Paper, board and pulps. General requirements for the competence of laboratories authorized for the issue of optical reference transfer standards of level 3
1 Scope
This document provides both general requirements and specific requirements (Annex A) for laboratories seeking to become
“ Authorized Laboratories (ALs)” and to maintain their Authorized Laboratory status
for the issue of optical reference transfer standards of level 3. This document
follows the requirements and adopts the format of
ISO/IEC 17025,
with the aims of:
a) establishing and maintaining international optical reference transfer
standards of level 2 ( IR2 ) traceable to an international optical reference
primary standard of level 1 ( IR1 ) maintained by a standardizing
laboratory;
b) distributing traceability required to achieve inter-laboratory agreement in
the results of test methods specified in International Standards for optical
properties of paper, board or pulp;
c) participating in the design and development of new methods and international
harmonization of procedures.
When a laboratory does not undertake one or more of the activities covered by this
document, such as sampling and the design/development of new methods, the
requirements of those clauses do n...
