Sample Size for Incoming (Receiving) Materials and Parts

I have been tasked with finding the sample size of incoming materials

I would like to make the process robust enough to change as we gain or loose confidence in the suppliers.

Here is an example

Supplier X has supplied us with 250 parts requiring inspection. based on the confidence we have in the supplier how can find the sample size?

Be gentle, I am new.

Re: Sample size for incoming materials

Hello first time poster,

I am posting to encourage others. You have come to the right place! The time is late in the business day, and just before Thanks-giving, so comments might slow down. There are software packages mentioned frequently like Minitab, for analysis, and your specific requirements are needed to assist in refining an answer. I am sure there are many threads already answering your question in general. Your specifics will require DATA. Some links within Elsmar Cove can be found by pressing the [Search] button, and looking for the subject matter.
Using the [Search] feature button, and looking for "incoming material sample size", I found this @

Lots and lots of threads to read.

Hi,
Get yourself this standard "ISO 2859" there is all you need to know.
cheers

Attribute data or variables data?

Just to clarify, ISO 2859 is "Sampling procedures for inspection by attributes".

Marc is right.
ISO 2859-1 for inspection by attributes and ANSI/ASQZ1.9 and ISO 3951 for inspection by variables. :agree1:
good luck.
