BS EN 60027-6:2007

What is BS EN 60027-6 – Symbols for control technology about?

BS EN 60027-6 is the sixth part of the BS EN 60027 series that discusses letter symbols to be used in electrical technology.

BS EN 60027-6 is applicable to control technology. BS EN 60027-6 gives names and symbols for quantities, signals and functions, and their units.

Who is BS EN 60027-6 – Symbols for control technology for?

BS EN 60027-6 on letter symbols used in electrical control technology is useful for:

• Electrical engineers
• Maintenance personnel
• Testing and inspection personnel

Why should you use BS EN 60027-6 – Symbols for control technology?

Control technology consists of devices that control, regulate, monitor, collect data, communicate and diagnose. These devices deal with various signals, quantities and functions and their units. This can lead to confusion for users while addressing these signals and quantities.

BS EN 60027-6 presents a coherent body of letter symbols for the most important physical quantities and functions used in control science and technology, particularly for important variable quantities and (without distinction) the signals representing them.

Overall, the guidelines of BS EN 60027-6 help you to standardize symbols and names for the various important quantities and eliminate confusion.

What’s changed since the last update?

BS EN 60027-6:2007 supersedes Clause 11 of HD 60027-2:2003. In comparison with Clause 11 of HD 60027-2:2003, the following has been altered in BS EN 60027-6:2007:

• The number of physical quantities and of their symbols listed in this European standard has been increased significantly. New clauses for general quantities, for general functions, for characteristic quantities of the step response, for mapping functions and their quantities, and for parameters of transfer elements and control loops have been included
• The hitherto existing series of reserve symbols for variable quantities of the control loop has been deleted. Four symbols out of this series have been used as new symbols for main quantities

The presentation of the denotation of some mathematical concepts specific to the field formerly given in 11.4 has been removed to the column “remarks” of the relevant tables
