Hi, TEST METHOD VALIDATION is completly new topic for me.
According to that, my question is:
Is MSA (MSA1, MSA2, MSA3 and linearity) a good solution for confirming the compliance of the first method?
If yes, what about non-replicable study, for example: Test of bags heat seal strength on...
acceptance p-value for linearity and bias tests in minitab results.
can I get to know the acceptance p-values for bias and linearity in minitab results. in most of documents it says that if p>0.05 for constant of linearity results; it says that measurement systm not linear. and if p>0.05 bias of...
HI all,
Can someone help me with the FILE recommended by AIAG MSA 4ed for LINEARITY?
We have the original book bought several years ago, but when I arrived to the company I never saw any CD or files, so I am not sure how it should arrived with the book MSA.
Can someone kindly share the Linearity...
...ISO 22514-7 and I have a question about using the MPE value to calculate the capability of the measurement system instead of performing a linearity and type-1 study.

I'm trying to find stated MPE values in calibration reports. In a calibration report for a CMM the...
Hello,
I am not a calibration/MSA person and I have what may be a few basic questions regarding MSA. How do you determine if a gage is linear or non-liners? Can linearity studies be done on non-linear gages (CMM's, vision systems, etc...)?
Thanks in advance for any input.
Dear all,
Can you please explain what is the purpose of calculating Ta, Tb & R Square in linearity study & how to conclude the study by seeing the Graphical analysis chart. I could not able to understand this calculation. Please help me.
Hi everybody,
I want to create the same report than minitab for linearity and bias study. As showed in picture attached.You could also find my excel file.
As you can see, I am blocked with calculation of P-value for biais and linearity.
Thank you for your help.

The customer request to conduct bias, linearity and stability for the special characteristic. I conduct bias, linearity and stability study by using production part. I use the part as master and pick 3 measurement as master and periodically measure the same part and compare to the master. Is...
Hi,
Anyone can guide me !!!
I'm going to do MSA study for all our company's caliper and Micrometers.
Already I done GRR study , Please help me to advice weather bias, lenearity & Stablity are can we apply in those equips..
If can what is the spec we hv to follow for evaluate that equip...
I have a question about bias and linearity studies which I hope you guys can help me with.
I recently performed a Bias and Linearity studies on a tool. We are measuring a film thickness on a substrate. The NIST traceable standard used for the Bias study is 45A +/- 4A (A=Angstroms).
When I...
My company took a finding in a recent TS audit for not performing bias, stability and linearity studies. TS para 7.6.1 defers to customer manuals for which methods to use, and none of my customer supplier manuals mandates any of these 3 methods. We have never been required to submit such...
...What is the common interval for measurements for a flat micrometer that has 6 months calibration interval with no problem in past?
3.Linearity: Gage Blocks or real parts?
AIAG MSA: Due to process variation, select 5 parts that covers the entire operating range of the gage. What is process...
Hi all – I am hoping for some guidance,
Once you have answered the question of linearity, I am stumbling on how to "properly" apply it.
We have performed Gage Rr studies on the bulk of our existing lab methods and have worked to improve processes and procedures until we were happy with the...
Hello Everyone,
I am currently creating a Stability, Bias and Linearity spreadsheet for some method validation work I am doing in the lab. Creating the stabilty and bias portion were quite simple; however, the linearity portion gave me some trouble. I have been using the raw data from...
Hello All,
I am new in this forum and I am not familiar with MSA studies but I am interested in it. I've performed gage linearity and bias study but I am wondering how to interpret the result I have from this study. Result are in attachment. I will be very thankful if somebody help with...
...by this value ?
2) I have a measuring instrument that I wish to make an analysis of this measurement system MSA (Gage R&R study + Gage Linearity and Bias Study) to verify its performance.
This instrument is inserted into the production line and does the measurement of 4 types (A,B,C,D)...
Hi
Does any one know how to calculate the P value for the Average Bias.
and what is the formula? it is an output from minitab.
Gage Bias
Reference Bias P
Average 0.157333 0.000
2 0.170833 0.000
4 0.158333 0.000
6...
Hi Everyone,
Does anyone have excel samples of MSA Bias, Linearity and Stability file with formulas? I need it for my project
Thanks and Regards,
Alagappan
Hello. :bigwave:
I work in a company that assembles PCB with SMD and PTH components. I've read a lot of materials about MSA (gage R&R, linearity and bias), but in all I find the "classic example" of measurements made by operators in parts (for instance, measurementes of parts with caliper by...
