This document specifies the abstract class of a media thing (MThing), which is a basic component to construct the Internet of media things. The MThing class contains the basic APIs to: — discover other MThing(s) in the network; — connect/disconnect MThing(s); — support transactions (e.g. payments) using media tokens between MThings.

IEC PAS 63422:2022(E) Book 20 defines a smart interface between an indoor LED luminaire and a sensing/communication module. The module connects to the LED driver and control system, and typically can provide sensory inputs or enable communication between network components. Modules can be installed and replaced in the field. Book 1 defines the common concepts that underlie the Zhaga interface…

IEC TS 63106-2:2022 provides recommendations for Low Voltage (LV) DC power simulators used for testing photovoltaic (PV) power conversion equipment (PCE) to utility interconnection or PV performance standards. This document primarily addresses DC power simulators used for testing of grid-interactive PCE, also referred to as grid-connected power converters (GCPCs). It also addresses some uses of…

This document specifies requirements for ten classes, four grades and seven types of wire- or textile-reinforced hydraulic hoses and hose assemblies of nominal sizes ranging from 5 to 102. Each class has a single maximum working pressure for all sizes. They are suitable for use with: —    oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743‑4 at temperatures ranging from −40 °C…

1 Scope 1.1 This standard applies to bare and covered ferrules intended for field wiring and factory wiring for use in accordance with the National Electrical Code, ANSI/NFPA-70, and Canadian Electrical Code, Part I, CSA C22.1. 1.2 Ferrules covered by this standard are intended to facilitate the connection of stranded wire onto devices, such as terminal blocks and mechanical wire connectors…

1 Scope 1.1 These requirements cover polyvinyl chloride (PVC) pressure pipe, machined couplings, fabricated fittings and gaskets and oriented polyvinyl chloride (PVCO) pressure pipe and gaskets for use in underground fire protection systems and connections to such systems. 1.2 These requirements do not cover fittings that consist of mechanical joint retainer devices even when intended for…

This document specifies basic safety and performance requirements for medical suction equipment powered from a vacuum or positive pressure gas source generating venturi suction. It applies to suction equipment connected to medical gas pipeline systems or cylinders and venturi attachments and can be standalone or part of an integrated system.

This document provides procedures for assessment of casing connections for those field applications in which the operating temperatures cyclically vary between minimum values appreciably below 180 °C and maximum values that range from 180 °C to 350 °C or above, and in which the primary axial loading on the casing-connection system is strain-based and driven by constrained thermal expansion and…

1.1 Scope and object This part of IEC 60947 applies to inductive and capacitive proximity switches that sense the presence of metallic and/or non-metallic objects, ultrasonic proximity switches that sense the presence of sound reflecting objects, photoelectric proximity switches that sense the presence of objects and non-mechanical magnetic proximity switches that sense the presence of…

1.1 Domaine d'application e t objet La présente partie de la CEI 60947 s'applique aux détecteurs de proximité inductifs et capacitifs qui détectent la présence d'objets métalliques et/ou non métalliques, aux détecteurs de proximité ultrasoniques qui détectent la présence d'objets réfléchissants les ultrasons, aux détecteurs de proximité photoélectriques qui détectent la…
