Proportional Flow Control Devices are commonly found in European hydronic systems. Typically, these product are installed as a part of an integrated system to balance flow into both sides of a double-wall heat exchanger. One...

1.1 Facilities and workplaces impacted This Standard identifies the requirements for a PSM system for facilities and worksites handling or storing materials that are potentially hazardous, either due to an inherent chemical...

Note: Le champ de cet avis d’intention (publié pour la première fois le 1 mars 2022) a été mis à jour par l’OEN responsable le 21 avril 2022. This document specifies tests and requirements for the check valve, a liquefied...

This part of IEC 61000 is concerned with conducted disturbances in the frequency range from 0 kHz to 9 kHz. It gives numerical compatibility levels for industrial and non-public power distribution systems at nominal voltages...

This part of IEC 61000 provides guidance on principles which can be used as the basis for determining the requirements for the connection of unbalanced installations (i.e. three-phase installations causing voltage unbalance)...

This part of IEC 61000 relates to the immunity requirements, test methods, and range of recommended test levels for equipment to unidirectional surges caused by overvoltages from switching and lightning transients. Several...

1.1 This Standard applies to surge protective devices (SPDs) intended for: a) permanently connected applications designed for limiting surge voltages and discharging surge currents; b) use on 50/60 Hz circuits over 42 V and...

1.1 This Standard covers cord connected, direct plug-in and receptacle type SPDs whose primary function is to provide surge protection and that are intended to be marked SPD Type 3 in accordance with Clause 5.2 a). This...

The objective would be to update CSA 743 to align with AHRI 551/591 SI Standard, AHRI 561 and ASHRAE 90.1 efficiency requirements. Would recommend the efficiency requirements be moved to an appendix thus making it easier to...

The water treatment systems covered in this standard shall be self-regeneration anion exchange systems designed to reduce nitrate from drinking water. The systems shall use anion exchange media that prevents nitrate dumping...

1.1 General This Standard covers the test requirements used to measure battery charger energy consumption for battery chargers intended to be operated from 115 V ac, 60 Hz line voltage connected by plug to wall receptacles or...
