TS ISO 3529-3

TS ISO 3529-3 is a terminology standard focused on vacuum gauges used in vacuum technology. Rather than prescribing instrument design or test performance, it organises the language used to identify and describe vacuum gauges so that terms are understood consistently across technical documents. In vacuum measurement, gauges are used to indicate and measure pressure in low-pressure systems, where the terminology often needs to distinguish between different measurement principles and device types.

A shared vocabulary for vacuum gauge terminology

The scope of this part is limited to giving definitions related to vacuum gauges. In general technical context, vacuum measurement behaves differently from ordinary pressure measurement at low pressures, so sensor types, measurement ranges and reference concepts must be distinguished carefully. As a vocabulary standard, it supports consistent use of terms such as indication, sensing element, measurement range and related concepts, but it does not by itself specify performance requirements, calibration procedures or acceptance criteria for a particular gauge.

Why the terminology matters in practice

Vacuum gauges are core instruments in laboratory systems, process equipment and industrial vacuum installations. Clear terminology helps prevent confusion between instruments based on different physical principles and supports consistent communication in catalogues, specifications, training material and maintenance documentation. TS ISO 3529-3 serves as the part of the vocabulary system that brings structure to this area of vacuum gauge terminology.
