The process of measuring the Electrical Conductivity of a Solution or a device.

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

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)

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

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.

Measuring the ratio of the water vapor’s partial pressure divided by the saturation water vapor pressure allowed at a given temperature.

The process of measuring the physical temperature of a device.

The process of measuring the physical temperature from a block body that will be used to generate infrared temperatures.

The process of measuring the simulated temperature in voltage from a RTD device.

The process of measuring the simulated temperature in voltage from a thermocouple device.

This process sources a reference mass flow rate of gas for calibrating gas-flow meters. The instantaneous mass flow rate q_m equals dm/dt, sometimes estimated as ∆m/∆t using the total mass ∆m flowing through a defined surface in time ∆t.

The process of generating a physical temperature to be measured by a device.

The process of generating an infrared temperature on a block body to be measured by an infrared measuring device.

The process of generating resistance simulating temperature to be measured by an RTD temperature measuring device.
