TS EN 764-2

TS EN 764-2 is a terminology and notation standard for the basic quantities, symbols and units used with pressure equipment and assemblies. In pressure systems, inconsistent measurement language can create confusion between design, fabrication, inspection and documentation; this standard addresses that by aligning how the relevant quantities are named and expressed.

A common measurement language for pressure equipment

Pressure equipment is a broad technical field covering vessels, piping, safety-related components and combined systems operating under pressure. In this context, quantities such as pressure, temperature, volume, area and mass flow are used together. Clear naming of quantities, unambiguous symbols and consistent use of SI-based units improve traceability from engineering calculations to drawings and reports.

What this standard covers

• Focuses on the basic quantities, symbols and units to be used for pressure equipment and assemblies.
• Provides a common terminology basis for applications addressed by European Directive 97/23/EC.
• Supports consistent use of quantity names and symbols in technical documents, calculations and marking.
• Helps reduce ambiguity in unit selection and symbol usage across engineering work.

In general technical practice, standards like this help different manufacturers and engineering disciplines interpret the same data in the same way. That is especially useful in design verification, equipment marking, quality records and maintenance documentation. The value of TS EN 764-2 lies in providing a shared language for technical communication in pressure equipment.
