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 Technical Information Report (TIR) provides test methods for evaluating hydrogen sensors when the hydrogen system integrator and/or vehicle manufacturer elect to use such devices on board their hydrogen vehicles, including hydrogen fuel cell electric vehicles (FCEV). The tests described in 5.1 of this document are performance-based and were developed to assess hydrogen sensor metrological parameters. These tests were designed to accommodate a wide range of environmental and operating conditions based on different possible situations and sensor implementations within the vehicle. Section 5.2 covers supplemental electrical safety and physical stress tests. These are based upon standard tests developed for qualifying electrical and other components for use on vehicles and do not explicitly pertain to gas sensor metrological performance assessment.
This standard is applicable to the engineering or the reengineering of: a. Commercial or non-commercial systems, or portions thereof; b. Any system, small or large, simple or complex, software-intensive or not, precedented or unprecedented; c. Systems made up of hardware, software, firmware, personnel, facilities, data, materials, services, techniques, or processes (or combinations thereof); d. A new system or a legacy system, or portions thereof. NOTE: The specific tasks and implementation methods for applying the processes required by this standard can vary, for example, between commercial and government projects, or between customer-involved and internally developed projects. The fundamental processes, however, are the same in all cases. The requirements of this standard, or a designated subset, are intended to be applied by projects establishing policies and procedures for project implementation of the adopted process and process elements of this standard.
This SAE Recommended Practice provides the method to assign numerical values of brake effectiveness, using data from single station inertia dynamometer effectiveness tests, and to identify a uniform procedure to mark these values on the edge of brake blocks in excess of 12.7 mm (0.51 in) in thickness. The edge markings are intended to provide relevant and meaningful data on the normal and hot effectiveness of brake blocks, using the reference full size brake assembly, to aid in the characterization of these brake block frictional properties. This edge marking methodology is intended to permit accurate identification of the effectiveness values over the full wear life of the brake block. This is accomplished by means of permanent markings on one edge of the brake block.
This specification covers a butadiene-acrylonitrile (NBR) rubber in the form of molded rings. These rings have been used typically as sealing rings in contact with diester synthetic lubricants in service up 150 degrees C (302 degrees F), but usage is not limited to such applications. The cross-section of such rings is usually not over 0.275 inch (6.98 mm) in diameter or thickness.
This specification covers a high temperature, compression set and fluid resistant fluorocarbon (FKM) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes for aeronautical and aerospace applications.
This specification covers a fluorocarbon (FKM) rubber in the form of O-rings, O-ring cord, compression seals, and molded-in-place gaskets for aeronautical and aerospace applications. These products have been used typically as sealing rings, compression seals, O-ring cord, and molded-in-place gaskets in contact with air and a wide variety of fuels, lubricants, and specific hydraulic fluids but usage is not limited to such applications. Each application should be considered individually. This class of fluoroelastomers is not recommended for use in high temperature stabilized, “HTS”, engine oils. Each “HTS” oil should be evaluated separately. This fluorocarbon rubber has a typical service temperature range of -20 to +400 °F (-29 to +204 °C) in air.
This SAE Recommended Practice provides the test procedure and methods to calculate the effectiveness of brake blocks, using an inertia dynamometer. To minimize testing variability, and to optimize standardization and correlation, a single, high volume size of brake block is specified (FMSI No. 4515E) and evaluated in a reference S-cam brake assembly of 419 mm x 178 mm (16.5 in x 7.0 in) size, using a specified brake drum.
The scope of the Quality Program Guidelines, in the format of a checklist, is to help ensure compliance with the current documents as listed in §2 "Applicable Documents " that meet Airline Operator's and regulatory requirements. It is the responsibility of all other personnel that performs the deicing/anti-icing task to adhere to these requirements.
