IEC 63522-15:2024 is used for testing electromechanical elementary relays (electromechanical relays, reed relays, reed contacts, reed switches and technology combination of these) and evaluates their ability to perform under expected conditions of transportation, storage and all aspects of operational use.
This document defines a standard test method that applies defined loads to relay terminals (direct axial pulls, bending or twisting) as they can be present in assembled configurations or during handling. In addition, it covers torque stress for nuts and threaded terminals as they are likely to be experienced during normal assembly operations.

IEC 63522-17:2024 is used for testing electromechanical elementary relays (electromechanical relays, reed relays, reed contacts, reed switches and technology combination of these) and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use.
This document defines a standard test method to simulate the mechanical stress on relays as it can occur in service, during handling or during transportation. This document comprises test procedures to simulate shock impacts, steady acceleration environments (such as moving vehicles, aircraft and projectiles) as well as vibration conditions.

IEC 63522-13:2024 is used for testing electromechanical elementary relays (electromechanical relays, reed relays, reed contacts, reed switches and technology combinations of these) and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use.
This document defines a standard test method to simulate impacts of sulfuric atmospheres to relays. The test conditions simulate an artificial situation and allow a performance comparison for usability of the devices under test (DUT) with regard to known and existing switching solutions.
The test is a static test without actual operation of the DUT to simulate a worst-case scenario for corrosion, since corrosion increases over time. The corrosion layer can potentially create contact sticking, increase resistance or other undesired effects in the relay. Those aspects can be affected by DUT actuations during the test, which can destroy the corrosion layers or hide relevant long-term effects.
In addition to polluted atmospheres, the suitability of the DUT for use and/or storage in corrosive atmospheres can be assessed in a salt-laden atmosphere as described in IEC 63522-44.

This document specifies the main characteristics of the voltage at a network user's supply terminals in public low voltage, medium, high, and extra-high voltage AC electricity networks under normal operating conditions. This document specifies the limits or values within which the voltage characteristics can be expected to remain at any supply terminal in public European electricity networks, only. Industrial networks are excluded from the scope of EN 50160. NOTE 1 If non-public networks (e.g. residential quarters, energy communities, office centres, shopping centres) have similar end-users as public networks, it is strongly advised to apply the same requirements as for public networks. This document does not apply under abnormal operating conditions, including the following: a) a temporary supply arrangement to keep network users supplied during conditions arising as a result of a fault, maintenance and construction work, or to minimize the extent and duration of a loss of supply; b) in the case of non-compliance of a network user's installation or equipment with the relevant standards or with the technical requirements for connection, established either by the public authorities or the network operator, including the limits for the emission of conducted disturbances; NOTE 2 A network user’s installation can include load and generation. c) in exceptional situations, in particular: 1) exceptional weather conditions and other natural disasters; 2) third party interference; 3) acts by public authorities, 4) industrial actions (subject to legal requirements); 5) force majeure; 6) power shortages resulting from external events. The voltage characteristics given in this document refer to conducted disturbances in public electric power networks. They are not intended to be used as electromagnetic compatibility (EMC) levels or product emission limits. Power quality is related to EMC in several ways – especially because compliance with power quality requirements depends on the control of cumulative effect of electromagnetic emissions from all/multiple equipment and/or installations. Therefore, the voltage characteristics given in this document gives guidance for specifying requirements in equipment product standards and in installation standards. NOTE 3 The performance of equipment might be impaired if it is subjected to supply conditions which are not specified in the equipment product standard. NOTE 4 This document can be superseded in total or in part by the terms of a contract between the individual network user and the network operator. The sharing of complaint management and problem mitigation costs between the involved parties is outside the scope of EN 50160.

This document provides a description of the main environmental sustainability issues that organisations
or individuals that are developing and/or using Artificial Intelligence (AI) consider, in particular, in the
context of the European energy systems and resources.
It is important to have a focus where AI helps in optimization and virtual deployment of engineering
solutions [1], especially in Europe with limited natural resources. This document reviews the European
AI landscape, with a context of environmental sustainability. This is addressed with a focus on Europeanspecific
aspects of AI demands for resources, as well as its potential to contribute to environmental
sustainability in Europe [2]. The document creates an inventory of impacts and techniques to support
environmentally sustainable use of AI, and an equitable access to computation resources.
Suggested improvements in AI resource management are focused on:
• reduction of the operational AI energy consumption (see section 5)
• reduction of other AI resource consumption (water, etc.) (see section 6)
The document also considers the potential benefits of using AI from a sustainability perspective. Methods
of measuring the environmental sustainability impacts of AI are also quantified.
This document is intended to help with the development of new standards and complement existing
European standards and standardization deliverables that define resource measurement for the use of
AI. It describes best practices and indicates which techniques and management processes for
improvement of AI resource performance and environmental viability. The document is expected to
contribute to voluntary corporate social responsibility (CSR) in Europe, and increase sustainability
awareness for individuals when designing, developing, and using AI. The aim is to create a focus on the
responsible use of AI that prioritizes ethical considerations, human values, and an understanding of the
social implications of AI design and use.
The document is aligned with equivalent activities in ISO/IEC/JTC 1/SC42/WG4, TR 20226 “Green and
Sustainable AI”, but takes into account specific aspects of the European energy system that are not

