This document specifies the test gases, test pressures and categories of appliances relative to the use of gaseous fuels of the first, second and third families. It serves as a reference document in the specific standards for appliances that fall within the scope of the Council Directive on the approximation of the laws of Member States concerning gas appliances 2009/142/EC.
The standard makes recommendations for the use of the gases and pressures to be applied for the tests. The full procedure will be given in the corresponding appliance standards.
NOTE   The test gases and the test pressures specified in this standard are in principle intended to be used with all the appliances in order to establish conformity with the corresponding standards.
However, the use of some test gases and test pressures may not be appropriate in the following cases:
-   appliances with nominal heat input greater than 300 kW;
-   appliances constructed on site;
-   appliances in which the final design is influenced by the user;
-   appliances constructed for use with high supply pressures (notably direct use of the saturated vapour pressure).
In these cases, the specific appliance standards may specify other test conditions in order to establish compliance with their requirements.

– the plant safety requirements and the architecture of the overall Electrical Power
System and its sub-systems (see Figure 1) including:
a) the contribution to the plant Defence in Depth;
b) the independency and redundancy provisions;
– the electrical requirements and the architecture of the Electrical Power System and its
sub-systems;
– the functional requirements and the architecture of the Electrical Power System and its
sub-systems;
– the requirements associated with the maintenance strategy and the architecture of the
Electrical Power System and its sub-systems;
• the design of Electrical power sub-systems (e.g. interruptible and uninterruptible);
• the requirements for supporting systems of Electrical Power System (HVAC, I&C, etc.);
• the Electrical Power System life-cycle framework.

This document lays down requirements for the design qualification of terrestrial photovoltaic
modules suitable for long-term operation in open-air climates. The useful service life of
modules so qualified will depend on their design, their environment and the conditions under
which they are operated. Test results are not construed as a quantitative prediction of module
lifetime. In climates where 98th percentile operating temperatures exceed 70 °C, users are
recommended to consider testing to higher temperature test conditions as described in
IEC TS 63126.
Users desiring qualification of PV products with lesser lifetime expectations are recommended
to consider testing designed for PV in consumer electronics, as described in IEC 63163
(under development). Users wishing to gain confidence that the characteristics tested in
IEC 61215 appear consistently in a manufactured product may wish to utilize IEC 62941
regarding quality systems in PV manufacturing.
This document is intended to apply to all crystalline silicon terrestrial flat plate modules.
This document does not apply to modules used with concentrated sunlight although it may be
utilized for low concentrator modules (1 to 3 suns). For low concentration modules, all tests
are performed using the irradiance, current, voltage and power levels expected at the design
concentration.
The objective of this test sequence is to determine the electrical characteristics of the module
and to show, as far as possible within reasonable constraints of cost and time, that the
module is capable of withstanding prolonged exposure outdoors. Accelerated test conditions
are empirically based on those necessary to reproduce selected observed field failures and
are applied equally across module types. Acceleration factors may vary with product design
and thus not all degradation mechanisms may manifest. Further general information on
accelerated test methods including definitions of terms may be found in IEC 62506.
Some long-term degradation mechanisms can only reasonably be detected via component
testing, due to long times required to produce the failure and necessity of stress conditions
that are expensive to produce over large areas. Component tests that have reached a
sufficient level of maturity to set pass/fail criteria with high confidence are incorporated into
the IEC 61215 series via addition to Table 1 in IEC 61215-1:2021. In contrast, the tests
procedures described in this series, in IEC 61215-2, are performed on modules.
This document defines PV technology dependent modifications to the testing procedures and
requirements per IEC 61215-1:2021 and IEC 61215-2:2021.

The object of this qualification standard is to determine the optoelectronic, mechanical, thermal,
and processing characteristics of CPV cells and CoCs to show that they are capable of
withstanding assembly processes and CPV application environments. The qualification tests of
this document are designed to demonstrate that cells or CoCs are suitable for typical assembly
processes, and when properly assembled, are capable of passing IEC 62108.
This document defines qualification testing for two levels of concentrator photovoltaic device
assembly:
a) cell, or bare cell; and
b) cell on carrier (CoC).
NOTE Note that a variety of alternate names are used within the industry, such as solar cell assembly, receiver,
etc.

This document lays down requirements for the design qualification of terrestrial photovoltaic
modules suitable for long-term operation in open-air climates. The useful service life of
modules so qualified will depend on their design, their environment and the conditions under
which they are operated. Test results are not construed as a quantitative prediction of module
lifetime.
In climates where 98th percentile operating temperatures exceed 70 °C, users are
recommended to consider testing to higher temperature test conditions as described in
IEC TS 63126. Users desiring qualification of PV products with lesser lifetime expectations
are recommended to consider testing designed for PV in consumer electronics, as described
in IEC 63163 (under development). Users wishing to gain confidence that the characteristics
tested in IEC 61215 appear consistently in a manufactured product may wish to utilize
IEC 62941 regarding quality systems in PV manufacturing.
This document is intended to apply to all thin-film CdTe based terrestrial flat plate modules.
As such, it addresses special requirements for testing of this technology supplementing
IEC 61215-1:2021 and IEC 61215-2:2021 requirements for testing.
This document does not apply to modules used with concentrated sunlight although it may be
utilized for low concentrator modules (1 to 3 suns). For low concentration modules, all tests
are performed using the irradiance, current, voltage and power levels expected at the design
concentration.
The object of this test sequence is to determine the electrical characteristics of the module
and to show, as far as possible within reasonable constraints of cost and time, that the
module is capable of withstanding prolonged exposure outdoors. Accelerated test conditions
are empirically based on those necessary to reproduce selected observed field failures and
are applied equally across module types. Acceleration factors may vary with product design
and thus not all degradation mechanisms may manifest. Further general information on
accelerated test methods including definitions of terms may be found in IEC 62506.
Some long-term degradation mechanisms can only reasonably be detected via component
testing, due to long times required to produce the failure and necessity of stress conditions
that are expensive to produce over large areas. Component tests that have reached a
sufficient level of maturity to set pass/fail criteria with high confidence are incorporated into
the IEC 61215 series via addition to Table 1 in IEC 61215-1. In contrast, the tests procedures
described in this series, in IEC 61215-2, are performed on modules.
This document defines PV technology dependent modifications to the testing procedures and
requirements per IEC 61215-1:2021 and IEC 61215-2:2021.

