The ISSA Clean Standards


The ISSA family of Clean Standards establishes a framework to help schools and other institutional facilities objectively assess the effectiveness of their cleaning processes using ATP meters in conjunction with a more traditional audit process.  Based on the philosophy of “Clean, Measure, Monitor,” the ISSA Clean Standards contribute to the quality of the indoor environment by focusing on:

  • The desired levels of cleanliness that can reasonably be achieved
  • Recommended monitoring and inspection procedures to measure the effectiveness of cleaning
  • How to use the measurement and inspection results to assess and improve cleaning processes and products, ultimately resulting in a clean, healthy, and safe indoor environment.
