This document is intended to be applied to safety-related systems that include one or more electrical and/or electronic (E/E) systems and that are installed in series production road vehicles, excluding mopeds. This document does not address unique E/E systems in special vehicles such as E/E systems designed for drivers with disabilities. NOTE Other dedicated application-specific safety…

IEC/IEEE 60255-118-1:2018 is used for synchronized phasor measurement systems in power systems. It defines a synchronized phasor (synchrophasor), frequency, and rate of change of frequency measurements. It describes time tag and synchronization requirements for measurement of all three of these quantities. It specifies methods for evaluating these measurements and requirements for compliance with…

IEC 60512-23-3:2018 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 60512-23-3:2018. defines a standard test method for measuring the shielding effectiveness SE of a shielded…

EC 61850-8-2:2018 specifies a method of exchanging data through any kinds of network, including public networks. Among the various kinds of services specified in IEC 61850-7-2, only the client/server and time synchronization services are considered so far. NOTE Client/server services of GOOSE and SMV models are mapped as well. For the client/server services, the principle is to map the objects…

IEC 60512-23-3:2018. defines a standard test method for measuring the shielding effectiveness SE of a shielded connector, or of a connector not provided with integral shield once fitted with a shielding accessory and terminated with a screened cable. The complete assembly has a continuous 360° shielding capability throughout its length. This test method can be applied to shielded connectors and…

IEC 60793-2-50:2018 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 60793-2-50: 2018 is applicable to optical fibre categories B-652, B-653, B-654, B-655, B 656 and B-657. A map…

IEC 60793-2-50: 2018 is applicable to optical fibre categories B-652, B-653, B-654, B-655, B 656 and B-657. A map illustrating the connection of IEC designations to ITU-T designations is shown in Table 1. These fibres are used or can be incorporated in information transmission equipment and optical fibre cables. Three types of requirements apply to these fibres: • general requirements, as…

This document defines the specifications and the type tests for quick-action couplings with shut-off valves. It applies to quick-action couplings used between the regulator and the torch in equipment for gas welding, cutting and allied processes. This document applies to cases where these couplings are used with hoses in accordance with ISO 3821 or threaded unions in accordance with ISO/TR 28821.

IEC 62464-1:2018 specifies measurement procedures for the determination of many essential image quality parameters for MR EQUIPMENT. Measurement procedures as addressed in this document are suitable for – quality assessment in the ACCEPTANCE TEST, and – quality assurance in the CONSTANCY TEST. Required levels of performance for ACCEPTANCE TESTS are not provided for all tests. This document…

This document specifies tests, procedures and a method of presenting the results concerning the parameters that define the main characteristics to be included in the supplier's literature of lubricators conforming to ISO 6301‑1. This document can be applied: — to facilitate the comparison of lubricators by standardizing test methods and presentation of test data; — to…
