New Guide for Test Specimen Preparation for Acoustical Material Testing

1. Scope

This guide covers test specimen preparation for laboratory testing of porous materials used for the absorption and attenuation of sound. Test specimen preparation has a significant effect on the outcome for several standard test methods, including ASTM C384, ASTM C522, ASTM E1050, and ASTM E2611.

Keywords

absorption; acoustical materials; airflow resistance, airflow resistivity; band saw; cutting die; impedance; 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 standard test methods, including ASTM C384, ASTM C522, ASTM E1050, and ASTM E2611.

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