More and more nanoparticles are used for manufactured products, from applications ranging from surface coatings to an introduction in the entire matrix of a material, due to their unique properties compared with usual materials. Hence, more and more questions appear about the behaviour of these products and associated risks during their lifecycle.

First studies demonstrate the feasibility of studying nanoparticles emission in laboratory, especially with abrasive wear and reproducing daily-life stress [1, 2, 3]. However, nanoparticles also appear to be produced during grinding or drilling operations of no-nanomanufactured products [1]. Both topics (nanomanufactured or not) have to be addressed.

The aim of this study is to contribute to safer products containing nanoparticles in order to protect end-users, workers and the environment. For this, new methods and tools allowing the characterization of the nanoparticle release during the product ageing are developed. Mechanical properties of a set of consumer products (independent whether they are nanomanufactured or not) are analysed before and after their solicitation. The ageing is applied either with an adapted commercial abrasimeter or with a demonstrator developed in the framework of this project. If any nanoparticle release is characterized, a re-engineering work of the product can be operated to reduce the emission, which is quantified by browsing again the process.
