Measurement Standards

This latest edition of the Procedural Standards for Measurement is entirely rewritten and focuses on the measurement and reporting techniques for obtaining sound and vibration data that a NEBB contractor and other professionals in the heating, ventilating, and air conditioning (HVAC)...

This book describes how modern technology can be used to improve units of measurement. It paints a picture of a dynamic and changing universe, one in which systems can be integrated with improved measurement practices. It looks beyond the static nature of everyday objects to an...

Thrust measurement systems come in many sizes and shapes, with varying degrees of complexity, accuracy and cost . For the purposes of this information report, the discussions of thrust measurement will be limited to axial thrust in single-axis test systems.

This recommended practice establishes test procedures and best practices for PM measurements under partial flow conditions. PFDS PM testing and certification is primarily used in heavy duty applications as described in 40 CFR Part 1065 because full flow sampling systems with a dilution...

This SAE Recommended Practice describes a laboratory test procedure for measuring the composite loss factor and bending stiffness properties of a system consisting of a damping material bonded to a vibrating bar which is excited at the center. The bar could be a steel, aluminum, glass, or other...

This SAE Recommended Practice establishes the test procedure, environment, and instrumentation to be used for measuring the exterior exhaust sound level for passenger cars, multipurpose vehicles, and light trucks under stationary conditions providing a continuous measure of exhaust system or...

This SAE Standard is equivalent to ISO Standard 362 - 1997 except for the differences detailed in Appendix A , and includes the modifications adopted by WP 29 in ECE R51 Revision 1 and EEC 92/97 and EEC 96/20. This document specifies an engineering method for measuring the noise emitted by...

This procedure is applicable to modes from 500 and 13,000 Hz. The parameters measured with this procedure are defined as the damping factor, ξ for first nine vibration modes of the beam. The measurement will be done in free-free conditions and with temperature.

5.1 As AFM measurement technology has matured and proliferated, the technique has been widely adopted by the nanotechnology research and development community to the extent that it is now considered an indispensible tool for visualizing and quantifying structures on the nanoscale. Whether...

5.1 This practice is used to provide steel phase transformation data required for use in numerical models for the prediction of microstructures, properties, and distortion during steel manufacturing, forging, casting, heat treatment, and welding. Alternatively, the practice provides end users of...

This Aerospace Recommended Practice (ARP) describes a standard method and means for measuring or calibrating the "Spectrum Amplitude" output of an impulse generator.

5.1 The health of workers in many industries is at risk through exposure by inhalation to toxic metals. Industrial hygienists and other public health professionals need to determine the effectiveness of measures taken to control workers' exposures, and this is generally achieved by making workplace...

This SAE Standard 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...

1.1 This is a compilation of only those terms and corresponding definitions included in or being considered for inclusion in ASTM documents relating to thermophysical properties. It is not intended as an all-inclusive listing of thermophysical property terms. Terms that are generally understood or...
