IEC 60675-3:2020 applies to electric direct-acting room heaters. This document defines performance characteristics related to the radiant effect and specifies methods for measuring the radiation efficiency for the information of users. This document is used to measure the radiation efficiency of direct-acting room heaters. This International Standard is to be used in conjunction with IEC 60675…

This document describes and classifies a range of laboratory ignition sources for use in fire tests on plastics and products consisting substantially of plastics. These sources vary in intensity and area of impingement. They are suitable for use to simulate the initial thermal abuse to which plastics are potentially exposed in certain actual fire risk scenarios. This compilation of standard…

IEC 61851-25:2020 applies to the DC EV supply equipment for charging electric road vehicles with a rated supply voltage of up to 480 V AC or up to 600 V DC, with rated output voltage not exceeding 120 V DC and output currents not exceeding 100 A DC. This document provides the requirements for the DC EV supply equipment where the secondary circuit is protected from the primary circuit by…

1 Scope 1.1 This National Standard of Canada1 provides additional information to CAN/CGSB-32.310, Organic production systems — General principles and management standards, in the form of permitted substances to be used as annotated in accordance with the scope of the table in which they are listed. Use of a listed substance in a manner inconsistent with the scope of the table in which it…

This Standard applies to any drinking water system component that conveys or dispenses water for human consumption through drinking or cooking.

1 Scope 1.1 This standard applies to suit systems to be worn by helicopter passengers during transportation over water where thermal protection may be required. 1.2 The primary function of a suit system meeting this standard is to provide the helicopter passenger protection from the effects of cold water during the initial hours of immersion. 1.3 Helicopter passenger transportation suit…

1.2 Scope 1.2.1 Description This standard applies to those devices classified as chemical dispensing systems and shall be protected by an air gap complying to ASME A112.1.3-2000 (R2015), an integral elastomer gap, or an Atmospheric Vacuum Breaker (AVB). If an AVB is used as its method of backflow protection, it must conform with ASSE 1001 or CSA B64.1.1. 1.2.2 Pressure Range Devices…

1 Scope 1.1 This Standard specifies requirements for measuring the heat recovery efficiency and pressure loss for drain water heat recovery (DWHR) units. 1.2 This Standard applies to DWHR units a) of any size; and b) with a configuration where potable water and drain water flow rate is equal; 1.3 In this Standard, “shall” is used to express a requirement, i.e., a provision that the user…

1 Scope 1.1 This Standard specifies requirements for the durability and safety of drain water heat recovery (DWHR) units. 1.2 This Standard applies to DWHR units of any diameter and length and configuration for use with potable water, and to their components and materials supplied by the manufacturer, their assembly and installation instructions, and their operation after assembly in…

1 Scope 1.1 This Standard covers mechanical couplings that are used to axially join pipes and fittings in non-pressure drain, waste, and vent (DWV) piping systems and sewer piping systems located inside or outside buildings and above ground or underground. Notes: 1) Caution should be exercised when installing mechanical couplings at low temperatures. The coupling manufacturer should be…
