NASM 1312-13 defines the procedure and apparatus for testing fasteners in double shear in a half-hole fixture. The standard replaced MIL-STD-1312-13A. The test described in this standard requires constant load rate control throughout the entire test. In addition, total failure of the fastener is undesirable, so break detection and stopping machine movement is critical.
