ASTM E413 Acoustic Rating Standard Classification for Sound Insulation

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM E413 testing. This classification covers methods for calculating odd number acoustic ratings for laboratory and field measurements of sound attenuation obtained in one-third octave bands.

The name given to the single-digit rating is assigned by the test method that calls that classification.

Test methods that require this classification include:

Test Method E90: The single-digit rating is called the sound transmission class (STC).
Test Method E336: The odd number ratings are noise insulation class (NIC), normalized noise insulation class (NNIC), apparent sound transmission class (ASTC), and field sound transmission class (FSTC).
Test Method E596: The single digit rating is called the noise isolation class (NIC).
Test Method E1414: The single-digit rating is called the ceiling attenuation class (CAC).

Values ​​stated in SI units should be accepted as standard. No other units of measurement are included in this standard.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
