FUME CUPBOARD TESTING METHODS

FUME CUPBOARD TESTING METHODS

FUME CUPBOARD TESTING METHODS
APT Cleanroom Testing offer a wide range of testing services to meet the needs of our clients across all cleanroom industries from automotive to Nano Production. For every test we will issue a comprehensive test report. This will include the fume cupboard identification number, the date of the test, the type of test that has been carried out, the general room conditions at the time of the test, the results of our inspection and of the performance test, and any remedial actions that were needed or are required to meet the required standards.

The type of Fume Cupboard Testing may include: 

Containment testing using tracer gas

We provide a quantitative measure of fume cupboard containment under normal working conditions. We undertake containment testing using tracer gas analyses the escape routes of sulphur hexafluoride (the gas tracer) from within the fume cupboard. This type of testing is particularly recommended for newly installed equipment and following any major repairs as its highlights any weaknesses in the fume cupboard envelope. 

Face velocity measurements

We measuring the average rate at which air is drawn through the opening of the fume cupboard, face velocity measurements are the conventional method for measuring fume cupboard performance. This does not measure the containment ability of the fume cupboard which is undertaken using tracer gas.

APT Clean Room LEV Testing Service

Other Cleanroom Testing Services

APT Clean Room Testing also carries out Air Change Rates for your facilities, in accordance with the Orange Guide and the current ISO standards. In the event of contamination it is important for customers to know that the air will be changed in accordance with site and regulatory requirements to remove the contamination in an expedient manner. Our proactive testing and clear and concise reportage help our customers and stakeholders quickly identify the performance of their cleanroom facility in this respect.

We can also undertake Airborne Particulate Cleanliness Counts (Particle Counts). These are performed in accordance with each client’s facility classification, whether it is to an ISO or GMP standard. We use state of the latest calibrated Particle Counters that are regularly serviced and calibrated to ensure optimum performance.

HEPA Filter testing is carried out using the industry standard DOP method, whereby each filter is subjected to an upstream aerosol challenge; the downstream side of the filter is scanned with a photometer to identify the presence of any leaks. It is also important to ensure that each filter has been installed correctly and the filter frame and its housing are also thoroughly checked.

Our engineers have lots of experience across numerous industries from automotive to medical and all our data is produced and recorded record in a clear, concise and comprehensive Cleanroom Reports.

  1. Detailed method statements explaining how each validation test is performed
  2. Detailed records of measurements recorded during the validation visit
  3. Copies of calibration certificates for all test equipment used
  4. Original print-outs from particle counters (where relevant)

We undertake the Cleanroom Validation Services:

  • Air Change Rate Calculations (ACR)
  • Air Volume Flow Rates
  • Airborne Particulate Cleanliness Counts
  • Differential Pressure Measurements
  • HEPA Filter Integrity Leak Testing – DOP Method
