HM 92: model sampling plans for crude oil and liquid hydrocarbon products

This document provides model sampling plans for the manual sampling of liquid crude oil and petroleum products relating to shore tank, road tanker, railcar, drum container sampling, and vessel loading or discharge operations.

Sampling of bunker deliveries to ships is not included as this activity is considered to be adequately covered by existing international standards and local port requirements. These model plans complement existing sampling standards by providing guidance on the type, location and volume of sample which should be drawn in order to provide sufficient sample for retention and also to enable a typical series of laboratory tests to be performed for the determination of product quality. For loading and discharge operations, the plans again provide recommendations regarding sufficient samples for retention and also for analysis and quality assurance relating to custody transfer.
