IEC 60068-3-3:2019 applies primarily to electro-technical equipment but its application can be extended to other equipment and to components. In addition, if some type of analysis is always performed when making a seismic qualification, for example for the choice of the representative sample to be tested or for the extension of the seismic qualification from the tested specimen to similar specimens, the verification of the performance of an equipment by analysis or by a combination of testing and analysis can be acceptable but is outside the scope of this document, which is restricted to verification based entirely upon data from dynamic testing. This second edition cancels and replaces the first edition published in 1991. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the main aim of this revision is to connect the testing level to the seismic activity level of the zone where the equipment could be installed; - a standard shape for the required response spectrum is also given for the general seismic class for which the seismic environment is either not known or is imprecisely known; - Clauses 11 to 15 were renumbered and some adjustments were made as their content is very general and the requirements can be applied both to the general seismic class and to the specific seismic class; - the word “envelope” is replaced with “dominance” and “to envelop” with “to dominate” in order to provide a more precise meaning from a mathematical point of view.

The present document defines solutions for progressive migration of Information and Communication Technology
(ICT) sites (telecommunication and data centres) to up to 400 V Direct Current (400 VDC) distribution and direct use of
up to 400 VDC powering ICT equipment from 400 VDC sources. The present document also defines different major
use case options and migration scenarios, such as:
• migration to an up to 400 VDC of telecommunication site power solution;
• migration to an up to 400 VDC of data centre power solution;
• migration with up to 400 VDC power transfer between existing -48 V centralized sources to high power
density -48 V equipment, such as routers;
• integration of up to 400 VDC remote powering;
• combined architecture with up to 400 VDC and AC sources and distributions possibly using hybrid power
interfaces on ICT equipment.
For each of these, the present document describes many possible options and characteristics, such as:
• migration architecture with up to 400 VDC/-48 V conversion to power existing -48 V equipment using
existing -48 V room distribution;
• conditions for tripping overcurrent protection devices without -48 V batteries;
• migration architecture with up to 400 VDC/AC inverter as an alternative to the AC UPS to power existing AC
equipment;
• use of local up to 400 VDC for remote powering of ICT equipment;
• coupling up to 400 VDC systems to a local REN source or to a DC microgrid;
• possibility of conversion between battery and up to 400 VDC distribution, e.g. for long power distribution or
short-circuit current or battery technology (e.g. lithium-ion).
The present document also gives a saving assessment frame reference to define the best migration scenario and its steps
by considering energy, resource, environmental impact and cost savings based on functional aspects such as modularity,
flexibility, reliability, efficiency and distribution losses, as well as maintenance evolution when migrating from -48 V or
Alternating Current (AC) to up to 400 VDC solutions. This also includes consideration of load architecture evolution
dependent on use cases (e.g. telecommunication site, data centres).

IEC 60068-2-85:2019 demonstrates the adequacy of specimens to resist dynamic loads without unacceptable degradation of its functional and/or structural integrity when subjected to the specified vibration test requirements as defined by a time history (long time history replication). These can either be recorded in measurement exercises or generated artificially. In both cases, this method allows for generating a test tailored to very specific applications.

IEC 62056-3-1:2021 is available as IEC 62056-3-1:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 62056-3-1:2021 describes two sets of profiles: the first set of profiles allows a bidirectional communication between a client and a server. This set of profiles is made of three profiles allowing local bus data exchange with stations either energized or not. For non-energized stations, the bus supplies energy for data exchange. Three different profiles are supported:
• base profile: this three-layer profile provides remote communication services;
NOTE 1 This first profile was published in IEC 61142:1993 and became known as the Euridis standard.
• profile with DLMS: this profile allows using DLMS services as specified in IEC 61334 4 41;
NOTE 2 This second profile was published in IEC 62056-31:1999.
• profile with DLMS/COSEM: this profile allows using the DLMS/COSEM Application layer and the COSEM object model as specified in IEC 62056 5 3 and in IEC 62056 6 2 respectively.
The three profiles use the same physical layer and they are fully compatible, meaning that devices implementing any of these profiles can be operated on the same bus. The transmission medium is twisted pair using carrier signalling and it is known as the Euridis Bus.
The second set of profiles allows unidirectional communication between a given Energy Metering device and a Customer Energy Management System. This second set is made up of three profiles.
Subclause 4.2.1 to Clause 8 included specify the bidirectional communication using twisted pair signalling and Clause 9 to 9.5 the unidirectional communication using twisted pair signalling.
This second edition cancels and replaces the first edition of IEC 62056-3-1, issued in 2013, and constitutes a technical revision.
The main technical changes with regard to the previous edition are as follows:
• addition of a profile which makes use of the IEC 62056 DLMS/COSEM Application layer and COSEM object model;
• review of the data link layer which is split into two parts:
– a pure Data Link layer;
– a "Support Manager" entity managing the communication media;
• ability to negotiate the communication speed, bringing baud rate up to 9 600 bauds.
