The EN 45554 standard deals with the assessment of Reparability, Reusability and Upgradability of Energy-related Products, and aims to extend the life of those kind of products. According to the 2021 report of the French Agency for Ecological Transition (ADEME), 83% of French people are concerned about the environment. This means a growing interest for repair. In addition, consumers want products that are increasingly reparable. Therefore, knowing the reparability score of any type of products has become crucial, but this standard only applies to products that consume energy during use. Hence, there is a need to extend reparability to a wider range of products, including mechanical and mechatronic products. To achieve this main objective, one important step of comparison of existing methods is necessary. This paper aims to compare the EN 45554 standard to the existing methods in the literature for assessing reparability. First, a literature review is conducted to identify existing methods for reparability. Then, a comparison study is performed. Finally, based on this comparison, a set of criteria is obtained as an outcome.
