Flow test for faucet

Faucet flow test Different countries have different standards for faucets, which are based on flow tests. The flow test of the faucet means that detecting the flow characteristics of the faucet at a certain temperature and pressure to judge the flow and sealing, so as to judge the quality of the faucet. Generally speaking, the requirements for test in North America are: The minimum flow rate is 0.14MPa (20PSI). The maximum flow is tested under pressure of 0.41MPa; The maximum flow of sprinkler head is tested at 38C hot water and 0.55MPa pressure. The requirements for test in China and Europe are as follows: Bathtub faucet flow rate is greater than 20 L/min under 0.3MPa pressure; Faucets for washbasin, clean body, shower, kitchen and other purposes should flow less than 9 L/min under 0.1MPa pressure. Too large or too small faucet flow is not conducive to water saving. When the faucet flow is too low, there may be a problem with the faucet valve, or slag clogged. Therefore, through the flow test of the faucet, we can have a further understanding of its velocity, pressure and quality.
