Scope This National Standard specifies minimum requirements for preparing, developing, and conducting challenge-based, agile and open procurement of digital products and services. This Standard defines a framework for organizations evaluating the suitability of digital product and service providers using “challenge-based” criteria. This methodology requires organizations sourcing digital,…

1 Scope 1.1 Purpose The purpose of this Standard is to minimize the risk of personal injury by providing minimum requirements for the design, construction, installation, inspection, and maintenance of the mechanical refrigeration systems and volatile direct refrigeration systems specified in Clauses 1.2.1and 1.2.2. Note: This Standard does not directly address protection of property and…

This standard specifies the characteristics of biomethane at the injection point in the natural gas distribution or transmission system to ensure its compatibility with the characteristics of the natural gas present in the system into which it is injected. It applies to biomethane produced from biogas derived from anaerobic decomposition, no matter the source of the organic material. NOTE —…

Scope 1.1 This Standard sets forth the minimum requirements for containment sumps, and associated sump fittings and accessories (products) intended for below-grade, or at-grade, or above-grade use as an enclosure for the housing of, and access to, underground piping, connector piping, and other fueling system components (such as pumps, valves, sensors, wiring, etc.), in addition to temporary…

This document specifies methods for the measurement of the absorbed-dose rate in a tissue-equivalent slab phantom in the ISO 6980 reference beta-particle radiation fields. The energy range of the beta-particle-emitting isotopes covered by these reference radiations is 0,22 MeV to 3,6 MeV maximum beta energy corresponding to 0,07 MeV to 1,2 MeV mean beta energy. Radiation energies outside this…

This document specifies the technical delivery requirements for round and flat bars and wire rods manufactured from the alloyed steels listed in Table 4, intended for hot-formed and subsequently heat-treated springs or cold-formed and subsequently heat-treated springs. The products are supplied in one of the heat-treatment conditions given for the different types of products in Table 2 and in one…

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…

This document specifies how a preliminary welding procedure specification (pWPS) is qualified by welding procedure tests. This document defines the conditions for the execution of welding procedure tests and the range of qualification for welding procedures for all welding operations within the qualification of this document. Two classes of welding procedure tests are given in order to permit…

This document specifies the requirements of safety management systems for application services provided by service robots [application service safety management system (hereafter ASSMS)] that an application service provider can use for the safety of its users and its third parties when it provides application service in unstructured human spaces with trained and untrained persons (e.g. giving…
