IEEE C57.12.35-2013 pdf free.IEEE Standard Bar Coding for Distribution Transformers and Step-Voltage Regulators.
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.

bar-code symbol: An array of rectangular bars and spaces that are arranged in a predetermined pattern following specific rules to represent elements of data that are referred to as characters. A bar-code symbol typically contains a leading quiet zone, start character, data character(s) including a check character (if any), stop character, and a trailing quiet zone.
bi- directional bar-code symbol: A bar-code symbol format that permits decoding of the contents whether scanned in one direction or the reverse direction.
character: A letter, digit, or other special form that is used as part of the organization,control, or representation of data. A character is often in the form of a spatial arrangement of adjacent or connected strokes.
character set: Those characters that are available for encoding within the bar code symbol.
check character: A calculated character often included within a bar-code symbol whose value is used for performing a mathematical check of the validity of the decoded data.IEEE C57.12.35 pdf free download.
