ISO 17025 audit

I have a very barebones understanding of what an audit needs to cover but I lack the experience of knowing how to conduct an audit.

For example, I know that an ISO 17025 audit needs to look for up to date equipment calibrations, but I do not know the reference guidelines set out in ISO 17025 (clause 7.4 I believe) for this and what would need to be presented as evidence, how to get this evidence or from who.

In other words I know "what" to look out for, but not "how" to or "who" to.

Risks to Impartiality

I'm the Quality Manager at a testing lab, and I'm working on a training presentation for staff on 'risks to impartiality'. I will be asking them to report any identified risks to their supervisor and one of the examples of a risk to impartiality I'm giving as one that is likely to occur is 'pressure on lab staff due to an unforeseen event (e.g. equipment failure, delay in receiving supplies etc.) I believe that these are risks to impartiality as they do put the staff under stress which can lead to cutting corners if they aren't properly mitigated. I'm just wondering if I'm correct or if these types of pressures are not exactly what is meant by risks to impartiality. If they are considered risks, is there a good way to communicate these? I feel like these ones are not what most expect as a risk to impartiality as most think of Conflicts of Interest. Thanks for any information you can provide.

Is proficiency testing required when using outside lab?

Is it required that proficiency testing be completed using an outside lab? If the SME, for instance, verifies their performance with an outside lab, then we have the SME run a test side by side with each technician, can we document that as their proof of proficiency/competency?

Merging ISO 9001 & ISO 17025

How can we merge ISO 9001 & ISO 17025? If we already have ISO 9001 system and  want to implement ISO 17025 and have already quality manual for ISO 17025, should we select clause 8 option B in ISO 17025 for the responsible of ISO 9001 system

Implemention of ISO 17025

Hi, l have a question for the expert  if we implemet ISO 9001 and now we need to  implement    the ISO 17025 
How we merge the two system in records and procedures and we have to point it out  in the quality manual , or every system ISO 9001 and ISO 17025  should be separate in their  records and procedures .
The second question :  we want to participate in PT ,Profechency Test  in food analysis ,cosmetic ,detergents , paints ,lubricants oil  , textile, leathers, paper , construcure analysis field , could you recommend  some of PT service  providers . 
The third  question could I see a simplified way to write a plan to implement the international standard ISO 17025 
The fourf question : If a new employee occupies a quality manager, should it be within his plan to make sure that the work in the laboratory is done correctly and to follow up to what extent the previous quality manager applied the requirements of ISO 17025 to know what has been achieved and what needs to be completed, or works directly on preparation for proficiency tests According to the administration's request, and this is specified in his plan. I apologize for the many questions, but I cherish the advice provided by you.

Evaluation of the calibration uncertainties

In the calculation of regression uncertainty, the information I have access to says "Sa/Sb - If value is too high for validation criteria use more standards close to blank".  
My question is and I can't seem to find any info on this - what is considered too high and/or what do you look at to 'determine' this?

Question about pH meter

Hi, we have  pH meter *** and we need to use flouride  ion selective electrode  by using  the ***  ,  could  you provide us flouride  calibration method  or procedure and how to setup the electrode ,that because when I caibrated the flouride  ion selective electrode meter ,after calibratiin the meter gave  me  a wrong value for the reference stanadard  , even when  I used  one of  the standard which was used in calibration .
