| Abstract: | Due to the scale effects for cavitation inception, it might be diffculty to compare the results tested under differenttesting conditions. Therefore, it is necessary to standardize or to arrange some conditions during tests. It was proved that cavi-tation susceptibility of liquid and turbulence of oncoming flow in testing equipments can play main influence on cavitation in-ception number. Some problems on "zero tensile strength" of liquid and on correction of turbulence as standardized techniquesare discussed specially. |

| Keywords: | cavitation inception zero tensile strength turbulence |
