This specification establishes the performance requirements and associated test methods for qualifying designs of suspension and nonsuspension production forks employed on bicycles that are intended for use in Condition 3 topography. This kind of condition pertains to rough trails, rough unpaved roads, and rough technical areas and unimproved trails, wherein contact with the irregular terrain and momentary loss of tire contact with the ground may occur during usage. The forks shall go through compression load, bending load, impact resistance, and fatigue tests. Models that fail to meet the specified test requirements shall be rejected.
