This SAE Aerospace Standard (AS) establishes the requirements for heat cured solid film lubricants. For other general or high temperature applications, refer to AS1701. This document requires qualified products.
This document addresses measurement uncertainty and consumer risk as they relate to AS8879 thread inspection. It describes the rationale, theory and methodology used to generate the technical content of the AS5870. The document describes how to calculate measurement consumer risk. It documents all of the calculation methods which industry employs today to calculate what is commonly called measurement uncertainty (Appendices A, B, C, D, E and F). These, in turn, are used to calculate measurement uncertainty ratios which are required inputs to calculate measurement consumer risk. Users of this document can apply the information described herein for the evaluation of the capability of their measurements based on the measurement consumer risk. It involves the analysis of the measurement (product) distribution and biases of both the product and measurement system distributions. It protects the consumer from the worst case distribution results.
This specification establishes the procedure for installing self-locking, floating, attached retention element (A.R.E.) nut assemblies and defines the necessary hole preparation.
