NiGK’s BDPACK is a pre-assembled disposable Bowie & Dick type test. This product complies fully with ISO11140-5. After processing, the indicator area of the sheet changes from white to black. The result can be interpreted by verifying the color change. With the proper cycle, most of the center area of the indicator sheet evenly changes from white to black or blackish brown. Ineffective pre-vacuums, air-leaks, or NCGs(non- condensable gases) in the supplied water can lead to results indicating failure.
If the center area does not change color to black/blackish brown or the whole area is light, this indicates failure.
