Scope

This standard specifies the measurement methods, measurement conditions, measurement devices, and measurement uncertainties for measuring the insertion loss, echo reduction, and sound absorption coefficient of underwater acoustic material samples using the pulse tube method, the free-field method, and the pressure tank near-field method.
This standard applies to the measurement of insertion loss, echo reduction, and sound absorption coefficient of underwater acoustic materials and component samples (hereinafter referred to as "samples"). Among them, the pulse tube method is suitable for measuring small samples, and the free-field method and the pressure tank near-field method are suitable for measuring large samples in different frequency bands.
