RP 3000提供了关于防止铁路罐车装载石油原油溢流的材料特性、运输分类和数量测量的指南。本文件仅适用于出版时根据美国联邦法规（CFR）被归类为危险等级3-易燃液体的石油原油。RP 3000确定了确定运输分类用石油原油取样和测试频率的标准。它讨论了如何建立一个采样和测试程序，并提供了这样一个程序的示例。本文件提供了包装类别（PG）分配指南，包括后跟的潜在影响，以及不同PG原油的混合。本文件提供了初始测试指南，以及PG分配的持续取样和测试指南。 RP 3000为确定铁路罐车运输原油的装载目标量（LTQ）提供了指导。这包括原油温度和密度的确定、基于装载场景的采样点识别，以及测量设备和过程。还提供了关于测量结果和记录保留的文件编制指南。

RP 3000 provides guidance on the material characterization, transport classification, and quantity measurement for overfill prevention of petroleum crude oil for the loading of rail tank cars.This document applies only to petroleum crude oil classified as Hazard Class 3-Flammable Liquid under the U.S. Code of Federal Regulations (CFR) at the time of publication.RP 3000 identifies criteria for determining the frequency of sampling and testing of petroleum crude oil for transport classification. It discusses how to establish a sampling and testing program, and provides an example of such a program.This document provides guidance on Packing Group (PG) assignment, including the potential effect of heel, and mixing of crude oils of differing PGs. The document provides guidance on initial testing and an ongoing sampling and testing for assignment of PG.RP 3000 provides guidance on determining the loading target quantity (LTQ) of crude oil transported by rail tank car. This includes crude oil temperature and density determination, identification of sampling points based on loading scenarios, and measurement equipment and processes.Guidance on the documentation of measurement results and record retention is also provided.
