Standard Test Method for Porosity in Metallic Coatings by Humid Sulfur Vapor (“Flowers-of-Sulfur”)
Abstract: 5.1 A major use of this test procedure is for determining coating quality. Porosity tests are indications of the completeness of protection or coverage offered by the coatings, since the coatings described in 1.2 are ... -
Standard Test Method for Porosity in Gold and Palladium Coatings by Sulfurous Acid/Sulfur-Dioxide 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 inlay or clad ... -
Standard Test Method for Shear Testing of Aluminum Alloys
Abstract: 5.1 The intent of this method is to provide a means of measuring the shear strength of aluminum-alloy wrought and cast products. Data obtained by this method are used to calculate minimum properties that can be utilized ... -
Standard Practice for Determining Rail-to-Earth Resistance
Abstract: 4.1 Low resistance between the rails and earth could result in large magnitudes of stray earth currents with the attendant corrosion damage to underground metallic structures. 4.2 These measurements are of a low voltage ... -
Standard Test Method for Determination of the Breakaway Friction Characteristics of Rolling Element Bearings
Abstract: 5.1 This test is a simple, effective way of determining the ability of bearings to roll freely. Most bearing manufacturers do not supply information on the breakaway friction coefficient of their products and if this is a ... -
Standard Test Method for Using Atmospheric Pressure Rotating Cage
Abstract: 3.1 The rotating cage (RC) test system is relatively inexpensive and uses simple flat specimens that allow replicates to be run with each setup (1-11).3 3.2 The RC method can be used to evaluate either corrosion inhibitors, ... -
Standard Test Method for Determining Ignition Sensitivity of Materials to Mechanical Impact in Ambient Liquid Oxygen and Pressurized Liquid and Gaseous Oxygen Environments
Abstract: 5.1 This test method evaluates the relative sensitivity of materials to mechanical impact in ambient pressure liquid oxygen, pressurized liquid oxygen, and pressurized gaseous oxygen. 5.2 Any change or variation in test ... -
Standard Practice for Characterization of Atmospheric Test Sites
Abstract: 4.1 This practice gives suggested procedures for characterization of atmospheric test sites. It can be useful to researchers, manufacturers, engineering firms, architects, and construction contractors to provide corrosion ... -
Standard Guide for Crevice Corrosion Testing of Iron-Base and Nickel-Base Stainless Alloys in Seawater and Other Chloride-Containing Aqueous Environments
Abstract: 4.1 This guide covers procedures for crevice-corrosion testing of iron-base and nickel-base stainless alloys in seawater. The guidance provided may also be applicable to crevice corrosion testing in other chloride containing ... -
Standard Practice for Conducting Atmospheric Corrosion Tests on Metals
Abstract: 3.1 The procedures described herein can be used to evaluate the corrosion resistance of metals when exposed to the weather, as well as to evaluate the relative corrosivity of the atmosphere at specific locations. Because ... -
Standard Specification for Seamless, Welded, and Heavily Cold Worked Austenitic Stainless Steel Pipes
Abstract: This guide covers standard specification for seamless, straight-seam welded, and cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service. Several grades of steel shall ... -
Standard Guide for Laboratory Immersion Corrosion Testing of Metals
Abstract: 4.1 Corrosion testing by its very nature precludes complete standardization. This standard, rather than a standardized procedure, is presented as a guide so that some of the pitfalls of such testing may be avoided. ... -
Standard Specification for Lead and Lead Alloy Strip, Sheet, and Plate Products
Abstract: This specification covers the standard requirements for lead and lead alloy strip, sheet, and plate products intended for use in chemical plants, sound attenuation, roofing, vibration dampening, flashing and weather ... -
Standard Practice for Preparing, Cleaning, and Evaluating Corrosion Test Specimens
Abstract: 4.1 The procedures given are designed to remove corrosion products without significant removal of base metal. This allows an accurate determination of the mass loss of the metal or alloy that occurred during exposure to ... -
Standard Practice for Evaluating the Effects of Outdoor Weathering on Pipeline Coatings
Abstract: 4.1 Since coated pipe may be stored outdoors for long periods before burial, weathering tests described in this practice are needed to evaluate the stability of these coatings stored outdoors. The results obtained should ... -
Standard Test Method for Exoskeleton Use: Ladders
Abstract: 5.1 Ladder designs can vary greatly in, for example: number and size of steps, geometry, and materials, and for a variety of industries. Fig. 2 shows examples of various ladders. 5.2.1 Example—A test requestor instructs ... -
Standard Test Method for Measuring the Evaporation Rate of Oils and Petroleum
Abstract: 4.1 A standard procedure is necessary to establish an evaporation equation for spilled oils or petroleum products. 4.2 This procedure employs standardized equipment and test procedures. -
Standard Practice for Grasp-Type Robot End-Effectors: Split Force Measurement Apparatus
Abstract: 5.1 To design relevant performance metrics and methods for characterizing grasp-type end-effectors, this practice helps to understand the contextual or application-specific issues surrounding robotic grasping and manipulation. ...
