(Practice)Standard Practices for Mounting Test Specimens for Sound Transmission Loss Testing of Naval and Marine Ship Bulkhead Treatment Materials
Standard Practices for Mounting Test Specimens for Sound Transmission Loss Testing of Naval and Marine Ship Bulkhead Treatment Materials
SIGNIFICANCE AND USE
3.1 The sound transmission loss provided by a material that covers a flat surface depends not only on the physical properties of the material but also on the type of structure to which it is mounted and the mounting method used.
3.2 Naval and marine architects and design engineers require specific transmission loss characteristics of acoustical treatment materials as they would exhibit installed on a ship's structure. The mounting structure and procedures specified in these practices are intended to simulate such a shipboard environment.
3.3 Test reports may refer to this mounting by Practices E1123 instead of providing a detailed description of the mounting used.
SCOPE
1.1 These practices describe test specimen mountings to be used for naval and marine ship applications during sound transmission loss tests performed in accordance with Test Method E90.
1.2 The structure specified in these practices is intended for mounting of single-layer treatments or composite treatments consisting of various materials and configurations. Acoustical treatment materials may be combinations of acoustical absorbent materials, limp mass septums, and insulation materials.
1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM E1123-86(2023) is the internationally recognized standard for mounting test specimens during sound transmission loss testing of naval and marine ship bulkhead treatment materials. Developed by ASTM International, this standard ensures consistent and accurate simulation of shipboard conditions when evaluating the acoustical performance of bulkhead treatment systems. The standard outlines all required mounting structures, installation methods, and specimen configurations essential for reliable sound transmission loss measurements, especially in conjunction with ASTM E90 test methods.
Key Topics
Sound Transmission Loss in Marine Environments
The transmission loss characteristics of materials depend not only on their physical properties but also on the mounting method and underlying structure. ASTM E1123 details these mounting practices to best replicate real-world shipboard environments.Standardized Mounting Structure
- Specifies use of a fabricated aluminum bulkhead fitting a 2.44-meter (8-ft) test opening
- Bulkhead consists of two sections joined with an aluminum I-beam, supported by tee beams for rigidity
- Mounting includes self-adhesive stud pins, proper spacing patterns, and reinforcement details to ensure repeatability
Acoustical Treatment Material Application
- Supports both single-layer and composite treatment systems, using combinations such as acoustic absorbents, limp mass septums, and insulation materials
- Details secure mounting with self-locking washers, pin placement, and seam treatments to correctly represent field installations
Reporting and Compliance
- Provides guidance for documenting practices in test reports as "in accordance with ASTM E1123" for clarity and reproducibility
- Emphasizes following international standards principles, including those set by the World Trade Organization Technical Barriers to Trade (TBT) Committee
Applications
ASTM E1123 is primarily used in the following scenarios:
Naval and Marine Vessel Design
Naval architects and marine engineers rely on these standard practices to evaluate the effectiveness of bulkhead acoustical treatments as they would appear after installation on ships. This supports selection and optimization of sound-insulation materials in compliance with safety and performance criteria.Laboratory Sound Transmission Testing
Testing laboratories utilize ASTM E1123 in conjunction with ASTM E90 to ensure mounting arrangements for tested specimens are consistent and results are representative of the actual application environment.Quality Assurance and Specification
Manufacturers and regulators reference this standard in specifications and contracts to ensure that sound transmission loss data for acoustical materials are obtained using credible and standardized mounting methods.
