Testing Spotlight
Dye Penetration testing is used to find channel leaks through the seals formed by a transparent film and porous material. This qualitative test will find channel leaks through a seal as small as 50 microns. To conduct Dye Penetration testing, a dye and surfactant solution are injected into the medical device packaging. Each seal is exposed to the dye penetrant for 5-20 seconds. During this time, the trained operator will inspect the seals for dye fluid coming through the seals. The release of dye through a channel leak would constitute a failure of the package integrity, and according to ISO 11607, a breach of sterile integrity.
Solar Solutions
Helping to Move Technology Forward
Photovoltaic technologies will play a vital part in the world’s energy supply as the costs and negative impacts of traditional energy technologies continue to grow. One of the challenges of this technology is producing modules that are robust enough to withstand the environmental, mechanical, electrical and other challenges that will be encountered throughout the product’s life cycle. Westpak has the knowledge and expertise to help you verify your product’s durability; giving you a high degree of confidence in a module’s real-world reliability.
