Description: Electron Paramagnetic Resonance (EPR), also known as Electron Spin Resonance (ESR), is a spectroscopic technique used to study chemical species that have unpaired electrons, such as free radicals, transition metal ions, and some defects in materials. It investigates the behavior of these electron spins in a magnetic field and provides information about their environment …
Description: Differential Thermal Analysis (DTA) is a thermoanalytical technique used to study phase transitions, chemical reactions, and thermal properties of materials by measuring temperature differences between a sample and a reference material as they undergo controlled temperature changes. Principle: DTA involves comparing the temperature of a sample with that of an inert reference material as …
Description: Dynamic Mechanical Analysis (DMA) is an analytical technique used to evaluate the mechanical properties of materials as a function of temperature, time, frequency, or other external stimuli. It measures how a material responds mechanically under dynamic loading conditions, such as stress, strain, or deformation, while subject to varying temperature or frequency. Principle: DMA applies …
Description: The Coefficient of Thermal Expansion (CTE) refers to the fractional change in size or dimensions of a material per degree change in temperature. It quantifies how a material’s dimensions respond to changes in temperature, indicating the material’s expansion or contraction with temperature variations. Principle: CTE is determined by measuring the change in dimensions (length, …
Description: The BET (Brunauer-Emmett-Teller) method is a widely used technique for determining the surface area and porosity of solid materials, particularly porous materials, catalysts, and adsorbents. It’s utilized to measure the specific surface area by determining the adsorption of gas molecules onto a solid surface. Principle: The BET method is based on the physical adsorption …
Description: Atomic Emission Spectroscopy (AES) is an analytical technique used to identify and quantify elements based on the emission of light when excited atoms return to their ground state. Here’s an overview of its workings, applications, strengths, and limitations: Principle of Atomic Emission Spectroscopy (AES): Applications of Atomic Emission Spectroscopy: Strengths of Atomic Emission Spectroscopy: …
Description: Atomic Absorption Spectroscopy (AAS) is an analytical technique used to determine the concentration of various elements in a sample. Here’s an overview of its workings, applications, strengths, and limitations: Principle of Atomic Absorption Spectroscopy (AAS): Applications of Atomic Absorption Spectroscopy: Strengths of Atomic Absorption Spectroscopy: Limitations of Atomic Absorption Spectroscopy: In summary, AAS is …
ASTM A380 – Standard Practice for Cleaning, Descaling, and Passivation of Stainless Steel Parts, Equipment, and Systems Description: Abstract This practice covers the standard recommendations and precautions for cleaning, descaling, and passivating of new stainless steel parts, assemblies, equipment, and installed systems. Consideration shall be given in the design of parts, equipment, and systems that …
ASTM A370 – Standard Test Methods and Definitions for Mechanical Testing of Steel Products Description: Significance and Use 4.1 The primary use of these test methods is testing to determine the specified mechanical properties of steel, stainless steel, and related alloy products for the evaluation of conformance of such products to a material specification under the …
ASTM A342 – Standard Test Methods for Permeability of Weakly Magnetic Materials Description: Significance and Use 3.1 This test method is suitable for specification acceptance, design purposes, service evaluation, regulatory statutes, manufacturing control, and research and development. 3.2 Because of the restrictions on the specimen shape and size, this test method is most often used to evaluate …
