IEC 60512-99-002:2019. est utilisée pour soumettre à essai des connecteurs relevant du domaine d’application du SC 48B, qui sont utilisés dans les câblages de communication à paires torsadées permettant une alimentation à distance, tels que les câblages symétriques de la classe D (ou d'une classe correspondant à une fréquence supérieure) de l’ISO/IEC 11801, à l’appui de la norme IEEE 802.3bt™ (alimentation électrique par câble Ethernet améliorée/PoE Plus, Power over Ethernet Plus).
L’objet du présent document est de détailler un programme d’essai permettant de déterminer l’aptitude des paires de connecteurs à supporter une séquence d'essais de 100 accouplements et désaccouplements au total. Le courant électrique traverse les connecteurs au cours du désaccouplement uniquement, conformément à l’IEC 60512-9-3.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 10322-2 was prepared by Technical Committee
lSO/TC 172, Optics and optical instruments, Subcommittee SC 8,
Ophthalmic optics.
This second edition cancels and replaces the first edition
(IS0 10322-2:1991), which has been technically revised.
IS0 10322 consists of the following parts, under the general title
Ophthalmic optics - Semi-finished spectacle lens blanks:
- Part 7: Specifications for single-vision and multifocal lens blanks
- Part 2: Specifications for progressive power lens blanks
Annexes A, B and C of this part of IS0 10322 are for information only.
