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…

Objet La présente Norme nationale du Canada définit les exigences relatives à l’équipement, aux critères de rendement, à la procédure à suivre et aux méthodes d’essai pour la mise en place de systèmes de récupération des vapeurs (SRV) dans les réseaux de distribution d’essence comprenant des terminaux, des dépôts routiers, des stations-service et des camions-citernes qui sont couramment…

This document gives guidelines for organizations on how to prevent or control exposure to infectious agents at the workplace and manage the risks associated with infectious diseases that: —    present a risk of severe ill health or death and can impact the health, safety and well-being of workers and other relevant interested parties; —    present a lower risk to health yet have a significant…

This document establishes a method to determine and assess sound insulation performances of all transparent, translucent and opaque glass products, for basic, special basic or processed glass products, when intended to be used in glazed assemblies in buildings, and which exhibit properties of acoustic protection, either as a prime or supplementary characteristic. This document refers to…

IEC 60437:2023 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 60437:2023 edition 3.0 and the previous IEC 60437:1997 edition 2.0. Furthermore, comments from IEC TC 36 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content…

IEC 60437:2023 specifies the procedure for a radio interference (RI) test carried out in a laboratory on clean and dry insulators at a frequency of 0,5 MHz or 1 MHz or, alternatively, at other frequencies between 0,5 MHz and 2 MHz. This document applies to insulators for use on AC or DC overhead power lines and overhead traction lines with a nominal voltage greater than 1 000 V. This third…

Scope 1.1 This Standard provides minimum requirements for the security of premises from intrusion and infiltration, as well as considerations for secure access and safe egress. 1.2 This Standard provides the criteria for the installation, maintenance, and testing of physical and electronic premises security systems designed to prevent and detect intrusion into the protected premises by…

This document specifies a laboratory test method for measuring perceived air quality using human subjects that can be used for assessing the performance of air cleaners removing gas-phase pollutants. The method describes the performance of gas-phase air cleaners with respect to removal of pollutants that can be sensed by human subjects. The method has a reference to sensory tests specified in ISO…

Scope 1.1 These requirements apply to portable germicidal equipment intended to expose the air and surfaces within an unoccupied area with uncontained ultraviolet (UV) energy. These requirements address equipment intended to remain stationary while in operation, and intended for use by ordinary persons. The equipment may also produce visible light. 1.2 In this Standard, the UV overexposure…

Scope 1.1 These requirements apply to ultraviolet germicidal irradiation (UVGI) equipment and systems intended for installation and use in accordance with the U.S. National Electrical Code (NEC), NFPA 70 and in accordance with the Canadian Electrical Code, Part I (CEC), CSA C22.1. These requirements cover: a) UV Germicidal Equipment – These devices emit uncontained UV energy into the…
