ASTM E2298 Instrumented Impact Testing of Metallic Materials
ASTM E2298 test method establishes the requirements for performing instrumented Charpy V-notch (CVN) and instrumented miniaturized Charpy V-notch (MCVN) impact tests on metallic materials. This test provides a measurement of instrumented absorbed energy during fracture.
Instrumented Impact Testing of Metallic Materials ASTM E2298 is a standard test technique for measuring the absorbed energy involved with fracturing CVN or MCVN specimens using test machines having a dial, optical encoder, or both. Instrumented testing allows the estimation of characteristic force, partly instrumented absorbed energy, and displacement parameters. Displacement parameters provide additional information on the fracture behavior of the tested materials (in addition to the absorbed energy).
ASTM E2298 involves striking a standard notched specimen with a controlled weight pendulum swung from a set height. For every specimen tested, the absorbed energy is measured on the broken samples (fractured sample) by means of a caliper. In addition, the voltage-time curve is measured and evaluated to give the force-displacement curve. Then, the force-displacement curve is evaluated with respect to the characteristic phases of the deformation and fracture stages.
ASTM E2298 test specimen types include notch configurations such as V-Notch, U-Notch, Key-Hole Notch, and Un-notched with the capabilities of testing sub-size specimens down to ¼ size.
ASTM E2298 test is qualitative in nature and provides great information about the resilience properties of materials.
Absorbed energy is reported in Joules (J) while the percentage crystallinity and lateral expansion are optional on the test report.

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.
