Acoustics--Measurement of Airborne Noise Emitted By Earthmoving Machinery--OperatorS Position--Stationary Testing Condition

1991-06-01
J2103_199106
This SAE Standard describes a method for determining the noise emitted by earthmoving machinery at the operator's position in terms of the equivalent continuous A-weighted sound pressure level while the machine is in a stationary test condition. This SAE Standard is a special test code for specific types of earthmoving machinery. It is an extension of ISO 6081 which contains the general requirements for many types of machinery and equipment. Specific requirements are provided in this special test code to enable the sound pressure level at the operator's position, with the machine in a stationary test condition, to be determined in a manner which is repeatable. Attachments (bucket, dozer, etc.) for the manufacturer's production version shall be fitted since this is the configuration most likely to exist when the machine is in actual use. This document will enable compliance with noise limits to be determined.

HISTORICAL
J428B_197805
The scope of this SAE Information Report is to provide basic information on ultrasonics, as applied in the field of nondestructive inspection. References to detailed information are listed in Section 2. Ultrasonic testing is a versatile nondestructive inspection method which is applicable to most solid materials, metallic or nonmetallic. Materials inspected include steel, aluminum, cast iron, concrete, rubber, glass, and plastics. Through these tests, surface and internal discontinuities such as laps, seams, voids, cracks, blow holes, inclusions, lack of bond, and porosity can be detected. Material thickness can be accurately measured from one side. Under certain conditions, materials at elevated temperatures can be inspected.

Acoustics--Measurement of Exterior Noise Emitted By Earthmoving Machinery--Dynamic Test Conditions

1991-06-01
J2104_199106
This SAE Standard describes a method for determining the noise emitted to the environment by earthmoving machinery in terms of the A-weighted sound power level while the machine is working under dynamic test conditions. This SAE Standard is special test code for specific types of earthmoving machinery. It is an extension of SAE J2101/ISO 4872, which contains the general requirements for construction equipment. A simulated dynamic rath than an actual work cycle test condition is chosen. Dynamic test conditions provide acceptable noise emission data, which are repeatable and representative. Actual work cycle tests are complex and repeatability can be a problem Specific procedures are described in this document to enable the sound power emission in dynamic test conditions to be determined in a manner that is repeatable.

This SAE Standard describes a method for determining the noise emitted by earthmoving machinery at the operator's position in terms of the equivalent continuous A-weighted sound pressure level while the machine is carrying out a simulated work cycle. This SAE standard is a special test code for specific types of earthmoving machinery. It is an extension of ISO 6081 which contains the general requirements for many types of machinery and equipment. A simulated rather than an actual work cycle test condition is chosen. Simulated work cycles provide acceptable noise emission data which are repeatable and representative.

Acoustics--Measurement of Airborne Noise Emitted By Earthmoving Machinery--Method for Determining Compliance With Limits for Exterior Noise--Stationary Test Condition

1991-06-01
J2102_199106
This SAE Standard describes a method for determining the exterior noise emitted by earthmoving machinery in terms of the A-weighted sound power level while the machine is in a stationary test condition. At six positions on a hemispherical surface, the equivalent continuous A-weighted sound pressure levels are measured. The A-weighted sound power level of the machinery is calculated from the measured values.

J2629_201508
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.

Laboratory Measurement of the Acoustical Performance of Body Cavity Filler Materials

2010-05-26
HISTORICAL
J2846_201005
This SAE Recommended Practice describes a laboratory test procedure for measuring the acoustical performance of a system consisting of a body cavity filler material formed into a rectangular cross-section channel. Materials for this test may include both heat reactive and chemically reactive products, with or without a shelf to simulate a baffle in an application, or a combination of body cavity filler and aluminum foil to enhance the performance. These materials are commonly installed in transportation systems such as ground vehicles, and thus reduce the noise propagation through the rails, rockers, and pillar/posts. This document is intended to rank order the acoustical performance of materials for application on channels using general automotive steel, such that the effects of sealing of pinch welds in addition to the material could be easily evaluated.
