    1、Designation: F 1005 91 (Reapproved 2002)An American National StandardStandard Practice forHVAC Duct Shapes; Identification and Description of DesignConfiguration1This standard is issued under the fixed designation F 1005; the number immediately following the designation indicates the year oforiginal

    2、 adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers the identification of design configu-rations

    3、and descriptive nomenclature for sheetmetal HVACductwork shapes frequently used in shipbuilding. This practicealso covers parametric dimensions of these shapes. (See Table1.)1.2 This practice does not cover the location of seams orjoints within a shape or the method of joining shapes together.1.3 Si

    4、nce this practice is not measurement sensitive, it isapplicable whether inch-pound or SI metric dimensions areused.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate

    5、safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Terminology2.1 Definitions of Terms Specific to This Standard:2.1.1 branchportion of a duct system connection to amain duct.2.1.2 elbowa fitting used to change direction of air flow.2.1.3 flat oval

    10、pe of the duct.2.1.16 vaneinternal part of vaned turns. Used to providemore uniform velocity of air flow. Configuration, number, andlocation of vanes is determined from drawing, NAVSHIPS No.S3801-385260.2The direction of airflow must be marked onvaned turns.2.1.17 vaned turna fitting containing vane

    11、s that is used tochange the direction of air flow.2.2 Variables Specific to This Standard:AAngle.
