New Guide for Standard Guide for Test Specimen Preparation for Acoustical Material Testing

1. Scope

Test specimen preparation has a significant effect on the outcome of several acoustical material Test Methods, including C384, C522, E1050, and E2611. The mounting conditions of the test specimen for these test methods require that a seal is created when the material is mounted into the test apparatus.

Keywords

absorption; acoustical materials; airflow resistance; band saw; cutting die; impedance tube; lathe; normal incidence; transmission loss; water cutting machine

Rationale

A standard guide for test specimen preparation for acoustical material testing should improve within- and between-laboratory precision for several existing Test Methods, including C384, C522, E1050, and E2611 by providing the user of these Test Methods with a more uniform and repeatable approach to preparing small disc-shaped test specimens

The title and scope are in draft form and are under development within this ASTM Committee.
