UNBS is mandated to co- ordinate the elaboration of standards and is (a) a member of International Organisation for Standardisation (ISO) and (b) a contact point for the WHO/FAO Codex Alimentarius Commission on Food Standards, and (c) the National Enquiry Point on TBT Agreement of the World Trade Organisation (WTO). The work of preparing Uganda Standards is carried out through Technical Committees. A Technical Committee is established to deliberate on standards in a given field or area and consists of representatives of consumers, traders, academicians, manufacturers, government and other stakeholders. Draft Uganda Standards adopted by the Technical Committee are widely circulated to stakeholders and the general public for comments. The committee reviews the comments before recommending the draft standards for approval and declaration as Uganda Standards by the National Standards Council. This Final Draft Uganda Standard, FDUS 1726: 2017, Standard Test Method for Density, Relative Density, or API Gravity of Crude Petroleum and Liquid Petroleum Products by Hydrometer Method, is based on ASTM D1298 − 12b, Standard Test Method for Density, Relative Density, or API Gravity of Crude Petroleum and Liquid Petroleum Products by Hydrometer Method, Copyright ASTM International, 100 Barr Harbor Drive, West Conshohocken, PA 19428, USA, pursuant to license with ASTM International. The committee responsible for this document is Technical Committee UNBS/TC 16, Petroleum, Subcommittee SC 1, Petroleum and petrochemical products. Wherever the words, “ASTM Standard" appear, they should be replaced by "Uganda Standard."
