DANSK DSF/PREN IEC 60300-3-4 PDF

This document gives guidance on specifying required dependability requirements and collating these requirements in a specification, together with the means of assuring the achievement of those requirements. The guidance provided includes: • specifying quantitative and qualitative reliability, maintainability, supportability and availability requirements; • advising purchasers on how to ensure that the requirements will be fulfilled by suppliers; • advising suppliers to help them meet the purchaser’s requirements. Other obligations, such as legislation and governmental regulation may also place requirements on items and these should be applied in addition to any requirements derived in accordance with this standard. Whilst mainly addressing system and equipment level dependability, many of the techniques described in the different parts of IEC 60300 can also be applied to products or at the component level. The term item is used throughout this standard.
