Description: Auger Electron Spectroscopy (AES) is a surface-sensitive analytical technique used to determine the elemental composition and chemical state of the top few atomic layers of a solid material. It operates based on the Auger effect, which is the emission of Auger electrons when an atom in an excited state relaxes to a lower energy …
ASTM D2240 – Standard Test Method for Rubber Property—Durometer Hardness Description: Scope 1.1 This test method covers twelve types of rubber hardness measurement devices known as durometers: Types A, B, C, D, DO, E, M, O, OO, OOO, OOO-S, and R. The procedure for determining indentation hardness of substances classified as thermoplastic elastomers, vulcanized (thermoset) rubber, …
ASTM D1653 – Standard Test Methods for Water Vapor Transmission of Organic Coating Films Description: Scope 1.1 These test methods cover the determination of the rate at which water vapor passes through films of paint, varnish, lacquer, and other organic coatings. The films may be free films or they may be applied to porous substrates. 1.2 A …
ASTM D412 – Standard Test Methods for Vulcanized Rubber and Thermoplastic Elastomers-Tension Description: Scope 1.1 These test methods cover procedures used to evaluate the tensile (tension) properties of vulcanized thermoset rubbers and thermoplastic elastomers. These methods are not applicable to ebonite and similar hard, low elongation materials. The methods appear as follows: Test Method A—Dumbbell …
ASTM A123 – Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products Abstract This specification covers the standard requirements for hot-dip galvanized zinc coatings on iron and steel products made from rolled pressed and forged shapes, castings, plates, bars, and strips. This specification deals with both unfabricated products and fabricated products, for …
Description: Time-of-flight secondary ion mass spectrometry (TOF-SIMS) is an analytical technique used to study the chemical composition and molecular structure of surfaces at the nanometer scale. In TOF-SIMS, a primary ion beam is directed onto a surface, and this beam sputters secondary ions from the surface. The secondary ions are then analyzed in a time-of-flight …
Description: X-ray photoelectron spectroscopy (XPS), also known as electron spectroscopy for chemical analysis (ESCA), is a surface-sensitive analytical technique used to determine the elemental composition, chemical bonding, and electronic state of materials. In XPS, a sample is bombarded with monochromatic X-rays, which excite electrons in the sample’s surface layers. The electrons are ejected from the …
ASTM E1461 – Standard Test Method for Thermal Diffusivity by the Flash Method Description: This test method covers the determination of the thermal diffusivity of primarily homogeneous isotropic solid materials. Thermal diffusivity values ranging from 0.1 to 1000 (mm)2 s-1 are measurable by this test method from about 75 to 2800 K. Practice E2585 is …
ASTM E595 – Standard Test Method for Total Mass Loss and Collected Volatile Condensable Materials from Outgassing in a Vacuum Environment Description: This test method covers a screening technique to determine volatile content of materials when exposed to a vacuum environment. Two parameters are measured: total mass loss (TML) and collected volatile condensable materials (CVCM). …
Description: Fourier transform infrared spectroscopy (FTIR) is a non-destructive analytical technique that measures the absorption or transmission of infrared radiation by a sample as a function of frequency or wavelength. FTIR is commonly used for qualitative and quantitative analysis of organic and inorganic compounds in various fields such as pharmaceuticals, polymers, food, and environmental analysis. …
