PROBLEM TO BE SOLVED: To provide simulated powder for evaluating a scattered state of powder, a method for producing the simulated powder, a method for evaluating a scattered state of powder using the simulated powder, and a powder handling facility which evaluates a scattered state of powder by the evaluation method.;SOLUTION: There are provided: 1) simulated powder which consists of composite particles in which one or more compound selected from the group consisting of ATP and a derivative thereof are attached to core particles containing lactose; 2) a method for producing simulated powder in which base particles which consists of core particles containing lactose are allowed to collide child particles which consist of one or more compounds selected from the group consisting of ATP and a derivative thereof in high-speed air flow to obtain composite particles in which the surface of the base particles is coated with child particles; and 3) a method for evaluating a scattered state of powder which has: a step of scattering the simulated powder in the space of an evaluation target; a step of recovering the simulated powder scattered to prescribed positions in the space; and a step of analyzing the recovered simulated powder quantitatively or qualitatively.;COPYRIGHT: (C)2015,JPO&INPIT
