Bar code label requirements for specific types of distribution transformers and step-voltage regulators are covered in this standard. Data content for temporary and permanent bar code labeling is described as well as bar code label print quality and durability requirements.

This standard sets forth information code requirements for overhead, pad-mounted, and subsurface distribution transformers and step-voltage regulators. Included are requirements for data content, symbology, layout, and life expectancy. This standard assumes the existence of user databases so information codes need only carry basic identification data.
