DEFINITION

Classification: 148/508

With measuring, testing, or sensing:

(under subclass 95) Process which includes a step involving measuring, testing, or sensing of a reaction condition.

(1) Note. The adjustment of a condition to a specified level (e.g., temperature) is not proper hereinunder unless there is an actual recitation in the claim of measuring, testing or sensing.

324, Electricity: Measuring and Testing, appropriate subclasses for processes of determining electrical properties by electrical means, per se, even though nonelectrical values are derived from the electrical values determined.

356, Optics: Measuring and Testing, appropriate subclasses for processes which utilize visible light to measure optical properties, per se, or for processes of testing visible light for optical properties and which utilize visible light to test for nonoptical properties, per se, when not elsewhere provided.

374, Thermal Measuring and Testing, appropriate subclasses for thermal testing, per se, or the combination of thermal testing and nonthermal testing, per se.
