IEC 61158-5-24:2023 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 24 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…

IEC 61158-3-28:2023 describes basic packet communication services and models in an automation control industrial field environment. The Type 28 data-link layer provides time-critical and non-time-critical communication services. Time-critical refers to the requirement to complete specified functions between devices in a defined time window in an industrial field environment. Failure to complete…

IEC 61784-1-22:2023 defines Communication Profile Family 22 (CPF 22). CPF 22 specifies a protocol specific communication profile (CP) based on the IEC 61158 series (Type 28) 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 published by…

IEC 61158-5-27:2023 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 27 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…

IEC 61784-2-19:2023 defines extensions of Communication Profile Family 19 (CPF 19) for Real-Time Ethernet (RTE). CPF 19 specifies a Real-Time Ethernet (RTE) communication profile (CP) and related network components based on the IEC 61158 series (Type 27), ISO/IEC/IEEE 8802-3 and other standards.

IEC 61196-1-123:2023 defines the test method to determine the attenuation constant of radiating coaxial communication cables that are intended for use in wireless communication systems such as tunnels, railways, highways, subways, elevators and other confined areas in which conventional antenna transmission is not satisfactory or even impossible.

This document defines an index to the complete set of TPEG Generation 2 toolkit components and applications. New applications are enumerated with an application identification (AID) as they are added to the TPEG applications family. NOTE 1 This document will be updated when new applications occur in order to indicate the latest status and the inter-working of the various TPEG specifications. This…

This document specifies the characteristics of the system of physical photometry established by the CIE and accepted as the basis for the measurement of light. It defines the photometric quantities, units and standards that make up the CIE system of physical photometry and that have been officially accepted by the Comité International des Poids et Mesures (CIPM). This comprises: —    the…

1 Scope 1.1 Organization and content This standard applies to the design, manufacture, maintenance, qualification, inspection and marking of tank cars and the selection and use of large means of containment or transport units used in the handling, offering for transport or transporting of dangerous goods by rail of classes 2, 3, 4, 5, 8, 9 and division 6.1. This standard does not apply to…

1 Scope 1.1 General This Standard applies to frames and covers for maintenance holes and catchbasins. 1.2 Terminology In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an…
