Mechanical and Material Requirements for Steel Nuts

2017-07-20
CURRENT
J995_201707
This SAE Standard covers the mechanical and material requirements for three grades of steel nuts suitable for use in automotive and related engineering applications, in sizes 1/4 to 1-1/2 inches, inclusive, and with dimensions conforming with the requirements of the latest issue of SAE J482 or ASME B18.2.2, except for machine screw nuts which are not covered in this standard. This document does not include limits for surface discontinuities. Where usage requires such control, limits may be specified separately. For sizes 1/4 through 1 inch, this may be done by the statement: “Surface discontinuities shall not exceed the limits specified in ASTM F812/F812M.”

Brake Lining, Rotor and Drum Wear Measurements

2017-07-18
WIP
J2986
This Recommended Practice provides a common method to measure wear of friction materials (brake pad assemblies and brake shoes) and their mating part (brake rotor or brake drum). These wear measurements apply to brakes fitted on passenger cars and light trucks up to 4,540 kg of Gross Vehicle Weight Rating or vehicles category M1 on the European Community.

Dynamometer Low-Frequency Brake Noise Test Procedure

2017-07-18
WIP
J3002
This procedure will outline the necessary test equipment (fixturing, dynamometer, data acquisition system, etc.) and test sequence required to test for low-frequency brake noise on a brake noise dynamometer. It is intended to complement SAEJ2521, which focuses on high-frequency brake squeal.

Laboratory Measurement of the Airborne Sound Barrier Performance of Flat Materials and Assemblies

2017-07-13
CURRENT
J1400_201707
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 100 to 8000 Hz 1/3 octave-band center frequencies. This test method is designed for testing flat samples with uniform cross section, 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 E2249 (intensity method with an anechoic or hemi-anechoic receiving chamber).

Test Procedures for Automotive Structural Composite Materials

2017-07-12
CURRENT
J2253_201707
This SAE Standard is intended to serve as a guide for the collection of physical, mechanical, and thermal properties of fiber-reinforced polymer composite materials for automotive structural applications. This document attempts to utilize test methods applicable to the widest range of structural materials and processes without compromising the integrity of the data being sought. A summary of the material characterization is shown in Section 15.

Battery Electric Vehicle Energy Consumption and Range Test Procedure

2017-07-12
CURRENT
J1634_201707
This SAE Recommended Practice establishes uniform procedures for testing Battery Electric Vehicles (BEVs) which are capable of being operated on public and private roads. The procedure applies only to vehicles using batteries as their sole source of power. It is the intent of this document to provide standard tests which will allow for the determination of energy consumption and range for light-duty vehicles (LDVs) based on the Federal Emission Test Procedure (FTP) using the Urban Dynamometer Driving Schedule (UDDS) and the Highway Fuel Economy Driving Schedule (HFEDS), and provide a flexible testing methodology that is capable of accommodating additional test cycles as needed. Realistic alternatives should be allowed for new technology. Evaluations are based on the total vehicle system's performance and not on subsystems apart from the vehicle. NOTE: The range and energy consumption values specified in this document are the raw, test-derived values.
