BS EN 62741:2015

This standard BS EN 62741:2015 Demonstration of dependability requirements. The dependability case is classified in these ICS categories:

• 29.020 Electrical engineering in general
• 03.120.01 Quality in general
• 21.020 Characteristics and design of machines, apparatus, equipment

This International Standard gives guidance on the content and application of a dependability case and establishes general principles for the preparation of a dependability case.

This standard is written in a basic project context where a customer orders a system that meets dependability requirements from a supplier and then manages the system until its retirement. The methods provided in this standard may be modified and adapted to other situations as needed.

The dependability case is normally produced by the customer and supplier but can also be used and updated by other organizations. For example, certification bodies and regulators may examine the submitted case to support their decisions and users of the system may update/expand the case, particularly where they use the system for a different purpose.
