Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers round, zinc-aluminum mischmetal (Zn-5Al-MM) alloy-coated, steel core wire with three classes of this coating used for mechanical reinforcement in the manufacture of aluminum conductors, steel reinforced. The base metal shall be steel produced by the open-hearth, electric furnace, or basic oxygen process. The steel shall conform to the required chemical composition carbon, manganese, phosphorus, sulfur and silicon. The coated steel core wire shall conform to the required tensile and elongation properties. The wire shall be capable of being wrapped in a close helix around a cylindrical mandrel. For the purpose of calculating mass per unit length, cross sections, etc, the density of the material shall be taken. Wire diamter, mass and permissible variations shall be measured.
