ASTM B547/B547M-00
(Specification)Standard Specification for Aluminum and Aluminum-Alloy Formed and Arc-Welded Round Tube
Standard Specification for Aluminum and Aluminum-Alloy Formed and Arc-Welded Round Tube
SCOPE
1.1 This specification covers aluminum and aluminum-alloy (Note 1) formed and arc-welded round tube in diameters 9 to 60 in. [230 to 1520 mm], made from formed sheet or plate, butt welded by gas-tungsten or gas-metal arc-welding methods with or without the use of filler metal. Note 1-Throughout this specification use of the term alloy in the general sense includes aluminum as well as aluminum alloy. Note 2-The requirements for the sheet and plate used are the same as in Specifications B209 or B209M.
1.2 Alloy and temper designations are in accordance with ANSI H35.1 [H35.1M]. The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by A9, for example, A91100 for aluminum 1100 in accordance with Practice E527.
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
1.4 The values stated in either inch-pound or SI units are to be regarded separately as standards. The SI units are shown either in brackets or in separate tables. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems will result in nonconformance with the specification.

A
Limits are in percent maximum unless shown as a range or stated otherwise.
B
Analysis shall be made for the elements for which limits are shown in this table.
C
For purposes of determining conformance to these limits, an observed value or a calculated value obtained from analysis shall be rounded to the nearest unit in the
last right-hand place of figures used in expressing the specified limit, in accordance with the rounding method of Practice E 29.
D
Others includes listed elements for which no specific limit is shown as well as unlisted metallic elements. The producer may analyze samples for trace elements not
specified in the specification. However, such analysis is not required and may not cover all metallic Others elements. Should any analysis by the producer or the purchaser
establish that an Others element exceeds the limit of Each or that the aggregate of several Others elements exceeds the limit of Total, the material shall be considered
nonconforming.
E
Other Elements—Total shall be the sum of unspecified metallic elements 0.010 % or more, rounded to the second decimal before determining the sum.
F
The aluminum content shall be calculated by subtracting from 100.00 % the sum of all metallic elements present in amounts of 0.010 % or more each, roundedtothe
second decimal before determining the sum.
G
Composition of cladding alloy as applied during the course of manufacture. Samples from finished tube shall not be required to conform to these limits.
