3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 60721 series and EN 60068
series and the following apply.
3.1
product documentation
set of documents that may contain any of the following:
- the manufacturer's installation and operations literature which accompanies the product;
- the product information contained in the manufacturer's catalogue and other product
marketing material-information;
- the description, definitions, product literature and usage as presented in electronic format on the
manufacturer's (or supplier's) website on the World Wide Web/Internet
3.2
weather protected locations: controlled conditions
locations that are enclosed, and where direct weather influences are totally excluded. In addition,
temperature is controlled by heating or cooling to maintain the required conditions, especially where these
are very different from those of the open-air climate. Humidity is not controlled. Vibration and shock are
insignificant.
These locations may be in rural and some urban areas with low industrial activities and moderate traffic.
There is no particular risk of biological attack due to mould growth, animals, etc.
EXAMPLES:
- normal living or working areas, for example living rooms, and rooms for general use such as theatres,
restaurants, offices, shops, workshops for electronic assembly and products;
---------------------- Page: 7 ----------------------
SIST EN 50491-2:2011
EN 50491-2:2010 – 6 –
- telecommunication centres;
- storage rooms for valuable and sensitive products.
3.3
weather protected locations: uncontrolled conditions
locations that are enclosed, but whether direct weather influences are not completely excluded.In
addition, neither temperature nor humidity is controlled, although heating may be used to raise low
temperatures where there is a large difference between the conditions of this class and those of the open-
air-climate. Vibration is of low significance.
EXAMPLES:
- entrances and staircases of buildings, garages, cellars, and certain workshops;
- buildings in factories and industrial process plants;
- unattended equipment stations, certain telecommunication buildings, ordinary storage;
- rooms for frost-resistant products, farm buildings, etc.
4 General explanation for all tests
The variety and the diversity of the devices within the scope of this standard make it difficult to define
precise criteria for the evaluation of the immunity test results.
If, as a result of the application of the tests defined in this standard, the device becomes dangerous or
unsafe, the device shall be deemed to have failed the test.
5 Environmental conditions
5.1 General test conditions
The HBES/BACS devices shall be designed for use in one or more of the environment classes according
to the classification in the EN 60721-3 series as indicated in Table 6.1 up to Table 6.4.
All test procedures are described in the EN 60068 series.
Environmental tests shall be applied in accordance with the test method in the relevant basic standard of
the EN 60068 series. In addition the following shall apply:
- the device shall be in operation during all tests except those for storage and transportation;
- the tests shall be made in the most susceptible operating mode;
- it is not always possible to test every function of the devices, and in such cases the most critical
mode of operation shall be selected;
- the tests shall be carried out as single tests in sequence. The sequence of testing is optional;
- the description of the test, the test method and the test set-up are given in basic standards
(EN 60068-x-x) which are referred to in the following tables;
- the content of these basic standards is not repeated here. However, details of modifications and
other information needed for the practical application of the tests are given in this European
Standard.
5.2 General performance criteria
During (except for storage and transportation) and after all tests the device shall not block the
transmission media or send unintended telegrams.
A functional description and a definition of performance criteria, during or as a consequence of
environmental testing, shall be provided by the manufacturer and noted in the test report, based on the
following criteria.
