1. This guide presents some generally accepted laboratory methodologies that are used for determining the corrosivity of crude oil.

2. This guide does not cover detailed calculations and methods, but rather a range of approaches that have found application in evaluating the corrosivity of crude oil.

3. Only those methodologies that have found wide acceptance in crude oil corrosivity evaluation are considered in this guide.

4. This guide does not address the change in oil/water ratio caused by accumulation of water at low points in a pipeline system.

5. This guide is intended to assist in the selection of methodologies that can be used for determining the corrosivity of crude oil under conditions in which water is present in the liquid state (typically up to 100x00B0;C). These conditions nor......
