Computer Software for Automating Permeation Testing Data Analysis

Data analysis for chemical protective clothing (CPC) permeation testing involves a number of equations and experimental factors. Experimenter bias and possible calculation errors are critical issues when determining permeation parameters. In order to compare results among different laboratories and manufacturers, the normalized breakthrough time is required since it is not dependent on the detection limits of the analytical system. However, calculating the normalized breakthrough time requires the use of polynomial curve fitting, polynomial derivatives, and quadratic equations. Solving these equations, without a computer program, would be very difficult. Therefore, a unique computer program using Microsoft Visual C++, referred to as “Permeation Calculator”, has been developed at the National Institute for Occupational Safety and Health/National Personal Protective Technology Laboratory (NIOSH/NPPTL) to calculate the permeation parameters. The program imports data and then calculates the permeation parameters; including breakthrough detection time, ASTM normalized breakthrough time, European normalized breakthrough time, and steady-state permeation rate. The calculation of these parameters is based on a series of strategies, approaches, and algorithms. At the end, the program displays all the permeation parameters as a report file that can be saved as a Microsoft Excel file or a text file. The program reduces the time spent on data analysis from hours to seconds.
