IEC 61439-2:2020(E) defines the specific requirements for the power switchgear and controlgear assembly (abbreviated ‘PSC-assembly’ throughout this document see 3.1.101) as follows: <ul> <li>assemblies for which the rated voltage does not exceed 1 000 V AC or 1 500 V DC;</li> <li>assemblies designed for a nominal frequency of the incoming supply or supplies not exceeding…

IEC 61439-2:2020 defines the specific requirements for the power switchgear and controlgear assembly (abbreviated "PSC-assembly" throughout this document see 3.1.101) as follows: - assemblies for which the rated voltage does not exceed 1 000 V AC or 1 500 V DC; - assemblies designed for a nominal frequency of the incoming supply or supplies not exceeding 1 000 Hz; NOTE 1 Frequencies…

This document specifies requirements for the classification of solid wire electrodes, solid wires and rods for fusion welding of titanium and titanium alloys. The classification is based on their chemical composition. The compositions of solid wire electrodes for metal inert gas (MIG) welding are the same as solid wire electrodes, solid wires and rods for tungsten inert gas (TIG) arc welding,…

1 Scope This part of ISO/IEC 14543 enables a media connection, resource sharing and co-operation among computers, home appliances and consumer electronics using remote access (RA). Also, users and devices can share and control media resources. This document specifies: • an IGRS remote media access profile based on the IGRS RA core protocol and the IGRS RA platform protocol, and •…

1 Scope This document specifies a methodology for the evaluation of non-deterministic or deterministic random bit generators intended to be used for cryptographic applications. The provisions given in this document enable the vendor of an RBG to submit well-defined claims of security to an evaluation authority and shall enable an evaluator or a tester, for instance a validation authority, to…

IEC 62321-10:2020 specifies one normative technique for the determination of polycyclic aromatic hydrocarbons (PAHs) in polymers of electrotechnical products. These PAHs can especially be found in the plastic and rubber parts of a wide range of consumer articles. They are present as impurities in some of the raw materials used in the production of such articles, in particular in extender oils and…

This document specifies requirements and test methods for central compressed air source equipment supplying dental air for dental units and various dental air consuming devices in the dental office. It also specifies quality requirements and test methods for the dental air produced by the central compressed air source equipment, such as requirements for the purity level of dental air. It also…

IEC 62257-9-8:2020 provides baseline requirements for quality, durability and truth in advertising to protect consumers of off-grid renewable energy products. Evaluation of these requirements is based on tests described in IEC TS 62257-9-5. This document can be used alone or in conjunction with other international standards that address the safety and durability of components of off-grid…
