Standards
Relevant Standards for PV Connectors:
IEC61215: General PV climate tests No connector specific tests
IEC61730: Requirements of insulation material for connectorsNo connector specific tests for electrical & long term behaviour
UL1703: General PV module tests No connector specific tests
IEC61984: General standard for connectorsNo specific long term tests
No valid standard for PV Connectors with specific long term tests.

Selection Criteria
Important points which have to be considered when choosing PVconnectors for inverters and modules: Safety, long term behaviour & compatibility A certification just for IEC61215 or just for TV safety class II does not
mean that the connector is safe and long time reliable. For this acombination of several tests is needed.
There are some very important features specially for PV connectors whichare not tested in the above mentioned tests, e.g. resistance of the contacts.The problems are as follows: Higher temperatures speed up the aging effect.
With fast aging, the contact resistance again increases.
At the end some of the contacts fail and cause interruption, arcing fire...
