IEC 61156-11:2019 describes cables intended to be used for transmission of 1 Gbps over a single twisted pair for office, home and industrial application. An example of existing application is 1000BASE-T1, see ISO/IEC TR 11801-9906. The transmission characteristics of these cables are specified up to a frequency of 600 MHz and at a temperature of 20 °C. The cable type recognised is intended to be…

1.1 Purpose This International Standard defines a method for automating the counting of Function Points that is generally consistent with the Function Point Counting Practices Manual, Release 4.3.1 (IFPUG CPM) produced by the International Function Point Users Group (IFPUG). Guidelines in this International Standard may differ from those in the IFPUG CPM at points where subjective judgments…

This document specifies requirements for the maximum amount and, in some cases, the maximum concentration of certain substances and mixtures used in experimental sets for chemistry and related activities. These substances and mixtures are: — those classified as dangerous by the Globally Harmonized System of Classification and Labelling of Chemicals (GHS)[1]; — substances and…

This document specifies requirements and test methods for the substances and materials used in chemical toys (sets) other than experimental sets. These substances and mixtures are: — those classified as dangerous by the Globally Harmonized System of Classification and Labelling of Chemicals (GHS)[1]; — substances and mixtures which in excessive amounts could harm the health of…

This document specifies a test method for evaluating nodularity in spheroidal graphite cast irons by comparative visual analysis and image analysis techniques. This document provides figures for different levels of nodularity and graphite particle count of spheroidal graphite cast irons for visual analysis.

This document defines a syntax (and an accompanying decompression process) that is capable to represent continuous-tone grey-scale, or continuous-tone colour digital images without visual loss at moderate compression rates. Typical compression rates are between 2:1 and 6:1 but can also be higher depending on the nature of the image. In particular, the syntax and the decoding process specified in…

This document specifies the following mechanisms for homomorphic encryption. — Exponential ElGamal encryption; — Paillier encryption. For each mechanism, this document specifies the process for: — generating parameters and the keys of the involved entities; — encrypting data; — decrypting encrypted data; and — homomorphically operating on…

This document specifies an aggregation process that provides aggregated environmental performance evaluation data in accordance with a given environmental performance evaluation specification conforming to ISO 20140-2, by using a set of environmental performance evaluation data conforming to ISO 20140-5. This document does not specify any aggregation processes specific to particular…

This document describes the data link layer (DLL) and physical layer (PHY) for the two CAN-based network interfaces specified in the 11992-series. The DLL sub-clauses are composed of: — DLL protocol entity requirements; — DLL device interface requirements; and — DLL network system requirements. Normally, the physical signalling sub-layer is implemented in the CAN…
