ASTM F2918-11(2015)

Standard Test Method for Weighing a Bicycle

SIGNIFICANCE AND USE
5.1 The minimum and as-sold weight of a bicycle are properties used by consumers to evaluate bicycles. The weight may also be used for specifications, manufacturing standards, and quality control.
SCOPE
1.1 This test method covers requirements for weighing and marketing bicycles, including all adult, and childrens bicycles.  
1.2 This standard may contain test methods that do not entirely simulate real life situations. The test methods are designed to give reproducible results in a laboratory and, thereby, a means for product comparison.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
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.
