Industrial protective headwear — Performance, selection, care, and use
This Standard applies to protective headwear for industrial, construction, mining, utility, and forestry
workers. It defines the areas of the head that are to be protected and includes basic performance
requirements for dielectric strength, impact attenuation, penetration resistance, passive retention
(stability), and shell flammability and liner ignition resistance.
This Standard includes requirements for and provides guidance on the selection, care, and use of
The tests specified in this Standard set minimum performance requirements for protective headwear
but do not cover other design factors such as comfort, service life, or appearance.
Note: Compliance with the requirements of this Standard does not imply equality of performance among different
types of protective headwear, nor should it be interpreted to mean that a headwear product is capable of affording
greater protection than is specified in this Standard.
This Standard does not apply to “bump caps”, firefighting helmets, rescue helmets, crash helmets,
sports and recreation helmets, or riot control helmets.
In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to
satisfy in order to comply with the standard; “should” is used to express a recommendation or that
which is advised but not required; and “may” is used to express an option or that which is permissible
within the limits of the standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a
note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as
