ASTM E855-08(2013) PDF

1.1 This standard describes three test methods2 for determining the modulus of elasticity in bending and the bending strength of metallic strips or sheets intended for the use in flat springs:

1.1.1 Test Method A-a cantilever beam,

1.1.2 Test Method B-a three-point loaded beam (that is, a beam resting on two supports and centrally loaded), and

1.1.3 Test Method C-a four-point loaded beam (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 and health practices and determine the applicability of regulatory limitations prior to use.
