Name of Material :
Material code No :
A.R. No :
Sampled by : Date :
Container No : of :
Sampled Qty :
5.7.2 Prepare and send the sample withdrawal slip to Raw material store for quantity of material to be sampled.
5.7.3 Ensure that containers are cleaned externally, before bringing the container to be sampled to the sampling area.
5.7.4 Check the details given on the Material Receiving Report with the suppliers label and the label affixed by the stores on all 100 % raw material containers.
5.7.5 Check whether the material falls under Approved vendor list.
5.7.6 If the material is not from approved vendor, then the material is not to be sampled.
5.7.7 Any discrepancy found should be immediately brought to the notice of the store incharge and Q.C. Executive/Manager.
5.8 Damaged containers
5.8.1 Check the physical condition and cleanliness of raw material containers before opening for sampling.
5.8.2 If any container found in damaged condition, intimate Raw material store incharge to make separate MRR.
5.8.3 Damaged containers whose integrity is doubtful should be sampled and tested separately with a separate A.R.No.
5.9 Gowning procedure
5.9.1 Wear fresh gown before entering into sampling area.
5.9.2 Cover the hands with gloves and wear a cap and mask to cover hair and nose respectively.
5.9.3 Cover the footwear with shoe cover .
5.9.4 Use separate apron, nose mask, Hand gloves, cap & shoe covers for sampling of different material.
5.9.4 Mop the hands with 70% IPA and air dry before proceeding for sampling and particularly when samples are to be drawn for Microbiological testing.
5.10.1 Before proceeding for sampling ensure:
• Cleaned’ status for the sampling area
• Availability of ‘Ready for use’ suitable sampling device
• Removal of all previous raw material containers and used utensils.
5.10.2 Label the sample bag or container properly & keep it ready. Arrange the raw material containers which are to be sampled in sampling booth area.
5.10.3 Note down the differential pressure reading of sampling booth and other respective detail in sampling checklist.
5.10.4 Open the container for sampling one by one.
5.10.5 Observe visually for appearance of the material for any gross abnormalities like decolourization, lumps, non-characteristics odour, foreign matter and physical heterogeneity.

5.10.16 For active raw material prepare composite sample for every 10 containers of the consignment by taking equal quantity of material from individual sample container. Mix thoroughly with spoon in big plastic bag to make sample for assay test. For complete analysis and retain sample make composite sample by taking equal quantity from all bags.
5.10.17 If specified in the Annexure-I, take the composite sample for microbiological analysis in sterile container.
5.10.18 Ensure the sample containers are closed tightly and labelled properly.
5.10.19 Handover the samples along with MRR, stores physical verification report, sampling checklist and supplier’s COA (IF received) to Q.C. department for analysis.
5.10.20 If the party’s COA is not received, inform to Purchase Department.
5.10.21 Keep the retain sample and sample to be analysed at specified storage condition as per SOP.
5.10.22 Mark ‘SAMPLED’ stamps on containers from which the samples are collected. Cross the original approval label of manufacturer on all the containers.
5.10.23 Affix yellow colour duly filled & signed “UNDER TEST’’ label on each container below white label of store.
5.10.24 Prepare sampling record of raw material.
5.10.25 Make the entry of sampling done in sampler booth log card with respective details.
6.1 COA = Certificate of Analysis.
6.2 Q.C. = Quality Control
6.3 No. = Number
6.4 Mfg. date = Manufacturing date
6.5 Exp. Date = Expiry date
6.6 MRR = Material Receiving Report
6.7 UT = Under Test
