For many years there has been an ‘Acceptance Criterion’ for Porous Load/Hardware autoclave cycles, known as the, ‘Equilibration Time’. A change in the definition of the ‘reference measurement point’ in BS EN 285:2006+A1:2008 is causing concern.

I was asked to write an article for ‘GMP Review’ magazine following a comment I made during a conference about this issue. Click here to read the whole article - 
I would like to thank GMP Review for their input and the publishing of this article.
