1、Designation: F 2220 02An American National StandardStandard Specification forHeadforms1This standard is issued under the fixed designation F 2220; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number
2、in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis specification identifies the headforms used for testing protective headgear in individual ASTMInternational test methods and performance
3、 standards (standard specifications). This specification wasclosely based on the ISO DIS 6220 that is no longer available (having been replaced by EN 960). Itis not possible forASTM International protective headgear standards to reference EN 960 because thisstandard makes no provisions for ASTM Inte
4、rnational impact headforms.1. Scope1.1 This standard specifies the materials, sizing, and manu-facturing details of test headforms for use in the testing ofprotective headgear. Details of the exterior dimension of theheadforms are included.2. Referenced Documents2.1 ASTM Standards:2B 92/B 92M Specif

Terminology3.1 Definitions:3.1.1 basic plane, nan anatomical plane that includes thesuperior rim of the external auditory meatuses (upper edge ofthe external
6、 openings of the ear) and the inferior margin of theorbit (the lowest point of the floor of the eye socket) (see Figs.1 and 2).3.1.2 coronal plane, nan anatomical plane perpendicularto both the basic and midsagittal planes and passing throughthe superior rims of the right and left external auditorym
7、eatuses. The transverse plane corresponds to the coronalplane (see Figs. 1 and 2).3.1.3 impact headforms, nheadforms used for impacttesting of protective headgear. Impact headforms shall conformto the external dimension defined in this specification. Theseheadforms shall meet the material, dimension
8、s, mass, andcenter of gravity requirements of this specification. Theseheadforms shall include surface markings corresponding to thebasic, coronal, midsagittal, and reference planes.3.1.4 midsagittal plane, nan anatomical plane perpen-dicular to the basic plane and containing the midpoint of theline
9、 connecting the notches of the right and left inferior orbitalridges and the midpoint of the line connecting the superior rimsof the right and left external auditory meatuses (see Figs. 1 and2).1This specification is under the jurisdiction of ASTM Committee F08 on SportsEquipment and Facilities and

Cl
14、assification4.1 This specification identifies the requirements for fivetest headform sizes: A, E, J, M, and O. The size codes used forheadforms relate to the nominal inside circumference ofhelmets (see Table 1). The nominal inside circumferencevalues refer to the internal circumference of the helmet
15、measured at a datum level 12.7 mm above the reference plane.5. Dimensions5.1 Datum LevelsAll datum levels are quoted relative tothe reference plane (“0” level) and are given in mm.5.2 DimensionsThe external dimensions that the head-forms must conform to are identified in Annex A1 and AnnexA2. The he
16、adforms shall be symmetrical about the midsagittalplane. Internal geometry may be defined to satisfy the require-ments of the individual test specifications. The resultingheadform must still comply with the other requirements of thisspecification.5.3 TolerancesThe tolerance on all linear dimensions
17、is60.25 mm.6. Impact Headforms6.1 Materials and ManufactureThe impact headformsshall be made of K1A-F magnesium (nominal composition0.7 % Zr, balance Mg; Specification B 92/B 92M, Grade9980A).6.2 External DimensionsImpact headforms shall complywith the exterior dimensions given in Annex A1. The pola
18、rcoordinates of the horizontal half-sections at each datum levelabove the reference plane are given.6.3 Performance RequirementsThe impact headformsshall not have resonant frequencies below 2000 Hz.6.4 MassThe total mass of the drop assembly (includingthe instrumented headform and supporting assembl
19、y) shall bedescribed in the specific test method for evaluating protectiveheadgear. The mass of the impact headform may be adjusted toaccommodate the specific test method requirements.6.5 Center of GravityThe center of gravity of the impactheadform shall lie at a point on the central vertical axis,
20、12.7mm above the reference plane.6.6 Product MarkingAll impact headforms shall bemarked with:6.6.1 Headform size;6.6.2 Basic plane;6.6.3 Reference plane; and6.6.4 Midsagittal (longitudinal) and coronal (transverse)planes through the vertical axis.7.
