1.1 This practice covers the mathematical processing of longitudinal profile measurements to produce a wheelchair pathway roughness statistic called the Wheelchair Pathway Roughness Index (WPRI). 1.2 This provides a standard practice for computing and reporting an estimate of pathway...
5.1 Method A-Low voltage holiday detection is used to locate holidays and pinholes in thin-film coatings (up to 0.508?mm (20?mils) using a sponge wetted with tap water (and a wetting agent for coatings thicker than 10?mils). The water carries the current from the electrode through the holiday to...
1.1 This specification covers the general requirements for the 315/70R22.5 154/150L radial truck standard reference test tire. The tire covered by this specification is primarily for use as a reference tire for braking traction, snow traction, and wear performance evaluations, but may also be used...
1.1 This specification covers the general requirements for the 245/70R19.5 136/134M radial truck standard reference test tire. The tire covered by this specification is primarily for use as a reference tire for braking traction, snow traction, and wear performance evaluations, but may also be used...
1.1 This specification covers the general requirements for the P225/60R16 97S radial standard reference test tire. The tire covered by this specification is primarily for use as a reference tire for braking traction, snow traction, and wear performance evaluations, but may also be used for other...
1.1 This practice describes equipment and procedures for the calibration of systems used for measuring vehicular response to pavement roughness. Such systems are referred to as response-type systems. (See Test Method E1082.) 1.2 The response-type system includes the driven vehicle, the...
3.1 The surface roughness of PM parts is an important characteristic in relation to factors such as their load-bearing, wear, sealing, sliding, adhesion, electrical contact, and lubricant retention properties. 3.2 Surface roughness may also be critical for component assembly or system...
4.1 The PCI is a numerical indicator that rates the surface condition of the pavement. The PCI provides a measure of the present condition of the pavement based on the distress observed on the surface of the pavement, which also indicates the structural integrity and surface operational condition...
4.1 These practices provide a means for evaluating traveled surface-roughness characteristics directly from a measured profile. The calculated values represent vehicular response to traveled surface roughness. 4.2 These practices provide a means of calibrating response-type...
1.1 This terminology covers definitions for approved standards under the jurisdiction of ASTM Committee E17 on Vehicle-Pavement Systems. Definitions of terms specific to an individual standard are listed in the appendix. For additional information, see Terminology D8, Terminology F538, Special...
This specification covers grades of seamless, welded, and heavily cold worked austenitic and ferritic/austenitic stainless steel sanitary tubing. Seamless tubes shall be manufactured by a process that does not involve welding at any stage. Welded tubes shall be made using an automated welding...
This practice covers the acceptance criteria for surface inspection of investment castings through visual examination. The material shall conform to Levels II, III, and IV acceptance criteria for features of surface pits, positive metal, parting line and ejector pin marks, gate height, and surface...
This test method covers the procedures for the standard practice of performing ultrasonic shear and longitudinal wave examinations on turbine-generator steel retaining rings. A pulsed reflection-type ultrasonic instrument shall be used for the tests. Scanning of steel specimens may be performed by...
5.1 General: 5.1.1 This guide is intended to support PBF-LB process and parameter development, part acceptance criteria, and process control tests. 5.1.2 Flaws and Defects-Fabricating fully dense parts continues to be a challenge in AM as the process intrinsically introduces volumetric flaws into a...
1.1 These practices cover the calculation of truck response to longitudinal profiles of traveled surface roughness. 1.2 These practices utilize computer simulations to obtain two truck responses including: sprung and unsprung mass vertical displacement, velocity, and acceleration; and sprung...
This SAE Standard is concerned with the geometrical irregularities of surfaces of solid materials. It established definite classifications for various degrees of roughness and waviness and for several varieties of lay. It also provides a set of symbols for use on drawings and in...
4.1 The PCI is a numerical indicator that rates the surface condition of the pavement. The PCI provides a measure of the present condition of the pavement based on the distress observed on the surface of the pavement, which also indicates the structural integrity and surface operational condition...
4.1 The CTAB molecule is relatively large; so it is not adsorbed in micropores or on surface roughness. Thus, the CTAB surface area reflects only the surface of the silica that is available for interaction with rubber molecules.
This specification covers structural clay nonloadbearing tile (partition, fireproofing, and furring). One grade of tile is covered, Grade NB. Structural clay non-load-bearing tile shall conform to the specified requirements for absorption. Tile intended for use in fireproofing structural members...
1.1 This standard is device independent. Measurements may be made by any device capable of producing a suitable longitudinal elevation profile for the vehicular traveled surface. However, cellular phone-based road rating devices are not applicable. The vehicle-based profiling device, commonly...
