Anotácia textu normy IEC 61280-2-8-ed.2.0-RLV :
IEC 61280-2-8:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61280-2-8:2021 specifies two main methods for the determination of low BER values by making accelerated measurements. These include the variable decision threshold method (Clause 5) and the variable optical threshold method (Clause 6). In addition, a third method, the sinusoidal interference method, is described in Annex B. This second edition cancels and replaces the first edition published in 2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - correction of errors in Formula (8) in 5.5.2 and in a related formula in 5.5.3; - correction of errors in the references to clauses, subclauses, figures, procedures, and in the Bibliography; - alignment of the terms and definitions in 3.1 with those in IEC 61281-1.
