UL’s Functional Safety Standards: UL 991 and ANSI/UL 1998


Description

This three-day technical training course will give you an in-depth exposure to UL’s Functional Safety Standards: UL 991 and ANSI/UL 1998. This course teaches how to effectively use the standards in a product’s design phase, which is critical to its certification and acceptance. During the course, the concepts covered by the standards will be applied to a cross-industry technology topic, highlighting the fact that different standards used in different industries use different metrics for assessing / testing functional safety in such applications.  Day one will consist of a general overview of the standards and will cover Failure Mode and Effects Analysis (FMEA) techniques, the environmental stress test program, and other topics of UL 991. Days two and three will focus on the embedded software requirements of ANSI/UL 1998.

The following topics will be covered in the workshop, which are similar to a variety of other standards having functional safety requirements (e.g. UL 60730-1 Annex H, IEC 60335-1, IEC 61508, ISO 13849, etc.): 

  • Overview of functional safety
  • UL 991:
    • Failure Mode and Effects Analysis (FMEA)
    • Environmental stress tests, including EMC immunity
    • Computational investigation and demonstrated method
    • Follow-up program
  • ANSI/UL 1998:
    • Risk analysis and microelectronic hardware considerations
    • Process definition
    • Qualification of development tools and Off-the-Shelf (OTS) software
    • Software design and partitioning
    • Product and user interfaces
    • Software verification, validation and testing
    • Configuration management and maintenance
    • Documentation
  • Review the UL process steps for functional safety certification

Objectives

  • Analyze the relationship of end-product standard requirements to UL 991 and ANSI/UL 1998 requirements
  • Recognize the applicability of UL 991 and ANSI/UL 1998 requirements to the end-product design
  • Apply FMEA techniques to safety-related circuits to identify “critical” components
  • Learn how to evaluate “critical” components through Computational Investigation and Demonstrated Method
  • Walk through an example UL 991 test program
  • Trace risk identification and analysis through programmable component and software design, implementation and validation processes
  • Assess project management practices against ANSI/UL 1998 requirements
  • Develop submittal documentation for ANSI/UL 1998 compliance
  • Learn more about how these requirements may apply to your own particular product(s) during the interactive Q&A throughout the workshop
  • Identify commonalities between UL 991, ANSI/UL 1998, and other international standards

Target Audience

  • Hardware/firmware designers 
  • Embedded software designers and development managers
