This document provides a transparent framework for reporting on the choices related to the procedure to determine PEFs and CO2 Emission coefficients for energy delivered to and/or exported by the buildings as described in EN ISO 52000-1:2017. Exported PEFs and CO2 Emission coefficients can be different from those chosen for delivered energy. This document can be considered as a supporting/complementing standard to EN ISO 52000-1, as the latter requires values for the PEFs and GHG Emissions factors to complete the EPB calculation. Table 1 shows the relative position of this document within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000-1.

This document specifies a method for the determination of the ultimate anoxic biodegradability of plastics made of organic compounds, where the amount of the produced nitrogen and carbon dioxide at the end of the test is measured. The test substance is exposed to an inoculum stemming from the denitrification tank of a wastewater treatment plant. Testing is performed under defined laboratory conditions.

This document specifies the procedure for classification of the resistance to fire performance of construction products and building elements used as components of building service installations, using data from fire resistance tests which are within the direct field of application of the relevant test method. Classification on the basis of extended application of test results is also included in the scope of this document. Products/elements for use in ventilation systems include (excluding smoke and heat exhaust ventilation): - fire resisting ducts; - fire dampers. Products /elements for use in/as cables systems: - Intrinsic fire resistant cables/unprotected cables; - Fire protective systems for cable systems; - Supporting /suspension devices; - Associated components (connectors, glands, junctions, etc.) Relevant test methods which have been prepared for these products/elements are listed in Clause 2.

This document specifies methods for flame tests to be applied to respiratory protective devices.

This European standard specifies oxygen reduction systems that are used as fire prevention systems by creating an atmosphere in an area which is having a lower permanent oxygen concentration as in ambient conditions. The level of oxygen reduction is defined by the individual risks of these areas (see Annex A). Oxygen reduction is achieved by technical systems which are providing a flux of air containing a reduced concentration of oxygen. This European standard specifies minimum requirements and defines the specifications governing the design, installation and maintenance of fixed oxygen reduction systems with oxygen reduced air in buildings and industrial production plants. The standard also applies to the extension and modification of existing systems. This European standard applies to oxygen reduction systems using nitrogen which are designed for continual oxygen reduction in enclosed spaces. NOTE Nitrogen is today the most suitable gas to be used for oxygen reduction. For other gases this European standard can be used as basis. This European standard does not apply to oxygen reduction systems that use water mist or combustion gases. The European standard does not apply to: - explosion suppression systems; - explosion prevention systems; - fire extinguishing systems using gaseous extinguishing agents; - inertization of portable containers; - systems in which oxygen levels are reduced for reasons other than fire prevention (e.g. steel processing in the presence of inert gas to avoid the formation of oxide film); - inerting required during repair work on systems or equipment (e.g. welding) in order to eliminate the risk of fire or explosion. In addition to the conditions for the actual oxygen reduction system and its individual components this European standard also covers certain structural specifications for the protected area. The space protected by an oxygen reduction system is a controlled and continuously monitored indoor climate for extended occupation. This standard does not cover unventilated confined spaces that may contain hazardous gases.
