Biological, medical industry transfer window test method
Biological, medical industry transfer window test methodThere are as many as 12 items that need to be inspected for the transfer window. This paper will describe the appearance inspection method, the performance inspection method, the nozzle inspection method, and the air exchange frequency inspection method. The following content is written in combination with production experience and biological and medical industry transfer window technical specifications.Visual inspection method The appearance quality is inspected by visual inspection. 1) Observe whether the shape of the cavity, supporting frame, disinfection device, outer cover, sterilization device, fan, transfer window door, and other components are normal, whether there is deformation, and whether there are strengthening measures in the connection part with the cavity. 2) Observe the number and position of ultraviolet lamps installed 3) Whether the cavity is clean and dust-free 4) Whether the switch and key operation are flexible and reliable. The parts are securely secured 5) Organic materials should not be used on the inner surface of the transfer window and liquid medicine transfer box with fumigation function. Performance test method Test methods for control systems 1) Use the control switch and operation panel to control the components of the device, and observe the working status of the components in manual mode and automatic mode respectively. 2) Start the controller timer, and start the stopwatch timer at the same time, when the controller timing ends, immediately stop the stopwatch timing, using formula (2) to calculate the error: X=(A-B)/A×100% Formula: X -- controller timer error; A -- The preset duration value of the controller timer, in seconds (s) B -- Duration value measured by stopwatch, in seconds (s) Nozzle wind speed test method (if any) Test according to JG/T 382. Use a hot ball anemometer to measure the air supply velocity at the center of each nozzle. During detection, the measuring point should be located at the center of the outlet plane of the nozzle, and the wind speed at the center of the nozzle is the arithmetic average of the wind speed reading measured at the center of the nozzle. Test method of air change number Test according to JG/T 382. Each air supply outlet is evenly divided into at least 12 squares or rectangles of the same area with each side length not more than 100mm, and the air supply velocity at the center of each square or rectangle is measured with a hot ball anemometer, and the arithmetic average of the wind speed at each measuring point is used as the average wind speed at the air supply outlet. The number of air changes is calculated by the following formula: n=vp×f×3600/V n -- the number of air changes, expressed in times per hour (times /h) Vp - average wind speed at the outlet or the center of the nozzle, in meters per second (m/s) f -- Total area of air supply outlet, in square meters (㎡) V -- Volume of air supply area of the transfer window, the unit is square meters (㎡) The above is the biological, medical industry transmission window test method. |
