This document defines a measurement method for the evaluation of distortions in the macroscopic uniformity of printed areas that are oriented in the horizontal and vertical direction, such as streaks and bands. It provides requirements for the layout of the test form, the use of a colour measurement device taking measurements in a 2D sampling grid, and the formula to compute the Macro-Uniformity-…

IEC 61591:2023 applies to cooking fume extractors incorporating a fan for the recirculation or extraction mode situated in a household kitchen. It can also be used for cooking fume extractors where the fan is mounted separately from the appliance, but controlled by the appliance when the fan is defined in the technical documentation (e.g. name plate data) and instructions for installation. This…

IEC 61591:2023 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 61591:2023 edition 3.0 and the previous IEC 61591:2019 edition 2.0. Furthermore, comments from IEC SC 59K experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content…

This document specifies the test conditions for the determination of the tensile properties of isotropic and orthotropic fibre-reinforced plastic composites, based upon the general principles given in ISO 527-1. NOTE 1   Unidirectional reinforced materials are covered by ISO 527-5. The methods are used to investigate the tensile behaviour of the test specimens and for determining the tensile…

This document specifies an additional test for verifying the stability of a laden truck fitted with a powered load-handling device, such as a sideshift, which can displace the centre of gravity laterally to a substantial, predetermined extent from the longitudinal centre plane of the truck or from the centred position. Such devices are used in this mode for depositing and retrieving a load. A…

This document specifies an additional test for verifying the stability of a laden truck whose utilization creates the special operating condition whereby the load centre of gravity is substantially offset from the truck's longitudinal centre plane or from the centred position by design. A load is considered to be substantially offset if displaced by more than: —    100 mm, for a truck with a…

IEC 61784-1-0:2023 series defines several Communication Profile Families (CPF). Each CPF specifies a set of protocol specific communication profiles (CPs) based primarily on the IEC 61158 series, to be used in the design of devices involved in communications in factory manufacturing and process control. This part of IEC 61784-1 defines a common terminology for all CPFs and conventions to be used…

IEC 61784-1-9:2023 defines Communication Profile Family 9 (CPF 9). CPF 9 specifies a set of protocol specific communication profiles (CPs) based on the IEC 61158 series (Type 20) and other standards, to be used in the design of devices involved in communications in factory manufacturing and process control. NOTE All CPs are based on standards or draft standards or International Standards…

IEC 61784-1-16:2023 defines Communication Profile Family 16 (CPF 16). CPF 16 specifies a set of protocol specific communication profiles (CPs) based on the IEC 61158 series (Type 16 and Type 19) and other standards, to be used in the design of devices involved in communications in factory manufacturing and process control. NOTE 1 All CPs are based on standards or draft standards or International…

IEC 61158-6-23:2023 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 23 fieldbus. The term "time-critical" is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level…
