14、lisher.ForewordThis publication was prepared jointly by the American Petroleum Institute Committee on Petroleum Measurement and the Energy Institute Hydrocarbon Management Committee.The American Petroleum Institute Committee on Petroleum Measurement (COPM) and the Energy Institutes Hydrocarbon Manag

15、ement Committee (HMC) are responsible for the production and maintenance of standards and guides covering various aspects of static and dynamic measurement of petroleum. The API/EI Joint Committee on Hydrocarbon Management (JCHM), its sub-committees and work groups consist of technical specialists r

16、epresenting oil companies, equipment manufacturers, service companies, terminal and ship owners and operators. The API/EI JCHM encourages international participation and when producing publications its aim is to represent the best consensus of international technical expertise and good practice. Thi

17、s is the main reason behind the production of joint publications involving cooperation with experts from both the API and EI.This standard is intended to provide guidelines for measurement and sampling of cargoes on board tank vessels using closed and restricted equipment. However, it is not intende

18、d to preclude the use or development of any other technologies or methods. To gain a better understanding of the methods described in this standard, the reader should review in detail the latest editions of the publications, standards and documents referenced herein.SI units are used throughout this

19、 publication as the primary units of measure since this system is commonly used in measurement and sampling. However, US Customary (USC) units continue to be used in some applications. Therefore, both SI and USC units are shown (with USC in parentheses). This standard is not intended to supersede an

20、y safety or operating practices recommended by organisations such as the International Maritime Organization (IMO), International Safety Guide for Oil Tankers and Terminals (ISGOTT), International Chamber of Shipping (ICS) and Oil Companies International Marine Forum (OCIMF), or individual operating

21、 companies, nor is the publication intended to supersede any other safety or environmental considerations, local regulations, or the specific provisions of any contract.All shipboard procedures described in this standard should be performed by or in the presence of the ships master, or their designa

22、ted representatives. For reasons of safety, only approved equipment certified intrinsically safe or otherwise approved suitable for its intended use shall be used.API/EI standards are published as an aid to procurement of standardised equipment and materials and/or as good practice procedures. These

23、 standards are not intended to inhibit purchasers or producers from purchasing or producing products made to specifications other than those of API or EI.Classified areas may vary depending on the location, conditions, equipment, and substances involved in any given situation. Users of this standard

24、 should consult with the appropriate authorities having jurisdiction. Users of this standard should not rely exclusively on the information contained in this publication. Sound business, scientific, engineering, and safety judgment should be used in employing the information contained herein.Shall:
