Cleanrooms
Customised Testing
Cleanroom testing is dictated largely by the purpose for which the cleanroom is used. The following standard testing performed by Total Air Care can be taken as a guide where no testing and maintenance procedures are prescribed. Total Air Care will readily adapt its standard test procedure by removing some of the tests or adding some of the optional tests to produce a customised test procedure for a particular facility.
Standard Service
The standard annual service offered includes the following:
1. Testing Essential Performance Requirements
AS1386, the Australian standard for cleanrooms and clean workstations requires certification of the cleanroom at least every 12 months and recommends regular maintenance every 3 months. Total Air Care Laboratory provides annual testing and certification using Australian standard test methods to ensure that a cleanroom is performing within the essential performance requirements of the applicable standards.
The essential annual tests performed are as follows:
For Laminar Flow Cleanrooms:
- Determination of air velocity and uniformity by AS 1807.3 test method.
- Determination of work zone integrity by AS 1807.5 test method.
- Determination of integrity of terminally mounted HEPA installations by AS 1807.6.
- Measurement of air cleanness with a particle counter by AS 1807.8.
- Determination of air pressure differentials by AS 1807.10.
For Non-laminar Flow Cleanrooms - Class 350 and Cleaner:
- Determination of integrity of terminally mounted HEPA installations by AS 1807.6.
- Measurement of air cleanness with a particle counter by AS 1807.8.
- Determination of air pressure differentials by AS 1807.10.
- Determination of air changes per hour.
For Non-laminar Flow Cleanrooms - Class 3500:
- Measurement of air cleanness with a particle counter by AS 1807.8.
- Determination of air pressure differentials by AS 1807.10.
- Determination of air changes per hour.
2. Immediate Communication of Problems
The test technician will communicate information regarding any problem associated with the cleanroom immediately following testing or as soon as possible.
3. Endorsed Test Report
A detailed report on each HEPA filter and each cleanroom and anteroom tested will usually be completed and mailed within 5 working days of completing the testing. The test report lists all the tests performed and the results obtained. Test reports show clearly the laboratory’s accreditation by International Accreditation New Zealand.
4. Endorsed Certificate of Compliance
A certificate of compliance is mailed with the test report.
5. Courteous and Professional Service
You can expect our test laboratory staff to conduct themselves in a courteous and professional manner. If you have any complaints please advise us so we can take corrective action.
6. Validation Reminder
Your cleanroom details will be loaded into our computer data base and we will automatically contact you before your facility becomes due for the next validation.
Optional Services
A number of other tests may be applicable or desirable depending on the purpose of the cleanroom. The following tests are common.
- Performance of laminar flow cleanrooms under loaded filter conditions - AS 1807.4
- Integrity of HEPA filter installations not terminally mounted - AS 1807.7
- Air flow parallelism - AS 1807.11
- Sound Level – AS 1807.16
- Illuminance – AS1807.15
- Work zone temperature - AS 1807.12
- Relative humidity - AS 1807.13
- Vibration - AS 1807.17
- Recovery time - AS 1807.24
Maintenance
Total Air Care technicians are skilled in balancing cleanrooms and detecting and repairing system leaks. Often this can be done at the time of the testing to minimise costs.
Total Air Care carries most filters and a range of fans in stock so we can provide fast and efficient service to minimise cleanroom downtime.
Abbreviated Quarterly Testing
A reduced 3 monthly test is designed as an input to the regular maintenance recommended by AS 1386 and may be required by Good Manufacturing Practice.
The standard quarterly testing includes abbreviated air cleanness testing with a particle counter and a check of the air pressure differentials.
