Measuring Standards

Instrumentation and control (I&C) equipment ensures the safety, viability, and efficient operation of nuclear power plants by providing accurate and timely measurements of plant control and safety system variables, primarily temperature and pressure. The previously published papers collected in...

5.1 This practice describes a procedure to gather data intended to measure the uniformity of exposure conditions upon test specimens for the fire test methods described in Test Methods E119, E814, E1529, E1725, E1966 and E2336. The collected data from furnaces are intended to form a basis...

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...

Case hardening may be defined as a process for hardening a ferrous material in such a manner that the surface layer, known as the case, is substantially harder than the remaining material, known as the core. The process embraces carburizing, nitriding, carbonitriding, cyaniding, induction, and...

1.1 This fire-test-response standard describes a procedure for measuring the minimum concentration of oxygen, expressed as percent volume, that will just support flaming combustion in a flowing mixture of oxygen and nitrogen. 1.2 This test method provides three testing procedures. Procedure...

This SAE Recommended Practice establishes a test procedure for the evaluation of lane departure warning (LDW), lane keeping assistance (LKA), and lane centering assistance systems used in passenger vehicles and light trucks. This test procedure does not intend to exclude any particular system or...

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...

This specification provides a standard means for testing and measuring the performance characteristics of printed, pressure-sensitive adhesive labels for containers, particularly containers to be used in extreme distribution environments (for example, hazardous materials labels, aerospace,...

1.1 These practices cover procedures for measuring one-, two-, or three-dimensional vector wind components and sonic temperature by means of commercially available sonic anemometer/thermometers that employ the inverse time measurement technique. These practices apply to the measurement of...

The purpose of this SAE Aerospace Recommended Practice (ARP) is to provide a practical definition of external hydraulic fluid leakage exhibited by landing gear shock absorbers/struts. The definition will outline normal (acceptable weepage) and excessive leakage (unacceptable leakage) of shock...

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 This test method is to be used for measuring the vibratory packing density of formed particles that will not break up during sampling, filling, or vibrating of the measuring cylinder under test conditions.

5.1 This test method is used for measuring the vibratory packing density of formed particles used in fixed bed reactors, driers, and so forth.

4.1 The heat of hydration of a calcium aluminate-based castable is liberated over a short period of time (as compared to portland cement). This makes it easy to measure the heat profile using off-the-shelf thermocouple equipment. 4.2 The heat profile can be used to make inferences about the...

1.1 This test method covers the rapid determination of hydraulic activity of slag cement. This test method measures the accelerated strength development of the slag cement by using sodium hydroxide solution as mixing water and curing at elevated temperature. 1.2 The values stated in SI units...

5.1 This test method is part of an overall suite of related test methods that provide repeatable measures of human-system interaction capability including robotic system mobility, dexterity, inspection, remote operator proficiency, and situational awareness. In particular, the operator...

This test method covers determination of the density of freshly mixed concrete and gives formulas for calculating the unit weight, yield or relative yield, cement content, and air content of the concrete. Yield is defined as the volume of concrete produced from a mixture of known quantities of the...

1.1 This practice establishes a procedure for evaluating the life-cycle cost (LCC) of a building or building system and comparing the LCCs of alternative building designs or systems that satisfy the same functional requirements. 1.2 The LCC method measures, in present-value or annual-value...

1.1 This practice covers the procedures for calibration of linear displacement sensors and their corresponding power supply, signal conditioner, and data acquisition systems (linear displacement sensor systems) for use in measuring micromotion. It covers any sensor used to measure...
