ISO 18400-201:2017 specifies methods for the pretreatment of samples that can be applied "in the field" directly after sampling. Pretreatment methods in this document are limited to: - sample division methods aimed at reducing the size/volume of the sample; - the production of composite samples; - the selection of a specific fraction of the sampled material. ISO 18400-201…

IEC 61291-5-2:2017 applies to optical amplifiers (OAs) and optically amplified, elementary sub-systems for terrestrial applications, using active fibres (optical fibre amplifiers (OFAs)) containing rare-earth dopants, which are commercially available. The black box approach is used in this document. The black box approach is adopted in order to give product specifications which are independent of…

IEC 62341-6-1:2017 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 62341-6-1:2017(E) specifies the standard measurement conditions and measuring methods for determining optical…

IEC 62341-6-1:2017(E) specifies the standard measurement conditions and measuring methods for determining optical and electro-optical parameters of organic light-emitting diode (OLED) display modules and, where specified, OLED display panels. These methods are limited to flat displays measured in a dark room. This second edition cancels and replaces the first edition published in 2009. This…

IEC TR 61869-100:2017(E) is applicable to inductive protective current transformers meeting the requirements of the IEC 61869-2 standard. It may help relay manufacturers, CT manufacturers and project engineers to understand how a CT responds to simplified or standardized short circuit signals. Therefore, it supplies advanced information to comprehend the definition of inductive current…

IEC 62946-02:2017(E) covers 8-way, unshielded free and fixed high density connectors for data transmission with frequencies up to 250 MHz and with extra low voltage current carrying capabilities up to 1 A, and is intended to specify the common dimensions, mechanical, electrical, signal integrity and environmental characteristics and tests for these connectors. The contents of the corrigendum of…

IEC 60794-1-2: 2017 applies to optical fibre cables for use with telecommunications equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors. The prime objective of this document is to provide the end user with an overview about the content of different parts of the IEC 60794-1 series numbered -2X. Table 1 shows the…

ISO 18134-2:2017 describes the method of determining the total moisture content of a test sample of solid biofuels by drying in an oven and is used when the highest precision is not needed, e.g. for routine production control on site. The method described in ISO 18134 (all parts) is applicable to all solid biofuels. The moisture content of solid biofuels (as received) is always reported based on…

IEC 61010-1:2010+A1:2016 specifies general safety requirements for the following types of electrical equipment and their accessories, wherever they are intended to be used. a) Electrical test and measurement equipment b) Electrical industrial process-control equipment c) Electrical laboratory equipment This third edition cancels and replaces the second edition published in 2001. It constitutes…
