About This Item
TS 3390 EN 764 is a terminology standard for pressure equipment, focusing on the basic terms and symbols used for pressure, temperature and volume. Standards of this kind help engineers, designers, manufacturers and inspection personnel use the same concepts with the same meaning; in pressure-related calculations and documentation, even a small term mismatch can affect interpretation and communication.
The role of terminology in pressure equipment
Pressure vessels, boilers, piping systems and similar equipment are governed by closely linked variables. Pressure describes the force per unit area acting on a surface, temperature describes the thermal state of a system, and volume describes the space occupied in a closed system. Together, these concepts form the basis for design data, measurement statements and graphical symbols used in technical documentation. Based on the supplied scope, this standard frames how these basic concepts are named and symbolised; it does not evidence any specific test method or numerical limit for pressure equipment.
Why the scope matters in practice
The main value of this standard lies in consistency. It supports a common interpretation of pressure indications, temperature units, volume definitions and their related symbols across documents, organisations and languages. In the EN 764 family, this kind of terminology control is especially useful for safety-related pressure systems, where clear wording supports drawings, specifications and reports without ambiguity.
