31.240 - Mechanical structures for electronic equipment

This part of IEC 62966, dedicated to aisle containment techniques for information technology
(IT) equipment typically used in data centres, describes the quantification of its air tightness, in
particular the air loss ratio that describes the content of the volumetric flow not used for cooling
the IT equipment. This ratio provides an index of efficiency, being inversely proportional to
efficiency (the lower this ratio, the higher the efficiency). This document provides methods to
measure an...view more

This part of IEC 61969 specifies a set of basic environmental requirements and tests, as well
as safety aspects for outdoor enclosures under conditions of non-weather protected locations
above ground.
The purpose of this document is to define a minimum level of environmental performance in
order to meet requirements of storage, transport and final installation. The intention is to
establish basic environmental performance criteria for outdoor enclosure compliance.

This part of IEC 61969 contains design guidelines for outdoor enclosures and is applicable over
a wide field of mechanical, electromechanical and electronic equipment and its installation
where a modular design is used.
The objectives of this document are:
– to provide an overview of specifications for enclosures focused on requirements for outdoor
applications for stationary use at non-weather protected locations, and
– to achieve product integrity under outdoor conditions and to ease pro...view more

IEC 62966-2:2020 is dedicated to aisle containment techniques for information technology (IT) equipment typically used in data centres, describes the quantification of its air tightness, in particular the air loss ratio that describes the content of the volumetric flow not used for cooling the IT equipment. This ratio provides an index of efficiency, being inversely proportional to efficiency (the lower this ratio, the higher the efficiency).
