Standard Guide for Room Fire Experiments
Abstract: 5.1 This guide provides assistance for planning room fire tests. The object of each experiment is to evaluate the role of a material, product, or system in the fire growth within one or more compartments. 5.2 The relationship ... -
Standard Practice for Ultrasonic Angle-Beam Contact Testing
Abstract: 4.1 An electrical pulse is applied to a piezoelectric transducer which converts electrical to mechanical energy. In the angle-beam search unit, the piezoelectric element is generally a thickness expander which creates ... -
Standard Practice for Flux Leakage Examination of Ferromagnetic Steel Tubular Products
Abstract: 5.1 This practice outlines a procedure for examining ferromagnetic tubular products using the flux leakage method. If properly applied, this method is capable of detecting the presence and location of significant longitudinally ... -
Standard Test Method for Determining Image Quality in Direct Thermal Neutron Radiographic Examination
Abstract: 5.1 The BPI is designed to yield quantitative information concerning neutron beam and image system parameters that contribute to film exposure and thereby affect overall image quality. In addition, the BPI can be used to ... -
Standard Practice for Leaks Using the Mass Spectrometer Leak Detector in the Detector Probe Mode
Abstract: 6.1 Test Method A is frequently used to test large systems and complex piping installations that can be filled with a trace gas. Helium is normally used. The test method is used to locate leaks but cannot be used to quantify ... -
Standard Test Method for Assay of High Purity Di-tert-Butyl Peroxide Using Gas Chromatography
Abstract: 5.1 Di-tert-butyl peroxide is widely used as a catalyst and reaction initiator. Knowledge of the peroxide content is important in such applications. This test method provides a procedure for determining the active peroxide ... -
Standard Specification for Magnesium-Alloy Permanent Mold Castings
Abstract: This specification covers magnesium alloy permanent mold casting. The castings may be subjected to the heat treatment necessary to produce material that will conform to the requirements specified. Heat treatment shall be ... -
Standard Test Methods for Chemical Analysis of Stainless, Heat-Resisting, Maraging, and Other Similar Chromium-Nickel-Iron Alloys
Abstract: 4.1 These test methods for the chemical analysis of metals and alloys are primarily intended as referee methods to test such materials for compliance with compositional specifications, particularly those under the jurisdiction ... -
Standard Test Methods for Chemical Analysis of Cast Iron—All Types
Abstract: 4.1 These test methods for the chemical analysis of metals and alloys are primarily intended as referee methods to test such materials for compliance with compositional specifications, particularly those under the jurisdiction ... -
Standard Test Method for Trace Amounts of Peroxides In Organic Solvents
Abstract: 4.1 Dilute solutions of peroxides in various organic solvents frequently are used as catalysts or reaction initiators. Peroxides also can be formed through autoxidation in certain classes of compounds including ethers, ... -
Standard Terminology of Appearance
Abstract: 3.1 This terminology standard contains definitions of appearance terms applicable to the work of many ASTM technical committees. Its use by committees other than Committee E12 on Color and Appearance, and its citation in ... -
Standard Practice for Ultrasonic Testing of the Weld Zone of Welded Pipe and Tubing
Abstract: 5.1 The purpose of this practice is to outline a procedure for detecting weld discontinuities such as lack of fusion, pin holes, lack of penetration, longitudinal cracks, porosity, and inclusions by the pulse-echo method. -
Standard Test Method for Measuring Fast-Neutron Reaction Rates by Radioactivation of Iron
Abstract: 5.1 Refer to Guide E844 for guidance on the selection, irradiation, and quality control of neutron dosimeters. 5.2 Refer to Practice E261 for a general discussion of the determination of fast-neutron fluence rate with ... -
