Specific Requirement for Calibration - ISO 17025 Clause 5.6.2 Interpretations

[midhun926]

Thank you for you reply....Actually i am amazed when i get quick and precise reply for my question....This forum is fabulous. Now it is 9 'o' clock in the morning and i have just started my work. Today i have come up with a different clause
ISO 17025: clause no;5.6.3.4
It says "The the laboratory shall have procedures and policies for safe handling , transportation,, storeage and proper use of its reference standard and reference material in order to prevent contamination and deterioration and in order to protect their integrity."

But my question is stale.
Q1
what is the difference between reference standard and reference material? can any body help me by givng an example, as i feel it is litle bit confusing ...i had asked this question earlier.

Q2. ISO 9513....is it a reference standard...if not what could be the term used to call it?.....and if it is a reference standard,what does the above mentioned clause mean by necessity of calibrating a standard.

I need some clarificaton on ISO:17025 clause 5.6.2.1(specific requirement for calibration)
1. It says " a calibration laboratory estabilishes traceability of its own measurement standards and measurement instruments to the SI systems by means of unbroken chain of calibrations and comparisons linking them to relevent prymary standards of SI units of measurements"

"

To keep it simple, we have stated in our quality manual that all physical standards such as mass pieces and thermometers are to be calibrated / validated by ISO 17025 accredited facilities. As the calibration facility is 17025 accredited, the assumption is that their references are traceable to national or international standards.

The same is applied when validating analytical balances. the work is carried out by 17025 accredited service providers.

Can I join in with clarifying one other clause in ISO 17025 too? Calibration certificates, Section 5.10.2 (k), 'where relevant, a statement to the effect that the results relate only to the items tested or calibrated'. Question: - Isn't this obvious from having satisfied 5.10.2 (f)??

Thanks in advance & sorry if I've asked this in the wrong place.

.....If my knowledge serves me better, 5.10.f says only about the description condition and identification of a particulat sample ..if your customer send you a sample for testing( assume that you dont know their sampling procedure or how that sample is drawn) and you have tested that sample and found that the sample is of required quality.Then you can mention in the respective test report that the above sample is found to be good. That is what 5.10.f says..........................since you( or your person) have not done sampling, you cannot say that the test report holds for all the samples of that particular batch from which the tested sample is taken. So here 5.10.k comes to help you.....it says that you can tell your customer( that is, you can mention in the calibration report) that the result only holds for the sample that you have tested and is not applicable to the other samples in the batch...So, in future, if any of the sample in the batch fails to hold the quality, you will not be responsible.....
