5.0   Procedure for Operation of Sieve Shaker:

    • General Procedures

    • In case of noticing any malfunctioning of the instrument, follow SOP on Maintenance of Laboratory Instrument.
    • Follow the SOP on Instrument/Equipment usage logbook, for the entry of usage of the instrument. 
    • Preparation of internal and external (Third Party) Calibration schedule and calibration practices. 
    • The operational procedure of Sieve Shaker

    • Place the sieve shaker in a flat surface preferably on a rubber sheet.
    • Use certified sieves.
    • Select the sieves required as per monograph/procedure.
    • Check the integrity of the sieves.
    • Ensure the sieve numbers are matching with the ASTM number given on the sieves.
    • Place the sieves in the descending order of sieve No. on the collecting pan.
    • Adjust the required time as per individual monograph using the time UP/DOWN key on the front panel.
    • Adjust the power using the power UP/DOWN key on the front panel.
    • To select Continuous or Intermittent sieve shaking push respective keys on the front panel.
    • Weigh the sample and evenly spread the same on the top sieve and close the sieve.
    • Place the sieve sets on the base of the holder firmly and lift the assembly to touch the top of the holder.
    • Tight the assembly and switch on the mains.
    • Then press the START key to start the operation.
    • After completion of the process carefully remove the sieves set.
    • Collect the samples retained on each sieve and on the collection pan and weigh the quantity of sample retained on each sieve.
    • Calculate the percentage of the sample retained on each sieve and report.
    • Check the integrity of the sieves again, If not OK label it as rejected and discard the same as scrap.
    • Clean the sieves with water and dry.
    • Ensure the holes of the sieves are not blocked.
    • Store in a separate place.
    • Use the sieves having the same diameter so that they will fit best in the assembly.
    • Timer calibration is done by External agency every year.
