4.2 For Color – Cleaned Spatula, sampling bottle.

5.0 SAMPLING PLAN

5.1 For Noodles, Soda Ash, and Frisis – Composite samples have to be prepared after collecting samples from 5% of the total nos of bags.

5.2 For other raw materials, Composite samples have to be prepared after collecting samples from √n+1 nos of the container. (If no. of the container is more than 5).

5.3 Composite sample has to be prepared after collecting a sample from all the containers equal to 5(if no. of containers less than 5).

6.0 MAKING-OF SAMPLE
