STATE STANDARD OF THE USSR UNION

(Changed edition, Amendment No. 1).

By Decree of the USSR State Committee on Standards dated March 31, 1981 No. 1675, the introduction date was established

from 01.07.81

This standard applies to electrical circuits, as well as design documents containing information about elements, devices and functional groups of electrical circuits, performed manually and automatically in all industries, and establishes types of conventional alphanumeric designations of elements, devices and functional groups, as well as the rules for their construction.

The standard does not apply to railway signaling, centralization and interlocking schemes.

The standard fully complies with ST SEV 2182-80.

GENERAL PROVISIONS

1.1. Conventional alphanumeric designations (hereinafter referred to as designations) are intended:

for unambiguous recording in an abbreviated form of information about elements, devices and functional groups (hereinafter referred to as parts of the object) and documentation for the object;

for references to corresponding parts of an object in text documents;

for application directly to the object, if this is provided for in its design.

1.2. Depending on the purpose and nature of the transmitted information, the following types of designations are established:

highest level - devices (additional designation);

highest level - functional group (additional designation);

constructive location - constructive designation (additional designation);

element - position designation (mandatory designation);

electrical contact (additional designation);

part of the object with which this part of the object is mated, or the location on the document of the image or information about this part of the object (address designation).

Depending on the completeness of the transmitted information, the conventional alphanumeric designation may have a simple or complex structure, i.e. structure in the form of designations of individual types or in the form of a composite designation.

If necessary, it is allowed to use designations and their qualifying symbols, the types of which are not established by this standard. The content and method of recording such designations must be explained in the documentation for the object (for example, on the diagram field).

Definitions of terms used in the standard are given in Reference Appendix 2.

1.3. The use of conventional alphanumeric designations in documents is established by the rules for the execution of the relevant documents (diagrams, drawings, text documents, etc.).

Unified system of design documentation. Alphanumeric designations in electrical circuits

current This standard applies to electrical diagrams, as well as design documents containing information about elements, devices and functional groups of electrical circuits, performed manually and automatically in all industries, and establishes types of conventional alphanumeric designations of elements, devices and functional groups , as well as the rules for their construction. The standard does not apply to railway signaling, centralization and blocking schemes

Probably, in any electrical circuit, in addition to graphic ones, there are always alphanumeric symbols. The document regulating the correct alphanumeric designations of various elements of the electrical circuit is GOST 2.710-81 ESKD (Unified System of Design Documentation) Rules for the execution of circuits.
