PROBLEM TO BE SOLVED: To provide an evaluation data forming method capable of forming evaluation data of high reliability for evaluating the lubricating state of the lubrication target part in large-scaled equipment, or the like. SOLUTION: The evaluation data forming method for evaluating the lubricating state of the lubrication target part has a process for measuring the number of particles in lubricating oil by a number-of-particle measuring instrument 2 by a slide abrasion test, not only to calculate a first evaluation parameter (lubricating state evaluation parameter Lp) showing the time change ratio of the number of the particles in a lubricating oil from the measured value, but also to measure a second evaluation parameter ( coefficient of frictionμand/or comparative abrasion quantity Ws) that indicates abrasion and/or friction state and a process for obtaining evaluation data (first evaluation data Q1 and second evaluation data Q2), on the basis of the correlation of the first and second evaluation parameters.
