This recommended practice defines methods for the measurement of periodic, random and transient whole-body vibration. It indicates the principal factors that combine to determine the degree to which a vibration exposure will cause discomfort. Informative appendices indicate the current state of knowledge and provide guidance on the possible effects of motion and vibration on discomfort. The frequency range considered is 0.5 Hz to 80 Hz. This recommended practice also defines the principles of preferred methods of mounting transducers for determining human exposure. This recommended practice is applicable to light passenger vehicles (e.g., passenger cars and light trucks). This recommended practice is applicable to motions transmitted to the human body as a whole through the buttocks, back and feet of a seated occupant, as well as through the hands of a driver. This recommended practice offers a method for developing a ride performance index but does not specifically describe how to

This standard applies to all products and services produced for Aeronautics and Space enterprises and regulatory environments, including those produced by component facilities and technical and service support centers. If applied, this standard must be cited in the CM requirements of Enterprise Planning, Facilities Programs, Projects, and Supplier agreements. This standard applies throughout all phases of the program and project life cycle. CM is about the truth, trust, and traceability of products, data used to produce products, and processes throughout their life cycle and should be applied across the Enterprise at the process and product level. The significant data to which CM is applied includes scientific and engineering data; data that drives mission success; data that ensures IT security; and data used to make technical, programmatic, and business decisions. Proper application of CM is essential for product integrity and overall effectiveness. Acquirers complying with the

The scope of this SAE Information Report is limited to a lift crane mounted on a fixed or floating platform, lifting loads from a vessel alongside. The size of the vessel is assumed not to exceed that of a workboat as defined in 3.15.
The scope of this SAE Recommended Practice is limited to cranes mounted on a fixed platform lifting loads from a vessel alongside. The size of the vessel is assumed not to exceed that of a work boat as defined in 3.14.
This SAE Recommended Practice establishes the method to determine Sound Level of a snowmobile under typical trail operating conditions. Snowmobiles have different engine power levels that depends on the model.
This SAE Recommended Practice establishes uniform test procedures and performance requirements for engine coolant type heating systems of enclosed truck cabs. The intent is to provide a test that will ensure acceptable comfort for cab occupants. It is limited to a test that can be conducted on uniform test equipment in commercially available laboratory facilities. There are two options for producing hot coolant in this document. Testing using these two approaches on the same vehicle will not necessarily provide identical results. Many vehicle models are offered with optional engines, and each engine has varying coolant temperatures and flow rates. If the test is being conducted to compare the performance of one heater design to another heater design, then the external coolant source approach (Test A) will yield the most comparable results. If the test is being conducted to validate the heater installation on a specific vehicle model with a specific engine, then using the engine to heat

This SAE Recommended Practice is intended for stakeholders of the automotive industry that are conducting emission testing on materials, parts, or components used in automotive interiors. Testing methods may specifically define the handling and packaging conditions for the material to be analyzed. In these cases, follow the method as closely as possible. Use this document as a guide where the protocol for handling and packaging the samples between production and testing may be undefined or ambiguous.
This SAE Recommended Practice is intended for use in testing and evaluating the approximate performance of engine-driven cooling fans. This performance would include flow, pressure, and power. This flow and pressure information is used to estimate the engine cooling performance. This power consumption is used to estimate net engine power per SAE J1349. The procedure also provides a general description of equipment necessary to measure the approximate fan performance. The test conditions in the procedure generally will not match those of the installation for which cooling and fuel consumption information is desired. The performance of a given fan depends on the geometric details of the installation, including the shroud and its clearance. These details should be duplicated in the test setup if accurate performance measurement is expected. The performance at a given air density and speed also depends on the volumetric flow rate, or the pressure rise across the fan, since these two
