ASTM C676-04(2009)

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation:C676–93 (Reapproved 1999) Designation:C676–04 (Reapproved 2009)
Standard Test Method for
Detergent Resistance of Ceramic Decorations on Glass
Tableware
This standard is issued under the fixed designation C 676; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This qualitative test method is designed to provide a convenient and reproducible method of determining the detergent
resistance of decorations applied to glass tableware.
1.2 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.
2. Referenced Documents
2.1 ASTM Standards:
C 927 Test Method for Lead and Cadmium Extracted from the Lip and RimArea of Glass Tumblers Externally Decorated with
Ceramic Glass Enamels
3. Terminology
3.1 Definition:
3.2 detergent resistance—the degree of resistance to the chemical action of detergents.
4. Significance and Use
4.1 This test method provides a means of estimating the qualitative performance of glass enamel decorations that are exposed
to high phosphate detergents during use. This test method also attempts to simulate accelerated exposure to high phosphate
detergents prior to testing for heavy metal release, such as in Test Method C 927 when long term performance of enamels must
be evaluated.
5. Apparatus
5.1 Test Chamber—A thermostatically controlled tank, preferably stainless steel, that will maintain a solution temperature of
60 6 2°C.
5.2 Specimen Holder—A device for supporting the speci-mens to be evaluated in such a manner as to ensure free and
unobstructed contact between the decoration and the test solution.
6. Test Specimens
6.1 Test specimens consist of representative glass tableware with ceramic decorations.
7. Test Solution
7.1 Prepare a test solution consisting of 5 % sodium pyrophosphate (Na P O ·10H O) and 95 % distilled water.

8. Procedure
8.1 Immerse the samples for 2-h periods in the test solution maintained at 60 6 2°C. Retain a duplicate piece of ware with each
decoration under test without exposure to the solution as an aid in judging the degree of chemical action on the specimens under
test.At the end of the 2-h periods, remove the specimens from the solution, rub vigorously with a cloth under running water, dry,
and evaluate.
This test method is under the jurisdiction ofASTM Committee C-14 C14 on Glass and Glass Products and is the direct responsibility of Subcommittee C14.10 on Glass
Decoration in cooperation with the Society of Glass Decorators’ Committee A-20.
