CACR No.52
CACR52 has just been published, featuring some potentially transformative articles for the cleanroom community. The first article reveals a scientific method for measuring airflow in non-UDAF cleanrooms, showing significantly lower rates than those suggested by current regulatory guidelines.
Another article explores how increasing the internal diameter of sample tubing in particle counting can greatly minimise losses of ≥5.0μm particles.
We also include an extract from the second edition of Bill Whyte’s Advanced Cleanroom Technology, outlining key equations for calculating airflow rates, along with a review of the book.
The article, “Is Your HEPA Filter Working Properly?” stresses the importance of site tests for HEPA filters, even those that are factory-tested, and highlights the need for certified test engineers, such as those accredited by the CTCB-I. Don’t miss these valuable insights to enhance your cleanroom practices!
