IEC 60706-2:2006

Overview

IEC 60706-2:2006 is an international standard established by the International Electrotechnical Commission (IEC) that addresses the maintainability of equipment during the design and development phase. It sets forth maintainability requirements and outlines studies necessary to integrate maintainability characteristics early in the lifecycle of products. The standard provides a clear framework for specifying maintainability criteria in requirement documents or contracts to ensure effective maintenance planning and execution.

This standard is essential for engineers, designers, and maintenance planners aiming to optimize equipment lifecycle costs and ensure high availability and reliability through improved maintainability design.

Key Topics

• Scope of Maintainability
  Defines the maintainability requirements relevant to the design and development phase, emphasizing the importance of considering maintainability as part of planning for maintenance activities throughout the equipment lifecycle.

• Maintainability Principles
  Focuses on integrating maintainability objectives into the design process by addressing maintenance tasks, serviceability, ease of inspection and repair, and minimizing downtime.

• Life Cycle Maintenance Activities
  Covers maintainability considerations through various phases including concept and definition, design and development, manufacture and installation, operational use and maintenance, and disposal.

• Specification of Maintainability Requirements
  Guides on establishing quantitative and qualitative maintainability characteristics, constraints, and verification methods to be embedded in project specifications and contracts.

• Maintainability Studies
  Details the analyses performed during design, including maintainability predictions, allocation of maintainability objectives, and use of analytical tools to foresee and enhance maintainability outcomes.

• Design Support
  Includes practical aids such as design criteria, checklists, liaison roles, and design reviews to ensure maintainability is effectively considered and implemented.

Applications

• Product Development
  Integrating maintainability requirements in early design phases to reduce life cycle costs and improve equipment availability, reliability, and serviceability.

• Maintenance Planning
  Facilitating maintenance strategy formulation by defining clear maintainability objectives and constraints, better supporting maintenance management and scheduling.

• Contracting and Procurement
  Providing a basis for specifying maintainability requirements in procurement documents, ensuring suppliers deliver equipment that meets maintainability expectations.

• System Engineering
  Supporting cross-disciplinary collaboration between design engineers, maintenance experts, and operators to optimize maintainability during product development.

• Reliability-Centered Maintenance (RCM)
  Enhancing RCM programs by coupling maintainability analysis with reliability data to create robust maintenance strategies and resource allocation.

Related Standards

• IEC 60034 Series - related to electrical machinery and their maintainability aspects.
• ISO 9001 - quality management systems, which include aspects of maintainability in product design.
• IEC 60300 Series - dependability management including reliability, maintainability, and availability.
• ISO 14224 - collection and exchange of reliability and maintenance data for equipment.
• IEC 62308 - guidelines for maintainability in power systems and equipment.

By following the guidance in IEC 60706-2:2006, organizations can systematically address maintainability from the early stages of design, reducing costly downtime and ensuring smoother maintenance activities over the equipment lifecycle. This standard enables improved maintenance efficiency, reduced life cycle costs, and higher overall equipment effectiveness.
