Periodically updated on a yearly bases, the rules cover cracks in different components, for different material, in different location. It consider defects interaction in Appendix 5 - Chapter 5-1. In the case of multiple defects, after determining the dimensions for each defect according to the rules in previous chapters, the non-interaction conditions between the elementary defects given shall be checked. If these conditions are not met, the defects shall be grouped according to a dedicated chapter. This review is done on the basis of RSE-M 2015 edition and last modifications of 2016 edition.
