Standard Test Method for Measurement of Thickness of Metallic Coatings by Measurement of Cross Section with a Scanning Electron Microscope
Abstract: 4.1 This test method is useful for the direct measurement of the thicknesses of metallic coatings and of individual layers of composite coatings, particularly for layers thinner than normally measured with the light ... -
Standard Test Method for Porosity in Gold Coatings on Metal Substrates by Nitric Acid Vapor
Abstract: 5.1 Gold coatings are often specified for the contacts of separable electrical connectors and other devices. Electrodeposits are the form of gold that is most used on contacts, although it is also employed as clad metal ... -
Standard Test Method for Measurement of Internal Stress of Plated Metallic Coatings with the Spiral Contractometer
Abstract: 5.1 The spiral contractometer, properly used, will give reproducible results (see 9.5) over a wide range of stress values. Internal stress limits with this method can be specified for use by both the purchaser and the ... -
Standard Guide for Selection of Sampling Plans for Inspection of Electrodeposited Metallic and Inorganic Coatings
Abstract: This guide covers the standard method for selecting sampling plans to be used in the inspection of electrodeposited metallic and inorganic coatings on products for the purpose of deciding whether submitted lots comply with ... -
Standard Specification for Silver-Nickel Electrical Contact Materials
Abstract: 9.1 Proprietary methods for manufacture of these materials vary significantly among suppliers and these methods influence such properties as arc erosion, contact resistance, and the tendency to weld in service. Since the ... -
Standard Practice for Measuring Electrical Contact Noise in Sliding Electrical Contacts
Abstract: 3.1 Resistance or voltage values alone do not provide sufficient detail for an engineering evaluation of contact noise. This practice lists the test conditions that should be reported with noise measurements and indicates ... -
Standard Guide for Corrosion Monitoring in Laboratories and Plants with Coupled Multielectrode Array Sensor Method
Abstract: 4.1 Guide G96 describes a linear-polarization method and an electrical resistance method for online monitoring of corrosion in plant equipment without the need to enter the system physically to withdraw coupons. These two ... -
Standard Guide for Evaluating Uncertainty in Calibration and Field Measurements of Broadband Irradiance with Pyranometers and Pyrheliometers
Abstract: 5.1 The uncertainty in outdoor solar irradiance measurement has a significant impact on weathering and durability and the service lifetime of materials systems. Accurate solar irradiance measurement with known uncertainty ... -
Standard Specification for Nickel-Iron-Chromium-Silicon Alloys (UNS N08330 and N08332) Seamless Pipe and Tube
Abstract: This specification covers alloys UNS N08330 and N08332 in the form of hot-finished and cold-finished seamless pipe and tube intended for heat resisting applications and general corrosive service. The material shall be ... -
Standard Specification for Compact Round Concentric-Lay-Stranded Copper Conductors
Abstract: This specification covers bare compact round concentric-lay-stranded conductors made from uncoated round copper wires for general use for electrical purposes. Welds and brazes shall be made in rods and wires prior to final ... -
Standard Specification for Palladium-Silver-Copper Electrical Contact Alloy
Abstract: This specification covers an alloy containing palladium, silver, copper, platinum, and nickel in the form of wire, rod, and strip for electrical contacts. The materials shall be processed by cold working, heat treating, ... -
Standard Practice for Detecting mu-phase in Wrought Nickel-Rich, Chromium, Molybdenum-Bearing Alloys
Abstract: 4.1 These test methods describe laboratory tests to determine the presence of mu-phase in Wrought Nickel-Rich, Chromium, and Molybdenum-Bearing Alloys through comparison of microstructure observed for etched metallographic ... -
Standard Guide for Preparation of Magnesium and Magnesium Alloys for Electroplating
Abstract: 3.1 Metals are electroplated on magnesium for various purposes: solderability, RF grounding, hermetic sealing, wear resistance, corrosion resistance, appearance, and electrical conductivity, for example. Because magnesium ... -
Standard Practice for Determining the Activation Spectrum of a Material (Wavelength Sensitivity to an Exposure Source) Using the Sharp Cut-On Filter or Spectrographic Technique
Abstract: 4.1 The activation spectrum identifies the spectral region(s) of the specific exposure source used that may be primarily responsible for changes in appearance and/or physical properties of the material. 4.2 The spectrographic ... -
Standard Test Method for Alternating Current Magnetic Properties of Materials Using the Wattmeter-Ammeter-Voltmeter Method, 100 to 10 000 Hz and 25-cm Epstein Frame
Abstract: 4.1 This test method evaluates the performance of flat-rolled magnetic materials over a wide frequency range of ac excitation with and without incremental dc bias, as used on transformers, motors, and other laminated core ... -
Standard Guide for Application of Basic Statistical Methods to Weathering Tests
Abstract: 4.1 The correct use of statistics as part of a weathering program can greatly increase the usefulness of results. A basic understanding of statistics is required for the study of weathering performance data. Proper ... -
Standard Test Method for Calibration of a Pyranometer Using a Pyrheliometer
Abstract: 4.1 The pyranometer is a radiometer designed to measure the sum of directly solar radiation and sky radiation in such proportions as solar altitude, atmospheric conditions and cloud cover may produce. When tilted to the ... -
