Dear Mohamed:

They are almost identical, with two exceptions.

First the 2005 version requirement to have the lab ensure that the environment remains a safe workspace by making sure it is neat are gone (17025:2005 5.3.5 is gone).

Second the 2017 version specifies that offsite testing by the lab is done under conditions that continue to provide for technically valid results.

Demonstrating conformance is identical if the lab does not do offsite testing. Demonstrating conformance requires demonstration of environmental controls appropriate to the needs of the work if done offsite, under the new version.

That's it.

This OK?

YES Ned the standard write that all technician were checking during assessment

Yes...i agree with Ned...almost identical

I wish if there's anyone can help me about if there's a validation for microbiology test or not... And if there's any difference between micro validation and wet chemistry....????

Validation of Microbiological Testing Methods Accuracy: The exactitude of an analytical methodexplains how close the mean test results obtained are to
the real value of the analyte . The replicateanalysis of samples containing known amounts of theanalyte determines the accuracy
Precision: explains thecloseness of individual measures of an analyte when theprocedure is done again and again on various aliquots witha homogeneous volume of biological matrixRepeatability: calculated when authenticating a method being a measure ofagreement of replicate tests carried out on the same material in the same a
laboratory by the analysts Selectivity/Specificity: This is the capability of ananalytical proof to verify and quantify the analytes among
other components in the sampleSensitivity: Sensitivity of the test method should bemade and can be explained as the limit of accurate
Stability: Procedures have to measure the stability
LOD LOQ minimum amount of organisms identified-counted
