תיאור
The Bowie Dick Test Pack is a unique
combination of advanced Browne Intelligent Ink
Technology and the original Bowie Dick concept.
A successful test confirms that steam penetration
into a test pack is rapid and even and, by
implication, that air and other non-condensable
gases have been effectively removed. The
chemical indicator sheet at the centre of the pack
shows a defined colour change from yellow to
dark blue/purple when exposed to a specific
combination of time, temperature and steam.
Conforms to ISO 11140-1 Type 2
134 ˚C–137 ˚C for up to 3.5 minutes
