Features and Benefits Provides specific and general design requirements to meet company objectives. Standardizes system configurations, general equipment requirements and subjective design choices. If it is not possible to standardize, ngineering Standards shall provide guidance and insight concerning design decisions. Provides design criteria that, in all cases, meet or exceed all mandatory regulatory or industry design requirements. Provides limited technical or historic background information related to a design requirement or guideline, when appropriate. Includes a sample calculation in an appendix, when appropriate.
