36 CFR Parts 1190 and 1191 ADA and ABA Accessibility Guidelines - Preamble (Discussion of Comments and Changes)

104 Conventions

Section 104.1 notes that all dimensions not stated as a "maximum" or "minimum" are absolute and that all dimensions are "subject to conventional industry tolerances." Conventional industry tolerances recognized by this provision include those for field conditions and those that may be a necessary consequence of a particular manufacturing process. In the final rule, the Board has limited this provision so that it does not apply to requirements where a range is provided since the specified range offers adequate tolerances. Section 104.2 addresses rounding in the case of percentages where fractions result.

Comment. Commenters recommended that a statement be added indicating that the figures in the guidelines are provided for information purposes only, consistent with the ANSI A117.1 standard.

Response. A provision has been added in the final rule which states that the figures contained in this document "are provided for informational purposes only" (104.3). This recognizes that all requirements in the guidelines are contained in text and that the figures are provided to illustrate the text-based specifications. Should a figure be interpreted differently from the text, the text governs.
