ASTM D7149-05(2016)

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: D7149 − 05 (Reapproved 2011) D7149 − 05 (Reapproved 2016)
Standard Practice for
Determining the Freeze Thaw Stability of Adhesives
This standard is issued under the fixed designation D7149; 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.
ε NOTE—Units of measure were editorially corrected from hard to soft conversions in April 2011.
1. Scope
1.1 This practice determines the ability of an adhesive to withstand repeated freezing and thawing cycles at specific
temperatures without any significant change in physical properties.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This practice 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 practice to establish appropriate safety and health practices and determine the applicability of regulatory
limitation prior to use.
2. Referenced Documents
2.1 ASTM Standards:
D907 Terminology of Adhesives
D1084 Test Methods for Viscosity of Adhesives
D1293 Test Methods for pH of Water
D2556 Test Method for Apparent Viscosity of Adhesives Having Shear-Rate-Dependent Flow Properties Using Rotational
Viscometry
3. Terminology
3.1 Definitions:
3.1.1 Many of the terms utilized in this practice are defined in Terminology D907.
4. Significance and Use
4.1 This practice will provide a procedure for determining the stability of an adhesive to withstand five repeated cycles, or as
otherwise specified, of freezing and thawing at a specific temperature.
4.2 This practice will allow the user to determine whether or not the adhesive can be appropriately applied after cycling of
freezing and thawing.
4.3 This practice will identify any significant changes in the manufactured viscosity of the product after five cycles, or as
otherwise specified, of freezing and thawing at a specific temperature.
4.4 This practice will help determine if the pH of adhesive has changed significantly due to the freezing and thawing cycles.
5. Apparatus
5.1 A 1.0 L (1 qt) container, or larger, with lid. Other container sizes may be applicable for some adhesives.
5.2 Freezer capable of maintaining -18 6 -2°C (0.0 6 -5°F) to -7 6 -2°C (20 6 -5°F).
5.3 Brookfield RVT Viscometer 1-spindle TC at 5 – 20 rpms, Heliopath stand.
NOTE 1—Other viscometer models, their speed and spindle size, may be utilized as long as they comply to Test Methods D1084 or D2556 and are
recommended by the manufacturer for such use.
This practice is under the jurisdiction of ASTM Committee D14 on Adhesives and is the direct responsibility of Subcommittee D14.10 on Working Properties.
