Download or read book Automated Laboratory Testing Methods for Specific Gravity and Absorption Verified to Match the Current Method Results written by Arudi Rajagopal and published by . This book was released on 2009 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty six coarse aggregate (12 gravel, 10 lime stone, 4 slag) and nine fine aggregate (4 lime stone, 3 natural sand, 2 slag sand) materials were collected from various sources in Ohio. Specific gravity and water absorption of the coarse aggregate samples were determined using CoreLok and ASTM C 127 procedures while testing of fine aggregate samples involved CoreLok, SSDetect and ASTM C 128 procedures. All the tests were performed in a single laboratory and by the same technician. The primary intent of the study was to investigate the ability of CoreLok and SSDetect to obtain faster results while, at the same time, improving the accuracy of results. The results led to the following conclusions: Coarse Aggregates: CoreLok bulk specific gravity (Gsb) values are up to 8% higher than the ASTM C 127 Gsb values. The difference between the corresponding apparent specific gravity (Gsa) values vary from 0 to 12%. The CoreLok absorption values are 1 to 81% lower except for two slag samples. These differences are statistically significant at 95% confidence interval. Fine Aggregates: The SSDetect Gsb results closely follow the ASTM C 128 values. CoreLok Gsb values are moderately higher than ASTM and SSDetect for natural sand, but lower for slag. Gsa results of all the three test procedures follow each other closely. These differences are not statistically significant. The difference in absorption values between CoreLok and ASTM C 128 procedure ranges from 1.5% to 243.7%. In case of SSDetect vs. ASTM, this difference is 0.9% to 124.2%. An in-depth absorption study of coarse aggregates using CoreLok highlighted some inconsistencies in the procedure. The principal recommendation of the study for the Ohio Department of Transportation is to continue specific gravity and absorption tests of coarse and fine aggregates using the traditional ASTM procedures.

Download or read book Analytical Method Validation and Instrument Performance Verification written by Chung Chow Chan and published by John Wiley & Sons. This book was released on 2004-04-23 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Validation describes the procedures used to analyze pharmaceutical products so that the data generated will comply with the requirements of regulatory bodies of the US, Canada, Europe and Japan. Calibration of Instruments describes the process of fixing, checking or correcting the graduations of instruments so that they comply with those regulatory bodies. This book provides a thorough explanation of both the fundamental and practical aspects of biopharmaceutical and bioanalytical methods validation. It teaches the proper procedures for using the tools and analysis methods in a regulated lab setting. Readers will learn the appropriate procedures for calibration of laboratory instrumentation and validation of analytical methods of analysis. These procedures must be executed properly in all regulated laboratories, including pharmaceutical and biopharmaceutical laboratories, clinical testing laboratories (hospitals, medical offices) and in food and cosmetic testing laboratories.
