Cleanroom Performance Testing

 

< Return to Services page

Cleanrooms are used throughout the medical, manufacturing, high tech, semiconductor industries and more. These rooms must meet regulatory standards of performance. This means air quality, air pollutants, temperature, and humidity among others are monitored to maintain an environment conducive to the process requirements. These can be measured and adjusted with cleanroom performance testing services.

Cleanroom Performance Testing (CPT) Services

CPT Services encompass a wide array of tests. Each facility’s requirements are determined by the facility managers. These may include:

  • Particle Counts
  • Filter Airflow Uniformity
  • Room Pressurization
  • Temperature and Humidity Measurements
  • Air Change Rates
  • Filter Scanning

Certification Process

NorthWest Engineering Service, Inc. performs NEBB Certified Cleanroom Performance Testing in accordance with client selected specifications and tests. Depending on the requirements of the cleanroom, this can be performed from the latest version of the ISO Standard 14644 or to Federal Standard 209E.

Basic performance testing to ISO Standard 14644-1 measures the ambient room particle counts for certification. Additional performance tests shown in ISO Standard 14644-3 are often performed to further document the cleanroom. Common additional tests include: room pressurization, airflow velocity, airflow uniformity, temperature and humidity, and filter scanning.

Cleanrooms can be certified at three different states of operation. An “As Built” state is just the room, without any people or equipment occupying the space. An “At Rest” state is a room with the equipment running but no people. An “Operational” state has the equipment running as well as the people operating the equipment.

“NorthWest Engineering does very critical work for us when they do our annual Cleanroom Performance Testing. There is no question about the integrity of work they do.”
