JCGM-developed 'Guidance' documents

A1 Status
A.1.1 Guidance documents prepared as a result of the Joint Committee’s work have no mandatory status by themselves.
A.1.2

Guidance documents aim primarily at harmonizing worldwide current metrological practices and disseminating scientific and technological knowledge.  They constitute recommendations that member organizations are strongly encouraged to implement.

A.2 Document production and publication
A.2.1 JCGM Guidance documents are prepared in LaTeX or Word, from which PDF versions, including hyperlinks, can be readily produced. The final version of a document, approved by the member organizations, constitutes an ‘official version’, owned by the JCGM.
A.2.2 JCGM official documents are distributed in PDF format to member organizations for publication according to paragraph 7.1.6 of the Charter. Member organizations may publish JCGM documents in PDF format or as paper copies against payment of for free taking into account the provisions of paragraph A.2.4.
A.2.3 Maintaining the LaTeX or Word files and the production of PDF versions from these files is the responsibility of the JCGM Working Group that drafted the document. This applies both to ‘official versions’ of JCGM documents and member organization specific publications of JCGM documents in case the LaTeX or Word files are used to prepare a member organization specific publication.
A.2.4

The publication of a JCGM document by a member organization shall be an exact reproduction of the ‘official version’ with the following additions:

A.2.4.1 On the cover page the logo, acronym and title of the member organization shall be added. Alternatively, a separate cover page may be added before the JCGM cover page with, as a minimum, the member organization’s logo, acronym and title, the title of the publication and the JCGM reference number.

A.2.4.2 Optionally, the following may be added:
- a member organization specific copyright page,
- a member organization specific foreword,
- a table of correspondence between the bibliographic references in the official version and corresponding publications of the member organization,
- additional information specific to the member organization.

A.3 Copyright owner
A.3.1 Copyright of any JCGM document is shared jointly by the JCGM's member organizations.
A.3.2 JCGM documents published in accordance with paragraph A.2.4 become new publications for which the member organization concerned is the copyright owner. The member organization concerned shall not be requested to pay any royalties to the JCGM or to its member organizations.
A.4 Implementation of Guidance documents by member organizations
A.4.1 Dissemination of Guidance documents is the responsibility of the member organizations, each within its respective sphere of competence.
A.4.2 When a member organization decides to implement a Guidance document prepared by the Joint Committee (see Joint Committee Charter, subclause 7.1.6), it has the right to do so in accordance with its own internal rules and procedures.
A.5 Financial arrangements
A.5.1 Any financial arrangements regarding the publication and distribution of Guidance documents in whatever formats shall be decided by common agreement between the member organizations.
A.5.2 The provision in A.5.1 does not apply to documents processed in accordance to A.3.2.
