ASTM F2220-11

Standard Specification for Headforms

ABSTRACT
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.
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.

INTRODUCTION
This specification identifies the headforms used for testing protective headgear in individualASTM
International test methods and performance standards (standard specifications). This specification was
closely based on the ISO DIS 6220 that is no longer available (having been replaced by EN 960). It
is not possible forASTM International protective headgear standards to reference EN 960 because this
standard makes no provisions for ASTM International impact headforms.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
