This Recommended Practice (RP), IEST-RP-CC018.5, provides guidance for maintaining a cleanroom at the level for which it was designed. This document is intended as a guide for establishing appropriate housekeeping procedures essential for the overall contamination control program of the cleanroom. In addition, test procedures are provided for use in establishing the frequency of housekeeping and monitoring the effectiveness of the housekeeping.
The test methods also are designed to help determine appropriate levels of surface cleanliness for specific cleanrooms.
RP-CC018 was recently updated to improve the effectiveness and efficiency of cleaning and to improve the ergonomics’ of these techniques, including a new wall cleaning method, wet mopping system, and techniques that are easier for applying a cleaning solution to a wall to reduce back and shoulder fatigue.
