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 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.4
The results of tests made in accordance with this method should not
be directly compared with those determined in other types of tests
in which the methods of loading and supporting the specimen are
different.
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 2

| d2 = actual diameter of specimen | ||
| Clearance (d1− d2), maximum = 0.02 d + 0.005 in. (0.12 mm) | ||

Note 1: The 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 1.02

| S3 = 1/4 in. (6 mm) for d = 1/16 in. (1.5 mm) to 5/32 in. (4 mm) | ||
| = 1/2 in. (12 mm) for d = 3/16 in. (5 mm) to 3/8 in. (10 mm) |
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.2
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 and health practices and determine the applicability of regulatory limitations prior to use.
