If another condom in the same package should break, keep the unused condoms and call the manufacturer. Lot number tracking will help get to the source of the problem. Most people don't realize that condoms are classified as medical devices. There are stringent quality controls and testing that Ansell uses in the manufacture of condoms. The company has a quality assurance and testing program that meets standards for more than 100 countries worldwide, and its condoms must meet more than 24 international requirements.
Every single condom is tested electronically for holes.
In addition, samples of every batch of condoms undergo inflation testing. A typical condom will inflate to about three feet high and one foot wide before it bursts. Samples of every batch of condoms also are tested for water leakage. Finally, other samples of condoms are stretched lengthwise and crosswise to test for tensile strength and elongation. Ansell voluntarily retains samples of every batch of condoms produced.
