Federal Motor Vehicle Safety Standards Call for Changes
Rob Houglum ZIPGlassNetwork.com Wednesday, April 04, 2012
There are recent changes to the Federal Motor Vehicle Safety Requirements that bear on our industry and I presumed I'd give you an alert. These changes are not going to drastically change how we install auto glass, but will accentuate the need for proper installations.
Federal Motor Vehicle Safety Standards 111 Mirrors
This standard has not changed for more than a decade. The main changes that happened ten years back were the "break-away" mirror mounting and the 90 square inch rule for giant over-the-road lorries. The break-away mirrors rule, as you recall, is the rule the mirror mounting must allow the mirror to smash away from the window surface with a force of about 90lbs. The ninety square in. rule applied to passenger cars for a little time, but modified to only include wagons over ten thousand gross car weight ( GVW ). It stated that a mirror with a surface of ninety square inches or less must be convex.
Federal Motor Vehicle Safety Standards 205, 208, 212, 214
These standards have not changed at all and need not waste your time on the details.
Federal Motor Vehicle Safety Standards 216 Roof Crush
This is the standard that's changed the most. In May of 2009 the Nation's Road Traffic and Safety Administration ( NHTSA ) printed its new FMVSS 216a. It was a major change for the ones that tested vehicles so some time was given to design and build the testing apparatus. NHTSA also has a stage in plan for automobile makers to build up their vehicles to meet the new standard. Here are the changes :
There are two fiftieth percentile dummies placed in the 2 front seats to measure the effect of roof crush to the head area.
The test is now performed on both sides of the automobile and not just on the driver side.
A vehicle is present in compliance when the roof does not exceed five inches in aberration and the dummies' heads aren't impacted with more than fifty lbs of force.
There are 2 different methods of testing depending on the car weight :
A. If the car has a GVW of less than six thousand lbs, the roof must resist three times the unloaded automobile weight ( UVW ) ;
B. If the car has a GVW of more than six thousand lbs, but less than 10,000 lbs, the roof must resist 1.5 times the UVW.
The Phase-in was given to makers to reduce the burden of these new standards. To be in compliance the automobile makers have to meet this schedule :
A. Less than 6000 lbs,
I. 25 % compliance by Sep 1, 2012
Ii. Fifty percent compliance by September one, 2013
Iii. Seventy five % compliance by Sep 1, 2014
Iv. One hundred p.c compliance by Sep 1, 2014
B. More than six thousand lbs and less than 10,000 lbs.
I. A hundred percent compliance by September 1, 2016
Federal Motor Vehicle Safety Standards 219 Passenger Compartment Intrusion
This standard no longer exists. It was removed because the current day designs of vehicles are built to reassure passenger compartments are the refuge in a crash. The government felt it didn't need to state the clear and took away the whole standard.
These changes are the most far-reaching change to the FMVSS in years, as it applies to our industry, and the phase-in starts this year. Will this make us change the way we install? No, not really. But it will make us consider carefully about how and what we do and how it'll affect the overall crashworthiness of our customers' vehicles.
