High Pressure Leak Test (HPLT)
HPLT is an optional piping configuration. The following section describes functionality of HPLT for
systems designed with the HPLT piping configuration.
7.9.1 Definitions
HPLT -
High Pressure Leak Test. This is the term used to describe the leak test function performed at
an elevated pressure on the CGA connection between a pigtail and cylinder. The control system
utilizes a pressure transducer to monitor for pressure decay and will indicate the presence of a leak.
Standard leak test -
this is the leak test function supplied with standard cabinets. It can be configured
as either inboard or outboard. Inboard is done with a helium spray at the CGA connection and a leak
detector pulling a vacuum through the leak test port. Outboard is done with a sniffer probe sensing at
the pressurized CGA connection.
