PURPOSE: To verify the capability of the Cleanroom air handling equipment to maintain temperature within design specification.

INSTRUMENTATION: Extech Hygro-Thermometer - Calibration documents for equipment used in testing are included in the certification report.

PROCEDURES: This test is recommended for areas where temperature and moisture levels are primarily controlled for purposes of worker comfort rather than process or equipment requirements. When processes require strict temperature control, a more comprehensive test is performed.
  • Allow room to operate for 24 hours before testing.
  • Measure the temperature at a minimum of one location for each temperature control zone.
  • Place each sensor at the designated location at work-level height.
  • Record the time and temperature reading at each location.
ACCEPTANCE: Temperature and uniformity requirements are a matter for agreement between the buyer and the seller.
