The detailed descriptions of the environmental conditions are given in clauses 4 and 5 of ETSI EN 300 019-1-4 [1]. ETSI EN 300 019-2-0 [i.1] forms a general overview of part 2 of this multi-part deliverable. 4.1 Equipment setup and configuration The equipment shall be tested in its operational state throughout the test conditions described in the present document unless otherwise stated.

ETSI ETSI EN 300 019-2-4 V2.5.1 (2018-07)7 4.2 Performance criteria The following performance criteria shall apply in the tests defined by the present document. Performance criterion A: The equipment shall function according to the manufacturer specifications before, during and after the tests. No degradation of performance or loss of function is allowed below the performance level specified by the manufacturer when the apparatus is used as intended. If the minimum performance level is not specified by the manufacturer, then this may be deduced from the product description and documentation and what the user may reasonably expect from the apparatus if used as intended. Performance criterion B: The equipment shall function according to the manufacturer specifications before and after the tests. During the test it is not required to monitor the equipment functionality. No degradation of performance or loss of function is allowed below the performance level specified by the manufacturer when the apparatus is used as intended. If the minimum performance level is not specified by the manufacturer, then this may be deduced from the product description and documentation and what the user may reasonably expect from the apparatus if used as intended. Performance criterion C: The equipment shall function according to the manufacturer specifications before and after the tests. No degradation of performance or loss of function is allowed below the performance level specified by the manufacturer when the apparatus is used as intended. If the minimum performance level is not specified by the manufacturer, then this may be deduced from the product description and documentation and what the user may reasonably expect from the apparatus if used as intended. During the application of the test, temporary loss of function is allowed but after the test the equipment shall restore to the normal functionality without replacement of components, manual rebooting or human intervention. The equipment shall sustain the test without permanent structural or mechanical damage. Performance criterion D: This performance criterion applies to the enclosure of the equipment. No corrosion traces (e.g. rust) or deterioration of the enclosure shall occur at the end of the test. SIST EN 300 019-2-4 V2.5.1:2018

14 NOTE 1: (Air temperature, low). Two test temperatures are given, the lower test temperature shall apply if the equipment is protected against solar irradiation. The higher test temperature includes heat irradiation emitted from the equipment. The temperature cold start up test shall be performed according to the characteristic severity temperature, but it may be modified (within the class characteristic severity range) by the product specification. In this case, the cold start up test shall commence once low temperature stability is achieved. NOTE 2: (Air temperature, high). Two test temperatures are given, the lower test temperature shall apply if the equipment is protected against solar radiation or the equipment is ventilated (natural or forced). The higher test temperature includes the heating effects of solar radiation. The temperature start up test shall be performed according to the characteristic severity temperature, but it may be modified (within the class characteristic severity range) by the product specification. In this case, the high temperature start up test shall commence once high temperature stability is achieved. NOTE 3: (Air temperature, change). This test is intended for specimen with large thermal time constant. For equipment where the rapid change of temperature of the surface has a significant effect on internal components, the values of the change of temperature up to 5 °C/min can be applied. NOTE 4: (Humidity, relative high). IEC 60068-2-78 [16] Test Cab shall be used with test severities not higher than climatogram limits for this class. NOTE 5: (Condensation). IEC 60068-2-30 [9] Test Db shall be used with test severities not higher than climatogram limits for this class. NOTE 6: (Humidity, absolute, high). This effect is considered to be partly included in the damp heat test IEC 60068-2-78 [16] Test Cab. NOTE 7: (Air pressure, low and high). No test is required for normal applications, because the effect of air pressure is evaluated at the component level. NOTE 8: There is no IEC 60068-2 [i.3] series test for this parameter. NOTE 9: (Water, rain). IEC 60068-2-18 [15] Test Rb method 1.2 "Spay nozzle" has been chosen even if it does not imitate normal rain. It is a simple hand held shower test, easy to perform and can demonstrate that the specimen design is adequately toleranced to survive this condition. The cooling effect of the low temperature of the rain is included in IEC 60068-2-14 [8] Test Nb. Two durations are given, whichever is the greatest should be chosen. NOTE 10: (Water, other sources). No test is required because the effect is already included in IEC 60068-2-18 [15] Test Rb. NOTE 11: (Radiation). The heating effect of solar radiation is included in the higher test temperature in IEC 60068-2-2 [7] Test Bb as described in note 2. Photochemical tests can be performed separately for component and materials. NOTE 12: (Chemically active substances). Characteristic severities are mean/maximum values. The characteristic severities should be considered when designing the equipment and when choosing components and materials. No test is required in the present document, except for the mechanical enclosures, where the salt mist test is required to be performed. The execution of this test can be performed on the entire enclosure or subparts of the enclosure if the results are not affected. NOTE 13: (Mechanically active substances). The characteristic severities are much lower than the lowest test severity in IEC 60068-2-68 [i.2] Test L and therefore no test is required. This condition should be considered when designing the equipment and choosing components and materials.

NOTE 14: (Flora and fauna). The characteristic severities should be considered when choosing components and materials.

IEC 60068-2-18 [15] Test Rb method 1.2 "Spray nozzle" has been chosen even if it does not imitate normal rain. It is a simple hand held shower test, easy to perform and can demonstrate that the specimen design is adequately toleranced to survive this condition. The cooling effect of the low temperature of the rain is included in IEC 60068-2-14 [8] Test Nb. Two durations are given, whichever is the greatest should be chosen. NOTE 10: (Water, other sources). No test is required because the effect is already included in IEC 60068-2-18 [15] Test Rb. NOTE 11: (Radiation). The heating effect of solar radiation is included in the higher test temperature in IEC 60068-2-2 [7] Test Bb as described in note 2. Photochemical tests can be performed separately for component and materials. NOTE 12: (Chemically active substances). Characteristic severities are mean/maximum values. The characteristic severities should be considered when designing the equipment and when choosing components and materials. No test is required in the present document, except for the mechanical enclosures, where the salt mist test is required to be performed. The execution of this test can be performed on the entire enclosure or subparts of the enclosure if the results are not affected. NOTE 13: (Mechanically active substances). The characteristic severities are much lower than the lowest test severity in IEC 60068-2-68 [i.2] Test L and therefore no test is required. This condition should be considered when designing the equipment and choosing components and materials.

NOTE 14: (Flora and fauna). The characteristic severities should be considered when choosing components and materials.
