This document addresses some of the security requirements in the areas of authentication and other security services through the provision of a set of frameworks upon which full services can be based. Specifically, this Recommendation | International Standard defines frameworks for: ? public-key certificates; and ? attribute certificates. The public-key certificate framework defined in…

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…

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…

1 Scope 1.1 This Standard provides requirements for grade-level, in-ground enclosures. The enclosures are made of polymer concrete, composite, or plastic (enclosure covers may be made of metal), intended for conductors and connections at voltages 750 V or less. 1.2 These enclosures are not intended to be installed where vehicular traffic normally occurs. 1.3 These enclosures are intended to…

1 Scope This document specifies principles and requirements and provides guidance at the project level for the quantification, monitoring and reporting of activities intended to cause greenhouse gas (GHG) emission reductions or removal enhancements. It includes requirements for planning a GHG project, identifying and selecting GHG sources, sinks and reservoirs (SSRs) relevant to the project and…

1 Scope This document specifies principles and requirements and provides guidance for verifying and validating greenhouse gas (GHG) statements. It is applicable to organization, project and product GHG statements. The ISO 14060 family of standards is GHG programme neutral. If a GHG programme is applicable, requirements of that GHG programme are additional to the requirements of the ISO 14060…
