The scope of the present document is to present a methodology for specification and testing of RESTful APIs,
i.e. telecommunication interfaces based on the Representational State Transfer paradigm, suitable for application in the
standardization context.
In particular, the present guide is meant to serve ETSI membership and groups in the effort to unify and consolidate the
approaches and practices in current and future standardization activities at ETSI and its Partnership Projects.
The Guide collects the best practices from standardization, industry and research in order to provide a modern and
future-proofed approach to the subject.
The intended audience is primarily standardization groups at ETSI, but the guide may also serve as reference for users
and vendors in industry, with a special focus in Open Source communities.
The Guide recommendations on conventions, methodologies, design-patterns and architectural choices to be used in
standardization of RESTful APIs, specification and execution of standardized conformance and interoperability test
suites.

This document specifies basic requirements for the installation of media for communication networks within and between the automation islands, of industrial sites. This standard covers balanced and optical fibre cabling. It also covers the cabling infrastructure for wireless media, but not the wireless media itself. Additional media are covered in the IEC 61784-5 series. This document is a companion standard to the communication networks of the industrial automation islands and especially to the communication networks specified in the IEC 61158 series and the IEC 61784 series. In addition, this document covers the connection between the generic telecommunications cabling specified in ISO/IEC 11801-3 and the specific communication cabling of an automation island, where an automation outlet (AO) replaces the telecommunication outlet (TO) of ISO/IEC 11801-3. NOTE If the interface used at the AO does not conform to that specified for the TO of ISO/IEC 11801-3, the cabling no longer conforms to ISO/IEC 11801-3 although certain features, including performance, of generic cabling may be retained. This document provides guidelines that cope with the critical aspects of the industrial automation area (safety, security and environmental aspects such as mechanical, liquid, particulate, climatic, chemicals and electromagnetic interference). This document does not recognise implementations of power distribution with or through Ethernet balanced cabling systems that are not specified in IEEE 802.3af and in IEEE 802.3at. This document deals with the roles of planner, installer, verifier, and acceptance test personnel, administration and maintenance personnel and specifies the relevant responsibilities and/or gives guidance.

This document specifies procedures for measuring and reporting the noise emission of information
technology and telecommunications equipment.
NOTE 1 This document is considered part of a noise test code (see 3.1.2) for this type of equipment and is
based on basic noise emission standards (see 3.1.1) ISO 3741, ISO 3744, ISO 3745, ISO 9295 and ISO 11201.
The basic emission quantity is the A-weighted sound power level, which can be used for comparing
equipment of the same type but from different manufacturers, or for comparing different equipment.
Three basic noise emission standards for determination of the sound power levels are specified in this
document in order to avoid undue restriction on existing facilities and experience. ISO 3741 specifies
comparison measurements in a reverberation test room; ISO 3744 and ISO 3745 specify measurements
in an essentially free field over a reflecting plane. Any of these three basic noise emission standards
can be selected and used exclusively in accordance with this document when determining sound power
levels of a machine.
The A-weighted sound power level is supplemented by the A-weighted emission sound pressure level
determined at the operator position or the bystander positions, based on basic noise emission standard
ISO 11201. This sound pressure level is not a level of noise immission at a work station (see 3.2.12), but
it can assist in identifying any potential problems that could cause annoyance, activity interference or
hearing damage to operators and bystanders.
Methods for determination of whether the noise emission includes prominent discrete tones are
specified in Annex D.
This document is suitable for type tests and provides methods for manufacturers and testing
laboratories to obtain comparable results.
The methods specified in this document allow the determination of noise emission levels for a functional
unit (see 3.1.4) tested individually.
The procedures apply to equipment which emits broad-band noise, narrow-band noise and noise which
contains discrete-frequency components, or impulsive noise.
The sound power and emission sound pressure levels obtained can serve noise emission declaration
and comparison purposes (see ISO 9296[3]).
NOTE 2 The sound power levels and emission sound pressure levels obtained are not intended to be considered
as installation noise immission levels; however, they can be used for installation planning (see ECMA TR/27[11]).
If sound power levels obtained are determined for a number of functional units of the same production
series, they can be used to determine a statistical value for that production series (see ISO 9296[3]).
