TS EN 135

TS EN 135 is a terminology standard focused on the arrangement of equivalent terms used in the field of respiratory protective devices. Standards of this kind help ensure that different languages and technical traditions refer to the same product or function in a consistent way, supporting clearer communication in manufacturing, testing, procurement and technical documentation.

Why equivalent terminology matters

Respiratory protective devices are equipment intended to protect the wearer from hazardous airborne particles, gases or vapours. In this field, the terms used for masks, filters, hoods and related components can easily overlap in everyday language and technical writing. A list of equivalent terms helps clarify which expressions correspond to the same concept, reducing the risk of misunderstanding across documents and markets.

Technical context of this standard

• The standard addresses terms associated with respiratory protective devices.
• Its main purpose is to group equivalent expressions for the same concept.
• It focuses on terminology alignment rather than product design or performance testing.
• It supports a common language for describing and classifying respiratory protective equipment.

TS EN 135 should not be read as a product performance standard on its own; its role is to organise terminology for this subject area. That makes it useful when preparing specifications, writing catalogues or checking regulatory references, where consistent wording matters. It serves as a foundational reference for understanding and documenting respiratory protective equipment correctly.
