3.1

Standardizing Laboratory

laboratory of a national metrology institute (NMI) or designated institute (DI) that complies with the requirements of the International Committee of Weights and Measures (CIPM) Mutual Recognition Arrangement (MRA) for international recognition of its capabilities to maintain in safe custody, or otherwise realize the international reference standard of level 1 (notation IR1) (3.4), to transfer the traceability of IR1 (3.4) to level 2 (notation IR2) (3.5)

Note 1 to entry: These internationally recognized calibration and measurement capabilities (CMCs) of NMIs and DIs that are signatories to the CIPM MRA are published in the key comparison database, maintained by the Bureau International des Poids et Mesures (BIPM).

3.2

Authorized Laboratory

AL

laboratory complying with the general requirements of this document and other specific requirements (Annex A) that transfers the traceability of international reference standards of level 2 (notation IR2) (3.5) to level 3 (notation IR3) (3.6)

3.3

Authorized Laboratory requirements

set of specified requirements to be fulfilled in order to establish or maintain authorized status

3.4

international reference standard level 1

IR1

primary optical reference standard, the perfect reflecting diffuser, the ideal diffuser exhibiting isotropic diffuse reflection with a reflectance equal to 1, used for calibration of optical transfer standards

Note 1 to entry: Reflectance is defined as the ratio of the reflected to the incident radiation.

3.5

international reference standard level 2

IR2

secondary optical reference transfer standard for the certification of level 3 (IR3) (3.6) standards or for the calibration of instruments, consisting of a material certified against an international reference standard of level 1 (3.4) by a Standardizing Laboratory (3.1) , as specified in the relevant International Standard

Note 1 to entry: This document refers to two types of IR2: a non-fluorescent IR2, whose spectral reflectance factors have been determined by a Standardizing Laboratory in relation to the IR1; and a fluorescent IR2, whose total spectral radiance factors corresponding to a specified CIE illuminant have been determined by a Standardizing Laboratory. A non-fluorescent IR2 is used to calibrate the photometric scale of an Authorized Laboratory’s reference instrument, and a fluorescent IR2 standard is used to adjust the UV level of an Authorized Laboratory’s reference instrument.

3.6

international reference standard level 3

IR3

tertiary optical reference transfer standard consisting of a material certified against an international reference standard of level 2 (3.5) by an Authorized Laboratory (3.2) , as specified in the relevant International Standard, and used by a testing laboratory for the calibration of instruments

Note 1 to entry: This document refers to two types of IR3: a non-fluorescent IR3, whose spectral reflectance factors have been determined by an Authorized Laboratory in relation to the non-fluorescent IR2; and a fluorescent IR3, whose calibration values have been determined by an Authorized Laboratory in relation to the fluorescent IR2. A non-fluorescent IR3 is used to calibrate the photometric scale of a testing laboratory’s instrument. A testing laboratory uses a fluorescent IR3 to adjust the UV level of the testing laboratory’s instrument.

3.7

peer review

name given to judgement of scientific merit by other scientists working in, or close to, the field in question

Note 1 to entry: For a laboratory to be formally authorized for the dissemination of international reference standards of level 3 (IR3) (3.6), the assessment of its compliance with the requirements of this document and other relevant ISO TC6 standards is carried out by peer review by one or more technical managers of the existing Authorized Laboratories or their designates.

3.8

testing laboratory

laboratory that calibrates testing instrumentation with an IR3
