SIST EN 300 019-2-3 V2.1.2:2006 is the Slovenian adoption of ETSI EN 300 019-2-3 V2.1.2, a European Standard in the telecommunications series. It specifies environmental test severities and test methods for telecommunications equipment used in stationary, weatherprotected locations. In practice, it tells you how to verify that equipment can withstand the climatic and mechanical conditions linked to the environmental class you select.

What does SIST EN 300 019-2-3 V2.1.2:2006 specify?

SIST EN 300 019-2-3 V2.1.2:2006 specifies the environmental tests used to verify the required resistibility of telecommunications equipment for stationary use at weatherprotected locations. The document ties those tests to the environmental conditions defined in ETS 300 019-1-3 and organizes them by environmental class.

Clause 3 gives the environmental test specifications for the classes used at these locations. Clause 4 adds the earthquake test specification, and Clause 5 explains the notes that qualify the tables.

Annex	What it covers
Annex A	Alternative climatic test method for class 3.1
Annex B	Alternative climatic test method for class 3.2
Annex C	Alternative climatic test method for class 3.3
Annex D	Alternative climatic test method for class 3.4
Annex E	Alternative climatic test method for class 3.5

What are the key requirements of SIST EN 300 019-2-3 V2.1.2:2006?

SIST EN 300 019-2-3 V2.1.2:2006 requires the test program to match the relevant environmental class and the intended operating location. The document is written as a verification standard, so the product specification has to state what performance is expected before, during, and after each test.

Equipment state and test setup

The equipment under test is assumed to remain in its operational state throughout the described tests unless the product specification says otherwise. Input and load conditions are chosen to fully exercise the equipment, and heat dissipation is maximized except in the steady-state low-temperature case, where it is minimized.

This matters because the test should reflect real use, not a lightly loaded bench setup. It helps reveal failures that only appear when the equipment is working normally.

Climatic classes and their test tables

Clause 3 covers five location types: T 3.1 temperature-controlled locations, T 3.1 E exceptional operating conditions, T 3.2 partly temperature-controlled locations, T 3.3 not temperature-controlled locations, T 3.4 sites with heat-trap, and T 3.5 sheltered locations.

Each class has climatic tables and mechanical tables. The climatic tables cover low and high air temperature, temperature change, humidity, condensation, air pressure, air speed, rain or water exposure, icing and frosting, solar radiation, heat, chemically active substances, mechanically active substances, flora, and fauna.

Mechanical stress requirements

The mechanical tables cover sinusoidal vibration, random vibration, shocks, and, for some classes, bumps. The notes state that equipment should be mounted in the in-use position and that its function should be monitored during vibration and shock tests.

For classes 3.4 and 3.5, the standard gives two mechanical severity sets, 3M3 and 3M5. Note 19 says 3M3 may be used where the mechanical conditions are equivalent to partly- and not-temperature-controlled locations, or where high mechanical stresses are rare; otherwise 3M5 should be used. That choice affects how severe the mechanical qualification has to be.

Alternative climatic methods

Annexes A to E provide alternative climatic test methods for classes 3.1 to 3.5. These annexes use a climatogram sequence, with defined points, rates of change, pre-conditioning, and functional checks.

This is useful when a single sequence test is preferred over separate temperature and humidity tests. It also makes the functional checks explicit, so the test specification can say exactly which functions to verify at each point.

Earthquake testing

Clause 4 applies earthquake testing when the customer specifies earthquake conditions. It starts with a vibration response investigation to find the lowest resonant frequency of the mounted specimen, using either sine sweep or random testing.

If earthquake testing is needed, the document then uses a time-history method based on a required response spectrum. The mounting configuration has to represent the worst case in terms of weight, stiffness, connections, piping, and cables.

Pass/fail control

Clause 5 says the product specification must define when the equipment is operational during the test and what pass/fail criteria apply. The notes also explain when humidity control can be relaxed at low temperature, when cold start or high-temperature start tests can be used, and when separate component-level testing is more appropriate for some effects.

What terms does SIST EN 300 019-2-3 V2.1.2:2006 define?

• Operational state - The equipment is powered and functioning during the test, unless the product specification allows a different condition.
• Climatogram - The sequence of temperature and humidity points used in the alternative climatic test methods in Annexes A to E.
• Required Response Spectrum (RRS) - The earthquake spectrum used to define the time-history test in Clause 4.
• Zero Period Acceleration (ZPA) - The acceleration level used together with the RRS in the earthquake test.
• Acceleration Spectral Density (ASD) - The random vibration measure used in the IEC 60068-2-64 based vibration tests.
• Class 3M3 - A less severe mechanical environment class that may be used in selected locations with rare high mechanical stress.
• Class 3M5 - A more severe mechanical environment class used where stronger mechanical stresses are expected.

