Editorial Note: For Federal Register citations affecting Sec.
571.3, see the List of CFR Sections Affected in the Finding Aids
section of this volume.
The word any, used in connection with a range of values or set of
items in the requirements, conditions, and procedures of the
standards or regulations in this chapter, means generally the
totality of the items or values, any one of which may be selected
by the Administration for testing, except where clearly specified
otherwise.
Examples: 'The vehicle shall meet the requirements of S4.1 when
tested at any point between 18 and 22 inches above the ground.'
This means that the vehicle must be capable of meeting the
specified requirements at every point between 18 and 22 inches
above the ground. The test in question for a given vehicle may
call for a single test (a single impact, for example), but the
vehicle must meet the requirement at whatever point the
Administration selects, within the specified range.
'Each tire shall be capable of meeting the requirements of this
standard when mounted on any rim specified by the manufacturer as
suitable for use with that tire.' This means that, where the
manufacturer specifies more than one rim as suitable for use with a
tire, the tire must meet the requirements with whatever rim the
Administration selects from the specified group.
'Any one of the items listed below may, at the option of the
manufacturer, be substituted for the hardware specified in S4.1.'
Here the wording clearly indicates that the selection of items is
at the manufacturer's option.
