Test Process that measures the quantity of matter which a body contains, as measured by its acceleration under a given force or by the force exerted on it by a gravitational field.
The term “mass” is always used in the strict Newtonian sense as a property intrinsic to matter. Mass is the proportionality constant between a force on a material object and its resulting acceleration. This property is sometimes referred to as “true mass”, “vacuum mass”, or “mass in a vacuum” to distinguish it from conventional [apparent] mass.
The true quantity of matter represented in a vacuum with no gravitational force.

Test Process that measures the relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, air at room temperature (20 °C or 68 °F) is the reference. The term “relative density” is often preferred in scientific usage. It is defined as a ratio of the density of a particular substance with that of water.
Required Parameters
- Density Ratio {kg·m3/kg·m3 g·cm3/g·cm3, lb·ft3/lb·ft3}
- Reference material {Water , Air}

Test Process that measures a solid’s density as defined by the amount of mass present in a specified volume temperature. Temperature affects density as solids expand and contract according to their temperature coefficients.
** Includes voids and non-uniformity
Required Parameters
- Density {kg·m3, g·cm3, lb·ft3}
- Temperature
Optional Parameters
- Nominal Height
- Nominal Length
- Nominal Width
- Nominal Volume
- Mass

Test Process that measures a liquid’s density as defined by the amount of mass present in a specified volume of liquid at a given temperature. Temperature affects density, as does the pressure to the extent that the liquid compresses. In, liquids deemed sufficiently incompressible, the volume does not depend on pressure.
** Includes non-uniformity and voids (if any)
Required Parameters
- Density {kg·m3, g·cm3, lb·ft3}
- Temperature
Optional Parameters
Measured Value & Uncertainty
- Density {kg·m3, g·cm3, lb·ft3}
Test Process that measures a gas’s density as defined by the amount of mass present in a specified volume of gas at a given temperature and pressure.
Gases are extremely responsive to temperature and pressure, causing their densities to change rather quickly. Measuring the density of gas the Ideal Gas Law (P*V = nRT) must be taken into account.
** Includes non-uniformity
Required Parameters
- Density {kg·m3, g·cm3, lb·ft3}
- Pressure
- Temperature
Optional Parameters
Measured Value & Uncertainty
- Density {kg·m3, g·cm3, lb·ft3}
This test process generates the pneumatic absolute pressure to be measured by the unit under test. The resulting measured will be in the unit of measure as defined in the test point’s data.
Note: Although the unit of measure can be read from the test point’s unit of measure it is good practice to pass the Unit of Measure to the test process as a parameter to avoid confusion when synchronizing data between systems.
