摘要

AT ITS MAY 2004 MEETING, THE EXECUTIVE subcommittee of E01 on Chemical Analysis of Metals, Ores, and Related Materials unanimously committed to develop and implement performance-based test methods for the quantitative analysis of materials under its jurisdiction. Performance-based test methods define general approaches for sampling, sample preparation, and making measurements on a specified type of material. They set maximum allowable uncertainties for each component of uncertainty of each measured constituent over its validated concentration range. The key criteria of compliance with a performance-based standard test method is the quality of data generated (uncertainty) rather than adherence to procedure. The new E01 performance-based approach is based on ASTM standards E 691, Practice for Conducting an Inter-laboratory Study to Determine the Precision of a Test Method; E 1601, Practice for Conducting an Interlaboratory Study to Evaluate the Performance of an Analytical Method; E 2165, Practice for Establishing an Uncertainty Budget for the Chemical Analysis of Metals, Ores, and Related Materials, and a proposed new standard, Practice for Designing and Validating Performance Based Test
