This standard covers the requirements for the design, installation, operation, maintenance and the safety of Household Biogas Systems (HBSs), producing biogas in an amount equivalent to an installation capacity of less than 100 MPW per year.

The standard applies to HBSs comprising of pipeline and equipment with pressure levels of less than 5 kPa.

Any equipment or appliances connected to an HBS or utilizing the biogas energy of an HBS are not a part of the scope of this standard.

This document specifies the minimum nuclear criticality safety training requirements for Operations Staff, Operations Supervisors, and Management. The requirement for the training of Operations Staff, Operations Supervisors and Management is identified in ISO–1709.

This document is applicable to areas, processes or facilities containing quantities of fissile nuclides in which nuclear criticality safety is required to be established, except for nuclear reactors where the core is fully loaded.

This document is not applicable to the transport of fissile materials outside the boundaries of nuclear establishments, nor for the response to a criticality accident. Training for response to a criticality accident is considered in ISO-11320.

This document specifies requirements for the ice plug technique with liquid nitrogen or dry ice as refrigerant (cryogenic medium) on metal pipes of nuclear power plants. The freezing liquid can be water or water mixture (e.g. boric acid mixture).

This document specifies technical requirements of ice plug generation, formation judgment and removal, measures before, during and after ice plugging and requirements for personnel and non-destructive testing.

This document is applicable for maintenance work, modification work and test inspections work when no other locking opportunity than ice plugging is available.

The application of the ice plug isolation technique is principally not allowed on cladded pipes or pipes with internal coatings. The application for pressure test is not in the scope of this document and should be qualified separate.

This document specifies requirements for competence, consistency and impartiality in the auditing and certification of ISO 50001 energy management systems (EnMS) for bodies providing these services. In order to ensure the effectiveness of EnMS auditing, this document addresses the auditing process, competence requirements for personnel involved in the certification process for energy management systems, the duration of audits and multi-site sampling.

This document specifies requirements for a valuation of energy related investments (VALERI). It provides a description on how to gather, calculate, evaluate and document information in order to create solid business cases based on Net Present Value calculations for ERIs. The standard is applicable for the valuation of any kind of energy related investment. The document focusses mainly on the valuation and documentation of the economical impacts of ERIs. However, non-economical effects (e.g. noise reduction) that may occur through undertaking an investment are considered as well. Thus, qualitative effects (e.g. impact on the environment)– even if they are non-monetisable – are taken into consideration.

This document specifies the requirements, common methodology and deliverables for energy audits. It applies to all forms of establishments and organizations, all forms of energy and uses of energy. This document covers the general requirements common to all energy audits. Specific energy audit requirements complete the general requirements in separate parts dedicated to energy audits for buildings, industrial processes and transport.

This document is applicable to specific energy audit requirements in buildings. It specifies the requirements, methodology and deliverables of an energy audit in a building or group of buildings, It is applied in conjunction with, and is supplementary to, EN 16247-1, Energy audits — Part 1: General requirements. It provides additional requirements to EN 16247-1 and is applied simultaneously.

If processes are included in the scope of the energy audit, the energy auditor can choose to apply EN 16247-3, Energy audits — Part 3: Processes. If on-site transport on a site is included in the scope of the energy audit, the energy auditor can choose to apply EN 16247-4, Energy audits — Part 4: Transport.

This document specifies the requirements, methodology and deliverables of an energy audit within a process. These consist of:

a) organizing and conducting an energy audit;

b) analysing the data from the energy audit;

c) reporting and documenting the energy audit findings.

This part of the standard applies to sites where the energy use is due to process. It is used in conjunction with and is supplementary to EN 16247-1, Energy audits — Part 1: General requirements. It provides additional requirements to EN 16247-1 and is applied simultaneously.

A process could include one or more production lines, offices, laboratories, research centres, packaging and warehouse sections with specific operational conditions and site transportation. An energy audit could include the whole site or part of a site.

If buildings are included in the scope of the energy audit, the energy auditor may choose to apply EN 16247-2, Energy Audits — Part 2: Buildings. If on-site transport on a site is included in the scope of the energy audit, the energy auditor may choose to apply EN 16247-4, Energy audits — Part 4: Transport.

NOTE The decision to apply Parts 2 and 4 could be made during the preliminary contact, see 5.1.

This document is used in conjunction with and is supplementary to EN 16247-1, Energy audits — Part 1: General requirements. It provides additional requirements to EN 16247-1 and is applied simultaneously.

The procedures described here apply to the different modes of transport (road, rail, marine and aviation), as well as the different ranges (local- to long-distance) and what is transported (i.e. goods and people).

This document specifies the requirements, methodology and deliverables specific to energy audits in the transport sector, every situation in which a displacement is made, no matter who the operator is (a public or private company or whether the operator is exclusively dedicated to transport or not), is also addressed in this document.

This document advises on both the optimization of energy within each mode of transport, as well as selecting the best mode of transport in each situation; the conclusions drawn by the energy audit can influence decisions on infrastructure and investment e.g. in teleconferencing or web meetings.

Energy audits of buildings and processes associated with transport can be conducted respectively with the EN 16247-2 Buildings and EN 16247-3 Processes e.g. pipelines, depots and escalators/travelators. This part of the standard does not include the infrastructure which supplies energy e.g. the electricity generation of energy for railways.

This European Standard defines the minimum requirements to ensure the interoperability of public hydrogen refuelling points including refuelling protocols that dispense gaseous hydrogen to road vehicles (e.g. Fuel Cell Electric Vehicles).

The safety and performance requirements for the entire hydrogen refuelling station (HRS), addressed in accordance with existing relevant European and National legislation, are not included in this European Standard.

NOTE Guidance on considerations for hydrogen refuelling stations (HRS) is provided in ISO/TS 19880-1.
