This SAE Standard covers the chemical, metallurgical, and mechanical requirements for one piece passenger car and truck ferrous wheel nuts with conical or spherical nut seats for the following sizes: This test is for typical wheel nuts. Special applications (nut material and/or configurations) may require special conditions which must meet load values in 3.4.

This SAE Standard covers the chemical, metallurgical, and mechanical requirements for one piece passenger car and truck ferrous wheel nuts with conical or spherical nut seats for the following sizes: This test is for ordinary wheel nuts. Special applications (nut material and/or configurations) may require special conditions which must meet load values in 3.4.1.

This SAE lab recommended practice may be applied to corrosion test methods such as salt spray, filiform, Corrosion creep back, etc. This procedure is intended to permit corrosion testing to be assessed between Laboratories for correlation purposes.

This document proposes methods for the testing and evaluation of aluminum wheel and wheel trim surface finishes for compatibility with various types of tire, wheel and car wash cleaning materials, and other chemicals that might come into contact with these automotive components. It is recognized that each end user of this methodology might seek answers to questions that are unique to his business or situation. Therefore, the procedure is written in a generic sequence that could be strictly followed, repeated, or modified in order to provide the user with the best results. Example decision tree are provided to help the user select a sequence of exposure steps that would best suit his needs, (reference Figures 1, 2). This procedure should not be utilized if the intent is to evaluate the compatibility of wheel finishes to any flammable products, because those chemistries would require special laboratory safety and handling precautions.
