Glass in building - Procedures for goodness of fit and confidence intervals for Weibull distributed glass strength data

This standard establishes a structured methodology for analyzing mechanical strength data specifically for glass products utilized in building construction. It addresses the statistical challenges associated with the variability inherent in glass materials by applying the Weibull distribution model. The document provides detailed procedures for evaluating the goodness of fit for collected strength data and outlines the calculation of confidence intervals necessary for reliable engineering assessments. By utilizing this approach, technical professionals can better quantify the uncertainty in strength measurements, which is critical for structural safety evaluations. The guidance covers the collection of experimental data, the application of specific statistical formulas, and the interpretation of results to determine the reliability of the glass under load. This systematic framework ensures consistency in how strength characteristics are reported and verified across different testing scenarios. It serves as a reference for laboratories and engineers requiring rigorous statistical validation when assessing the performance of architectural glazing systems. The text focuses solely on the procedural aspects of data fitting and interval estimation without addressing regulatory compliance or market implications.
