retention strength test, CG and other requirements for a WC Test Device, platform slip resistai ice<br />
test, hard rail strength test, dynamic inner roll stop test, inner roll stop pinch test, and lift<br />
acceleration filter (CFC) specification. Some of these are areas in which the ATBCB<br />
specifically deferred to <strong>NHTSA</strong>’s expertise and for which VRTC conducted tests and research<br />
The Final Rule has adopted requirements from WC lift standards such as industry standards<br />
(SAE recommended practices and procedures), government procurement requirements (DVA)<br />
and government guidelines (FTA). Some of the new requirements not originally included in tl le<br />
NPRM include: S5.3 - standardized quality, durability and reliability of mechanical, electrical<br />
and hydraulic components/sub-systems, S5.4- environmental corrosion resistance, S6.7 - fatig,ue<br />
endurance and S5.12 - a mechanical counter to support life cycle maintenance.<br />
The Final Rule requires several new hardware improvements to lift operating systems [e.g., foi-<br />
MPVs >4,540 kg mass (10,000 lbs.). GVWR and buses] including; 4-way hazard warning liglits,<br />
upgraded outer barrier, high contrast standee markings, controls lettering size and illuminatior:,<br />
threshold warning device, occupied outer barrier interlock, and occupied inner barrier interloc c<br />
(the 2 interlocks prevent inadvertent flipping of the WC and its occupant). For vans/MPVs
