Sample size and Sample Qty

793 Views

Hi friends ,

I ahve created a Sampling Procedure with followig data :

Sampling type = SAmple %

Valuatio mode = manual

Inspection Points :-

Sample mgmt activated .

In the sample size I have mentioned 2% .

Now , I have created a sample drawing Procedure with following data :

No of Primary samples , acc to formulae = root(lot size) + 1

No of Pooled SAmples , fixed = 1 .

I have attached above SDP in inspeciton plan header with inspection point 200 and the SAmpling procedure to the MIC in plan .

On creating a lot of 100 Litres , I got following :

No of physical samples generated = 12 ( 11 primary and 1 pooled )

In Primary physical sample , :

Sample Qty = .545 Litres and Sample Size = 6L .

and for Pooled physical sample :

Sample Qty = 2 Litres and Sample Size = 6L .

In RR , I am getting this screen :

My doubt is :

1. from where sample qty and sample size in physical sample is being calculated

2. why these qty are different in pooled and physical sample .

3. What thing determine the 2 lines for same MIC in RR .

Please specify clearly as I am new to QM . Thanx in advance

Regards
