ISO 20492-1:2008 establishes two methods for testing the durability of edge seals of insulating glass units by means of climate tests. The two methods are designated as approach 1 for markets such as North America and approach 2 for markets such as Europe. ISO 20492-1:2008 is applicable to pre-assembled, permanently sealed, insulating glass units with one or two airspaces, and with capillary tubes that are intentionally left open to equalize pressure inside the unit with the surrounding atmosphere. ISO 20492-1:2008 is not applicable to sealed, insulating glass units that contain a spandrel glass coating. ISO 20492-1:2008 does not apply to insulating glass units whose function is decorative only.

Abstract

Overview

ISO 20492-1:2008 - "Glass in buildings - Insulating glass - Part 1: Durability of edge seals by climate tests" specifies laboratory climate test methods to assess the durability of edge seals in pre-assembled, permanently sealed insulating glass units (IGUs). The standard defines two approaches tailored to different markets: Approach 1 (e.g., North America) and Approach 2 (e.g., Europe). It applies to IGUs with one or two airspaces and to units with intentionally open capillary tubes to equalize pressure, but it excludes IGUs with spandrel coatings and IGUs intended solely for decorative use.

Key topics and technical requirements

Two testing approaches
- Approach 1 (frost/dew point): Measures final frost/dew point after pre-conditioning, weather cycling (temperature, humidity, UV) and final conditioning. Final frost/dew point of each airspace must be −40 °C or colder when measured per ASTM E546 or equivalent.
- Approach 2 (moisture-penetration index): Uses a moisture-penetration index (I). The average I across five specimens must not exceed 0.20; the worst specimen must not exceed 0.25.
Test specimen requirements
- Typical specimen size: (355 ± 6) mm × (505 ± 6) mm.
- Double- and triple-glazed configurations with specified glass and airspace thicknesses (examples provided for double- and triple-glazed specimens).
- Marking: manufacturer ID, fabrication date, intended orientation for field installation.
- Vertical storage and support during testing; spare specimens recommended for breakage.
Test method elements
- High-humidity conditioning, weather-cycling chambers, frost/dew point measurement, and methods for moisture measurement (including desiccant evaluation and Karl Fischer/950 °C drying methods in normative annexes).
Limitations
- Not intended for IGUs exposed to long-term immersion or for some coated/absorptive products that can exceed sealant temperature limits.

Practical applications and users

Intended users:
- Insulating glass (IGU) manufacturers for product qualification and quality control.
