The significant differences between the two tests are that the test forces are smaller for the Rockwell superficial test than for the Rockwell test. The same type and size indenters may be used for either test, depending on the scale being employed. Accordingly, throughout this standard, the term Rockwell will imply both Rockwell and Rockwell superficial unless stated otherwise.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. A Summary of Changes section appears at the end of this standard.

In order to confirm that all changes are noted by your organization, you may want to purchase the Redline Edition, which provides you not only with the new 2013A Edition, but also a copy of the previous edition complete with the markup displayed. You can purchase all current and many obsolete ASTM standards at the Document Center webstore,. Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com). You’ll want to be sure that you always purchase your ASTM Standards from a reputable dealer like Document Center Inc.

The test principles, testing procedures, and verification procedures are essentially identical for both the Rockwell and Rockwell superficial hardness tests. The significant differences between the two tests are that the test forces are smaller for the Rockwell superficial test than for the Rockwell test. The same type and size indenters may be used for either test, depending on the scale being employed.

Adobe flash cs6 serial number generator. ASTM E8 – Tensile Testing of Metals To request a quotation for any test email for a prompt reply The ASTM E8 method covers the tension testing of metallic materials in any form at room temperature, specifically, the methods of determination of yield strength, yield point, tensile strength, elongation, and reduction of area. Tension tests determine the strength and ductility of materials under uniaxial tensile stresses.

2013A Edition, “Standard Test Methods for Tension Testing of Metallic Materials,” has just been released. It’s available from Document Center Inc. In either paper format or pdf download. Starting in 2008, this standard has been the integrated edition for the and (both of which were withdrawn at that time.) The standard is a collection of test methods that cover the tension testing of metallic materials. The items to be tested can be in any form and at room temperature. The methods cover the determination of yield strength, yield point elongation, tensile strength, elongation and the reduction of area. Tension tests are useful in comparisons of materials, alloy development, quality control and design.

Touchstone Engineers have performed both standard and customized ASTM E8 testing. In addition to mechanical testing capability, for tests such as ASTM E8 and many other ASTM methods, Touchstone can conduct complete metallurgical and/or failure analysis using its laboratories for light microscopy, scanning electron microscopy (SEM), and metallography.

The E8 committee brings the following changes to your attention: • Section 3.1 was replaced, • Sections 3.1.2, 3.1.7, 3.1.8, 3.1.12 and 3.2.1 were added, • Sections 3.1.3, 3.1.4, 3.1.11 were reformatted, and • Note 32 was added.

The values stated in SI units are to be regarded as separate from inch/pound units. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other.

If you need to conduct tensile tests according to ASTM E8, please read the entire specification from the relevant ASTM publication. ASTM E8 Metal Tensile Testing • Measure and record the specimen dimensions necessary to determine the cross sectional area at its smallest point. The original cross sectional area is used for all engineering stress calculations. • Use ink and a scribe or punch to place gage marks on the test specimen at the appropriate gage length.

The results of tension tests of specimens machined to standardized dimensions from selected portions of a part or material may not totally represent the strength and ductility properties of the entire end product or its in-service behavior in different environments. These test methods are considered satisfactory for acceptance testing of commercial shipments. The test methods have been used extensively in the trade for this purpose. Scope 1.1 These test methods cover the tension testing of metallic materials in any form at room temperature, specifically, the methods of determination of yield strength, yield point elongation, tensile strength, elongation, and reduction of area. 1.2 The gage lengths for most round specimens are required to be 4D for E8 and 5D for E8M. The gage length is the most significant difference between E8 and E8M Test Specimens Test specimens made from powder metallurgy (P/M) materials are exempt from this requirement by industry-wide agreement to keep the pressing of the material to a specific projected area and density.

Then install the specimen in the grips and start loading the sample. The speed of testing is generally specified in one of three manners: a) the rate of straining of the specimen; b) the rate of stressing of the specimen; or c) the rate of separation of the crossheads. In addition, the test rate is to remain constant through yield but can then be increased when determining ultimate tensile strength and elongation at break. See the ASTM E8 specification for more details. • Run the test until specimen failure or fracture. Remove the broken sample from the machine and fit the fractured ends together. Measure the distance between the gage marks to the nearest 0.05 millimeters.

The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. This standard does not purport to address all of the safety concerns, if any, associated with its use.
