Standard Practice for Design, Manufacture and Material Grouping Classification of Wire Image Quality Indicators (IQI) Used for Radiography
Abstract: This practice covers the design, material grouping classification, and manufacture of wire image quality indicators (IQI) used to indicate the quality of radiologic images. This practice, applicable to X-ray and gamma-ray ... -
Standard Test Method for Melting And Crystallization Temperatures By Thermal Analysis
Abstract: 5.1 Differential scanning calorimetry and differential thermal analysis provide a rapid method for determining the fusion and crystallization temperatures of crystalline materials. 5.2 This test is useful for quality ... -
Standard Test Method for Determining Air Change in a Single Zone by Means of a Tracer Gas Dilution
Abstract: 5.1 Effects of Air Change—Air change often accounts for a significant portion of the heating or air-conditioning load of a building. It also affects the moisture and contaminant balances in the building. Moisture-laden air ... -
Standard Test Method for Autoignition Temperature of Chemicals
Abstract: 5.1 Autoignition, by its very nature, is dependent on the chemical and physical properties of the material and the method and apparatus employed for its determination. The autoignition temperature by a given method does ... -
Standard Practice for Evaluation of Antimicrobials as Preservatives for Aqueous-Based Products Used in the Paper Industry (Bacterial Spoilage)
Abstract: 5.1 This practice should be used to determine if an antimicrobial preserves pigment suspensions, dye solutions, pulp slurries, starch solutions, polymers, sizing agents, latex emulsions, and other aqueous-based materials ... -
Standard Specification for Interchangeable Spherical Ground Joints
Abstract: This specification covers standard dimensional requirements for obtaining interchangeable spherical ground joints. This specification does not include physical, chemical, and design characteristics of material used. ... -
Standard Practice for Establishing Color and Gloss Tolerances
Abstract: 5.1 Color specifications are centered around exact positions in color space. Correspondingly, gloss specifications are centered around an exact position on the gloss scale. Because it is difficult to achieve these exact ... -
Standard Test Method for Measurement of Fatigue Crack Growth Rates
Abstract: 5.1 Fatigue crack growth rate expressed as a function of crack-tip stress-intensity factor range, da/dN versus ΔK, characterizes a material's resistance to stable crack extension under cyclic loading. Background information ... -
Standard Test Method for Bromine in Chlorine
Abstract: 4.1 Low levels of bromine contaminant in chlorine cause problems in some industrial uses. This test method may be used to determine bromine in liquid or gaseous chlorine at levels as low as 4 ug/kg. -
Standard Guide for Mounting Piezoelectric Acoustic Emission Sensors
Abstract: 4.1 The methods and procedures used in mounting AE sensors can have significant effects upon the performance of those sensors. Optimum and reproducible detection of AE requires both appropriate sensor-mounting fixtures and ... -
Standard Test Method for Ball Punch Deformation of Metallic Sheet Material
Abstract: 4.1 The ball punch deformation test is widely used to evaluate and compare the formability of metallic sheet materials. Biaxial stretching is the predominant mode of deformation occurring during the test and, therefore, ... -
Standard Specification for Mineral-Insulated, Metal-Sheathed Base Metal Thermocouples
Abstract: 4.1 This specification describes the physical requirements of mineral-insulated, metal-sheathed base metal thermocouples and establishes suitable test criteria for their evaluation. 4.2 Standardized dimensional requirements ... -
Standard Test Method for Synthetic Anionic Ingredient by Cationic Titration
Abstract: 4.1 This test method offers a means of determining anionic detergents commonly found in laundry, dishwashing, and other cleaning materials. Accurate determination of the anionic active substance is highly important in ... -
Standard Test Method for Thermal Stability of Chemicals by Differential Scanning Calorimetry
Abstract: 5.1 This test method is useful in detecting potentially hazardous reactions including those from volatile chemicals and in estimating the temperatures at which these reactions occur and their enthalpies (heats). This test ... -
Standard Practice for Electromagnetic (Eddy-Current) Examination of Nickel and Nickel Alloy Tubular Products
Abstract: 5.1 Eddy-current testing is a nondestructive method of locating discontinuities in metallic materials. Signals can be produced by discontinuities originating on either the external or internal surfaces of the tube or by ... -
Standard Practice for Electromagnetic (Eddy Current/Magnetic Induction) Sorting of Ferrous Metals
Abstract: 5.1 Absolute and comparative methods provide a means for sorting large quantities of ferrous parts of stock with regard to composition, condition, structure, or processing, or a combination thereof. 5.2 The comparative ... -
Standard Practice for Referencing Suprathreshold Odor Intensity
Abstract: These practices are designed to outline two preferred procedures for referencing the odor intensities of any odorous material in the suprathreshold region on the ASTM Odor Intensity Referencing Scale. The method by which ... -
Standard Guide for Preparing Granular Pesticide Ground Applicator Calibration Procedures
Abstract: 2.1 This guide covers the calibration of row, band, and broadcast applicators. Attainment of accurate and more uniform application can reduce the quantity of active ingredient required for a given degree of control, thus ... -
Standard Test Method for Plastic Strain Ratio r for Sheet Metal
Abstract: 4.1 The plastic strain ratio r is a parameter that indicates the ability of a sheet metal to resist thinning or thickening when subjected to either tensile or compressive forces in the plane of the sheet. It is a measure ...
