ASTM E8/E8M-16a. Tension tests provide information on the strength and ductility of materials under uniaxial tensile stresses. This information may be useful in comparisons of materials, alloy development, quality control, and design under certain circumstances. 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. 1.3 Exceptions to the provisions of these test methods may need to be made in individual specifications or test methods for a particular material. For examples, see Test Methods and Definitions A370 and Test Methods B557, and B557M. 1.4 Room temperature shall be considered to be 10 to 38°C [50 to 100°F] unless otherwise specified. 1.5 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. Combining values from the two systems may result in non-conformance with the standard. 1.6 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 and health practices and determine the applicability of regulatory limitations prior to use.

The management issues Lariat Technologies saw in the recycling, scrap metal and waste industry was calculation faults, duplicate entries, unnecessary paper work, no proof of transactions, no or little control of stock, no verification of products and ultimately loss of customers. For the past 17 years RecycleProX has been a market leader software. 17, 2017 Nobuto Blood Filter Strips are the bloodiest product in Sterlitech’s catalog; get some in time for Halloween sample testing! Made from high-purity cellulose fibers, these strips are structured for uniform sampling. Each strip holds approximately 0.1 mL of blood or 0.04 mL of serum. Once blood is applied and the strip has dried, researchers can analyze, store, or mail the samples without refrigeration. Studies have shown that these collection devices are easy to use and enable delayed analysis of samples. 20, 2016 The ASTM F15.22 Toy Safety Committee has just published revisions to its U.S. Toy Safety Standard, F963-16, covering the safety of all toys sold in the United States. Integral among the new changes is a provision allowing for the use of High-Definition X-Ray Fluorescence, or HDXRF, to measure the presence of toxic heavy metals in toys. Compared to traditional wet chemistry testing, HDXRF is much faster, more cost-effective, more efficient, safer and as reliable – enabling toy manufacturers and importers to. 16, 2016 Teck Metals Ltd. Was ordered to pay a $3,000,000 penalty on February 29, 2016, in British Columbia Provincial Court after pleading guilty to three offences under the Fisheries Act related to releases of effluent deleterious to fish into the Columbia River. In addition to the penalty, Teck Metals Ltd. Agreed to undertake on-site improvement projects. The company estimates that these projects, which are intended to prevent future incidents, will cost the company $50,000,000 to implement.
