NATO Supply Class 6635 is a classification within NATO Supply Group 66, which is dedicated to Instruments And Laboratory Equipment.

NATO Supply Class 6635 specifically focuses on Physical Properties Testing And Inspection. This class includes a wide range of instruments and equipment used for testing and inspecting the physical properties of various materials and substances.

Some examples of items that fall under NATO Supply Class 6635 include:

1. Analytical balances: These are precision instruments used to measure the mass of substances with high accuracy.

2. Viscometers: These instruments are used to measure the viscosity or flow properties of liquids.

3. Tensile testing machines: These machines are used to determine the tensile strength and other mechanical properties of materials.

4. Thermometers: Various types of thermometers, such as mercury-in-glass thermometers or digital thermometers, are used to measure temperature.

5. pH meters: These instruments are used to measure the acidity or alkalinity of a solution.

6. Spectrophotometers: These devices are used to measure the intensity of light at different wavelengths, allowing for the analysis of substances based on their absorption or emission of light.

7. Gas chromatographs: These instruments are used to separate and analyze the components of a gas mixture.

These are just a few examples of the types of instruments and equipment that fall under NATO Supply Class 6635. The class encompasses a wide range of tools used for testing and inspecting the physical properties of materials in laboratory and industrial settings.
