The Advantages of ASTM International to the Materials Engineer Edward L.Hibner Special Metals Corp. Huntington, WV 25705 ASTM (the American Society for Testing and Materials) International is the largest organization in the world for developing and pub lishing voluntary, full-consensus standards. The basics of ASTM’s process have remained unchanged for the past 100 years. A balance of users, producers and general interest members through strict balloting and due process procedures insures the credibility of the standards developed through ASTM. ASTM’s process calls for the cooperation and participation of all who have a stake in the outcome. Voluntary, full consensus standards are developed with the belief that a broad range of input from consumers and experts from industry and academia will insure their technical competency and credibility. Technical committees develop different types of standard documents to meet the needs of the industries they represent. Everyone has a right to participate and if dissatisfied, an appeal is possible at any step in standard development. ASTM standards are continually reviewed to insure soundness, while keeping them current. For more than 30 years, ASTM Committee G01 on Corrosion of Metals has served the engineering community in furthering the technology that aids in understanding corrosion-related problems. ASTM has 32,000 members and 132 committees. Committee G01 has a technical subcommittee organization structured to focus on specific types of corrosion observed in service, techniques or tools to characterize corrosion behavior, and environments such as natural waters or soils. These subcommittees are listed in Table 1. Corrosion test methods have been developed to define procedures for identifying or evaluating corrosion properties of a given product. An example known to most ASM members is ASTM Test Method G48 for Pitting and Crevice Corrosion Resistance of Stainless Steels and Related Alloys by Use of a Ferric Chloride Solution. ASTM practices and guides, such as Standard Guide G4 for Conducting Corrosion Coupon Tests in Field Applications and Standard Practice G31 for Laboratory Immersion Corrosion Testing of Metals, provide instructions, options and recommend courses of action for evaluating corrosion resistance of ma terials. Materials engineers who use ASTM standards do not have to reinvent the wheel. They are building on the knowledge of countless man and woman hours, and years of practical experience that have gone into the standards development process. Standards terminology creates a common language for corrosion knowledge. Standards, practices and guides on wear, erosion and metal corrosion, found in volume 03.02 of the Annual Book of ASTM Standards, contribute to the quality of materials, products, systems and services used by materials engineers. Examples of new standards recently developed by ASTM Committee G-1 are: (1) Standard Test Method for Evaluating Corrosion Resistance of Chemically Passivated Aluminum Alloys by Electrochemical Impedance Spectography (EIS), and (2) Standard Practice for Laboratory Simulation of Corrosion Under Insulation. Examples of new standards currently under development by ASTM Committee G-1 are: (1) Standard Test Method for Determining the Corrosivity of Artificial Soil, and (2) Standard Test Method for Determining the Chloride Threshold Value for Corrosion of Steel in Concrete. In summary, the benefits of ASTM to the ASM member are: Improved Communication - A common language promotes understanding between customers, manufacturers and distributors, organizations and associations, and government agencies. Lower cost and time savings - Using the standards brings new products, processes and plants on- line sooner, avoids duplication of effort, reduces lead time and increases purchasing power. A quick response to customers and markets - Standards development moves as quickly as the need dictates: many committees have accelerated standards programs. Competitiveness. Professionals can help maintain their companies’ competitive edge in the marketplace by participating in the development of world-renowned standards. Quality, safety and reliability of products - Standards that establish acceptable requirements, include proven methods and practices and define levels of product performance promote high quality goods and services. Professional development - Members have the opportunity to work with colleagues and recognized in their field. Technology transfer - Discussions at ASTM meetings help to bridge the gap between research and development of new products and processes and commercial liability.
