Scope This National Standard of Canada defines equipment requirements, performance criteria, and operating and testing procedures for the implementation of a vapour control system (VCS) in gasoline distribution networks including terminals, bulk plants, service stations and cargo tanks, commonly known as Stage I controls (see Figure 1 for a schematic representation). This standard does not…

IEC 60115-4-10:2023(E) is applicable to the drafting of detail specifications for fixed power resistors with leads, classified to level G, which is defined in IEC 60115‑1:2020, 3.4 for general electronic equipment. It is a supplementary document to the sectional specification and contains requirements for style, layout and minimum contents of detail specifications.

IEC 60938-2-1:2023 is applicable to the drafting of detail specifications for fixed inductors for which safety tests are required for use in electronic equipment. A blank detail specification is a supplementary document to the sectional specification and contains requirements for style, layout and minimum content of detail specifications. Detail specifications not complying with these…

IEC 60966-3-1:2023 is a blank detail specification that relates to semi-flexible coaxial cable assemblies operating in the transverse electromagnetic mode (TEM). The creation of a uniform layout and style of detail specifications is determined by the use of a blank detail specification pro forma. The detail specification can be prepared by the insertion of data into the pro forma by a national…

IEC 61196-8-1:2023 applies to coaxial communication cables described in IEC 61196-8. It specifies the requirements of semi-flexible coaxial communication cables with fluoropolymer dielectric and tin soaked copper wire braid outer conductor. These cables are intended for use in mobile communication base station antenna systems, terrestrial microwave communication, radar systems and wireless…

IEC 61196-9-1:2023 applies to coaxial communication cables described in IEC 61196-9. It specifies the requirements of flexible coaxial communication cables with solid or semi-air-spaced dielectric and wrap or/and braid outer conductor. These cables are widely used in mobile communication systems, microwave test equipment, consumer electronics and other fields. This document determines the layout…

IEC 60383-1:2023 applies to insulators of ceramic material or glass for use on AC overhead power lines and overhead traction lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It also applies to insulators for use on DC overhead electric traction lines. This document applies to string insulator units, rigid overhead line insulators and to insulators of…

IEC 60287-1-3:2023 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 60287-1-3:2023 edition 2.0 and the previous IEC 60287-1-3:2002 edition 1.0. Furthermore, comments from IEC TC 20 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of…

IEC 60287-1-3:2023 provides a method for calculating the phase currents and circulating current losses in single-core cables arranged in parallel. The method described in this document can be used for any number of cables per phase in parallel in any physical layout. The phase currents can be calculated for any arrangement of sheath bonding. For the calculation of sheath losses, it is assumed…

IEC 63132-6:2023 is to establish, in a general way, suitable procedures and tolerances for the installation of Pelton vertical turbines. This document presents a typical assembly and whenever the word "turbine" is used in this document, it refers to a vertical Pelton turbine. There are many possible ways to assemble a unit. The size of the machine, the design of the machine, the layout…