different categories of materials,
— the specimen directions in which the measurements should be performed,
— the volume of material examined in relation to the material grain size and the envisaged stress state,
— the selection of the stress-free reference (sample) facilitating the residual strain calculation, and
— the methods available for deriving residual stresses from the measured strain data.
Procedures are presented for calibrating synchrotron X-ray diffraction instruments, enabling:
— accurately positioning and aligning test pieces;
— precisely defining the volume of material sampled for the individual measurements;
and also for:
— making measurements;
— carrying out procedures for analysing the results;
— determining their uncertainties.
The principles of the synchrotron X-ray diffraction technique are described and put into perspective with
EN 15305:2008 and EN ISO 21432:2020, which are used to measure stresses in the bulk of a specimen.

This document specifies the requirements for the reconditioning and retesting of pressure relief valves (PRVs) for LPG pressure vessels covered under the scope of EN 14129.
This document applies to retesting and reconditioning of PRVs that are carried out in a workshop and does not apply to site adjustment of installed PRVs.
Annex A is a normative annex detailing a sampling approach for PRV requalification which could be used in case of on-site requalification of series produced pressure vessels fitted with series produced PRVs.

This document specifies robust Gaussian regression filters for the filtration of surface profiles. It defines,
in particular, how to separate large- and small-scale lateral components of surface profiles with protruding
dales and hills.
The concept presented for closed profiles are applicable to the case of roundness filtering. Where appropriate,
these concept can be extended to generalized closed profiles, especially for surface profiles with re-entrant
features.

This document is applicable to metallic valves as pressure accessories for industrial applications with a

This document specifies a manual reference method for the determination of the mass concentration of
specific elements in stationary source emissions. The method is applicable to each of the specific elements
in the concentration range of 0,005 mg/m3 to 5 mg/m3.
This document has been validated for the determination of the mass concentration of metals in
incineration exhaust gases – applying the performance criteria stated in Clause 9 – for the following
elements:
— arsenic (As), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), manganese (Mn), nickel (Ni),
lead (Pb), antimony (Sb), thallium (Tl), and vanadium (V) and their compounds.
The document can be used to determine metals other than those listed above (for example, selenium (Se)
(ISO 17211), tellurium (Te), beryllium (Be), tin (Sn) and zinc (Zn)).
NOTE 1 These other metals mentioned above are commonly required by National Regulations, but this
document currently has not yet been validated for these metals.
The document was validated for waste incinerators, but it is also applicable to other industrial processes,
the practical experience shows that it can be applied over wide concentration ranges and various
emission sources.
If mercury is intended to be determined as well, this can be sampled in a side stream arrangement of the
sampling train (EN 13211) [5].
NOTE 2 This document has been validated with the described materials, equipment, sampling, and digestion
performances etc., followed by analyses with atomic absorption spectroscopy (AAS) and inductively coupled plasma
optical emission spectroscopy (ICP-OES,) or inductively coupled mass spectrometry (ICP-MS). This does not exclude
the use of other types of equipment or analyses that meet the requirements and have been proven to be equivalent
to the described European Standard.

This document specifies requirements for the material, design, inspections, construction and workmanship,
manufacturing processes, and tests at manufacture of non-refillable metallic gas cylinders of welded, brazed,
or seamless construction. This document also specifies the requirements for the non-refillable sealing
devices and their methods of testing. It is applicable to non-refillable metallic gas cylinders for compressed
and liquefied gases.
NOTE The specific gases permitted in cylinders constructed to this document can be limited by national or
international requirements.
This document is applicable to cylinders where:
a) the test pressure does not exceed 250 bar1) (i.e. ph ≤ 250 bar) for liquefied gases and 450 bar for
compressed gases; or
b) the product of the test pressure and the water capacity does not exceed 1 000 bar·litres (i.e.
ph V ≤ 1 000 bar l); or
c) the test pressure exceeds 45 bar and the water capacity does not exceed 5 l (i.e. for ph > 45 bar, then
V ≤ 5 l).

This document provides rules for workplace sampling and the sample analysis for the determination and
characterization of airborne NOAA for electron microscopy and includes:
— the choice of appropriate samplers and their use for the determination and characterization (e.g.
classification of structures and morphology) of airborne NOAA using electron microscopic methods (SEM
and (S)TEM);
— counting rules and criteria for the determination and characterization (e.g. classification of structures,
chemical composition and morphology) of airborne NOAA using electron microscopic methods (SEM and
(S)TEM), especially for nanofibres and platelets.
This document is based on extensive laboratory tests for airborne NOAA, in particular those released during
the handling of engineered nanomaterials.
