Method for determining the acid value of heat transfer oil
Thread Content
There are two methods for determining the acid value of heat transfer oils: ASTM D974 and ASTM D664. Are the acid value values obtained using these two methods identical?

Since a standard method already exists, by examining its details carefully, one can understand the connections and differences between these two methods. Let’s first look at the differences between these two methods, and then discuss it, okay? If you can’t understand the difference between these two methods, go to http://bbs.hcbbs.com/thread-1226260-1-1.html to ask for help.
I don’t want to discuss any issues. In fact, I have no understanding at all of these two analysis methods; I’m not an analyst either. I merely provided a sample of the heat transfer oil to the manufacturer for analysis, but the results obtained were different from the values listed in the MSDS provided by the manufacturer. I checked to see that these two methods were used for the analysis, and I also consulted relevant materials, but I couldn’t understand them. If there are professionals in analysis who can understand this, please let me know; if not, it’s fine.
