(Practice)Standard Practice for Automatic Sampling of Petroleum and Petroleum Products
Standard Practice for Automatic Sampling of Petroleum and Petroleum Products
SIGNIFICANCE AND USE
4.1 Representative samples of petroleum and petroleum products are required for the determination of chemical and physical properties, which are used to establish standard volumes, prices, and compliance with commercial terms and regulatory requirements. This practice does not cover sampling of electrical insulating oils and hydraulic fluids. This practice does not address how to sample crude at temperatures below the freezing point of water.
PART I—General
This part is applicable to all petroleum liquid sampling whether it be crude oil or refined products. Review this section before designing or installing any automatic sampling system.
SCOPE
1.1 This practice describes general procedures and equipment for automatically obtaining samples of liquid petroleum and petroleum products, crude oils, and intermediate products from the sample point into the primary container. This practice also provides additional specific information about sample container selection, preparation, and sample handling. If sampling is for the precise determination of volatility, use Practice D5842 (API MPMS Chapter 8.4) in conjunction with this practice. For sample mixing and handling, refer to Practice D5854 (API MPMS Chapter 8.3). This practice does not cover sampling of electrical insulating oils and hydraulic fluids.

1.3 Units—The values stated in either SI units or US Customary (USC) units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Except where there is no direct SI equivalent, such as for National Pipe Threads/diameters, or tubing.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

INTRODUCTION
The previous version of the automatic sampling practice described the design, installation, testing,
and operation of automated equipment for the extraction of representative samples from the flowing
stream and storing mainly for crude oil.
This practice is a performance-based standard. It still includes the design, installation, testing, and
operation of automated equipment for extraction of representative samples. It also includes the testing
and proving of a sampling system in the field under actual operating conditions to ensure that the
equipment, installation, and operating procedures produce representative samples. The acceptance
criteria for custody transfer are covered in this practice. This practice does not address how to sample
crude at temperatures below the freezing point of water. Extensive revisions have been made to the
prior version of D4177 (API MPMS Chapter 8.2).
This practice also provides guidance for periodic verification of the sampling system.
This practice is separated into three parts:
General—Sections 5 – 17 (Part I) are currently applicable to crude oil and refined products. Review
this section before designing or installing any automatic sampling system.
Crude Oil Sampling—Section 18 (Part II) contains additional information required to complete the
design, testing, and monitoring of a crude oil sampling system.
Refined Product Sampling—Section 19 (Part III) contains additional information required to
complete the design of a refined product sampling system.
A representative sample is “A portion extracted from the total volume that contains the constituents
in the same proportions that are present in that total volume.” Representative samples are required for
the determination of chemical and physical properties that are used to establish standard volumes,
prices, and compliance with commercial and regulatory specifications.
The process of obtaining a representative sample consists of the following: the physical equipment,
the correct matching of that equipment to the application, the adherence to procedures by the
operator(s) of that equipment, and the proper handling and analysis.
