Scope: This standard specifies the method for measuring the standard density of liquid crude oil, petroleum products, and mixtures of petroleum products and non-petroleum products in the laboratory using a weighing digital dis lay liquid density meter (hereinafter referred to as a weighing density meter). This standard is applicable to the determination of crude oil and liquid petroleum products with a Reid vapor pressure (RVP) less than 100kPa. This standard is suitable for determining the density of liquids with sufficient fluidity. For liquids that are solid at room temperature or do not flow easily, a suitable constant temperature bath can be used to measure the density of these liquids above room temperature. This standard is applicable to weighing density meters that are calibrated when the calibration liquid is 20°C and whose apparent density is not corrected for thermal expansion of the float during actual measurement.
