    1. Scope

    empers shown in , and in those standard sizes shown in , as well as in other nonstandard sizes as agreed upon between the purchaser and supplier. Such pipe and tube is intended for use in structural applications such as highway and bridge rails, chain-link fence posts, handrails, sign structures, awning supports, lighting brackets, etc. Structural pipe and tube is not intended for fluid-carrying applications involving pressure.

    Note 1

    For drawn seamless tube used in pressure applications see Specifications B 210 and B 210M, for seamless pipe and seamless extruded tube used in pressure applications see Specifications B 241/B 241M, and for drawn tube and pipe for general purpose applications see Specification B 483/B 483M.

    1.2 Alloy and temper designations are in accordance with ANSI H35.1. The equivalent Unified Numbering System alloy designations are those of preceded by A9, for example, A96061 for alloy 6061 in accordance with Practice E 527.

    1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see .

    1.4 UnitsThe values stated in either inch-pound units or SI units are to be regarded separately as standard. SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the specification.

    1.4.1 While this standard is a combined SI and inch-pound standard, standard pipe sizes are not applicable to SI units, therefore non-rationalized SI units (soft conversions) are shown for reader convenience. Rationalized [hard converted] SI units are shown in brackets while non-rationalized (soft converted) SI units are shown in parentheses.

    This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
