Awarded to

NATIONAL METRLOGY INSTITUTE OF PAKISTAN

PLOT NO. 16, SECTOR H-9/1, ISLAMABAD, PAKISTAN.

The scope of accreditation is in accordance with the standard specifications

outlined in the following page(s) of this document. The accredited scope shall be
visible and legible in areas such as customer service, sample-receiving section etc
and shall not mislead its users.

The accreditation was first time granted on 12-02-2004 by Pakistan National

Accreditation Council.

The laboratory complies with the requirements of ISO/IEC 17025:2017.

The accreditation requires regular surveillance, and is valid until 11-02-2025.

The decision of accreditation made by Pakistan National Accreditation Council

implies that the organization has been found to fulfill the requirements for
accreditation within the scope.

The organization however, itself is responsible for the results of performed

measurements/tests.

* Expanded Uncertainty:
 Expanded Uncertainty is the measurement uncertainty at a coverage probability of 95 %,
which usually requires the use of a coverage factor of k = 2. This measurement
uncertainty is a value for which the laboratory has been accredited using the procedure
that was the subject of assessment. In certificates issued under its accreditation scope an
accredited laboratory is not permitted to quote an uncertainty that is smaller than the
published uncertainty for respective ranges as given above.
