The purpose of these test methods is to provide valid and repeatable test methods for the evaluation of selectorized strength equipment assembled and maintained according to the manufacturer's specifications. Use of these test methods in conjunction with Specification F2216 is intended to maximize the reliability of selectorized strength equipment design and reduce the risk of serious injury resulting from design deficiencies.

1.1 These test methods specify procedures and apparatus used for testing and evaluating selectorized strength equipment for compliance to Specification F2216. Both design and operational parameters will be evaluated. Where possible and applicable, accepted test methods from other recognized bodies will be used and referenced.

1.2 Requirements—Selectorized strength equipment is to be tested for all of the following parameters:

1.2.1 Stability,

1.2.2 Edge and corner sharpness,

1.2.3 Tube ends,

1.2.4 Weight stack travel,

1.2.5 Weight stack selector pin retention,

1.2.6 Function of adjustments and locking mechanisms,

1.2.7 Handgrip design and retention,

1.2.8 Assist mechanisms,

1.2.9 Foot supports,

1.2.10 Rope and belt systems:

1.2.10.1 Static load,

1.2.10.2 End fitting design,

1.2.11 Chain drive design,

1.2.12 Pulley design:

1.2.12.1 Rope pulley design,

1.2.12.2 Belt pulley design,

1.2.13 Entrapment zones,

1.2.14 Pull in points,

1.2.15 Weight stack enclosure design,

1.2.16 Loading and deflection:

1.2.16.1 Intrinsic loading and associated deflection,

1.2.16.2 Extrinsic loading and associated deflection,

1.2.16.3 Endurance loading, and

1.2.17 Documentation and warnings verification.
