Hello everyone, I am seeking clarification on the differences between failure mechanisms and failure modes in reference to ISO14224 data collection. Despite reading about it multiple times, I am still unsure. Can someone provide a clear explanation for me? Thank you.
Sir, what is there that you fail to comprehend?
ISO14224 defines failure mode as the observed way in which a failure occurs, while failure mechanism refers to the specific physical, chemical, or other processes that result in the failure.

I am consulting ISO14224 for reliability-centered maintenance data, which I believe will assist reliability engineers in conducting Root Cause Analysis (RCA) more efficiently. This topic has been discussed frequently here, and I know you are an expert in SAP-PM. I have come across articles that link reliability-centered maintenance (RM) data with SAP fields, such as mapping failure modes to damage codes.
Great to hear! You mentioned the "Failure mode -> Damage code" relationship. Can you provide more information on the other mapped fields as well?
Hi there! Great question—understanding the distinction can be tricky. In simple terms, failure mechanisms refer to the underlying processes or reasons that cause a failure, such as fatigue, corrosion, or wear, while failure modes describe the specific ways in which a failure manifests, like cracking, bending, or complete breakdown. Think of mechanisms as the "why" behind the failure and modes as the "what" happens as a result. I hope that clears things up a bit!
Absolutely! In the context of ISO 14224, failure modes refer to how a failure manifests—for instance, a pump might fail due to excessive vibration or seal leakage. On the other hand, failure mechanisms are the underlying processes that cause these failures, like material fatigue or corrosion. Understanding both is crucial for effective data collection and analysis because identifying the mechanism helps you prevent the mode from occurring in the future. Hope that clears things up a bit!

Answer: 1. What is the difference between failure mechanisms and failure modes in ISO14224 data collection? - Failure mechanisms refer to the physical or chemical processes that lead to failure, while failure modes are the observable ways in which a system or component fails.
Answer: - It is crucial to differentiate between failure mechanisms and failure modes as this distinction helps in accurately categorizing and analyzing failure data, leading to more effective maintenance strategies.
Answer: - Sure, for a pump system, cavitation (mechanism) can lead to a failure mode such as erosion or pitting on the pump impeller. Identifying cavitation as the mechanism helps in understanding and addressing the root cause of the failure mode.
