TS EN 13792

TS EN 13792 is a standard for the colour coding of taps and valves used in laboratories, together with the associated nomenclature. Its purpose is to support quick recognition of which liquid, gas or vacuum service is being controlled at laboratory service points, helping different supplies remain visually distinct in complex laboratory installations.

Colour and naming at laboratory service controls

The subject of the standard is the colour codes and nomenclature applied on or near laboratory service controls. In general technical use, colour coding is a visual identification method that helps operators recognise the service connected to a tap, valve or outlet at a glance. This is especially useful where several gas, liquid and vacuum lines are present in the same facility, because it reduces the risk of confusion between services.

Defined boundaries of application

• The standard addresses colour codes and nomenclature for liquids, gases and vacuum.
• It covers application of these codes and names on or in the vicinity of laboratory service controls.
• It does not apply to medical or healthcare facilities using medical gases from a medical supply system conforming to EN 737.
• That exclusion limits the document away from medical gas distribution contexts.

In practice, standards of this kind support clearer laboratory layout, maintenance and day-to-day operation by making service identification more consistent. The combination of colour coding and nomenclature is not just decorative marking; it is a structured way to describe different services using the same visual language across equipment. TS EN 13792 is valuable because it brings that visual and terminological order to laboratory taps and valves.
