1、Designation: F 2220 02 (Reapproved 2009)An 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 r
2、evision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis specification identifies the headforms used for testing protective headgear in individual ASTMInternational test method
3、s and performance 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 This specification wasclosely based on the ISO DIS 6220 that is no longer available (having been replaced by EN 960).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 provisi
4、ons for ASTM International 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.1.2 The values stated in SI units are to be
5、 regarded asstandard. No other units of measurement are included in thisstandard.2.

Classification4.1 This specification identifies the requirements for fivetest he
15、adform 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 helmetmeasured at a datum level 12.7 mm above the reference plane.5. Dimensions5.1 D
16、atum 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 headforms shall be symmetrical about the midsagittalplane. Internal geometry may
17、 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 is60.25 mm.6. Impact Headforms6.1 Materials and ManufactureThe impact headform

20、gear. 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, 12.7mm above the reference plane.6.6 Product MarkingAll impact headforms shall
