Interesting. I was with Simpson today. Their ‘D’ rings are one piece and can cert that. Trouble is they cannot make my new fire suit until the rule is clarified.
In case you don't have it handy, here's the rule revision:
4. Section 3.D.3 Arm/Leg Restraints: Page: 42
Add what is in bold after the first sentence in the first paragraph; SFI specification 3.3 arm restrains with a manufacture date of 2006 or later are required in all vehicles. IN ADDITION:
ALL ARM RESTRAINT HARWARE MUST BE OF A SINGLE PIECE MANUFACTURE. I.E. NO TWO PIECE OR WELDED “D” RING STYLE ADJUSTERS. ADJUSTABLE TETHERS SHOULD USE A 3-BAR SYSTEM SIMILAR TO THAT USED IN LAP BELT ADJUSTERS. NON-SOWN IN RESTRAINTS SHALL HAVE A TIGHT FIT AROUND THE NARROWEST PART OF THE ARM. ALL ARM RESTRAINTS MUST BE DEMONSTRATED TO BE EFFECTIVE.
Based on my read, unless a D ring is stamped, or cut from a solid piece of metal, it doesn't meet the rule. Is that what Simpson will certify?
I'd love it if that's the case ... and that the SCTA will accept that assertion.
