The relevant organisations are summarised below :

1.1. DEPARTMENT OF TRADE AND INDUSTRY (OIL AND GAS OFFICE) Abbrev : DTI or DTI (OGO) Website : www.og.dti.gov.uk The DTI Oil & Gas division have issued “Guidance Notes For Petroleum Measurement Under The Petroleum (Production) Regulations, which apply to the British sector.

1.2. INSTITUTE OF PETROLEUM Abbrev : IP Website : www.petroleum.co.uk A number of standards/guidelines are published by the IP which relate to the handling and measurement of Petroleum Products. The Institute of Petroleum maintains a 18 part “Manual of Petroleum Measurement” and 11 of “Petroleum Measurement Papers”. Reference to the manual is made in the following format, “IP part** section **” where “**” will be the numerical reference. The Institute of Petroleum also maintains a “Model Code of Safe Practice in the Petroleum Industry.

1.3. AMERICAN PETROLEUM INSTITUTE Abbrev : API Website : www.api.org The American Petroleum Institute maintains a 21 chapter “Manual of Petroleum Measurement Standards”. Reference to this manual is made in the following format, “API MPM chapter ***” where *** will be the numerical reference. Additional API standards are published under the ANSI four digit numbering system. These are referred to as API ****.

1.5. BRITISH STANDARDS INSTITUTE

www.bsi-global.comAbbrev : BS Website : The British Standards Institute incorporates applicable ISO standards in the BS numbering system. Certain standards are reissued verbatim but many (eg. ISO 5167/BS 1042 section 1.1) are technical equivalents where minor detail changes have been made. Many British Standards are now harmonised with ISO CEN, CENELEC, or IEC standards and are published as:- BS ISO BS EN European Standards (CEN / CENELEC) BS IEC International Electrotechnical Commission BS PD Published Document
