Definitions
Reference value The specified value of an influencing factor to which are referred the characteristics of the equipment
Nominal range The range of values of an influencing quantity (factor) within which, under specified conditions, the equipment meets the specified
requirements
Operative range The range of values of a given energizing quantity for which the equipment, under specified conditions, is able to perform its
intended functions according to the specified requirements
