Description / Abstract:
This International Standard specifies definitions and test
methods for durability and performance of heat-pipes for solar
thermal application.
This standard is applicable to all heat-pipes for use with
evacuated tubes, including glass-metal sealed evacuated tubes and
double-glass evacuated tubes, as well as with flat plate
collectors.
This standard provides test methods for determining durability
of the heat-pipe, including high temperature resistance and freeze
resistance.
This standard also provides test methods for measuring
performance of the heat-pipe, including starting temperature,
temperature uniformity and heat transfer capacity of the
heat-pipe.
This standard is only applicable to gravity heat-pipes.
