automobile   must   retain   75 percent   of   the   windshield   along   the   pinchweld   perimeter.   Some   vehicle   manufacturers   require   100% retention in this severe crash test.
FMVSS   216    is   the   roof   crush   performance   test.   It   measures   the   structural   strength   required   to   protect occupants   in   the   event   the   vehicle   rolls   over.   One   and   one-half   times   the   unloaded   vehicle   weight   or 6,000   lbs.   (whichever   is   less)   of   force   is   applied   at   an   angle   to   the   roof.   The   roof   structure   can   depress no more than five inches to pass.
FMVSS   219    is   a   windshield   intrusion   test   that   measures   the   windshields   ability   to   keep   a   15   lb.   object traveling   at   30   mph   from   entering   the   vehicle   cabin.   The   glass   and   adhesive   bond   protects   occupants from intrusion of external objects. The windshield can displace no more than 1/4" to pass.
