Problemer med tilgang til standarder Det er for tiden problemer med tilgang til standarder i Global-abonnement, som API, ASTM, ASME, IEEE m.fl. Feilen påvirker flere tjenester internasjonalt, og det arbeides med å rette problemet.

Omfang

IEC TS 61000-1-6:2026, which is a Technical Specification, defines the test procedures used to establish uniform requirements for mechanical performance – galloping. It applies to optical fibre cables like ADSS, OPGW or OPPC that can be exposed to galloping phenomena.See IEC 60794-1-2 for general requirements and definitions and for a complete reference guide to test methods of all types.This first edition cancels and replaces the first edition of IEC TR 61000-1-6 published in 2012.This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previousedition:a) purpose of and responsibilities in measurement uncertainty evaluation by testing and calibration laboratories, technical committees dealing with EMC requirements have been introduced;b) classification of measurement uncertainty contributions (measurement uncertainty, measurement instrumentation uncertainty, intrinsic uncertainty of the measurand) has been revised;c) new clauses devoted to measurement uncertainty in emission test methods and measurement uncertainty in immunity test methods and in calibration have been added;d) methods of measurement uncertainty calculation have been enriched by introducing the GUM Supplement 1 (GUMS1) numerical approach based on Monte Carlo method;e) measurement uncertainty budget development has been revised to include the basic steps to follow in case of application of the GUM method or of the GUMS1 method;f) a clause specifically devoted to the measurement model function has been added to emphasize the importance of the measurement model and to provide guidance when the measurement model is unknown;g) the clause on probability density functions has been revised to include the Student-t probability density function;h) the clause on Type A and Type B evaluations of uncertainty has been revised to improve readability;i) the clause on the conversion from linear quantities to decibel and vice versa has been revised to improve readability and make some corrections;j) the clause on the applicability of measurement uncertainty has been modified to improve readability and to remove statements conflicting with conformity assessments standards;k) Annex A and Annex B have been revised by including results of GUMS1 application;l) new annexes have been introduced, namely Annex C (on metrological confirmation of measurement equipment), Annex D (on sampling statistics, moved from the main text to this annex to improve readability of the whole document), Annex E (on robust statistics for processing interlaboratory comparison data, with example), Annex F (including an example of application of MU for the assessment of the risk of an out of tolerance of measurement equipment) and Annex G (including an example of application of MU for the evaluation of in-tolerance probability as a function of tolerance to uncertainty ratio – TUR).
