DEFINITION

Classification: 436/8

COMPOSITIONS FOR STANDARDIZATION, CALIBRATION, SIMULATION, STABILIZATION, PREPARATION OR PRESERVATION: PROCESSES OF USE IN PREPARATION FOR CHEMICAL TESTING:

(under the class definition) Compositions which are used to mimic or quantify the effect, in a chemical test procedure, of another chemical composition, or to stabilize, preserve or otherwise prepare a sample for a chemical test and the processes of use of such materials preparatory to a chemical test procedure.

(1) Note. This and the indented subclasses resulted from the incorporation of Class 252, subclass 408.1, into this class. The user is cautioned that a claim to a composition provided for in Class 252 e.g., a lubricant with a test agent, etc., will be provided for in Class 252 absent a claim to a test method.

(2) Note. This and the indented subclasses provide for a test in which a substance which produces a standardized result is used in place of the actual specie to be tested for.

(3) Note. This and the indented subclasses do not provide for original placement of a process which includes the test for the actual specie or species of interest.

252, Compositions,

408.1, for physical test standards.

324, Electricity: Measuring and Testing, 308, and 317 for the use of a control sample in nuclear resonance spectrometry and electron resonance spectrometry.

356, Optics: Measuring and Testing, various subclasses for use of standards in a process of optical testing particularly

42, for optical blood standards; subclass 46, for light standards, per se; subclass 243, for optical standards generally; subclass 412, for colorimeters which utilize a solid or liquid transmissive standard; subclass 420, for a colored light source used as a standard and 421 for reflective light standards.

516, Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting, appropriate subclasses for subject matter

relating to: colloid systems (such as sols*, emulsions, dispersions, foams, aerosols, smokes, gels, or pastes) or wetting agents (such as leveling, penetrating, or spreading); subcombination compositions of colloid systems containing at least an agent specialized and designed for or peculiar to use in making or stabilizing colloid systems; compositions and subcombination compositions specialized and designed for or peculiar to use in breaking (resolving) or inhibiting colloid systems; processes of making the compositions or systems of the class; processes of breaking (resolving) or inhibiting colloid systems; in each instance, when generically claimed or there is no art class. Class 516 provides for compositions otherwise seemingly proper for Class 436 when the compositions are colloid systems or wetting agents.
