Standard Test Method for
Resin Solution Dilutability by Volumetric/Gravimetric
Determination1
This standard is issued under the fixed designation D 5062; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of the last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method covers both volumetric and gravimetric
determination of resin solution dilatability which gives a
the numerical value for the overall solubility of the resin expressed
as percent dilutability.
1.2 This test method is applicable only if the test solution is
of sufficient clarity to allow accurate visual judgment of the
endpoint and of low enough viscosity for efficient mixing to
take place.
1.3 This test method is primarily for, but not limited to,
resins used in the printing ink industry.
1.4 The percent solvent tolerance of a resin can be determined using this test method if the solvent in the resin solution
and the dilution solvent is the same.
1.5 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Terminology
3.1 Definition of Term Specific to This Standard:
3.1.1 resin solution dilatability—the maximum amount of
diluent tolerated to reach a defined degree of turbidity; beyond
this point, resin precipitation will occur.
4. Summary of Test Method
4.1 A sample of resin solution is weighed into a glass beaker
that is placed over a piece of 10-point print (standard
newspaper print).
4.2 The dilution solvent is added slowly from a buret until
