This SAE Standard measures the percent thermal efficiency of materials in sleeve form used to contain heat or insulate around a hot component. The percent thermal efficiency (%TE) is determined by measuring the power difference expended by the heat source (cartridge heater) with and without the test sleeve at the specified temperature. See SAE J2302 to measure radiant heat flow of sleeves.

This SAE Recommended Practice describes a method of determining the relative flexibility of padding and/or acoustical composites.

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 procedure measures the resistance to radiant heat flow of insulating materials in sleeve form. The sleeve’s effectiveness (SE) is determined by measuring the difference in surface temperature of a flat black, single-diameter ceramic cylinder with and without the standard diameter sleeve at the specified temperature, position, and distance from the radiant heat source.

SAE developed this document and associated spreadsheets at the request of automobile manufacturers to help compare products from multiple suppliers using standard data presentation formats. This document includes several preferred formats for presenting acoustical data on materials, components, systems, or vehicles. These formats cover the range of acoustical tests commonly conducted in the automotive industry. These tests follow SAE and ASTM test practices as well as vehicle specific test methods. For each test, the details of samples and test conditions can be entered into an applicable electronic spreadsheet together with the acoustical results data. These data are then linked to standard graphical display(s) for each test. All manufacturers and suppliers in this industry are encouraged to present data and results in these formats.

This SAE Recommended Practice 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 presents a test procedure for determining the airborne sound insulation performance of materials and composite layers of materials commonly found in mobility, industrial and commercial products under conditions of representative size and sound incidence so as to allow better correlation with in-use sound insulator performance. The frequency range of interest is typically 125 to 8000 Hz 1/3 octave band center frequencies. This test method is designed for testing flat samples, although in some applications the methodology can be extended to evaluate formed parts, pass-throughs, or other assemblies to determine their acoustical properties. For non-flat parts or assemblies where transmitted sound varies strongly across the test sample surface, a more appropriate methodology would be ASTM E90 (with a reverberant receiving chamber) or ASTM E 2249 (intensity method with an anechoic or hemi-anechoic receiving chamber).
