"Standard Specification for Headforms"
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.
An explicit set of requirements to be satisfied by a material, product, system, or service: Examples of specifications include, but are not limited to, requirements for; physical, mechanical, or chemical properties, and safety, quality, or performance criteria. A specification identifies the test methods for determining whether each of the requirements is satisfied.
All equipment and/or accessories (whether or not detachable) designed and manufactured specifically to protect the head (typically from impact). This includes hard hats that protect from impact and penetration hazards as well as from electrical shock and burn hazards.

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.
