ASTM E2190-19 PDF

Full title and description

ASTM E2190-19 — Standard Specification for Insulating Glass Unit Performance and Evaluation. This specification defines qualification criteria and evaluation procedures for preassembled, permanently sealed insulating glass units (IGUs), including double- and triple-glazed units and argon-filled units, with requirements based on frost/dew point and absence of fog after specified test durations.

Abstract

Provides performance and evaluation requirements intended to assess the durability of sealed insulating glass units (IGUs). The standard applies to IGUs constructed with glass (or suspended film) and covers hermetically sealed units with one or two cavities (and units with capillary tubes intentionally left open or closed). It is intended to be used alongside ASTM test methods (for example E2188 and E2189) to qualify IGU assemblies for resistance to fogging and gas retention; it does not address aesthetic, thermal, optical, or structural glazing design decisions.

Scope

Covers preassembled, permanently sealed insulating glass units with one or two cavities, including units with capillary tubes intentionally left open or closed; applies to IGUs constructed with glass or suspended film and to both double- and triple-glazed configurations (where applicable). Qualification is based on frost/dew point criteria and the absence of fog after required test exposures; argon-filled IGUs are qualified by demonstrating retention of specified argon amounts before and after testing to referenced test methods. The specification excludes requirements for appearance, thermophysical properties, heat/light transmission, glass displacement, and is not a substitute for structural sealant glazing requirements.

Key topics and requirements

• Qualification criteria based on frost/dew point and visual absence of fogging after accelerated durability tests.
• Requirements for argon-filled IGUs to demonstrate gas retention (linked to Test Methods E2188, E2269, E2649 as applicable).
• Applicability to double- and triple-glazed IGUs and to units containing glass or suspended film.
• Exclusions: spandrel-coated IGUs (due to test limitations), structural-glazing suitability is not automatically implied by passing this specification — sealant longevity and structural properties must be reviewed separately.
• Reference and reliance on related ASTM test methods (E2188, E2189, E546, etc.) for specific test procedures and measurements used in qualification.

Typical use and users

Used by IGU manufacturers and fabricators, independent test laboratories, product certifiers, architects and façade engineers specifying window and curtain-wall systems, glazing contractors, building code officials, and procurement/specification teams who need a durability-based qualification for sealed insulating glass units intended for building vision areas. It is commonly required for products exported to or specified within markets that reference ASTM IGU testing.

FAQ

Q: What is this standard?

A: ASTM E2190-19 is a specification that establishes performance and evaluation criteria to qualify sealed insulating glass units (IGUs) for durability and resistance to fogging and gas loss.

Q: What does it cover?

A: It covers preassembled permanently sealed IGUs with one or two cavities (including certain capillary-tube constructions) made with glass or suspended film, and sets pass/fail qualification based on frost/dew point measurements and absence of fog after required test exposures. It does not specify optical, thermal, appearance, or structural design requirements.

Q: Who typically uses it?

A: Manufacturers, test labs, certifiers, architects, façade engineers, glazing contractors, and code/specification professionals who need a recognized durability qualification for IGUs.

Q: Is it current or superseded?

A: The 2019 revision (E2190-19) is the published edition referenced here; the standard was approved in 2019 and is listed as the current edition in standards summaries. Users should verify with ASTM for any subsequent revisions or reapprovals.

Q: Is it part of a series?

A: Yes — E2190 is typically used together with related ASTM test methods and guides (for example E2188 and E2189 for IGU performance testing, E546 for frost/dew point testing, and C1369/C1249 where structural sealant considerations are required).

Q: What are the key keywords?
