What is BS EN 15096 about?
BS EN 15096 covers devices to prevent pollution by the backflow of potable water. BS EN 15096 specifies the characteristics of hose union anti-vacuum valves of nominal size DN 15 up to and including DN 25 that are suitable for use in drinking water systems at pressures up to and including 1 MPa (10 bar) and temperatures up to and including 65 °C and for 1 h at 90 °C.
HB protects against back siphonage only and is installed in a vertical downward flow position.
HD protects against backflow and is installed in a vertical downward flow position. HB and HD anti-vacuum valves are for installation exclusively at the connecting point between the stop valve and hose in a vertical downward flow position.
