Standard Test Methods for Evaluating Design and Performance Characteristics of Elliptical Trainers

SIGNIFICANCE AND USE
The purpose of these test methods is to provide reliable and repeatable test methods for the evaluation of elliptical trainers assembled and maintained according to the manufacturer’s specifications. Use of these test methods, in conjunction with Specification , is intended to ensure appropriate performance and reliability of an elliptical trainer and reduce the risk of serious injury from design deficiencies.
SCOPE
1.1 These test methods specify procedures and equipment used for testing and evaluating elliptical trainers for compliance to Specification . Both design and operational parameters will be evaluated. Where possible and applicable, accepted test methods from other recognized bodies will be used and referenced. In case of a conflict between this document and Specification , Specification  takes precedence.
1.2 Requirements—An elliptical trainer is to be tested for all of the following parameters:
1.2.1 Endurance,
1.2.2 Static loading,
1.2.2.1 Handlebars
1.2.2.2 Foot supports
1.2.3 Adjustable guide systems,
1.2.4 Control panel,
1.2.5 Warnings, and
1.2.6 Documentation.
1.3 The values stated in SI units are to be regarded as the standard. The values in parenthesis are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Standard Test Methods for
Evaluating Design and Performance Characteristics of
Elliptical Trainers
This standard is issued under the fixed designation F2811; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
The goal of these test methods is to provide reliable and repeatable methods for the evaluation of
elliptical trainers. The equipment user must recognize, however, that a standard alone will not
necessarily prevent injuries. Like other physical activities, exercise involving fitness equipment
involvestheriskofinjury,particularlyiftheequipmentisusedimproperlyornotproperlymaintained.
In addition, users with physical limitations should seek medical advice or instruction from the fitness
facility, or both, prior to using this equipment. Certain physical conditions or limitations may preclude
some persons from using this equipment properly and without increasing the risk of serious injury.
