Optical fibres - Part 2-10: Product specifications - Sectional specification for category A1 multimo...
IEC 60793-2-10:2017 is applicable to optical fibre sub-categories A1a, A1b, and A1d. These fibres are used or can be incorporated in information transmission equipment and optical fibre cables. Sub-category A1a applies to 50/125 mm graded index fibre. Four bandwidth grades are defined as models A1a.1, A1a.2, A1a.3 and A1a.4. Each of these bandwidth grades is defined for two levels of macrobend…
Learning services outside formal education — Service requirements
ISO 29993:2017 specifies requirements for learning services outside formal education, including all types of life-long learning (e.g. vocational training and in-company training, either outsourced or in-house). These include any learning services provided by a learning service provider (LSP) that are addressed to learners themselves, as well as to sponsors who are acquiring the services on behalf…
Mechanical vibration — Measurement and evaluation of human exposure to hand transmitted vibration — ...
ISO/TR 18570:2017 provides guidance on a supplementary method to that defined in ISO 5349‑1 for measuring and reporting hand-transmitted vibration exposures. The method defined in this document provides an improved assessment methodology for evaluating vascular hand-arm vibration risks (vibration white finger). This document does not apply for other health effects (e.g. sensorineural and…
Timber structures — Determination of characteristic values — Part 6: Large components and assemblies
ISO 12122-6:2017 specifies methods of determination of characteristic values for a defined population of large components and assemblies, calculated from test values.
It establishes two methods for the determination of characteristic values:
a) direct calculation from test values;
b) calculation from a resistance model, which is firstly calibrated from test results, including calculation of…
Rubber, vulcanized — Determination of tension fatigue
ISO 6943:2017 specifies a method for the determination of the resistance of vulcanized rubbers to fatigue under repeated tensile deformations, the test piece size and frequency of cycling being such that there is little or no temperature rise. Under these conditions, failure results from the growth of a crack that ultimately severs the test piece.
The method is restricted to repeated deformations…
Information technology — MPEG systems technologies — Part 4: Codec configuration representation
ISO/IEC 23001-4:2017 defines the methods and general principles capable of describing codec configurations in the reconfigurable video coding (RVC) framework. It primarily addresses reconfigurable video aspects and will only focus on the description of representation for video codec configurations within the RVC framework.
Within the scope of the RVC framework, two languages, namely FNL and RVC-…
