Quote: The rule was not brought about because "it sounded good". It was found in testing by SFI that the belts and/or the thread used deteriorated with age and no longer passed the stress loads required to pass the SFI certification at some point in time.
So unless the seat belt manufacturers can develop a seat belt which will pass the tests for 5 years, and submit them to SFI, you can sign all the petitions you want and it will not change the rule.
Sorry i have a real hard time believing this. My safety harness in the steel mill went thru some crazy testing every year. These were exposed to chemicals, lime, acids, grease, water, heat, and about everything else you can think of. 2 years is crazy dumb.
