IEC 62541-6:2020 specifies the OPC Unified Architecture (OPC UA) mapping between the security model described in IEC TR 62541-2, the abstract service definitions specified in IEC 62541-4, the data structures defined in IEC 62541-5 and the physical network protocols that can be used to implement the OPC UA specification. This third edition cancels and replaces the second edition published in 2015…
IEC 63252:2020 defines methods for the measurement of energy consumption of vending machines, whether or not fitted with refrigerating appliances.
The standard applies (but is not limited) to the following categories of machines:
- Refrigerated closed-fronted can and bottle machines where the products are held in stacks
- Refrigerated glass-fronted can and bottle, confectionery and snack…
IEC 62541-4:2020 defines the OPC Unified Architecture (OPC UA) Services. The Services defined are the collection of abstract Remote Procedure Calls (RPC) that are implemented by OPC UA Servers and called by OPC UA Clients. All interactions between OPC UA Clients and Servers occur via these Services. The defined Services are considered abstract because no particular RPC mechanism for…
Road vehicles — Extended Vehicle (ExVe) time critical applications — General requirements, definitio...
This document defines the classification methodology of time-constrained situations and their requirements, that are to be addressed by the "ExVe time critical interfaces" described in ISO 20077‑1. Time-constrained situations include safety-critical situations.
It is important for the design of the vehicle to have priority management of "ExVe time critical interface" resources…
OPC Unified Architecture - Part 5: Information Model
IEC 62541-5:2020 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 62541-5:2020 defines the Information Model of the OPC Unified Architecture. The Information Model describes…
OPC Unified Architecture - Part 5: Information Model
IEC 62541-5:2020 defines the Information Model of the OPC Unified Architecture. The Information Model describes standardized Nodes of a Server’s AddressSpace. These Nodes are standardized types as well as standardized instances used for diagnostics or as entry points to server-specific Nodes. Thus, the Information Model defines the AddressSpace of an empty OPC UA Server. However, it is not…
This document defines terms related to bamboo, intermediate bamboo and bamboo products.
This document is applicable to bamboo, intermediate bamboo and bamboo products in production and trade.
Power transformers - Part 24: Specification of voltage regulating distribution transformers (VRDT)
IEC 60076-24:2020 applies to medium power transformers from 25 kVA up to 3 150 kVA with highest voltage for equipment up to 36 kV, or in low voltage (LV) networks with highest voltage for equipment of up to 1,1 kV equipped with voltage regulating devices. Voltage regulating distribution transformers are transformers equipped with components to control primary or secondary voltage for on-load…
Clevis and tongue couplings of string insulator units - Dimensions
IEC 60471:2020 applies to string insulator units of the cap and pin type and also of the long rod type as well as the fittings used with such insulators. The object of this document is to define the dimensions of a series of clevis and tongue couplings to permit the assembly of insulators or fittings supplied by different manufacturers.
This third edition cancels and replaces the second edition…
Machine tools — Environmental evaluation of machine tools — Part 3: Principles for testing metal-cut...
This document supports the energy-saving design methodology according to ISO 14955‑1 and the methods for measuring energy supplied to machine tools and machine tool components defined in ISO 14955‑2. This document addresses the environmental evaluation of machine tools during the use stage based on reference scenarios. It contains an example for metal cutting machine tools.
This document defines…
