NOTE 1: (Air temperature, low).
The equipment under test shall remain operational throughout this test (without any damage or deterioration of performance, according to product
specification). If a cold start up test is performed, the characteristic severity should be used as a cold start up 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).
The equipment under test shall remain operational throughout this test (without any damage or deterioration of performance, according to product
specification). If two test temperatures are given, the lower test temperature applies if the equipment is protected against solar and heat radiation or the
equipment is ventilated (natural or forced). The higher test temperature includes the heating effects of solar and/or heat radiation. If a high temperature start
up test is performed, the characteristic severity should be used as a high start up 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).
The change of temperature test is normally used to check design tolerance. IEC 60068-2-14 [7] Test Nb shall be used. For change of temperature of
0,5 °C/min, the cooling gradient may be reduced to 0,2 °C/min where test chamber restrictions preclude a gradient of 0,5 °C/min.
NOTE 4: (Relative humidity, low).
There is no IEC 60068-2 series test method for this parameter.
NOTE 5: (Humidity, relative, high).
IEC 60068-2-78 [8] Test Cab shall be used with test values not higher than climatogram limits for this class.
NOTE 6: (Condensation).
IEC 60068-2-30 [9] Test Db shall be used with test values not higher than climatogram limits for this class.
NOTE 7: (Humidity, absolute, high).
This effect is considered to be partly included in the damp heat test IEC 60068-2-78 [8] Test Cab.
NOTE 8: (Air pressure, low and high).
No test is recommended for normal applications, because the effect of air pressure is evaluated at the component level.

NOTE 9: (Water, rain).
The effect of wind driven rain outside to the equipment in the weatherprotected or partly weatherprotected locations is included in IEC 60068-2-30 [9] Test
Db. No test is recommended.
NOTE 10: (Radiation, solar).
The higher test temperature as described in note 2 includes the heating effect of solar radiation. Photochemical tests can be made separately for
components and materials.
NOTE 11: (Radiation, heat).
The higher test temperature as described in note 2 includes the heating effect.
NOTE 12: (Chemically active substances).
The characteristic severities are given as mean/maximum values. These severities should be considered when designing the equipment and when
choosing components and materials. No test is recommended in the present document.
NOTE 13: (Mechanically active substances).
The characteristic severities are much lower than lowest test severity in IEC 60068-2-68 [14] Test L and therefore no test is recommended. This condition
should be considered when designing the equipment and when choosing components and materials.

The characteristic severities are much lower than lowest test severity in IEC 60068-2-68 [14] Test L and therefore no test is recommended. This
condition should be considered when designing the equipment and when choosing components and materials.
NOTE 13: (Flora, fauna).
The characteristic severity should be considered when choosing components and materials.

NOTE 1: (Air temperature, low).
The equipment under test shall remain operational throughout this test (without any damage or deterioration of performance, according to product
specification). If a cold start up test is performed, the characteristic severity should be used as a cold start up 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).
The equipment under test shall remain operational throughout this test (without any damage or deterioration of performance, according to product
specification). If two test temperatures are given, the lower test temperature applies if the equipment is protected against solar and heat radiation or the
equipment is ventilated (natural or forced). The higher test temperature includes the heating effects of solar and/or heat radiation. If a high temperature start
up test is performed, the characteristic severity should be used as a high start up 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).
The change of temperature test is normally used to check design tolerance. IEC 60068-2-14 [7] Test Nb shall be used. For change of temperature of
0,5 °C/min, the cooling gradient may be reduced to 0,2 °C/min where test chamber restrictions preclude a gradient of 0,5 °C/min.
NOTE 4: (Relative humidity, low).
There is no IEC 60068-2 series test method for this parameter.
NOTE 5: (Humidity, relative, high).
IEC 60068-2-78 [8] Test Cab shall be used with test values not higher than climatogram limits for this class.
NOTE 6: (Condensation).
IEC 60068-2-30 [9] Test Db shall be used with test values not higher than climatogram limits for this class.
NOTE 7: (Humidity, absolute, high).
This effect is considered to be partly included in the damp heat test IEC 60068-2-78 [8] Test Cab.
NOTE 8: (Air pressure, low and high).
No test is recommended for normal applications, because the effect of air pressure is evaluated at the component level.

NOTE 9: (Water, rain).
The effect of wind driven rain outside to the equipment in the weatherprotected or partly weatherprotected locations is included in IEC 60068-2-30 [9] Test
Db. No test is recommended.
NOTE 10: (Radiation, solar).
The higher test temperature as described in note 2 includes the heating effect of solar radiation. Photochemical tests can be made separately for
components and materials.
NOTE 11: (Radiation, heat).
The higher test temperature as described in note 2 includes the heating effect.
NOTE 12: (Chemically active substances).
The characteristic severities are given as mean/maximum values. These severities should be considered when designing the equipment and when
choosing components and materials. No test is recommended in the present document.
NOTE 13: (Mechanically active substances).
The characteristic severities are much lower than lowest test severity in IEC 60068-2-68 [14] Test L and therefore no test is recommended. This condition
should be considered when designing the equipment and when choosing components and materials.

IEC 60068-2-30 [9] Test Db shall be used with test values not higher than climatogram limits for this class.
NOTE 7: (Humidity, absolute, high).
This effect is considered to be partly included in the damp heat test IEC 60068-2-78 [8] Test Cab.
NOTE 8: (Air pressure, low and high).
No test is recommended for normal applications, because the effect of air pressure is evaluated at the component level.
NOTE 9: (Radiation, solar).
The higher test temperature as described in note 2 includes the heating effect of solar radiation. Photochemical tests can be made separately for
components and materials.
NOTE 10: (Radiation, heat).
The higher test temperature as described in note 2 includes the heating effect.
NOTE 11: (Chemically active substances).
The characteristic severities are given as mean/maximum values. These severities should be considered when designing the equipment and when
choosing components and materials. No test is recommended in the present document.
NOTE 12: (Mechanically active substances).
The characteristic severities are much lower than lowest test severity in IEC 60068-2-68 [14] Test L and therefore no test is recommended. This
condition should be considered when designing the equipment and when choosing components and materials.
NOTE 13: (Flora, fauna).
The characteristic severity should be considered when choosing components and materials.
