Significance and Use | ||||||||||
5.1?This test method is intended solely for the shear testing of rivets and cold-heading wire and rod, and is not generally recommended for the determination of the shear strength of other products. For rivets, this test method is limited to rivets having a shank length equal to or greater than 2d. Note 2:?The results of shear tests of specimens machined from
products other than wire, rod, and rivets may be greatly dependent
upon the orientation of the specimen within the original test
material, and the direction in which the force is applied relative
to the grain flow in the specimen.4 It
is recommended that shear strengths of other products be determined
by Test Method B769 for
products greater than 0.250 in. (6.4 mm) and Test Method
B831 for products less than
0.250 in. (6.4 mm). Shear strengths developed by this test method
have been shown to vary from those developed by other
methods.5.2?The
results of shear tests are dependent upon the relative and absolute
lengths of specimen which are sheared out, and those which are
supported.5.3?The
presence of a lubricant on the surfaces of the specimen and device
may result in shear strengths up to 3 % lower than those determined
in the absence of lubrication.
Note 3:?In order to be able to test rivets having shanks as
short as 2NoteThe tolerance applicable to the
diameter of the specimen being shear tested must be recognized in
drilling the hole in the device. It is recommended that the drilled
hole size be equal to 1.02d plus 0.005 in. (0.12 mm) less the minus
tolerance applicable to the specimen.
5.4?Investigations have determined that the shear strength decreases slightly as the clearance between the specimen diameter and the diameter of the test hole in the device increases, and that the effect of the clearance decreases with increasing specimen diameter. This test method (refer to Fig. 1) permits clearances for production testing which should affect shear strengths by no more than 2 %. For referee testing, the maximum clearance shall be 0.001 in. (0.03 mm).1.1?This test method covers the double shear testing of aluminum and aluminum alloy rivets with round, solid shanks and cold-heading wire and rod.Note 1:?Exceptions to this test method may be necessary in individual specifications or methods for tests for a particular material. 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. |
