Commercial impact validity

[MarkSTB]

Hey guys

I have one doubt relative to the commercial impact attenuator. The thing is that we allready have a comercial impact attenuator bought for our car for 2011 season, and we used it without any problems in FSUK2011 and Formula ATA 2012.
But the thing is that I have read this in the following website:

There is no required supplier of the Dow Impaxx® 700 foam. However, Dow Impaxx® 700 pre-cut to the Type 11 shape is available for US$150 each plus shipping from BSCI Energy Impact Systems (contact information below). Pricing and availability are subject to change and are at the sole discretion of BSCI Energy Impact Systems. BSCI Energy Impact Systems is not affiliated with SAE International or the Formula SAE Rules Committee. The Type 11 Impact Attenuator is approved for the 2011 FSAE competition season only and the minimum required design may change in future years. The Type 11 Impact Attenuator is approved for the 2011 FSAE competition season only and the minimum required design may change in future years.

It says that Type 11 Impact could only be used in 2011 season, but we had no problems in Italy 2012. I add the link so everyone can see this.

Could there be any problem by using this impact this season?

From your link:
"The Type 12 standard attenuator approved for use in the 2012 competition season is physically the same as the Type 11."
and
"There is no change from the 2012 (Type 12) Impact attenuator."

The rules around using this model have changed (2012), but the thing itself is the same. I would say you're ok as long as the foam isn't degraded or damaged in any way. If you are really worried about it, send an inquiry to the rules commitee for the competition you plan to attend.
