Description of ASTM-F2220 2012ASTM F2220 - 12Standard Specification for HeadformsActive Standard ASTM F2220 | Developed by Subcommittee: F08.53 Book of Standards Volume: 15.07 ASTM F2220Abstract This specification covers the materials, sizing, and manufacturing details of test headforms for use in the testing of protective headgear. This specification identifies the requirements for five test headform size codes: A, E, J, M, and O. All datum levels shall be quoted relative to the reference plane. The headforms shall be symmetrical about the midsagittal plane. Internal geometry may be defined to satisfy the requirements of the individual test specifications. The impact headforms shall be made of K1A-F magnesium, with the prescribed zirconium and magnesium composition, and shall conform to the specified requirements for: external dimensions, performance (resonant frequency), mass, and center of gravity. All impact headforms shall be marked with: headform size, basic plane, reference plane, and midsagittal (longitudinal) and coronal (transverse) planes through the vertical axis. Other headforms shall be made of material of sufficient strength and stiffness to maintain their geometry during testing and shall comply to the external dimension requirements. This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. 1. Scope 1.1 This standard specifies the materials, sizing, and manufacturing details of test headforms for use in the testing of protective headgear. Details of the exterior dimension of the headforms are included. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
