TS EN 764-2

TS EN 764-2 is the standard for the consistent use of basic quantities, symbols and units in the field of pressure equipment. It helps technical documentation for pressure equipment and assemblies express the same physical quantity with the same symbol and unit, reducing ambiguity in design, inspection, calculation and communication.

A common technical language for pressure equipment

In pressure equipment engineering, quantities and units are more than notation details: they form the shared language used to read drawings, specifications, calculations and records correctly. Because pressure-related work often involves multiple disciplines, consistent symbols and units help avoid misunderstandings between design, manufacturing, inspection and operation. This standard addresses that common language for the pressure equipment sector.

What this document covers in practice

Based on the supplied scope, the standard specifies the basic quantities, symbols and units to be used for pressure equipment and assemblies addressed by European Directive 97/23/EC. Its focus is not on a specific pressure vessel type or a test method, but on harmonised notation. In practice, that makes it useful wherever technical documentation, calculations, drawings, nameplates or engineering communication must refer to the same quantity in a consistent way.

• Supports consistent quantities and symbols in pressure equipment terminology.
• Helps reduce unit-related confusion in technical documents.
• Promotes a shared notation for pressure equipment and assemblies.
• Is linked to applications addressed by European Directive 97/23/EC.
