ASTM E23 Notched Bar Impact Testing of Metallic Materials
ASTM E23 test methods explain the Charpy (simple-beam) and Izod (cantilever-beam) tests for notched-bar impact testing of metallic materials. The importance of notched-bar impact testing and procedures for evaluating the center of the strike are provided in these standard test methods. The values expressed in SI units are considered standard.
Scope:
The standard test method of ASTM E23 tells about the behavior of metal when subjected to a single application of a force resulting in multi-axial stresses associated with a notch, coupled with high rates of loading and, in some instances, high or low temperatures.
Procedure:
In ASTM E23, a suitable specimen, a set of anvils, and specimen supports on which the test specimen is placed to receive the blow of the moving mass, a moving mass with sufficient energy to break the specimen placed in its path, and a device for measuring the energy absorbed by the broken specimen are the essential features of an impact test.

Specimen size:
For ASTM E23, the testing machine is of robust structure, like a pendulum,and built to conform to the requirements annually. Charpy impact machines are checked directly and indirectly.
Perpendicularity between the notch axis and specimen edge is 62° and the angle of notch is 61°.
Finish requirements – Ra= 2μm on notched surface and opposite face.
Data
h = S (1 – cos (β))
h1 = S (1 – cos (α))
Where,
h = initial elevation of the striker,
S = length of the pendulum distance to the center of the strike,
β = angle of fall,
h1 = height of rise, m, and
α = angle of rise.
Conclusion:
The standard test method of ASTM E23 tells about the behavior of metal when subjected to a single application of a force resulting in multi-axial stresses associated with a notch, coupled with high rates of loading and, in some instances, high or low temperatures.
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 test is a standard test method for the analysis of sulfochromate etch solutions 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.