Who uses SIST EN 300 019-2-3 V2.1.2:2006?

The standard is used by equipment designers, environmental test laboratories, reliability engineers, and quality managers working on telecommunications equipment. It is also used when writing product specifications, selecting the right environmental class for a site, and planning qualification or verification tests.

Buyers and procurement teams may use it to state the required environmental robustness for stationary installations at weatherprotected locations. It is also relevant to customers who need earthquake conditions added to the test program.

What changed in SIST EN 300 019-2-3 V2.1.2:2006 from the previous edition?

This version replaces ETSI EN 300 019-2-3 V2.1.1, April 1999.

Which standards are used with SIST EN 300 019-2-3 V2.1.2:2006?

SIST EN 300 019-2-3 V2.1.2:2006 refers to several companion standards:

• ETS 300 019-1-3 - gives the environmental conditions for stationary use at weatherprotected locations.
• ETS 300 019-2-0 - provides the general overview of Part 2 of the series.
• IEC 60068-2 - supplies the individual environmental test methods used in the tables, such as cold, dry heat, change of temperature, damp heat, vibration, shock, bump, and earthquake time-history.
• IEC 60721-3-3 - supports the classification of environmental conditions and the mechanical classes referenced in the notes.

What does the SIST EN 300 019-2-3 V2.1.2:2006 document contain?

The document contains tables for climatic and mechanical test severities for classes T 3.1 to T 3.5, plus an earthquake test table and a required response spectrum figure. It also includes notes that explain when to use alternative methods, when to monitor equipment function, and how to interpret the test conditions.

Annexes A to E each give a sequence-based climatic method, including the test chamber requirements, pre-conditioning, scanning sequence, and functional verification points. Clause 4 gives the earthquake setup, and the figures show the climatograms and the response spectrum used for that test.

4 Earthquake test specification
If earthquake conditions are specified by the customer, the earthquake test requirements stated below shall be applied.
The test specification is applicable to classes 3.1 to 3.5.
4.1 Vibration response investigation
A preliminary vibration response investigation shall be carried out to determine the lowest resonant frequency of the mounted
test specimen.
The vibration response investigation can be carried out by means of sine sweep testing or random testing.
When using the sine sweep testing, the vibration response investigation shall be carried out as specified in IEC 60068-2-6 [2]
(test Fc), with the following parameter severities:
Frequency range: 1 Hz to 35 Hz
Vibration amplitude: 2 m/s
Sweep rate:£ 1 octave/min
NOTE 1: The vibration amplitude may be reduced to 1 m/s or less in case of sharp resonances.
If a random test is used this shall be performed in accordance with the requirements of IEC 60068-2-64 [2], using the following
severities:
Frequency range: 1 Hz to 20 Hz 20 Hz to 35 Hz
2 3
ASD: 0,5 m /s -3 dB/octave
Duration: 3 minutes
2 3
NOTE 2: The Acceleration Spectral Density (ASD) value may be reduced to 0,3 m /s or less in case of sharp resonances.
The time-history stated in table 12 can be omitted if, after the vibration response investigation, the equipment does not exhibit
any resonance below 5 Hz and has passed the sinusoidal vibration test reported in table 9 (class 3.4) or in table 11 (class 3.5)
for class 3M5. This test is sufficient to prove compliance with earthquake conditions given in ETS 300 019-1-3 [1].
ETSI
24 ETSI EN 300 019-2-3 V2.1.2 (1999-09)
4.2 Test conditioning
See table 12.
The extent to which the equipment under test has to function during tests or merely to survive conditions of test shall be stated in the product specification.

5 Notes to tables
5.1 General note
The present document applies to the use of stationary equipment at weather protected locations covered by the environmental
conditions stated in ETS 300 019-1-3 [1].
The relevant test specification should specify when, during the environmental test programme, the equipment is in it's
operational state, and which performance requirements should be measured before, during and after the test, together with the
appropriate pass/fail criteria.
5.2 Notes to tables 1 to 12
NOTE 1: (Air temperature, low)
The characteristic severity can be used as a cold start up temperature, but it may be modified by the product specification. The
equipment under test shall remain operational throughout this test, except for the cold start up test which shall commence once
low temperature stability is achieved.
