ASTM E1425-14 (2023) PDF

Full title and description

Designation: ASTM E1425-14 (Reapproved 2023) — Standard Practice for Determining the Acoustical Performance of Windows, Doors, Skylight, and Glazed Wall Systems. This practice establishes test methods, specimen criteria, and a classification/rating system for measuring and reporting the acoustical performance (including sound transmission loss) of fenestration and glazed wall assemblies, and also addresses concurrent measurement and reporting of operating force, latching force, and air leakage when applicable.

Abstract

ASTM E1425-14(2023) defines a standardized laboratory practice for evaluating the acoustical performance of windows, doors, skylights and glazed wall systems. It specifies specimen preparation requirements, the sequence of tests (operating force, latching force, air leakage, then sound transmission loss), reporting conventions, and a classification/rating approach so manufacturers, specifiers and approving authorities can compare acoustical performance across products. The practice is a reapproval of the 2014 edition and was reapproved/published in 2023.

Scope

This practice establishes the test methodology, specimen criteria, and classification/rating system for determining acoustical performance levels of windows, doors, skylights, and glazed wall systems only (not for through-openings between such assemblies and adjacent construction). When applicable, the practice requires concurrent testing and reporting of operating force, latching force, and air leakage in addition to sound transmission loss. Values in inch–pound units are standard; SI conversions are informational.

Key topics and requirements

• Defined sequence of tests: operating force (if applicable) → latching force (if applicable) → air leakage → sound transmission loss.
• Specimen preparation and size limits appropriate to windows, doors, skylights and glazed wall systems; specimens should be representative of production units.
• Reporting of air leakage and operating/latching forces alongside acoustical ratings to inform trade-offs between airtightness, operability, and sound performance.
• Use of established acoustical classification metrics (e.g., STC and OITC where applicable) and alignment with related acoustical test methods.
• Units and tolerances: inch–pound units treated as standard; SI conversions provided for information only.
• Jurisdiction: prepared under ASTM Committee E06 (Subcommittee E06.51) — Performance of Windows, Doors, Skylights and Curtain Walls.

Typical use and users

Used by fenestration and glazed-wall manufacturers, independent acoustical and building-test laboratories, architectural and acoustic consultants, building code and approving authorities, product certification bodies, and specification writers to evaluate, classify, compare, and specify the acoustical performance of windows, doors, skylights and glazed wall assemblies. The practice helps manufacturers communicate product acoustical ratings and helps specifiers judge trade-offs between sound performance and other attributes such as air leakage and operability.

Related standards

Commonly referenced and complementary ASTM standards include: E90 (Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions and Elements), E283 (Test Method for Determining Rate of Air Leakage), E413 (Classification for Rating Sound Insulation), E1332 (Classifications such as OITC/STC), and relevant terminology standards. The practice also cross-references fenestration industry documents and other test/ratings standards used by industry groups.

Q: Who typically uses it?

A: Manufacturers, test laboratories, acoustical and architectural consultants, certifiers, and approving authorities use this practice for product evaluation, specification and comparison.

Q: Is it current or superseded?

A: The 2014 edition (E1425-14) was reapproved in 2023 and is listed as the current/reapproved practice (document references use E1425-14R23 or E1425-14 (2023)).

Q: Is it part of a series?

A: It is part of ASTM Committee E06’s field of standards on building and fenestration performance and is a practice that complements related acoustics, air leakage and classification standards (for example E90, E283, E413, E1332).

Q: What are the key keywords?
