equipment required to perform the test of 3rd party vendor packaged equipment ICSS interfaces at the
vendor's facilities shall be supplied by the ICSS vendor.
Inspection shall include a physical check and functional check for compliance with the specifications. It
also includes continuity check and loop testing of electrical and electronic wiring, the nameplate

to witness all functional tests. Waiver of inspection does not relieve the Vendor of his responsibility for
proper test, instrument installation and panel construction.
Factory Acceptance Testing (FAT):

Vendor shall notify Contractor at least ten (10) working days in advance of commencement of
testing and final inspection(s) to allow Contractor designated personnel and Client designated
personnel to witness said testing and final inspection.

Before the witness tests commence, the vendor shall have performed a complete system
Vendor functional test in accordance with the vendor's standard procedure. This internal test
reports shall be furnished to Client / Contractor before start of FAT

Vendor will provide a FAT Test Procedure, indicating the steps of the test.

The Vendor shall provide all necessary test equipment and simulation facilities required for the
witnessed tests and supply manpower in order to simulate analog and digital input signals and
display/demonstrate the resulting analog or digital output.

The vendor shall develop a redundancy switch over test procedure which clearly defines the
method of testing the switch over of redundant components and the expected results. The
procedure shall be part of the FAT Test Procedure document and as such shall be available for
review prior to the FAT.

Prior to delivery to the site, the mechanical package control system shall be subjected to a
thorough inspection and checkout to verify the correct operation of the PLC System and all
associated I/O hardware. The PLC System checkout shall be conducted by the System
Integrator (e.g., Local Panel Fabricator).

All FAT testing shall include all the interfaces between the packaged equipment PLC System
and the BPCS/SIS systems. Signals normally originating or received by the BPCS/SIS shall be

simulated accordingly.

Documentation of detailed test results including all AS BUILT data link mapping shall be
provided prior to shipment of equipment.

The witnessed test shall consist of a functional check of each I/O point, alarm point, digital and
regulatory control loop for proper functions and displays on the operator interface and shall
include the following tests:

The system shall not be accepted until the entire system has passed an error - free test. Once a failure
or an error has been detected by internal diagnostic system, repairs may be made.
If the test is aborted, and/ or the equipment rejected, the Vendor shall rectify the problem and advise a
date for retest. A report shall be forwarded to Client and Contractor before the retest detailing why the
equipment was rejected and what actions have been taken to rectify the problem. These repeat tests
shall be at the Vendor’s cost.
