5.1 Friction characteristics of traveled surfaces are monitored by skid measurement systems, and the operating procedure for the use of these systems is Test Method E274/E274M. However, dynamic measurement differences between these systems, that comply with the requirements of Test Method...
5.1 When lubricating grease separates oil, the residual material may change in consistency, which can affect the ability of the product to function as designed. Test results obtained with this procedure are not intended to predict oil separation tendencies of grease under dynamic service...
This SAE Aerospace Standard (AS) defines Minimum Performance Standards (MPS), qualification requirements, and minimum documentation requirements for side-facing seats in civil rotorcraft, transport aircraft, and general aviation aircraft. The goal is to achieve comfort, durability, and occupant...
1.1 This test method covers determination of the strength and stress-strain relationships of a cylindrical specimen of either intact, compacted, or remolded cohesive soil. Specimens are subjected to a confining fluid pressure in a triaxial chamber. No drainage of the specimen is permitted during...
1.1 This test method provides a procedure to determine the fatigue life (number of cycles to failure, Nf) of asphalt mixtures, and also the reduction in dynamic modulus (|E*|) with loading cycles, using cylindrical samples subjected to three-point cyclic bending. The results obtained from...
4.1 Samples obtained in accordance with the procedure given in this practice may be used to measure many different properties of a compacted asphalt pavement including, but not limited to: pavement thickness, density, resilient or dynamic modulus, tensile strength, Marshall or Hveem...
1.1 These test methods address the tensile and shear strengths of post-installed and placed-during-construction anchors in masonry test specimens made of masonry assemblies. Environmental exposures include freezing and thawing, moisture, decreased and elevated temperatures and corrosion. These test...
1.1 Many different types of microorganisms (for example, bacteria, fungi, viruses, algae) can occupy indoor spaces. Materials that support microbial growth are potential indoor sources of biocontaminants (for example, spores and toxins) that can become airborne indoor biopollutants. This guide...
1.1 This test method covers the determination of the specific gravity of soil solids by means of a gas pycnometer. Particle size is limited by the dimensions of the test specimen container of the particular pycnometer being used. 1.2 Test Method D854 may be used instead of or in conjunction with...
5.1 The Oxygen Transmission Rate is an important determinant of packaging functionality afforded by packaging materials for a wide variety of packaged products including food, pharmaceuticals and medical devices. In some applications, sufficient oxygen must be allowed to permeate into the package....
1.1 This practice describes procedural steps to create a correlation that can be used to compare results of proppant size distributions between dynamic imaging analyzers (analyzers) and prescribed sieve sets. 1.2 The proppant size and distribution specifications that are included in this...
5.1 The ultrasonic pulse velocity, V, of longitudinal ultrasonic stress waves in a concrete mass is related to its elastic properties and density according to the following relationship: where: E = dynamic modulus of elasticity, μ = dynamic Poisson's ratio, and ? = density. 5.2 This...
4.1 This test method is intended to measure the maximum arrest force and dynamic strength on treestand FAS and components or subsystems. This test is intended for program quality assurance and production quality control purposes. It is not intended to be an independent material or product...
3.1 This test method provides a measure of rheological non-linearity for filled rubber compounds under oscillatory shear conditions: the normalized 3rd harmonic of the torque I3/1. 3.2 Rheological linearity means that the modulus is a function of frequency only. The shear modulus dependency on both...
4.1 The AU method should be considered for vessels that are proven to be free of major flaws or discontinuities as determined by conventional techniques. The AU method may be used for detecting major flaws if other methods are deemed impractical. It is important to use methods such as immersion...
The published SAE J2954 standard established an industry-wide specification that defines acceptable criteria for interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for wireless power transfer (WPT) for light-duty plug-in electric vehicles. This SAE...
1.1 This test method covers the determination of the apparent viscosity of hydrocarbon resins having apparent viscosities up to 2,000,000 millipascal seconds (mPa·s) (Note 1) at temperatures up to 300?°C [572?°F]. Note 1: The SI unit of (dynamic) viscosity is the pascal second. The...
1.1 The purpose of this practice is to specify the procedure for the calibration and verification of elastic torque measurement standards. 1.2 Units-The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are...
1.1 This practice is intended to assist in the selection of sorbents and procedures for the sampling and analysis of ambient (1),2 indoor (2), and workplace (3, 4) atmospheres for a variety of common volatile organic compounds (VOCs). It may also be used for measuring emissions from materials in...
1.1 This practice describes a means for using permeation tubes for dynamically calibrating instruments, analyzers, and analytical procedures used in measuring concentrations of gases or vapors in atmospheres (1, 2).2 1.2 Typical materials that may be sealed in permeation tubes include:...
