ASTM B228 is the ASTM standard that covers the Standard Specification for Concentric-Lay-Stranded Copper-Clad Steel Conductors. It provides a technical framework for describing and evaluating this conductor type so buyers, engineers, and suppliers can align on product expectations. By defining a clear specification for the stranded construction, the standard helps support consistent procurement, quality control, and performance review for conductor products used in electrical applications.

What is ASTM B228?

ASTM B228 is a product specification focused on concentric-lay-stranded copper-clad steel conductors. In practical terms, it addresses a conductor made from copper-clad steel arranged in a concentric stranded construction, which is commonly selected when a balance of conductivity and strength is needed. The standard is useful as a technical reference for materials, manufacturing consistency, and compliance checks, helping ensure the conductor product is identified and evaluated against a recognized ASTM specification.

Where is ASTM B228 used?

ASTM B228 is commonly used in specifications, purchasing documents, and quality control processes for stranded conductor products made from copper-clad steel. It is relevant wherever concentric-lay-stranded conductors are selected for electrical installations or related applications that call for defined conductor construction. The standard helps manufacturers, distributors, and end users communicate about the conductor type clearly and verify that supplied material matches the intended specification before installation or acceptance.

Why is ASTM B228 important?

ASTM B228 matters because it supports consistency in the description and evaluation of a specialized conductor product. Using a recognized ASTM specification can reduce ambiguity in procurement and help guide testing, inspection, and acceptance decisions. For engineering and quality teams, the standard provides a common reference point when comparing products, documenting compliance, and managing risk associated with conductor selection. ASTM B228 also helps keep product expectations aligned across the supply chain.
