ASTM E10-10 Test for Brinell Hardness of Metallic Materials
ASTM E10-10 is used to determine Brinell Hardness of Metals by the Brinell indentation hardness principle. In this test, an indenter forces a load on the specimen for a specified time. The load is removed, and the resulting indentation's diameter is measured to calculate The Brinell hardness number.
Scope:
ASTM E10-10 test method measures the hardness of metals in terms of their ability to withstand a load without forming a dent. This test is used to calculate the Brinell hardness number, which correlates to tensile strength, wear resistance, ductility, or other physical characteristics of metals. The information gathered from this test can be used in the quality control and the selection of materials.
Brinell hardness tests are extensively used for acceptance testing of commercial shipments. Brinell hardness testing at a specific location does not represent the physical characteristics of the whole product.
Test Procedure:
Brinell hardness is determined by forcing a hardened steel or carbide ball of known diameter under a known load into a surface and measuring the diameter of the indentation with a microscope. The Brinell hardness number is obtained by dividing the load, in kilograms, by the spherical area of the indentation in square millimeters; this area is a function of the ball diameter and the depth of the indentation.
Specimen size:
There is no standard shape or size for a Brinell test specimen, but the test specimen should conform to the following: The specimen should be thick enough that no bulge appears on the part of the specimen opposite the indentation when the load is applied. The thickness of the specimen should be at least ten times the depth of the indentation. The minimum width should conform to the requirements for indentation spacing.
Data:
Brinell hardness number:
BHN = Brinell hardness number
P = applied load
D = diameter of the indenter ball in mm, and
d = measured mean diameter of the indentation in mm
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.