This International Standard describes methods for establishing seismic qualification procedures
that will yield quantitative data to demonstrate that the equipment can meet its performance
requirements. This document is applicable to electrical, mechanical, instrumentation and control
equipment/components that are used in nuclear facilities. This document provides methods and
documentation requirements for seismic qualification of equipment to verify the equipment’s
ability to perform its specified performance requirements during and/or after specified seismic
demands. This document does not specify seismic demand or performance requirements. Other
aspects, relating to quality assurance, selection of equipment, and design and modification of
systems, are not part of this document. As seismic qualification is only a part of equipment
qualification, this document is used in conjunction with IEC/IEEE 60780-323.
The seismic qualification demonstrates equipment’s ability to perform its safety function(s)
during and/or after the time it is subjected to the forces resulting from at least one safe shutdown
earthquake (SSE/S2). This ability is demonstrated by taking into account, prior to the SSE/S2,
the ageing of equipment and the postulated occurrences of a given number of lower intensity
operating basis earthquake (OBE/S1). Ageing phenomena to be considered, if specified in the
design specification, are those which could increase the vulnerability of equipment to vibrations
caused by an SSE/S2.

IEC 62934:2021 provides terms and definitions in the subject area of grid integration of renewable energy generation. The technical issues of grid integration mainly focus on the issues caused by renewable energy generation with variable sources and/or converter based technology, such as wind power and photovoltaic power generation. Some renewable energy generations such as hydro power and biomass power with a relatively continuously available primary energy source and a rotating generator are conventional sources of generation, and are therefore not covered in this document.
The intention of this document is to answer the question "what do the words mean" and not "under what conditions do the terms apply".

The present document is aimed at defining the topology and level of analysis to assess the energy efficiency of mobile
networks. Within the scope of the present document there is the radio access part of the mobile networks, and namely
there are radio base stations, backhauling systems, radio controllers and other infrastructure radio site equipment. The
covered technologies are GSM, UMTS, LTE and 5G New Radio (NR). In particular the present document defines
metrics for mobile network energy efficiency and methods for assessing (and measuring) energy efficiency in
operational networks. The purpose of the present document is to allow better comprehension of networks energy
efficiency, in particular considering the networks' evolution in different periods in time.
Aiming to consider also the slicing approach of the networks from 5G onwards the metrics are extended to the latency
of the network itself related to the energy consumed, additionally to the metrics based on traffic and on coverage,
already existing for legacy networks and still valid.
The present document deals with both a homogeneous and heterogeneous "network" considering a network whose size
and scale could be defined by topologic, geographic or demographic boundaries. For networks defined by topologic
boundaries, a possible example of a network covered by the present document consists of a control node (whenever
applicable), its supported access nodes as well as the related network elements. Networks could be defined by
geographic boundaries, such as city-wide, national or continental networks and could be defined by demographic
boundaries, such as urban or rural networks.
The present document applies to the so-called "partial" networks for which a measurement method is also
recommended. The specification extends the measurements in partial networks to wider so-called "total" networks
energy efficiency estimations (i.e. the network in a geographic area, the network in a whole country, the network of a
MNO, etc.).
Terminal (end-user) equipment is outside the scope of the present document and is not considered in the energy
efficiency measurement.

This document describes the ceramographic preparation of uranium dioxide (UO2) sintered pellets for qualitative and quantitative microstructure examinations.
These examinations can be carried out before and after thermal or chemical etching.
They enable
— observations of fissures, inter- or intra-granular pores and inclusions, and
— measurement of pore and grain size and measurement of pore and grain size distributions.
The measurement of average grain size can be carried out using a classical counting method as described in ISO 2624 or ASTM E112[3], i.e. intercept procedure, comparison with standard grids or reference photographs.
The measurement of pore-size distributions is usually carried out by an automatic image analyser. If the grain-size distributions are also measured with an image analyser, it is recommended that thermal etching be used to reveal the grain structure uniformly throughout the whole sample.

This document specifies gas leakage test criteria and test methods for demonstrating that packages used to transport radioactive materials comply with the package containment requirements defined in the International Atomic Energy Agency (IAEA) Regulations for the Safe Transport of Radioactive Material for:
— design verification;
— fabrication verification;
— preshipment verification;
— periodic verification;
— maintenance verification.
This document describes a method for relating permissible activity release of the radioactive contents carried within a containment system to equivalent gas leakage rates under specified test conditions. This approach is called gas leakage test methodology. However, in this document it is recognized that other methodologies might be acceptable, provided that they demonstrate that any release of the radioactive contents will not exceed the regulatory requirements, and subject to agreement with the competent authority.
This document provides both overall and detailed guidance on the complex relationships between an equivalent gas leakage test and a permissible activity release rate. Whereas the overall guidance is universally agreed upon, the use of the detailed guidance shall be agreed upon with the competent authority during the Type B(U), Type B(M) or Type C packages certification process.
It should be noted that, for a given package, demonstration of compliance is not limited to a single methodology.
