ISO 16346:2013 sets out ways of expressing the energy performance in an energy performance certificate of a building (including the technical building systems) and ways of expressing requirements as to the energy performance. This includes an overall numerical energy performance indicator and classes against benchmarks. ISO 16346:2013 additionally includes numerical indicators at system or…

IEC 60627:2013 is applicable to anti-scatter grids used in medical diagnostic X-ray imaging equipment. Anti-Scatter Grids are used to reduce the incidence of scattered radiation, produced particularly in the body of the patient, upon the image reception area and thus to improve the contrast of the X-ray pattern. This International Standard specifies the definitions, determination and indication…

IEC 61472:2013 describes a method for calculating the minimum approach distances for live working, at maximum voltages between 72,5 kV and 800 kV. This standard addresses system overvoltages and the working air distances or tool insulation between parts and/or workers at different electric potentials. The required withstand voltage and minimum approach distances calculated by the method described…

IEC/TR 61850-90-7:2013(E) describes the functions for power converter-based distributed energy resources (DER) systems, focused on DC-to-AC and AC-to-AC conversions and including photovoltaic systems (PV), battery storage systems, electric vehicle (EV) charging systems, and any other DER systems with a controllable power converter. It defines the IEC 61850 information models to be used in the…

Scope 1.1 Purpose This Standard specifies technical requirements on how to make buildings and the exterior built environment accessible and safely usable by persons with physical, sensory, or cognitive disabilities. Commentary: (1) Temporary buildings and facilities provided for public use should also comply with the technical requirements of this Standard. Such temporary facilities may…

1 Scope 1.1 These requirements cover single pole locking-type separable attachment plugs, cord connectors, panel inlets, and panel outlets, adapters, and accessories, rated up to a maximum of 800 amperes and up to 600 volts ac or dc and not intended for connection or disconnection under load conditions. 1.2 These devices are intended to provide power from feeders or branch circuits, or…

1 Scope 1.1 This Standard specifies performance, design, testing, marking, classification, and other requirements related to anchorage connectors in travel restraint, fall arrest, work positioning, and suspended component/tie-back line systems. 1.2 The requirements of this Standard include (where applicable) anchorage connectors attached to an anchorage. Methods of verifying the actual strength…

ISO 21542:2011 specifies a range of requirements and recommendations for many of the elements of construction, assemblies, components and fittings which comprise the built environment. These requirements relate to the constructional aspects of access to buildings, to circulation within buildings, to egress from buildings in the normal course of events and evacuation in the event of an emergency.…

1 Scope 1.1 This Guideline provides direction for the application of exemption quantity and clearance level criteria for the release of materials containing, or potentially containing, radioactive nuclear substances, and the activities necessary to demonstrate compliance with these criteria. Specifically, this Guideline addresses clearance of materials that are regulated by the Nuclear…

201.1 Scope, object and related standards Clause 1 of the general standard1) applies, except as follows: 201.1.1 Scope Replacement: This International Standard applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of ELECTRON ACCELERATORS, hereafter referred to as ME EQUIPMENT, in the range 1 MeV to 50 MeV, used for treatment of PATIENTS. This particular standard, with the…
