3、against the face of a marinefacility or a ships hull for the purpose of attenuating the forces inherent in arresting the motion ofberthing vessels safely.Most modern fenders fall into three general classifications based on thematerial used to absorb energy:(1)solid rubber fenders in which the materi
4、al absorbs the energy,(2)pneumatic(air-filled)fenders in which air absorbs the energy,and(3)foam-filled fenders in which thefoam core absorbs the energy.1.Scope1.1 This test method covers the recommended proceduresfor quantitative testing,reporting,and verifying the energyabsorption and reaction for
5、ce of marine fenders.Marinefenders are available in a variety of basic types with severalvariations of each type and multiple sizes and stiffnesses foreach variation.Depending on the particular design,marinefenders may also include integral components of steel,composites,plastics,or other materials.
6、All variations shall beperformance tested and reported according to this test method.1.2 There are three performance variables:berthing energy,reaction,and deflection.There are two methods used todevelop rated performance data(RPD)and published perfor-mance curves for the three performance variables
7、.1.3 The primary focus is on fenders used in berthside andship-to-ship applications for marine vessels.This testing pro-tocol does not address small fendering“bumpers”used inpleasure boat marinas,mounted to hulls of work boats,or usedin similar applications;it does not include durability testing.Its
8、primary purpose is to ensure that engineering data reported inmanufacturers catalogues are based upon common testingmethods.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 This standard does not purport to address all of
9、thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accor-da
