This document specifies methods and procedures for determining the static performance of particulate
air filters used in air intake filter systems for rotary machinery such as stationary gas turbines,
compressors and other stationary internal combustion engines. It applies to air filters with an efficiency
of 85 % or more for the MPPS (EPA and HEPA filters) which are tested according to ISO 29463 (all parts)
and filters with a lower efficiency which are tested according to ISO 16890 (all parts). The procedures
described in both ISO 16890 (all parts) and ISO 29463 (all parts) are applied and extended by this
document to air filters which operate at flow rates within the range 0,24 m3/s (850 m3/h) up to
2,36 m3/s (8 500 m3/h).
Static filter systems normally use multiple stages of coarse, fine and optional EPA or HEPA filter elements
to protect the machinery. The scope of this document includes methods for performance testing of
individual filter elements. It does not include methods for the direct measurement of the performance
of entire systems as installed in service except in cases where they can meet the qualification criteria
for the test assembly. Nevertheless, cumulative filter efficiencies of multistage systems of fine filters
can be calculated by using the methods described in ISO 16890-1.
This document refers to static (barrier) filter systems but can also be applied to other filter types and
systems in appropriate circumstances, for example to evaluate the initial efficiency of cleanable and
surface loading filters.
The performance results obtained in accordance with this document cannot be quantitatively applied
(by themselves) to predict performance in service with regard to efficiency and lifetime

b) protection of machines against the harmful effects due to ingress of water;
c) protection of machines against the harmful effects due to ingress of dust.

Terms and definitions are relative to the brush construction (references 100’s to 500’s and parts of 900’s) and to the markings when operating on a rotating machine (references 600’s to 800’s). By extension, terms and definitions may be relevant for any kind of sliding electrical contacts for electrical machinery.

EN IEC 60034-18-41 defines criteria for assessing the insulation system of stator/rotor windings which are subjected to voltage-source pulse-width-modulation (PWM) drives. It applies to stator/rotor windings of single or polyphase AC machines with insulation systems for converter operation. It describes qualification tests and quality control (type and routine) tests on representative samples or on completed machines which verify fitness for operation with voltage source converters. This standard does not apply to: - rotating machines which are only started by converters; - rotating electrical machines with rated voltage ≤ 300 V r.m.s.; - rotor windings of rotating electrical machines operating at ≤ 200 V (peak).

IEC SRD 62913-2-1 2019 (E) initiates and illustrates the IEC’s systems approach based on Use Cases and involving the identification of generic smart grid requirements for further standardization work for grid related domains – i.e. grid management regrouping: transmission grid management, distribution grid management, microgrids and smart substation automation domains – based on the methods and tools developed in IEC SRD 62913-1.
The Grid management domain groups Use Cases and associated requirements common to the EHV, HV and MV/LV networks operations and the business analysis of the general electric network life cycle. Use Cases specific to parts of the general electric network are described in transmission grid management, distribution grid management, microgrids and smart substation automation clauses.
This document captures possible “common and repeated usage” of a smart grid system, under the format of “Use Cases” with a view to feeding further standardization activities. Use Cases can be described in different ways and can represent competing alternatives. From there, this document derives the common requirements to be considered by these further standardization activities in term of interfaces between actors interacting with the given system.
To this end, Use Case implementations are given for information purposes only. The interface requirements to be considered for later standardization activities are summarized (typically information pieces, communication services and specific non-functional requirements: performance level, security specification, etc.).

This part of IEC 60034 covers the procedures necessary to ensure the satisfactory repair, overhaul, and reclamation of all types and sizes of rotating electrical machines covered by the IEC 60034 series. The standard creates a generic industry procedure covering common aspects of a complete repair. The scope of work depends on the machine type, rating, condition, and the importance of plant reliability and safety. It includes - determining cause of failure, where necessary; - determining the extent of repair, as applicable; - defining revised performance, operating and ambient conditions, if required; - reviewing the original design, and upgrading the specification of the design, if required; - proving the quality and performance of the repaired machine, maintaining or improving the rated energy efficiency; - ensuring environmental considerations are taken into account. This document does not supersede the requirements prescribed in IEC 60079-19 or elsewhere concerning the repair and overhaul for machines used in explosive atmospheres. Machines for special applications such as hermetic, submersible, nuclear, hydrogen cooled machines, military, aviation and traction motors might have additional requirements, which are the subject of agreement between the service facility and user. This document is not intended to take the place of the original machine manufacturer’s instructions and recommendations. Re-designs and performance changes requiring machine designer input are beyond the scope of this document.

This part of IEC 60034 applies to three-phase synchronous machines of 1 kVA rating and
larger.
Most of the methods are intended to be used for machines having an excitation winding with
slip-rings and brushes for their supply. Synchronous machines with brushless excitation
require special effort for some of the tests. For machines with permanent magnet excitation,
there is a limited applicability of the described tests, and special precautions should be taken
against irreversible demagnetization.
Excluded are axial-field machines and special synchronous machines such as inductor type
machines, transversal flux machines and reluctance machines.
It is not intended that this document be interpreted as requiring any or all of the tests
described therein on any given machine. The particular tests to be carried out are subject to
agreement between manufacturer and customer.

This document specifies design and performance criteria arising out of the combination of a reciprocating internal combustion (RIC) engine and an alternating current (a.c.) generator when operating as a unit. This unit can run paralleling or not to the grid. It applies to a.c. generating sets driven by RIC engines for land and marine use, excluding generating sets used on aircraft or to propel land vehicles and locomotives. For some specific applications (e.g. essential hospital supplies and high-rise buildings), supplementary requirements can be necessary. The provisions of this document are a basis for establishing any supplementary requirements. For generating sets driven by other reciprocating-type prime movers (e.g. steam engines), the provisions of this document can be used as a basis for establishing these requirements.
