PROOF / ACCREDITATION
Accreditation
The laboratory holds two accreditation certificates from the Saudi Accreditation Center, both to ISO/IEC 17025:2017 — one for calibration, one for testing. They are reproduced below from the documents themselves, together with the scope annex that defines exactly what they cover, and what they do not.

ANNEX
The scope, line by line
Accreditation applies line by line, never to a laboratory as a whole. The ledger reproduces the scope annex of certificate N-C-00592 in full — each parameter with its accredited range and CMC, grouped by field exactly as the annex prints them — and the accompanying figure draws those ranges to scale.
Mass measurements
04 LINES| Parameter | Range | CMC ± uncertainty |
|---|---|---|
| Mass measurements, F1 and below class weights | 1 g, 2 g, 5 g, 10 g, 20 g, 50 g, 100 g, 200 g | 0.000010 g to 0.00010 g |

BOUNDARY
What is not covered
A scope is defined as much by what it excludes as by what it contains. The statements below carry the same weight as the certificates above: work outside the scope is available, and it is said to be outside the scope before it is commissioned.
Not accredited
Dimensional calibration
Dimensional calibration is offered as non-accredited in-house work. It has no line in the scope annex, and no certificate from this discipline carries or implies an accreditation mark.
Not accredited
Electrical calibration
Electrical calibration is offered as non-accredited in-house work. It has no line in the scope annex, and no certificate from this discipline carries or implies an accreditation mark.
Where testing stops
Testing stops at food and agricultural microbiology
Certificate N-T-00607 covers food and agricultural microbiological testing, and nothing else. No other testing field is accredited, and no page on this site implies otherwise.
VERIFICATION
How to verify these credentials
This page is the laboratory’s account of its own accreditation. The authoritative record is the public register of the issuer, and checking it takes three steps.

Take the certificate number
Calibration is held under N-C-00592 and testing under N-T-00607. A certificate number is a claim until it has been checked against the body that issued it.
Consult the SAAC public register
The Saudi Accreditation Center maintains the public register of accredited laboratories in Saudi Arabia. An entry there under these numbers is the confirmation that matters — this website is not the source of record.
Read the scope, not the badge
Confirm that the line covering the instrument or sample in question appears in the annex above. Accreditation applies to those lines, and to nothing beyond them.
CYCLE
Accreditation runs on a cycle
An accreditation certificate is not a permanent award. It is issued for a period, kept under surveillance within that period, and renewed before it lapses — which is why the validity dates above are printed as prominently as the numbers.
