This document specifies the procedure for the determination of the certified flow rate (CFR), a performance parameter for centrifuges, at specific fuel oil viscosities using a defined test oil and a defined test procedure. This document is applicable to marine fuel centrifuges. All values reported as CFR capacities are verified measured values on a defined CFR test bench. Separation efficiency is determined by a defined particle counting method. Scaling based on Stoke\u2019s law and disc stack design is excluded from this document.<\/p>\n
