This document is to serve as a guide towards location selection criteria for researchers measuring the risk of environmental corrosion. It is not a set of instructions for how to build a standardized test site with well-defined exposure conditions. Rather, the goal of this document is to provide guidance on how to select test locations when pre-installed exposure racks or defined test areas are not established. While this document is part of a group of standards designed to quantify environmental severity for the aerospace and defense industry, this standard is intended to be applicable to all industries.

The scope of this document is to provide a reference for how to select a location for corrosion witness coupons and/or corrosion sensors when established test sites are not available.
