The testing standards, ISO/TS 21346 of individualized cellulose nanofibril (iCNF) materials were published in 2021 while their commercialization is progressing. Japanese National Standardization Body had proposed a project of developing the standards to ISO in 2017, and a domestic drafting team has developed the standards based on its own development methodology. In this paper the methodology shared as implicit knowledge by the drafting team members is systematically described as explicit knowledge. It is specifically expressed as a series of logical processes comprising identification of elemental issues to be considered, step-by-step integration of the elemental issues and the eventual target of publishing coherent and harmonized testing standards for iCNF materials. Additionally, the contents of ISO/TS 21346 resulting from the methodology are concisely reviewed with perspectives of further development in the future.
