WC10 provides specifications and test procedures for rear-facing wheelchair passenger stations (RF-WPS) that are intended for use only in large accessible transit vehicles (LATV). For LATVs that have lower crash rates per mile, as well as lower severity crashes because of their larger mass, providing a passive containment system for wheelchair users is sufficient to provide a reasonable level of transportation safety with a higher degree of personal independence. The level of safety is comparable to unrestrained seated passengers or standing passengers who hold onto stanchions or straps to resist movement during travel.
Part 1 of the standard describes the scope, relating to RF-WPS, while part 2 references other RESNA and federal standards and part 3 provides relevant definitions. Part 4 defines design requirements in terms of the needed geometry and features required for a RF-WPS, which are described in more detail in Annex A. Performance requirements found in part 5 include testing the static strength of excursion barriers with methods found in Annex C, the allowable amount of wheelchair excursion for the wheelchair when tested using procedures found in Annex B, and a required coefficient of friction for the flooring material. Part 6 contains information, labeling, and instruction requirements, while Part 7 contains reporting requirements. Annex D defines specifications for a manual surrogate wheelchair (MSWC) and a scooter surrogate wheelchair (SSWC) that can be used to evaluate the RF-WPS. Annex E contains design guidelines for RF-WPS.
