Minimum dynamic pressure 0,01 MPa (0,1 bar)0,01 MPa (0,1 bar) (0,01 to 0,2) MPa [(0,1 to 2) bar] Type 2a (see Figure 2) Maximum static pressure 0,8 MPa (8 bar) 0,6 MPa (6 bar)
Temperature of the water ≤ 75 °C ≤ 75 °C ≤ 65 °C
a For Type 2, The manufacturer is to declare the minimum operating pressure at which opening, closing and the specified flow rate can be obtained. There is usually no acoustic classification for tapware used in supply systems of Type 2 and no specifications governing the level of noise emissions from these water installations. If supply pressures are such that excessive noise is generated it is recommended that pressure or flow regulators are fitted in the system. Or where practicable, tapware conforming to the appropriate acoustic classification are used. Table 3 — Performance characteristics to be noted if used outside the recommended operating range Issue Supply system type 1 Supply system type 2 Flow performance Taps for Type 2 systems may result in excessive flow velocity Taps for Type 1 system may not provide an acceptable flow rate Noise National regulations shall be observed, the criteria for classification in acoustic groups according to these national (special) regulations being different and more detailed than those given in this standard Taps for type 1 and type 2 systems may result in excessive noise when used above the recommended pressure.
