ASTM C1294-07
(Test Method)Standard Test Method for Compatibility of Insulating Glass Edge Sealants with Liquid-Applied Glazing Materials
Standard Test Method for Compatibility of Insulating Glass Edge Sealants with Liquid-Applied Glazing Materials
SCOPE
1.1 This test method covers a laboratory procedure for quantitatively measuring the compatibility of liquid-applied glazing materials with an insulating glass unit edge sealant. Compatibility is determined by measuring the changes in the insulating glass edge sealant adhesive and cohesive properties. Hereinafter insulating glass is referred to as IG.
1.2 This test method does not address the issue of the integrity of the hermetic seal or changes to the vision area in an IG unit. Such factors as possible unit fogging or primary sealant reaction in a dual-seal system due to volatile components permeating the IG sealant are not considered in this test method.
1.3 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.
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.

3. Terminology
3.1 Definitions—Refer to Terminology C717 for definitions of the following terms: adhesive failure, cohesive failure,
compatibility, compound, elongation, glazing, seal, sealant, substrate.
4. Summary of Test Method
4.1 This test method includes the measurement of tensile force, elongation, and percent cohesive or adhesive failure and
observations of the specimen’s general physical appearance and observation of elongation.
4.2 Test specimens are exposed to 70°C (158°F) heat for four weeks while contacting the liquid-applied glazing material being
evaluated.
4.2.1 Control specimens are exposed only to the 70°C (158°F) heat.
4.3 Compatibility is determined by comparing the measured and observed properties of the test specimens to the control
samples.
5. Significance and Use
5.1 Liquid-applied glazing materials, bedding sealants, glazing compounds (that is, glazing sealants) are designed to provide a
seal between the IG unit and the window or wall framing. Frequently there is physical contact between these materials and an IG
unit edge sealant. Depending on the particular IG unit edge sealant, there can be a detrimental physical or chemical interaction
between it and the liquid-applied glazing material. Detrimental effects may include: weakening, softening, hardening, or adhesive
failure of the IG edge sealant, or visual obstruction inside the IG unit.
