Scope: This standard specifies manual sampling methods for taking samples of liquid or semi-liquid hydrocarbons, tank residues, and sediments from stationary tanks, railroad tank cars, automobile tank cars, ships, drums, cans, pumped liquid lines, or dispenser nozzles. This standard applies to the sampling of petroleum products, crude oil and intermediate products stored in oil tanks at or near atmospheric pressure or transported by pipelines, and stored and transported in liquid form at room temperature to 200 °C. This standard does not apply to the sampling of special petroleum products that are research objects of other standards, such as electrical insulating oil (IEC 60475), liquefied petroleum gas (SH/T 0233), liquefied natural gas (GB/T 20603) and gaseous natural gas (GB/T T 13609). This standard covers existing sampling methods and types of equipment in use. For the new equipment that appears later, as long as it can be sampled according to the requirements and methods of this standard, it can also be used in this standard.
