Testing Cleanroom Environments

Testing Cleanroom Environments

All Cleanroom process environments must remain unfailingly clean, so merely filtering the factory’s air is inadequate. To minimise particle contamination it is important to build separate environments, called cleanrooms. These areas allow particle limits to be maintained at measurable and controllable levels locally.

Testing Cleanroom Environments

Clean rooms environments achieve these acute cleanliness levels by maximising laminar airflow and minimising particle traps. Laminar airflow is air moving in one direction, which allows particles to be swept away from an area within the cleanroom. Particle traps within a cleanroom environment are areas where particles gather and escape laminar airflow, such as the corners of the rooms and behind machinery and instrumentation, careful cleanroom design and placement of room furniture can minimise these areas.

In efficient cleanrooms HEPA filters installed in the ceiling allow filtered air to pass down toward the floor. The floor tiles have small holes that allow the air to pass under the floor, where air-returns (air ducts) transport the air back to the ceiling HEPA filters. This filtration process can exchange the clean room’s entire volume of air more than thirty times per hour, resulting in a very clean environment while minimising the movement of air particles.

Clean Room Commissioning 

To further reduce contamination within a cleanroom requires personnel to wear protective gowns, hair and beard covers, hoods, overshoes, and gloves. In the cleanest environments, personnel all the aforementioned clothing as cleanroom apparel is extremely important in controlling micro-contamination to contain the particles emitted by people.

We undertake the Following Cleanroom Validation Services:

  • Airborne Particulate Testing
  • Air Change Rate Calculations (ACR)
  • Air Volume Flow Rates
  • Differential Pressure Measurements
  • HEPA Filter Integrity Leak Testing – DOP Method
  • Temperature, Humidity, Light and Noise Level readings
  • Recovery Performance testing
  • Airflow Visualisation tests, supported by a full written report
  • We also provide temperature mapping of rooms and storage facilities, in order to meet customers regulatory and QA requirements.

CLEAN ROOM VALIDATION SERVICES

CLEAN ROOM VALIDATION SERVICES

It is vitally important that cleanroom validation is an essential part of ensuring that cleanroom facilities are operating at the levels of cleanliness required by facility owners, their customers and where required perhaps external regulatory bodies.

However, there are multiple standards for clean room performance; in addition, facility owners can specify variations from the main classes of cleanroom to meet the needs of specific applications.

The Purpose of Clean Room Validation
Cleanroom validation or cleanroom certification can be seen as “passing a cleanroom test”; thus allowing the facility to continue to operate and be productive as designed. In most instances cleanroom validation is really about quality control, for instance:

  1. Preventing external contamination of samples by ensuring reliable test or experimental results.
  2. Ensuring a clean sterile environment for pharmaceutical or food production.
  3. Ensuring a low particulate environment to preventing damage to sensitive electronics.

For many facilities a cleanroom is the top of the critical asset chain; therefore, cleanroom compliance is also business critical factor; not just for profitability but also business reputation which is just as important.

Cleanroom Validation Services

APT Cleanroom Testing is a specialist clean room services company and we fully understand the importance of not just undertaking the validation testing and commissioning, but in helping facility stakeholders maintain high ongoing levels of cleanliness.

For APT Cleanroom Testing ongoing clean room validation is therefore part of a much wider process of ongoing monitoring, testing and maintenance.

Facility managers have to weigh up the costs of maintaining a higher grade of cleanroom against the costs of having to repair or replace a contaminated product; however they also have to attain the cleanroom ISO standard and regulatory requirements. It is critical that any judgement is carefully made, so that the agreed standards that have been decided sand agreed are rigidly enforced and validated, it’s worth noting that even small drops in quality may lead to an increase in contamination which may affect the bottom line and set experimental programmes/production by back by months.
