SOP FOR SIEVE INTEGRITY TEST

1. OBJECTIVE

            To lay down the procedure for sieve integrity test.

• SCOPE

      This SOP is applicable for sieve integrity test in Production Department.

       RESPONSIBILITY

           Production Chemist & operator      : To follow the procedure

      ACCOUNTABILTY:

QA & Head Production                  : For system compliance

•       PROCEDURE
  • To ensure the sieves are checked as per defined procedure.
  • To ensure proper numbering of the sieves.
  • All sieves should be checked visually by the operator / Manufacturing chemist, against a uniformly white or black background for any defect, blinding or contamination, before and after use and details shall be recorded.
  • The visual checks should identify any damage, scoring, blinding or contamination, likely to affect the performance of the sieve.
  • It is important that the condition of the molded edges of the sieves should be checked.
  • Damaged wires or any part that comes under powder should be checked.
  • Gaps in loosened or slackened wire mesh should be checked
  • Rusting of wires should be checked
  • QA chemist should verify the details and enter the observations in BPCR.

• Sieve MaintenanceSieves should not be overloaded during screening as it leads to sagging of the wire mesh, distortion of aperture sizes & tearing of the screen.
• Sharp or blunt metallic objects should not be used on the screen surface.
• Application of downward pressure by a gloved hand should be avoided as it leads to over sizes passing through & sagging of the sieve.
• Care should be taken while cleaning the wire mesh as hard scrubbing will lead to distorted apertures & screen damage.
  • Note: Always use the hand gloves during handling of sieves.
