API MPMS CHAPTER 23.2(R2025)

Annotation of standard text API MPMS CHAPTER 23.2(R2025) :

Provide methodologies and processes to monitor liquid tank car movements quantity loss/gain (L/G) ratios, level, and/or quality differences for tank car measurement systems. This document does not establish an industry standard for L/G ratios or level, but under normal operating conditions the standard will assist the user to identify L/G of any tank car system. It will assist to determine: ratio or level deviations, patterns or trends, liquid quality. This document will also make available operational and statistically based tools to: identify when a system exhibits a deviation from its normal operating conditions, guidelines for identifying the causes of the deviation from its normal operating perimeters.
