Description / Abstract:


This Standard specifies requirements for the performance, design, testing, marking, and instructions of personal energy absorbers and lanyards, including lineman’s pole straps and integrally connected lanyards and energy absorbers.


Energy absorbers and lanyards are used as parts of complete fall arrest, travel restraint, fall restrict, or work positioning systems, as applicable. The scope of this Standard does not include information regarding the proper selection of components in order to assure the intended performance of these systems.

The dynamic drop tests described in this Standard are intended to demonstrate that products covered by this Standard have the necessary strength and durability to provide an acceptable level of service. These tests do not imply that all products covered by this Standard can be used for fall arrest.

The distinction between fall arrest, travel restraint, and work positioning applications should be made by the worker and the appropriate equipment should be selected.


This Standard is not intended for lanyards that are used exclusively as anchorage connectors or used for recreational activities such as climbing or mountaineering.


Unless otherwise stated within this Standard, all units have an acceptable tolerance range of ± 2%.

Units of measure

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.


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.
