1.1 This standard describes three test methods2 for determining the modulus of elasticity in bending, the bending proof strength, and the offset yield strength in bending of metallic strips or sheets intended for the use in flat springs:
1.1.1 Test Method A—a cantilever beam test,
1.1.2 Test Method B—a three-point beam test (that is, a beam resting on two supports and centrally loaded), and
1.1.3 Test Method C—a four-point beam test (that is, a beam resting on two supports and loaded at two points equally spaced from each support).
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
