Standard Guide for Studying Fire Incidents in Oxygen Systems
Abstract: 5.1 This guide helps those studying oxygen system incidents to select a direct cause hypothesis and to avoid conclusions based on hypotheses, however plausible, that have proven faulty in the past. -
Standard Test Methods for Determining Effects of Chemical Admixtures on Corrosion of Embedded Steel Reinforcement in Concrete Exposed to Chloride Environments
Abstract: 3.1 These test methods provide a reliable means for predicting the inhibiting or corrosive properties of admixtures to be used in concrete. 3.2 The total integrated (coulombs) current is calculated to provide an indication ... -
Standard Test Methods for Electrochemical Reactivation (EPR) for Detecting Sensitization of AISI Type 304 and 304L Stainless Steels
Abstract: 5.1 This test method describes an EPR test method for quantitatively determining the relative degree of sensitization in AISI Type 304 and 304L stainless steels. The EPR test has found wide use as a means to provide a ... -
Standard Practice for Calculation of Corrosion Rates and Related Information from Electrochemical Measurements
Abstract: 3.1 Electrochemical corrosion rate measurements often provide results in terms of electrical current. Although the conversion of these current values into mass loss rates or penetration rates is based on Faraday’s Law, the ... -
Standard Test Method for Wear and Friction Testing with a Pin-on-Disk or Ball-on-Disk Apparatus
Abstract: 5.1 The amount of wear in any system will, in general, depend upon the number of system factors such as the applied load, machine characteristics, sliding speed, sliding distance, the environment, and the material properties. ... -
Standard Guide for Liquid Dispersion of Metal Powders and Related Compounds for Particle Size Analysis
Abstract: 4.1 The method of powder dispersion in a liquid has a significant effect on the results of a particle size distribution analysis. The analysis will show a too-coarse, unstable, or nonrepeatable distribution if the powder ... -
Standard Test Method for Galling Resistance of Materials
Abstract: 5.1 This test method is designed to rank material couples in their resistance to the failure mode caused by galling and not merely to classify the surface appearance of sliding surfaces. 5.2 This test method should be ... -
