EN ISO 374-2: 2019
Determination of resistance to penetration
Two tests are included in this part of EN 374, both to assess the resistance of the glove to penetration (or freedom from holes).
Firstly the air leak test which involves inflating a glove with air pressure and then submerging it in a tank of water. Any leaks are identified by visible bubbles. The second test involves suspending a glove filled with water and examining its outer surface for water droplets.
