1 Presentation to CEN/TC 3191 PRESENTATION TO CEN/TC 319 VENICE - APRIL 13, 2005 Presented by Thomas Van Hardeveld, M.Sc. P. Eng. Convenor, IEC/TC56/WG3 Dependability management

2 Presentation to CEN/TC 3192 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

3 Presentation to CEN/TC 3193 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

4 Presentation to CEN/TC 3194 Definition of dependability 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 Linkage to ISO 9000:2000 standards: TC56 is horizontal committee, applicable to all items

5 Presentation to CEN/TC 3195 Aspects of dependability RELIABILITY Incorporated into design and enabled by operations and maintenance AVAILABILITY Enabled by design, operation and maintenance MAINTAINABILITY Enabled by design and implemented during maintenance DESIGN MAINTENANCE OPERATION MAINTENANCE SUPPORT Considered during design and implemented and optimized during maintenance

6 Presentation to CEN/TC 3196 Structure of dependability standards Dependability management /2 General dependability Reliability/ availability Maintenance and maintenance support Risk management System dependability Vocabulary Maintainability CORE PROCESS SUPPORT Life cycle aspects

7 Presentation to CEN/TC 3197 Structure of maintenance-related standards Dependability management /2 Maintainability Maintainability requirements Maintainability studies Testability and diagnostic testing Maintainability verification and collection, analysis and presentation of data Maintenance and maintenance support /14 Reliability Centered Maintenance NWI on Spare parts? NWI on Contracting of maintenance? NWI on Maintenance performance? SUPPORT CORE PROCESS

8 Presentation to CEN/TC 3198 Framework for IEC 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 Maintenance assessment and improvement Dependable equipment

9 Presentation to CEN/TC 3199 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
