Proficiency Test and Interlaboratory Variability Testing - Required?

[intrestedparty]

Dear All

Any one explain about the Proficiency test and the inter laboratory comparrision?

Is this is mandatory for ISO 17025 and ISO 15189?

We have numerious scope for accreditation, for each and every scope we need these Proficiency test and the inter laboratory comparrision?

What are the steps involved in this?

Any one kindly help in the topic?

Proficiency testing

Are these the test, normally called " the round Robin test " ?
In other words : Interlaboratory variability testing.

In ISO 17025 I found this:

5.9.1 The laboratory shall have quality control procedures for monitoring the validity of tests and calibrations undertaken.
The resulting data shall be recorded in such a way that trends are detectable and, where practicable, statistical techniques shall be applied to the reviewing of the results.
This monitoring shall be planned and reviewed and may include, but not be limited to, the following:
a) regular use of certified reference materials and/or internal quality control using secondary reference
materials;
b) participation in interlaboratory comparison or proficiency-testing programmes;

Not a firm requirement, but seen as a good way.
Hope this helps.

best regards,

Antoine

If you have a laboratory, if proficiency tests / inter-laboratory comparisons (PT/ILC) are available, then yes it is a requirement for accreditation under ISO/IEC 17025.

Your accrediting body, NABL, will be able to give you better guidance for your specific organization, based on the accreditation scope under 17025.

Hope this helps.

Interlaboratory variation testing

With all respect, but " Where is the shall ?"

Best regards,

The "shall" will come from your accrediting body.

In our case, we are required to send an up to date ILC/PT tracking form quarterly. We are required to participate in a minimum of two per year, although they suggest 25% of our scope.

Not all testing listed on your scope will require ILC/PT testing. If there is not a PT provider for your disciplines, you may do PT internally or with another lab of your choice, if their scope also contains those tests.

 

[Hershal]

Actually, the "Shall" comes from the MRA groups like ILAC, APLAC, EA, and NACLA....an accrediting body that does not require PT/ILC - WHERE IT EXISTS - can be denied recognition by the MRA (in other words, they will not be allowed to become a signatory), or if already in the MRA, the accrediting body can be suspended.

Hope this helps.

Proficiency Test

Dear all

We provide clean room testing for various scope and various methods, for this scope of testing and calibration , our accreditation body NABL does not have the proficiency test and no any other clean room lab is accredited (ISO 17025) for interlab comparrision. For this case what can we do?

I cant get clear information form NABL

Any body kindly help in this issue, and kindly refer the procedure for Proficiency test and inter lab comparission?

 

[Hershal]

The procedures for PT/ILC come from ISO Guide 43 and ILAC G11.

ISO/IEC 17025 has four other methods listed, for the times when PT/ILC does not exist. NABL should have guidance on how to develop and implement one or more of those methods.

No Pts

our accreditation body NABL does not have the proficiency test and no any other clean room lab is accredited (ISO 17025) for interlab comparrision. For this case what can we do?

Hi All!

We had the same issue, but our accr. body told us that if no PT or round robin existed we should start our own. So we did. At the
same time our National Standards Lab has started a PTS, which in turn we will not participate. And imho our accr. body can not force us to do so

[Hershal]

Often the ILC will be acceptable if the PT was just beginning, and yours is established, however it is for the accrediting body to decide.

During the next assessment the PT issue will likely be revisited. If the PT is still available from your national body, the accrediting body can and may require it.

The best thing to do is to keep in touch with your accrediting body and discuss the PT issue with them.

Hope this helps.
