Description / Abstract: This Standard covers perforated tape used for telegraph message (including data) communications, including dimensions of blank (unperforated) tape; dimensions of code and feed holes; and numbering of the transverse positions for the code holes. 2.

Purpose. The purpose of this Standard is to formalize existing standards for 5-level perforated tape used in communications; to include standards for 6-level, 7-level, and 8-level tape which will be compatible with these 5-level standards, in order to prevent confusion and minimize possible obsolescence of existing communications apparatus; and to serve as a basis for an American Standard covering perforated tape for communications use.
