  1. PRESENTATION TO CEN/TC 319VENICE - APRIL 13, 2005 Presented by Thomas Van Hardeveld, M.Sc. P. Eng. Convenor, IEC/TC56/WG3 Dependability management Presentation to CEN/TC 319

  2. Objectives • To describe challenges for maintenance • To explain the mandate of IEC/TC56 with respect to dependability, especially as it relates to maintenance • To describe the structure of dependability standards • To propose a basis for liaison and cooperation between IEC/TC56 and CEN/TC 319 Presentation to CEN/TC 319

  3. Challenges for maintenance • Perception of maintenance as secondary to reliability and other factors • Divided organizationally and usually no single point of responsibility • Challenges caused by outsourcing of maintenance activities • Confusion caused by different philosophies and approaches • No accepted framework for maintenance management • Lack of comprehensive international standards • No consistent terminology Presentation to CEN/TC 319

  4. Definition of dependability Linkage to ISO 9000:2000 standards: TC56 is horizontal committee, applicable to all items • Dependability (proposed new definition) • ability of an item to meet its success criteria, under given conditions of use and maintenance • Notes • The success criteria may be attributes or variables, expressed or implied, and may include, availability of the required service, safety, integrity, security, etc. • An example of an implied success criterion is, that the item shall be safe for the user, other interested parties, property and the environment. • Dependability is achieved by due attention to failure prediction, prevention and mitigation Presentation to CEN/TC 319

  5. Aspects of dependability RELIABILITY Incorporated into design and enabled by operations and maintenance AVAILABILITY Enabled by design, operation and maintenance OPERATION MAINTENANCE DESIGN MAINTAINABILITY Enabled by design and implemented during maintenance MAINTENANCE SUPPORT Considered during design and implemented and optimized during maintenance Presentation to CEN/TC 319

  6. Structure of dependability standards Dependability management 60300-1/2 Vocabulary CORE General dependability Life cycle aspects PROCESS Reliability/ availability Maintainability Maintenance and maintenance support Risk management System dependability SUPPORT Presentation to CEN/TC 319

  7. Structure of maintenance-related standards Dependability management 60300-1/2 CORE PROCESS Maintainability 60300-3-10 Maintenance and maintenance support 60300-3-12/14 SUPPORT Maintainability requirements 60706-2 Reliability Centered Maintenance 60300-3-11 Maintainability studies 60706-2 NWI on Spare parts? NWI on Contracting of maintenance? Testability and diagnostic testing 60706-5 Maintainability verification and collection, analysis and presentation of data 60706-3 NWI on Maintenance performance? Presentation to CEN/TC 319

  8. Framework for IEC 60300-3-14 Management responsibility for maintenance and maintenance policy Maintenance resources: people, parts and materials, support resources, information systems, etc. Maintenance processes: management, support planning, preparation and execution Dependable equipment Maintenance assessment and improvement Presentation to CEN/TC 319

  9. Relationship between IEC/TC56 and CEN/TC319 • Following items are for discussion purposes • Work towards harmonized set of maintenance-related standards • Common terminology and framework • Focus for IEC/TC56 more on linkage to other aspects of dependability and higher level aspects of maintenance • Focus for CEN/TC 319 on more specific European concerns Presentation to CEN/TC 319
