Interlaboratory Study on Standard Test Method for Erosion of Solid Materials by a Cavitating Jet


A test method for erosion of solid materials by using a cavitating jet was standardized by ASTM G02 committee in 1995 as ASTM G134. However, an interlaboratory study ILS was not carried out. In order to revise ASTM G134, ILS was carried out in collaboration with four institutions. Five materials, i.e., pure aluminum A1070B, bronze CAC402, popular nickel NW2201, nickel 200 NW2200 and stainless steel SUS316L were tested in the ILS at each institution by using cavitating jet apparatuses, which were compliant with ASTM G134. It was revealed that the variation of the repeatability coefficient was from about 2 % to 7 % and the variation of the reproducibility coefficient was from 6 % to 22 %. Note that the variation of the coefficient in the same institute was about 1 % - 10 %.
