The nature of modern engineering systems is becoming more complex, involving interconnected elements that fail, potentially causing a considerable effect on safety, reliability, and continuity of operations. IEC 60812 provides a standard approach to performing FMEA and FMECA. The standard assists engineers to identify failure modes systematically, their causes and effects, and the level of risk priority to assist in preventive and corrective measures throughout the product lifecycle.
IEC 60812 Failure Modes and Effects Analysis (FMEA and FMECA)
IEC 60812 Introduction
Scope of IEC 60812
- Gives the methodology of FMEA and FMECA applications.
- Applicable to products, processes, and complex engineering systems.
- Facilitates reliability, risk management, and safety examinations.
- Used in design, during development, manufacturing, and maintenance.
- Helps in determining and prioritising possible failures.
- Improves the quality of its products and operational safety.
IEC 60812 Equipment and Sample Preparation
| Specimen Preparation | Define system elements, components, and functional blocks to be analyzed; gather design, operational, and historical failure data |
| Specimen Detail | Representative system architecture, components, and processes reflecting real operational conditions |
| Specimen Size / Dimensions | Non-dimensional analysis covers the complete system hierarchy from the component level to the overall system level |
Applications of IEC 60812
- Aerospace, automotive, and industrial systems.
- Electrical and electronic equipment risk assessment.
- Manufacturing and production lines process failure analysis.
- Medical and critical infrastructure system safety assessment.
- Lifecycle reliability improvement programs
- Design verification.
IEC 60812 Common Challenges and Troubleshooting
Usually, the problems are the lack of identification of all the failure modes, subjective risk ranking, and the lack of information on the probabilities of failures. Ignoring component-component interactions or having non-uniform measures of evaluation may also diminish the effectiveness of the analysis as well. The mitigation of these issues is with the involvement of a multidisciplinary team, historical reliability data, and standard severity and occurrence rating scales.
IEC 60812 Technique, Process, and Data Collection
The method includes enumerating system functions systematically, finding out potential failure modes of each part or process of a system, and assessing the impact of its failure on the performance of the higher-level system. Such data are severity rating, likelihood of occurrence, ability to detect, and the risk priority numbers or the criticality indices. Such data offer a systematic foundation over which risks are compared, and the mitigation measures are chosen.
IEC 60812 Analysis Results and Interpretation
Findings point to the most important failure modes that may be the most threatening to system reliability or safety. High severity and high occurrence ratings mean that there is a need to design or control process improvements immediately. Less serious failure modes can be checked or prevented by way of preventive maintenance. Engineers use the results to design a system in the best way possible, to make it strong, and to reduce a system failure.
IEC 60812 Problem & Solution
Problem: Unpredictable failures can occur in complex systems because failure modes are not identified, and risks are not prioritized.
Solution: IEC 60812 offers a systematic FMEA/FMECA approach to identify, assess, and reduce the possible failures systematically and enhance the reliability and safety of the system throughout its lifecycle.
Expert
The analysis should be carried out by experienced reliability engineers and cross-functional teams that can analyze the failure modes, the cause of failures, and the impact that the failure has on the system.
Cost
Even though the detailed analysis can consume time and skills of experts, the early detection of the risk of failures will save a lot of lifecycle expenses, product recalls, and operational downtimes.
IEC 60812 Testing Procedure and Requirements
| System Definition | Define system boundaries, functions, and operating conditions |
| Failure Mode Identification | Identify potential ways each component or process can fail |
| Effect Analysis | Determine the impact of each failure mode on system performance and safety |
| Cause Analysis | Identify root causes and contributing factors for each failure mode |
| Risk Evaluation | Assess the severity, occurrence probability, and detectability of failures |
