Product Code:SAE J2315
Title:Wheel Nut Seat Strength
Issuing Committee:Wheel Standards Committee
Scope: The purose of this test is to evaluate the axial strength of the nut seat of wheels intended for use on passenger cars, light trucks, and multipurpose vehicles. In addition, a minimum contact area is recommended to ensure enough strength for the rotational force in tightening a nut against the nut seat. while this test ensures the minimum strength of the nut seat, the wheel must also have a degree of flexibility. this flexibility, as well as bolt tension, are important to maintain wheel retention.

MIL-PRF-32224, PERFORMANCE SPECIFICATION, SMOKE SENSORS, IONIZATION AND PHOTOELECTRIC, ADVANCED FIRE AND SMOKE SENSOR SYSTEM (AFSSS) (25 OCT 2006)., This specification covers the performance requirements for both ionization and photoelectric smoke sensors (see 6.8.10 and 6.8.12, respectively) and their universal bases and junction boxes, which are components of an overall Advanced Fire and Smoke Sensor System (AFSSS) for use on naval ships. These ionization and photoelectric smoke sensors, universal bases, and junction boxes may be of commercial-off-the-shelf (COTS) design, but must be rugged (see 6.8.15) enough to meet all of the requirements of this performance specification and the rigors of Navy shipboard service. Performance requirements for the other associated AFSSS components (e.g., heat sensors (see 6.8.9), flame detectors (see 6.8.7), Flame Detector Zone Modules (FDZM) (see 6.8.8), Switch Closure Zone Modules (SCZM) (see 6.8.20), isolators (see 6.8.11), and alarm panel (see 6.8.2)) are contained in their respective AFSSS specifications.
