T102 Equivalent Facilitation.  The requirements in this document do not prevent the use of alternative designs and technologies that result in substantially equivalent or greater accessibility and usability.  The Department of Transportation regulations contain procedures in 49 CFR §37.7 for determining whether alternative designs and technologies provide equivalent facilitation.

T103 Conventions

T103.1 Dimensions.  Dimensions that are not stated as maximum or minimum are absolute.

T103.2 Tolerances.  All dimensions are subject to conventional industry tolerances for manufacturing processes, material properties, and field conditions.

Advisory T103.2 Tolerances.  Tolerances are not intended to be variances that can be used in design.  Information on specific tolerances may be available from industry or trade organizations and published references.

T103.3 Figures.  Figures are provided for informational purposes only, except for Figure T703.

T103.4 Units of Measurement.  Measurements are stated in metric and U.S. customary units.  The values stated in each system (metric or U.S. customary units) may not be exact equivalents, and each system shall be used independently of the other.
