ASTM E2189-19 PDF

Full title and description

Standard Test Method for Testing Resistance to Fogging in Insulating Glass Units — a procedural test method that specifies how to evaluate and report the tendency of preassembled insulating glass units (IGUs) to form internal fogging (condensation or haze) caused by volatile components within the unit or its seal system.

Abstract

This test method provides a repeatable procedure for exposing insulating glass units (double- and triple-glazed, with glass or suspended film) to controlled conditions and observing/recording fogging behavior caused by internal volatile components (for example sealant or spacer volatiles or internal decorative films). It defines specimen requirements, test conditions, and reporting conventions so manufacturers, test laboratories, and specifiers can evaluate resistance to internal fogging.

Scope

The standard covers procedures for testing the resistance to fogging of preassembled permanently sealed insulating glass units or IGUs with capillary tubes intentionally left open or closed. It applies to IGUs constructed with glass or suspended film and to both double-glazed and triple-glazed units (including configurations where an inner lite may be a suspended film). The method notes construction-dependent limitations (different glass types, thicknesses, and cavity sizes can affect results) and excludes certain configurations such as IGUs containing spandrel glass coatings due to testing limitations.

Key topics and requirements

• Specimen selection and preparation for double- and triple-glazed IGUs (minimum specimen counts and construction requirements).
• Controlled exposure and observation procedures to detect and record fogging (including environmental conditioning and viewing methods).
• Identification of internal volatile sources (sealants, spacers, films, decorative components) and their role in fogging behavior.
• Limitations and exclusions (for example, spandrel-coated IGUs are not covered; results depend on unit construction and materials).
• Reporting conventions and criteria to support product evaluation, QA, and comparative testing.

Typical use and users

Used by IGU manufacturers, independent testing laboratories, product development teams, quality assurance groups, glazing specifiers, architects, and building envelope consultants to evaluate and document resistance to internal fogging and to support product claims, troubleshooting, and specification decisions.

Related standards

Commonly referenced alongside other insulating-glass standards and test methods, notably ASTM E2188 (Test Method for Insulating Glass Unit Performance) and ASTM E2190 (Specification for Insulating Glass Unit Performance and Evaluation), which cover related performance and evaluation topics for IGUs. These documents together form a suite of guidance used for IGU performance assessment.

FAQ

Q: What is this standard?

A: ASTM E2189-19 is a test method that specifies how to test insulating glass units for resistance to internal fogging (formation of haze or condensation caused by volatile components inside the sealed unit).

Q: What does it cover?

A: It covers test specimen requirements, conditioning and exposure procedures, observation and evaluation of fogging, reporting practices, and applicable limitations (applicable to IGUs with glass or suspended film; not applicable to some spandrel-coated units).

Q: Who typically uses it?

A: IGU manufacturers, third‑party test laboratories, product development and QA teams, glazing specifiers, architects, and consultants who need a standardized method to assess fogging resistance.

Q: Is it current or superseded?

A: The current documented edition is E2189-19, published 1 April 2019. Searches of document listings and catalog entries show E2189-19 as the active revision; no later superseding edition was found in the consulted catalogs at the time of this summary. Users who need legal or procurement certainty should confirm status directly with ASTM or their standards provider.

Q: Is it part of a series?

A: Yes — E2189 is part of a family of IGU-related standards managed by ASTM Committee E06 (Performance of Buildings) and subcommittee E06.22. It is typically used with related documents such as ASTM E2188 and E2190 for broader IGU performance and specification work.

Q: What are the key keywords?

A: fogging, insulating glass units (IGU), condensation, sealant volatiles, spacer volatiles, suspended film, double-glazed, triple-glazed, IGU performance.
