IEEE C57.12.35-2013

This standard sets forth bar-code label requirements for overhead, pad-mounted, and underground-type distribution transformers and step-voltage regulators. Included herein are requirements for data content, symbology, label layout, print quality, and label life expectancy. This standard assumes the existence of central transformer databases within utility companies so that bar-code labels need only carry basic transformer identification data.

The purpose of this standard is to promote standardization and uniform use of bar-code labels on distribution transformers and step-voltage regulators when specified by the user. In the longer term, it is hoped that the bar codes provided as a result of this standard will serve as an integral part of electrical utility material and information management systems.

Revision Standard - Inactive-Reserved. 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.
