ASTM E90

ASTM E90 is the ASTM standard for laboratory measurement of airborne sound transmission loss of building partitions and elements. It helps define a consistent test approach for evaluating how well a wall, floor, door, or related building component resists sound passing through it in a controlled setting. This makes the standard important for product comparison, specification review, and performance documentation when acoustic separation is a key design concern.

Purpose of ASTM E90

The purpose of ASTM E90 is to provide a recognized laboratory test method for measuring airborne sound transmission loss in building partitions and elements. By using a controlled procedure, the standard supports repeatable results that can be used to compare products and assemblies on a consistent basis. It is commonly relied on when acoustic performance needs to be documented for design decisions, submittals, or compliance-related review. ASTM E90 helps reduce uncertainty in how sound transmission performance is measured.

Common use cases of ASTM E90

This standard is commonly used for laboratory evaluation of building assemblies such as partitions and related elements where airborne sound control is important. It is often referenced in product testing, quality control, and technical documentation for components intended to limit sound transfer between spaces. ASTM E90 may also support procurement and specification work when project teams need comparable acoustic test data for building materials or systems before selection or approval.

Why ASTM E90 matters

ASTM E90 matters because consistent laboratory sound transmission testing supports clearer product evaluation and more reliable performance claims. For manufacturers, designers, and specifiers, the standard helps align testing methods so results are easier to compare across different assemblies and test reports. That consistency can improve compliance review, reduce misinterpretation of acoustic data, and support better decisions when selecting partitions or elements for sound-sensitive building applications. ASTM E90 is therefore a practical tool for risk reduction and quality assurance.
