This specification covers crosslinked polymer insulation material consisting substantially of polyethylene or a polyethylene copolymer for electrical wires and cables in conductor, suitable for continuous use on power cables in wet and dry locations, having specified sizes and operating at...
4.1 As determined by this test method, the pipe insulation lineal thermal resistance or conductance (and, when applicable, the thermal resistivity or conductivity) are means of comparing insulations which include the effects of the insulation and its fit upon the pipe, circumferential and...
5.1 This practice is intended to provide standardized procedures for evaluating linear phased-array ultrasonic probes. It is not intended to define performance and acceptance criteria, but rather to provide data from which such criteria may be established. 5.2 Implementation may require more...
This specification establishes the performance requirements for surge suppressors used on shipboard ac power circuits that may consist of a single circuit element or may be a hybrid device using several suppression devices. The surge suppressor shall be a protective device for limiting voltage...
1.1 These test methods cover procedures for evaluating the characteristics of forced-convection ventilated electrically-heated ovens, operating over all or part of the temperature range from 20?°C above the ambient temperature to 500?°C and used for thermal endurance evaluation of electrical...
1.1 This test method covers procedures for evaluating the interaction of electrical insulation components used, or intended to be used, in electrical insulation systems. 1.2 This test method is useful for determining compatibility but additional testing will potentially be required for some...
4.1 This guide suggests techniques to evaluate intermittences in a contact pair while it is subjected to simulated or actual environmental stress. Such measurements are a valuable tool in predicting circuit performance under these stress conditions and in diagnosing observed problems in circuit...
1.1 This practice applies to techniques that use nondestructive electrical impedance (EI) scanners to locate moisture and evaluate the comparative moisture content within insulated low-slope roofing and waterproofing systems. 1.2 This practice is applicable to roofing and waterproofing systems...
4.1 This practice is intended to help users, particularly power plant operators, maintain effective control over their mineral lubricating oils and lubrication monitoring program. This practice may be used to perform oil changes based on oil condition and test results rather than on the basis of...
1.1 This practice applies to techniques that use nondestructive electrical impedance (EI) scanners to locate moisture and evaluate the comparative moisture content within insulated low-slope roofing and waterproofing systems. 1.2 This practice is applicable to roofing and waterproofing systems...
5.1 This test method is useful in research and quality control for evaluating insulating materials and systems since they provide for the measurement of the endurance used to compare different materials to the action of corona on the external surfaces. A poor result on this test does not indicate...
1.1 This specification addresses the minimum performance for flexible laminate protective jacket and a pressure sensitive adhesive tape for use over thermal insulation on pipes, duct, and equipment operating at both above and below ambient temperatures and installed outdoors, above ground....
4.1 The high-voltage, low-current type of arc resistance test is intended to simulate only approximately such service conditions as exist in alternating current circuits operating at high voltage, but at currents limited to units and tens of milliamperes. 4.2 In order to distinguish more...
1.1 These test methods cover procedures for evaluating the characteristics of forced-convection ventilated electrically-heated ovens, operating over all or part of the temperature range from 20?°C above the ambient temperature to 500?°C and used for thermal endurance evaluation of electrical...
5.1 Tensile-impact energy is the energy required to break a standard tension-impact specimen in tension by a single swing of a standard calibrated pendulum under a set of standard conditions (see Note 2). To compensate for the minor differences in cross-sectional area of the specimens, the energy...
5.1 Electrical equipment has the potential to fail as a result of electrical tracking of insulating material that is exposed to various contaminating environments and surface conditions. A number of ASTM and other tests have been designed to quantify behavior of materials, especially at relatively...
5.1 Subject to the limitations listed in 1.3, this practice can be used as a research tool to optimize spray equipment and paint formulations, as well as to study the relative effect on transfer efficiency of changing operating variables, spray application equipment, type of coatings, etc.
5.1 This test method is useful in determining the thermal endurance characteristics and thermal indices of film-insulated round magnet wire in air (see 1.3). This test method is used as a screening test before making tests of more complex systems or functional evaluation. It is also used where...
5.1 PCRT Applications and Capabilities-PCRT has been applied successfully to a wide range of outlier screening applications in the manufacture and maintenance of metallic and non-metallic parts. Examples of anomalies detected are discussed in 1.1. PCRT has been shown to provide cost effective and...
4.1 Design calculations for such components as transmission lines, antennas, radomes, resonators, phase shifters, etc., require knowledge of values of complex permittivity at operating frequencies. The related microwave measurements substitute distributed field techniques for low-frequency...
