This SAE Recommended Practice describes a laboratory test procedure for measuring the thickness of various resilient insulating padding materials that are used in the automotive industry. Such padding materials may include synthetic or non-synthetic materials, fibrous or cellular materials, high loft or compressed materials, single layer homogeneous or multilayer products, low and high surface density products. Some of these samples may be deformable and elastic, high loft thermal and acoustical fibrous materials, as well. The test method described herein has been developed to establish a means of a uniform procedure for measuring the thickness of different types of samples not only for application to all ground vehicles, but also may be applicable to other situations or conditions. The test method is designed to measure the thickness of flat samples and not formed parts. This test method does not purport to address all of the safety concerns, if any, associated with its use.

This SAE Standard describes a laboratory test procedure for measuring the vibration damping performance of a system consisting of a damping material bonded to a vibrating cantilevered steel bar. The bar is often called the Oberst bar (named after Dr. H. Oberst) and the test method is often called the Oberst bar test method. Materials for damping treatments may include homogeneous materials, nonhomogeneous materials, or a combination of homogeneous, nonhomogeneous, and/or inelastic (such as aluminum foil) materials. These materials are commonly installed in transportation systems such as ground vehicles, marine products, and aircraft to reduce vibration at resonance, and thus reduce the noise radiation from the vibrating surface. The test method described herein was developed to rank order materials for application on panels using general automotive steel but also may be applicable to other situations or conditions.

This SAE Recommended Practice establishes the test procedure, facilities, and instrumentation for determining the noise reduction characteristics of materials commonly installed in ground vehicles, marine, products, and aircraft to reduce noise levels. This document is intended to provide a means of rank ordering materials by utilizing facilities that do not necessarily meet all of the acoustical requirements in ASTM E 90, Laboratory Measurements of Airborne Sound Transmission Loss of Building Partitions. Latitude is permitted in certain test conditions to allow better correlation with in-use acoustical results.

This test method is applicable for determining the relative compression and recovery of fibrous insulation padding materials.

This SAE Recommended Practice describes a laboratory test procedure for measuring the random incidence sound absorption performance of a material or a part in a small size reverberation room by measuring decay rates. The absorption performance may include sound absorption coefficient of the test sample and or the amount of energy absorbed by the test sample. Materials for absorption treatments may include homogeneous materials, nonhomogeneous materials, or a combination of homogeneous, nonhomogeneous, and/or inelastic impervious materials. These materials are commonly installed in the mobility products and in the transportation systems such as ground vehicles, marine products, aircraft, and commercial industry (in industrial and consumer products) to reduce reverberant sound build-up and thus reduce the noise level in the environment by minimizing reflections off of hard surfaces.
