|Committee on Paint and Related Coatings to Hold Mini-Symposium on Statistics and Standardization
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 trends. The following three lectures will be given during the two-hour event.
Statistical Requirements Inside and Outside ASTM
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 That standard has been replaced by ISO 9001:2000, with the requirements for the new standard being more extensive.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 are easily met by using basic statistical techniques.
This presentation, which will be given by Robert Morrison, is an overview of the new requirements and a comparison with ASTM statistical requirements. Also, the potential impact on the coatings industry of the proposed U.S. Environmental Protection Agency statistical standard, Method 301, will be discussed.
Robert Morrison is a senior chemist for Millennium Chemicals, a Lyondell Company. Morrison has worked for Millennium Chemicals for 37 years, and is now responsible for Global Quality Assurance. He is an ISO lead auditor, and is a statistical resource for Millennium’s Six Sigma program. Morrison chairs Subcommittee D01.20 on Quality Assurance and Statistics.
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 demonstrate how ranking is often the superior method. The rated and ranked data from a visual comparison of six reflective sheetings for whiteness will be used to demonstrate the effectiveness of each approach.
Depending on the response, the ranking approach can become cumbersome to conduct as the specimen size increases. Food testing would be such an example and (possibly) the appearance of weathered specimens. In such cases a balanced incomplete block (ranking) approach can be used. This will also be discussed.
Louis Asher started working at 3M in 1969 as a laboratory quality engineer and has held a variety of laboratory positions (quality, technical service, research and statistics). He has spent the last four years as a manager in the 3M Six Sigma Process and has taught a variety of Six Sigma subjects to some 2,500 students.
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 session, presented by Timothy Brooke, will cover a detailed overview of all aspects of the program.
Timothy Brooke is a director in the Technical Committee Operations division of ASTM International. Brooke has worked for ASTM for 10 years and has been the staff manager for Committee D01 on Paint and Related Coatings, Materials and Applications for several years. //
