CSA C49.3-10:2018 pdf download.Aluminum 1350 wire, annealed and intermediate tempers, for electrical purposes
1.1 CSA C49.3-10 covers the electrical and mechanical characteristics of aluminum 1350 wire, in annealed and intermediate tempers, for stranding into conductors or for use as solid single conductors.
1.2 In CSA Standards,“shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard;“should" is used to express a recommendation or that which is advised but not required; "may" is used to express an option or that which is permissible within the limits of the standard; and“can”is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

Hard-drawn aluminum wire for overhead line conductors
3 Definitions ;
The following definitions shall apply in this Standard:Lot一all reels or coils of wire of the same diameter that are produced
a) at the same location;
b) under the same manufacturing conditions; and
c) during the same time period.
4.1 General
The wire shall be free from all imperfections not consistent with good manufacturing practice.
4.2 Wire sizes
Wire sizes shall be expressed as the diameter of the wire in millimetres, measured to the nearest 0.01 mm.
4.3 Diameter and permissible variations
4.3.1 The diameter of the wire shall not vary from its nominal diameter by more than the amount specified in Table 1.
4.3.2
The diameter of the wire shall be determined in accordance with the method specified in Clause 5 of
CAN/CSA-C60889.
For the purpose of verifying compliance with this requirement, the diameter shall be determined by
taking two measurements at right angles at the same cross-section.
4.4 Joints
4.4.1 Joints made before final drawing
Joints may be made in rods and wire before final drawing, in accordance with good manufacturing practice.
4.4.2 Joints made during final drawing or in finished wire
Joints may be made during final drawing or in the finished wire by
a) elecric butt welding;
b) electric butt cold-upset welding; or
c) cold pressure welding.
Not more than two such joints shall be present in any reel or coil of the nominal specified weight.CSA C49.3-10 pdf download.
