Optical fibres - Part 1-31: Measurement methods and test procedures - Tensile strength
IEC 60793-1-31:2019 provides values of the tensile strength under dynamic loading of optical fibre samples. The method tests individual lengths of uncabled and unbundled glass optical fibre. Sections of fibre are broken with controlled increasing stress or strain that is uniform over the entire fibre length and cross section. The stress or strain is increased at a nominally constant rate until…
Fibres optiques - Partie 1-31: Méthodes de mesure et procédures d'essai - Résistance à la tract...
IEC 60793-1-31:2019 donne les valeurs de résistance à la traction des échantillons de fibre optique, soumis à une charge dynamique. Cette méthode soumet à essai des longueurs individuelles de fibre optique en verre, non câblées et non groupées en faisceau. Des sections de fibre sont rompues en les soumettant à une contrainte ou une déformation croissante et contrôlée, uniforme sur toute la…
Dynamic modules - Part 1: Performance standards - General conditions
IEC 62343-1:2019 provides general conditions for the standard performance of optical dynamic modules. All performance standards of dynamic modules are based on the general conditions defined in this document. Additional conditions are included in individual performance standards. This second edition cancels and replaces the first edition, published in 2016, and constitutes a technical revision.…
Modules dynamiques - Partie 1: Normes de performance - Conditions générales
IEC 62343-1: 2019 fournit les conditions générales en vue de la performance normalisée des modules dynamiques optiques. L'ensemble des normes de performance des modules dynamiques sont fondées sur les conditions générales définies dans le présent document. Des conditions complémentaires sont incluses dans des normes de performance individuelles. Cette édition inclut les modifications…
Systems and software engineering — Life cycle management — Part 8: Technical reviews and audits on d...
This document establishes the requirements for technical reviews and audits to be performed throughout the acquisition life cycle for the US Department of Defense (DoD) and other defense agencies. This document provides the definition, description, and intent, as well as the entry, exit and success criteria, for each technical review and audit. It is to be used to establish agreement between…
Furniture — Storage units — Test methods for the determination of stability
This document specifies test methods for determining the stability of free-standing storage units that are fully assembled and ready for use.
The test results are only valid for the unit/component tested. These results can be used to represent the performance of production models provided that the tested model is representative of the production model.
This document specifies test methods only.…
