TS EN ISO 16972

TS EN ISO 16972 is a terminology standard for respiratory protective devices that defines terms, sets out units of measurement, and identifies graphical symbols that may appear on the devices themselves or in their instructions. Read with its title and scope, the standard is concerned with a common technical language and user guidance symbols rather than with performance testing of the equipment.

Why terms and symbols are treated together

Respiratory protective devices are used to protect the wearer from inhalation hazards such as particulates, gases, vapours or oxygen-deficient atmospheres, depending on the device type and intended use. In this field, precise vocabulary matters: terms such as mask, facepiece, filter, hood or powered air-supplied system can mean different things in different contexts. By standardising terminology, this document supports consistent understanding across manufacturers, trainers, specifiers and users. Graphical symbols serve a practical role as well, helping to communicate operating, maintenance or installation information visually on the product or in instruction manuals.

What the scope excludes

• Diving apparatus is excluded; EN 250 is identified for terms and definitions related to diving equipment.
• The standard’s core purpose is to define terms and identify graphical symbols that may be required for respiratory protective devices.
• Its focus is on consistent communication and user instruction, not on prescribing product performance tests.

In general technical practice, terminology standards like this one help align product design, procurement documents, training materials and operating instructions. For respiratory protection, that consistency is especially valuable because correct selection, fitting and use all depend on shared understanding of the equipment and its labels. TS EN ISO 16972 provides that common language for the respiratory protection domain.
