ASTM E2714 test method explains the mechanical properties of homogeneous materials by creep-fatigue deformation or cracks formation under isothermal conditions. The strain values are considered, and the cyclic measurements are taken while maintaining the temperature and quality of the material. The final results are expressed in SI units.
ASTM E2714 method forms a standard for material research and development, process and quality control, mechanical design, product performance, and failure analysis of homogeneous materials. It helps select defect-free engineering materials by detecting deformation and cracks leading to cyclic damage. The effects of oxidation are considered, and data is recorded for damage condition analysis. The constructive deformation is detected, and material characteristics like development, assessment, verification, frequency, and temperature tolerance are studied.
A tension-compression fatigue machine and a loading system with a force transducer, loading grips, and test specimens are used to perform the test. The test specimens are attached to the loading grips, and different cycle shapes are generated. Elastic modulus and coefficient of thermal expansion are measured to detect any changes in force and displacement. An extensometer is used for measuring displacements. The test specimen is heated and stressed at the rate of 10% of its yield stress. Crack formation is detected by a direct current or alternating current electrical potential drop-crack monitoring system. Creep fatigue testing helps see physical damage during the use.
A specimen with a diameter of 5 mm, length 1.5 d, radius twice the diameter, and mean roughness less than 0.2 µm is used.
Cyclic stress-strain deformation response, cyclic relaxation deformation response, cyclic hardening and softening response, and cycles of formation of cracks in test specimens are recorded at a specific temperature of less than 2°C.
ASTM E572 test method covers the analysis of stainless and alloy steels by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). It provides rapid, multi-element determinations with sufficient accuracy to assure product quality.
The ASTM D2674 is a standard test method for the analysis of sulfochromate etches solution used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
ASTM G65 measures the resistance of metallic materials to abrasion using the dry sand/rubber wheel apparatus. The quality, durability, and toughness of the sample are determined using this test. Metallic materials are ranked in their resistance to scratching abrasion under a controlled environment.
ASTM E2141 test methods provide accelerated aging and monitoring of the performance of time-dependent electrochromic devices (ECD) integrated in insulating glass units (IGU). This test helps to understand the relative serviceability of electrochromic glazings applied on ECD.
ASTM C724 test method is used in analyzing the quality and ease of maintenance of a ceramic decoration on architectural-type glass. This test method is useful in the acknowledgment of technical standards.
