This part of IEC 60300 gives guidance on specifying the required dependability characteristics
in specifications,together with specifications of procedures and criteria for verification and
vaIidation.
The guidance provided includes the following:
一advice on specifying quantitative and qualitative reliability,maintainability,availability and
maintenance support requirements;
——advice to purchasers of a system on how to ensure that the specified requirements will be
fulfilled by suppliers;
一advice to suppliers to help them to meet purchaser requirements.
Other documents,such as legislation and governmental regulation may also place
requirements on systems and these should be applied in addition to any specifications
derived in accordance with this standard.
NOTE 1 Whilst mainly addressing system and equipment level reliability.many of the techniques described in the
different parts of IEC 60300 may also be applied to products,items or at the component level.The term system is
used throughout this standard.
NOTE 2 This standard does not give guidance on the management of dependability programmes or on the various
activities necessary to fulfil stated availability,reliability,maintainability and maintenance support requirements.
For this general guidance,see other standards.
NOTE 3 Safety and environment specifications are not directly considered in this guide.However,much of the
guidance in this standard could also be applied to safety or environmental specification
NOTE 4 Specifications for the dependability of a service are not considered in this guide.This includes the
provision of a service such as those provided through Public—Private PartnershiP procurements.
