# Thermal Fatigue at Mixing and Injection Points

Take NoteThere are some specific cases where the [S-RBI assessment approach](/v414/docs/work-process-degradation-management-implementation-steps) in IMS PEI, changes depending on the Degradation Mechanism as well as the [Special Emphasis Component](/v414/docs/guidance-per-special-emphasis-degradation-management). 

Since Mixing and Injection Points are classified as Special Emphasis Components, please find the **guidance** for Thermal Fatigue here: [Thermal Injection and Mixing Points](/v414/docs/thermal-injection-and-mixing-points).
