ASTM International Subcommittee A01.19 on Sheet and Strip Steel has made three significant changes to ASTM standards under its jurisdiction. The changes are: • Reporting of boron levels made mandatory; • Changes to size limitations of general requirements and product standards for hot rolled material; and • Addition of grades 90 and 100 for hot rolled sheet and strip products. Subcommittee A01.19…, Boron Reporting, Boron is often added to low carbon steels to achieve lower hardness and increased formability; however, the mechanical properties of cold reduced and annealed material produced from hot rolled coils containing boron are affected by its presence. The differences may or may not be desired, but the effects are important and cold rolled steel manufacturers need to be informed of the presence of…, Size Limitation Changes, The general requirements for hot rolled sheet and strip products are spelled out in Standards A 568/A 568M , Specification for Steel, Sheet, Carbon, Structural, and High-Strength, Low Alloy, Hot-Rolled and Cold-Rolled, General Requirements for, and A 635/A 635M , Steel, Sheet and Strip, Heavy-Thickness Coils, Hot-Rolled, Carbon, Structural, High-Strength Low-Alloy, and High-Strength Low-Alloy…, Ultra-High Strength Steel Grades, ASTM standards A 1011/A 1011M and A 1018/A 1018M were changed to include grades with 90 and 100 ksi [620 and 690 MPa] minimum yield strength. These grades have the designation ultra-high strength (UHSS) as a way to differentiate them from the high strength low alloy with improved formability (HSLAS-F) designation. The UHSS grades may achieve their high strength by some measure of transformation…

ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications will hold its annual mini-symposium on Jan. 24, 2006, at the Embassy Suites Hotel in Ft. Lauderdale, Fla. The focus of the sessions will be on the role and use of statistics in the development of standard test methods, with emphasis on recent developments. The following three lectures will be given during…, Statistical Requirements Inside and Outside ASTM International, Many coatings and raw material manufacturers have registered to the ISO 9002 standard. That standard has been replaced by ISO 9001:2000, with the requirements for the new standard being more extensive. However, some of the new requirements can be met by using basic statistical techniques. This presentation, which will be given by Robert Morrison, is an overview of the new requirements and compare…, The Use of Ranked vs. Rated Data in the Evaluation of Weathered Specimens or Material, The evaluation of specimens after weathering can be handled by a number of approaches; two of these are rating and ranking. Rating requires one to compare the specimens against a scale (i.e., 1 to 10). Ranking, on the other hand, requires the direct comparison of the specimens against each other. Louis Asher will make this presentation, which will center on these two approaches and will…, ASTM International Interlaboratory Study Program, ASTM International recently approved a new Interlaboratory Study Program. Through this program, ASTM is providing staff support and financial resources to technical committees by offering assistance with the identification of participating laboratories, overseeing the generation of sample distribution, collecting data, and generating precision and bias statements and research reports. This…

ASTM International Subcommittee D01.23 on Physical Properties of Applied Paint Films has approved three new standards that each deal with different types of measurements for paint coatings. Subcommittee D01.23 is under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications. Titles and descriptions of each new standard follow. , D 6991, Test Method for Internal Stresses in Organic Coatings by Cantilever (Beam) Method, Test Method D 6991 covers the procedure for measuring internal stresses in organic coatings by using the cantilever (beam) method. The test method can be used to determine the internal stresses in coatings after they have cured. Most organic coatings shrink when they cure. This induces an internal stress in the coatings. If the substrate is flexible, such as a vinyl composition tile, and has…, D 7091, Practice for Nondestructive Measurement of Dry Film Thickness of Nonmagnetic Coatings Applied to Ferrous Metals and Nonmagnetic, Nonconductive Coatings Applied to Nonferrous Metals, The development of D 7091 is the result of subcommittee discussions on the need to revise or replace D 1186, Test Method for Nondestructive Measurement of Dry Film Thickness of Nonmagnetic Coatings Applied to a Ferrous Base, and D 1400, Test Method for Nondestructive Measurement of Dry Film Thickness of Nonconductive Coatings Applied to a Nonferrous Metal Base. Rather than revising or…, D 7187, Test Method Measuring Mechanical Aspects of Scratch/Mar Behavior of Paint Coatings by Nanoscratching, Test Method D 7187 determines the resistance to mar and scratch of paint coatings on smooth, flat surfaces. The standard, which had its origin in a paper presented by Li Lin, DuPont, at the 2002 Committee D01 Centennial symposium on new directions in coatings performance technology, is a possible solution to recent searches within the automotive industry for a better way to measure the scratch…

, New ASTM Committee to Develop Standards That Will Facilitate New System Designs and Industry Growth, ASTM International, one of the largest voluntary standards development organizations (SDOs) in the world, today announced the formation of ASTM Committee F41 on Unmanned Undersea Vehicle (UUV) Systems. This important standards initiative was driven by the cooperative efforts of the United States Navy and UUV industry stakeholders to facilitate new UUV system designs and enable next-generation…, Critical Role in Oceanographic Research, Commercial and Military Applications, UUVs have a notable history dating back to the early 1980s. Early systems built on their manned submersible predecessors and helped transform oceanographic research during the decade. Used by the academic community in notable deep-sea expeditions, such as the discovery and exploration of the wreck of the Titanic, UUVs have played a critical role in ocean surveying, environmental monitoring, and…, UUV Growth and Evolution: ASTM Standards Will Help Lead the Way, Todays UUV industry includes two classes of systems: remotely operated vehicles (ROVs), which are attached to a mother-ship by a long cable; and autonomous underwater vehicles (AUVs), which operate without a tether. To better meet the challenges of emerging applications, existing UUV systems must evolve with new technology. Specific areas of need include greater interoperability among…, Fast and Efficient Standards Development Through the ASTM Process, Led by the Association for Unmanned Vehicle Systems International (AUVSI), the premier trade association for the unmanned systems industry, UUV stakeholders selected ASTM International as the SDO best suited for the development of new international industry standards. With a proven consensus process and state-of-the-art standards development infrastructure, ASTM International was best positioned…, Public/Private Sector Collaboration under the ASTM Umbrella, ASTM Committee F41 is another example of the long-standing partnership between the public and private sectors in developing consensus standards under the ASTM International process. F41 brings together technical experts from the UUV industry, federal government, trade associations and academia to develop voluntary consensus standards pertaining to UUV design, safety and performance including…

Most standard hardness tests for steel, including the Brinell, Vickers and various Rockwell tests, are generally classified as bench testers. This means that the component being tested needs to be taken to the machine for hardness to be determined. In order to test larger pieces, such as forgings, a section would need to be removed from the forging in order for it to be tested. Since this is not…
