Description / Abstract:

Clauses 4 to 7 cover performance, acoustical testing, and packaging requirements for personal hearing protection devices (HPDs). Clauses 8 to 12 cover the selection, care, and use of HPDs, which will contribute to an effective hearing loss prevention program.

The following types of HPDs are covered in this Standard:

a) earplugs (including semi-inserts);

b) earmuffs; and

c) helmets, with or without electronic communication capabilities.

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 requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
