ASTM C1285-14

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.

Standard Test Methods for
Determining Chemical Durability of Nuclear, Hazardous, and
Mixed Waste Glasses and Multiphase Glass Ceramics: The
1
Product Consistency Test (PCT)
This standard is issued under the fixed designation C1285; 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 These product consistency test methods A and B evaluate provide a measure of the chemical durability of homogeneous
glasses, phase separated glasses, devitrified glasses, glass ceramics, and/or multiphase glass ceramic waste forms forms, or
combinations thereof, hereafter collectively referred to as “glass waste forms” by measuring the concentrations of the chemical
species released to a test solution.solution under carefully controlled conditions.
1.1.1 Test Method A is a seven-day chemical durability test performed at 90 6 2°C in a leachant of ASTM-Type I water. The
2
test method is static and conducted in stainless steel vessels. The stainless steel vessels require a gasket to remain leak-tight. The
stainless steel vessels are considered to be “closed system” tests. Test Method A can specifically be used to evaluate whether the
chemical durability and elemental release characteristics of nuclear, hazardous, and mixed glass waste forms have been
consistently controlled during production. This test method is applicable to radioactive and simulated glass waste forms as defined
above.
1.1.2 Test Method B is a durability test that allows testing at various test durations, test temperatures, mesh size, mass of particle
size and masses of glass sample, leachant volume,volumes, and leachant compositions. This test method is static and can be
conducted in stainless steel or PFA TFE-fluorocarbon vessels, or both. vessels. The stainless steel vessels are considered to be
“closed system” while the PFA TFE-fluorocarbon vessels are considered to be “open system” tests. Test Method B can specifically
be used to evaluate the relative chemical durability characteristics of homogeneous glasses, phase separated glasses, devitrified
glasses, glass ceramics, and/oror multiphase glass ceramic waste forms. forms, or combinations thereof. This test method is
applicable to radioactive (nuclear) and mixed, hazardous, and simulated glass waste forms as defined above. Test Method B cannot
be used as a consistency test for production of high level radioactive glass waste forms.
1.2 These test methods must be performed in accordance with all quality assurance requirements for acceptance of the data.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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.

TFE-fluorocarbon gaskets, available commercially, are acceptable and chemically inert up to radiation doses of 1 × 10 R of beta or gamma radiation which have been
shown not to damage TFE-fluorocarbon. If higher radiation doses are anticipated, special gaskets fabricated from metals such as copper, gold, lead, or indium are
recommended.
