for tablets

20 tabletsCheck for defects like surface finish, lamination, mottling, chipping and swelling powder on the tablets embossing (if any), picking, capping and sticking. The appearance of the tablets should comply with that mentioned in the individual specification.
2.Average Weight20 tabletsWeigh individually all tablets, calculate the average weight.
Weight variation

(For tablets)

20 tabletsWeigh one by one 20 tablets and determine the weight variation by subtracting the individual weight of tablets with average weight of each tablets.
3.Disintegration

time testing for tablets

6 tabletsOperate the disintegration tester as per SOP. Place 1 dosage unit in each of the six tube of the basket and, if prescribed add a disk. Operate the apparatus, using water or the specified medium as the immersion fluid, maintain temperature at 37+2ºC or given in specification. At the end of the time limit specified, lift the basket from the fluid, and observed the tablets. All of the tablets have disintegrated completely. If 1or 2 tablets fail to disintegrate completely, repeat the test on 12 additional tablets. The requirement is met if not less than 16 of the total of 18 tablets are disintegrated.
4.Hardness

Testing

6 tabletsHardness test shall be performed with the help of tablet hardness tester as per SOP number _____________
5.Thickness testing for compressed/ coated tablets6 tabletsThickness shall be determined using vernier caliper/ digital tablet hardness tester as per SOP number _________.
6.Friability testTablets with a unit mass equal to or less than 650 mg, take a sample of Whole Tablets Corresponding to 6.5 g. For Tablets with a Unit mass of More Than 650 mg, take a sample of 10 Whole Tablets.The tablets should be Carefully de-dusted prior to testing. Accurately weigh the tablets sample, and place the tablets in the drum. Rotate the drum 100 times, and remove the tablets. Remove any loose dust from the tablets and accurately weigh.

Operate friability test apparatus as per SOP number ­­­­__________

7.Weight gain of coated tablets100 tabletsTake weight of 100 pre warmed tablets and Weigh the 100 coated tablets. Calculate the weight gain.
8.Appearance /

16.Bottle CleanlinessTwo bottles/JarVisually check the bottles/Jar for their cleanliness
17.Overprinting detailsRandom samplingVisually check the blister, strips, carton, label for batch details, wrinkles, proper pasting, appearance, etc.
18.LabelingRandom samplingVisually check the labeling for any defects like Wrinkles/ crumpled/ slanted/ stained or any other abnormal observations.
19.Leaflet PlacementTwo bottles/jarsVisually check whether the leaflet is placed correctly on the bottle cap/ inside the cartons.(as applicable)
20.Measuring Cup PlacementTwo bottlesVisually check whether the Measuring Cup is placed correctly on the bottle.
21.Tests to be conducted during blister and strip packingRandom samplingVisually check for any punctures, empty pocket, overprinting details, sealing quality, knurling quality, forming quality, sealing and forming plate and roller temperature.
22.Carton packingRandom samplingVisually check for the correct coding, Product details, and weight of the Carton.
23.Tests to be conducted during shipper packingRandom samplingVisually check for the correct coding, number of unit packed, proper BOPP taping, shipper number and weight of the shipper.
24.Metal detector challenge testFerrous non-ferrous and S.S. blocks.Pass ferrous non-ferrous and S.S. blocks through metal detector. Check the blocks whether it is rejected.
