Atom The FIA caused some unexpected action yesterday. It pointed out that several teams, particularly Ferrari, Mercedes and Force India, were in some error concerning their overalls and they were going to enforce the regulations as of this race.
It is the first and probably last time anyone outside motorsport paddocks cared about the contents of Appendix III of the FIA Standard 8856-2000. Specifically, the label confirming the suit complies with this high safety standard "must be embroidered onto the outermost layer of the outer garment". Ironically, using a different method to indicate compliance means that the FIA no longer considers those overalls compliant due to not indicating their status correctly.
By not using thread, some were saving a little weight. Ferrari, Mercedes and Force India's drivers all went to scrutineering in Germany with overalls not in compliance with the regulations in this respect. It is unclear how many teams would not have been in compliance had overalls intended for Saturday and Sunday been checked as well (drivers often use a different overall each day for freshness and weight reasons).
It may seem a nit-picky regulation, but it ensures the compliance sign is clear throughout the life of the overall. Thread is harder-wearing than even the best screen-printing, even though in the case of a F1 overall the wear difference is not really tested. The surprise is that it took so long for the overall manufacturers to come into compliance and for the FIA to notice there was a problem. I find it hard to believe that this is the first time all year someone has turned up with a screen-printed compliance logo. Maybe it just proves different scrutineers focus on different potential problems.
