Assembling of the test apparatus: Connect the needle valve (f) to the steam service pipe as shown in Figure No.1. Assemble the apparatus so that condensate will drain freely from the long rubber (i) tube into the glass sampling pipe (e) with U type end as shown in Figure No 1. Fill the container (d) with cold water until it overflows. Fill the burette (a) and funnel (b) with cold water, invert them and place them in the container (d). Draw out any air that has collected in the burette. While keeping the steam sampling pipe (e) out of the container, open the needle valve and allow steam to purge the air form the pipe. Place the pipe in the container, locate the end within the funnel, and add more cold water until it flows through the overflow pipe (k). Place the empty measuring cylinder (g) under the container overflow. Adjust the needle valve to allow a continuous sample of steam into the funnel sufficient to cause a small amount of Steam Hammer to be heard. Ensure that all the steam is discharged into the funnel and does not bubble out into the container. Note the setting of the needle valve. Close the valve. Place a thermometer (j) to dip the tip in the water of container. Ensure that the container is topped up with cold water and that the measuring cylinder is empty. Draw out any air present in the burette. Note the Burette reading. Testing:

Ensure that the sterilizer chamber is empty except for the usual chamber furniture. Select and start the operating cycle. When the steam supply to the chamber first opens, open the needle valve (f) to the previously noted setting, allowing a continuous sample of steam into the funnel sufficient to cause a small amount of steam hammer to be heard. Allow the steam sample to condense in the funnel. Any non-condensable gases will rise to the top of the burette. Overspill formed by the condensate and the water displaced by the gases will collect in the measuring cylinder. When the temperature of the water in the container reaches 70-75C close the needle valve. Note the reading of the Burette. Note the volume of gas collected in the burette (Vb) as difference between initial and final reading and the volume of water collected in the measuring cylinder (Vc). Calculate the fraction of non-condensable gases as a percentage as follows. Fraction of non-condensable gases = 100 x (V b/V c). Note: Carry out the three tests in three different days.

If the results of the three tests differ significantly, then the cause should be investigated before proceeding further.

The minimum F0 value {by equation (1)} should be more than the biological F0 for the biological indicator strip exposed for the biochallenge study. The biological F0 value for biological indicator strip exposed during the sterilization can be calculated as follows. F0 = D121 ( log A log B) ..

Keep the spore strips along with temperature probes. After completion of sterilization cycle, cut and open the exposed indicator under LAF, by using sterile forceps and scissors and inoculate it in a test tube containing 30 ml of Soybean casein digest medium ( SCDM). Incubate test tubes at 55 - 600C for 7 days. Keep a blank tube of SCDM as negative (-ve) control. Inoculate an unexposed biological indicator in SCDM tube as Positive (+ ve) control. Observe for any growth in the tubes on each day starting from 1st day. Record the observations on daily basis as given in data sheet. Observations & Results Record the observations in the prescribed format and enclose reports in Validation Report. Study the sterilization cycle duration with in the load with respect to chamber sterilization cycle. Action To Be Taken In Case of Failure: If minimum sterilization temperature of 121C is not achieved in one or more location(s) during sterilization hold period of Empty Chamber Heat distribution cycle following action are taken: Engineering department will be informed to check the calibration of instruments like temperature indicating probe, Digital temperature indicator, Data logger, etc. However all the instruments are checked for calibration before validation hence engineering departments will be asked to send the reference instruments for re-calibration to Calibration agencies. If fault is found due to error in calibration Steam Sterilization cycles will be repeated. Engineering department will check mechanical operation of pneumatic valves, operation of vacuum system, functioning of steam trap, steam supply in jacket, any blockage in the steam or vacuum line, any leakage through door gasket and other joints. If fault is found due to mechanical error, cycle will be repeated putting 2 probes in the location of lower temperature.

If minimum sterilization temperature of 121C is not achieved in one or more location(s) during sterilization hold period of Loaded Chamber Heat Penetration cycle following actions are taken If the failure occurred with the cycle of media it will be considered as critical failure as media used for all microbiological testing (e.g. sterility testing), so there is a chance to false interpretation of results. If the failure occurred with the cycles of garments it will be considered as Major failure because it may hamper the environmental conditions of sterility testing area. If failure occurred with the cycles of SS buckets it will be considered as Minor failure because SS containers are used for sanitization purpose only. In case of any failures, cause of failure will be investigated in detail as given below. a) Action to be taken in case of critical failure: If any probe located inside the media shows the temperature below 121C, Fo value of the location and Biological Indicator test data will be reviewed. If Fo value is lower than the accepted limit and biological indicator test report shows acceptable reduction in the bacterial population, then the cycle will be repeated and the investigation will be carried out to determine attaining the minimum required temperature. In case the biological indicator also shows positive growth, investigate the cause of failure and review the following parameters: Sterilization parameters Loading pattern Biological indicator qualification Necessary corrective actions will be taken to rectify the known (or identified) defect and a revalidation of the sterilization cycle will be undertaken before commencement. b) Action to be taken in case of major failure: Checked By P.

If any probe located inside the load of Garment shows the temperature below 121C, data of Fo value of the location and Biological Indicator test data will be reviewed. If Fo value is lower than the accepted limit and biological indicator test report show required reduction in the bacterial population then the cycle will be repeated and the investigation will be carried out to determine the cause of not attaining the minimum required temperature. In case the biological indicator shows positive growth, the personnel monitoring data and environmental monitoring data and garment sterilization records of the batches manufactured since last re-validation will be reviewed. If the data and sterilization record is well within the acceptable limits and cycle will be repeated to establish the sterilization parameters. c) Action to be taken in case of minor failure: If any probe located inside the load of SS buckets shows the temperature below 121C, data of Fo value of the location and Biological Indicator test data will be reviewed. If Fo value is lower than the accepted limit and biological indicator test report show required reduction in the bacterial population then the cycle will be repeated and the investigation will be carried out to determine the cause of not attaining the minimum required temperature. In case the biological indicator shows positive growth, the cycle will be revalidated for reestablishment of sterilization parameters. 6.10.8 6.10.8.1 FREQUENCY OF REVALIDATION: REVALIDATION SCHEDULE: STUDY VALIDATION FREQUENCY
