Certification for Failure Detection Systems in Industrial Equipment

Certification for Failure Detection Systems in Industrial Equipment

In todays industrial landscape, the importance of maintaining equipment reliability cannot be overstated. A single failure can lead to significant downtime, production losses, and even safety hazards. To mitigate these risks, many industries rely on advanced failure detection systems (FDS) that use various sensors and algorithms to monitor equipment performance in real-time. However, for an FDS to be effective, it must meet certain standards and certifications to ensure its accuracy, reliability, and compliance with regulatory requirements.

Why Certification Matters

Certification is a crucial aspect of the industrial equipment industry, as it ensures that products and systems meet specific safety, security, and performance standards. For FDS, certification is particularly important because these systems often rely on complex algorithms and sensor data to detect anomalies and predict potential failures. Without proper certification, an FDS may not function correctly or might even introduce false positives or negatives, leading to unnecessary downtime or equipment damage.

Regulatory Framework

Several regulatory bodies worldwide have established standards and guidelines for the development, testing, and deployment of FDS in industrial equipment. Some notable examples include:

  • API 670: The American Petroleum Institute (API) has published a standard (API 670) that outlines requirements for the design, installation, operation, and maintenance of vibration monitoring systems.

  • ISA 95: The International Society of Automation (ISA) has developed a standard (ISA 95) that defines interfaces between business systems and manufacturing control systems, including FDS.

  • IEC 62061: The International Electrotechnical Commission (IEC) has published a standard (IEC 62061) that provides guidelines for the design and integration of functional safety systems in industrial equipment.


  • Certification Process

    To obtain certification for an FDS, manufacturers typically follow these steps:

    1. Design and Development: The manufacturer designs and develops the FDS according to relevant standards and regulatory requirements.
    2. Testing and Validation: The manufacturer conducts extensive testing and validation of the FDS to ensure its accuracy, reliability, and performance.
    3. Certification Application: The manufacturer submits a certification application to an accredited third-party certification body (TPCB), such as UL or ETL.
    4. Audit and Evaluation: The TPCB audits and evaluates the manufacturers design, testing, and validation processes to ensure compliance with relevant standards and regulatory requirements.
    5. Certification Awarded: If the manufacturer meets all requirements, the TPCB awards certification to the FDS.

    Benefits of Certification

    Certification for an FDS offers numerous benefits, including:

  • Improved Reliability: Certified FDS are more likely to detect anomalies and predict potential failures, reducing downtime and production losses.

  • Enhanced Safety: Certified FDS can help prevent accidents by detecting safety-critical issues before they occur.

  • Compliance with Regulations: Certification ensures that the FDS meets relevant standards and regulatory requirements, avoiding non-compliance fines and penalties.

  • Increased Customer Confidence: Certification builds trust with customers, who are more likely to adopt certified products.


  • Frequently Asked Questions (FAQs)

    Q: What are the key differences between API 670 and ISA 95?

    A: While both standards address vibration monitoring systems and manufacturing control systems, respectively, they have distinct focuses. API 670 provides specific requirements for vibration monitoring systems in oil refineries, while ISA 95 defines interfaces between business systems and manufacturing control systems.

    Q: How does IEC 62061 relate to FDS certification?

    A: IEC 62061 is a standard that outlines guidelines for designing and integrating functional safety systems in industrial equipment. For FDS, compliance with this standard ensures that the system meets necessary requirements for functional safety.

    Q: What are some common types of sensors used in FDS?

    A: Some commonly used sensors in FDS include:

  • Vibration sensors

  • Temperature sensors

  • Pressure sensors

  • Acoustic emission sensors


  • Q: Can a manufacturer obtain multiple certifications for their FDS?

    A: Yes, manufacturers can pursue and obtain multiple certifications for their FDS, such as API 670, ISA 95, or IEC 62061. Each certification demonstrates compliance with specific standards and regulatory requirements.

    Q: How does certification affect the cost of an FDS?

    A: While initial costs may increase due to compliance with certification requirements, certified FDS often offer long-term benefits, such as reduced downtime and production losses, which can outweigh these costs.
