Given the prevalence of piping standards in industrial design, the similarity between "B1864" and the well-known of standards is a likely source of confusion. The ASME B16 Series is a collection of over 30 different standards that define the dimensions, pressure-temperature ratings, and materials for pipe flanges and fittings.
The standard outlines a mandatory torque test. The screw is clamped in a test fixture, and torque is applied until failure occurs. The breaking torque must meet or exceed the minimum values specified in the standard's data tables for each given screw size.
