How is Steam Quality Testing related to Wet Pack Troubleshooting?

The Steam Quality Test procedure develops data on the dryness, purity, and stability of the steam
supply. ST-79 and EN-285 procedures develop the data, and we test according to those
procedures. What makes us different is we ALSO test the valves, insulation and water supply that
can impact steam quality.
You rely on the steam system to deliver thermal energy that is clean, dry, and sterile... do you figure out
what's causing the problems? That's our job.

What does industry say about sterilizers and wet pack problems?
    "Perhaps the most  frustrating and confounding dilemma that we face
    using steam sterilization is the occurrence of wet packs...
    "Wet packs represent an economic loss to the institution because goods
    must be reprocessed. Unrecognized, they are a hazard to the patient. "

On Site Testing and Troubleshooting
We solve problems with sterilizers, autoclaves, wet loads and staining. We do steam quality
according to ANSI/AAMI ST79, Comprehensive guide to steam sterilization and sterility
assurance in health care facilities
(2010), and European Standard EN285.
Sterilizers and autoclaves are critical components in health care, life sciences, institutional, and
research facilities... but since they are open-ended steam users, poor steam quality (water in the
line) can cause
major problems. (PDF article)
