Inspection and Dye Ingress Testing Results for Vials Processed with Misaligned Capping Machine, Replicating Neck Crack Damage Introduction
Glass Type | Vial Quantity Processed by Capping Machine | Human Inspection | Dye Ingress Testing |
---|---|---|---|
Percent Cracked | Percent Leaking | ||
Borosilicate | 400 | 3.25% | 0.5% |
Strengthened Aluminosilicate | 200 | 0% | 0% |
Human inspection identified 13 (3.25%) borosilicate vials that contained neck cracks, while no (0%) strengthened aluminosilicate vials were identified as cracked. Leak testing of these vials showed that two (0.5%) of borosilicate vials exhibited leaking cracks and none (0%) of the strengthened aluminosilicate vials leaked.
