ISO 9008:1991

Test Materials: ISO 9008 specifies that the materials used for testing should include the test object (e.g., bottles or containers) and precise measurement tools such as verticality gauges or laser alignment equipment. These materials are essential for determining the deviation of the body from the vertical axis with high accuracy.
Test Process: The test process involves positioning the test object in a fixed position and using specialized equipment to measure any deviation from the vertical. Measurements are taken at specified points around the object to ensure a comprehensive analysis of its alignment.
Test Result Interpretation: Results are interpreted by comparing the measured deviations to established tolerance limits. A deviation beyond the acceptable range indicates a failure to meet ISO 9008 standards, signaling issues with product alignment and potential defects in manufacturing.
