Windshield Edge Stress

Windshield Edge Stress

The primary tool for measuring windshield edge stress is the EdgeMaster 2 real-time PSA (Photoelastic Stress Analysis) system with integrated edge guide. This easy to use hand-held system is specifically designed to slide along the edge of the windshield and reflect light off black frit to measure windshield edge stress. Measurements can be logged at key locations.

1. Positioning the EdgeMaster™ 2

Step 1 – Positioning: The first step is positioning. Simply place and hold the EdgeMaster™ 2 on the edge of the glass to position the insturment.

2. Utilize the Stop Guide

Utilize the “Stop Guide” to help position the EdgeMaster 2 for consistent data collection, sample after sample.

3. Capture the Data

Press the data capture button and the data, along with all related critical values, are placed in a table and data file.

4. Present & Report

After the measurements have been made, presentation and reporting of the data is quickly accomplished in Microsoft Excel.

5. Analyze Data

For in-depth analysis, DeltaVision Software is the solution. The software is license free and quickly installs for detailed data viewing and reporting.

Windshield Area Stress

Windshield Area Stress

The GFP 1600 is the tool of choice for general area stress measurement. The system can be used with any c-mount lens, including zoom lenses, to conveniently image broad areas and/or close-up details. Combined with a flat-panel illuminator (GFP1600 FPI), full windshield stress images can be acquired easily, in seconds.

Although not as common in windshields, the GFP 1600 FPI is a powerful tool to document temper patterns. It measures the average stress through the glass and can show imbalance in the tempering, although it does not explicitly provide the surface stress or (skin stress). Examples can be found in sidelite/backlite applications.

Windshield Thermal Stress

Windshield Thermal Stress

For thermal stress, the GFP 1600 FPI is quick enough to monitor slower transient thermal stress events like those induced by window defrosters and wiper heaters. The system can be equipped with any c-mount lens, including zoom lenses, to conveniently image broad areas and/or close-up details.

For faster thermal transients, the GFP2600 real-time inspection system can be used to acquire video. The system is small and nimble; however, the integrated fixed focal length lens requires a bit more set up changes to acquire a range of field-of-views. Nonetheless, if video is desired, the GFP2600 would be the tool of choice.
