Repeatabilty + Reproducibility (Gage R&R) Study - Inter-Laboratory Study (ILS)

Hello everyone,

I would to firstly thank everyone behind the creation of these forums, loads of information is available and I hope to benefit from it.

I am currently doing my masters in civil engineering at uni. We are investigating a test method which produces unpredicatable and significantly variable results.

An inter-laboratory study has been suggested. I am following the ASTM E691 standard "Standard practice for conducting an interlaboratory study to determine precision of a test method", however I have not had luck finding the software that is used along with this standard. It is mentioned in the standard that the calculation is carried out using software provided by ASTM (which I dont have).

I am wondering whether any of you would have an excel template which would help me analyse the inter-lab test study in an efficient manner?

I looked around the forums and have found a few Type 1 gage R&R study threads, are these the same to what I am doing? The attachments were however all removed due to some copyright infringement?

Any help would be greatly appreciated!

P.S Merry Christmas and a happy new year to all!

Kind Regards,

Amin

Re: Repeatabilty + Reproducibility (Gage R&R) Study - Excel Template needed

As a quickie, have you looked at the file attachments? Gage templates.

Re: Repeatabilty + Reproducibility (Gage R&R) Study - Interlaboratory Study

Thanks for that Marc,

I have actually looked through the attachment list and have no found something that is suitable.

The repeatability and reproducibility study that I will be carrying out is not binary data based (ie not pass/fail) it depends on achieving numerial data (such as dry density of a material) and then trying to find whether the test is repeatable or reproducible based on the statistical analysis of that data?

It works by calculating the standard deviation of repeatbility and reproducibility (among other things).


Thanks for your help :)
