Devices to prevent pollution by backflow of potable water - Unrestricted air gap-Family A - Type A

This document specifies the characteristics and the requirements of unrestricted air gap Family A, Type A for nominal flow velocity not exceeding 3 m/s. Air gaps are devices for protection of potable water in water installations from pollution by backflow. This document applies to air gaps in factory-assembled products and to constructed air gaps in situ and specifies requirements and methods to verify and ensure compliance with this document during normal working use. The fluid in the receiving vessel is assumed to have similar properties to the water supply. Where this is not the case, additional care or tests could be required to verify the efficacy of the solution in practical use. The AA device is intended to be used in potable water installations according to EN 806 (series). Sanitary tapware when installed onto a receiving vessel (e.g. washbasin etc.) might have some restriction of its overflow. This will not compromise the water supply as the tapware might have an air gap, as detailed for example in EN 200 (dimension E), that provides an air gap disconnection. If this is the case, then backflow protection will be assumed to be adequate, and no further testing/verification will be needed.

Automatic steam traps - Classification (ISO/DIS 6704:2026)

Establishes a simple classification of the main types according to the mode of actuation of their obturation device and disregarding their details of conception and construction. Three categories of steam traps can be distinguished: mechanical traps, actuated by the level of condensate; thermostatic traps, actuated by the temperature of the condensate; thermodynamic traps, actuated by fluid dynamics.
