If there are changes in the components or in the design/type already type tested
and the design/type offered against this specification, the purchaser reserves the
right to demand repetition of tests without any extra cost before commencement
of supply.
1.4
The cells used for acceptance and type tests etc shall not be supplied to
purchaser.

Special Tests
2.1
Seismic qualification
The battery system shall be designed to meet the specified seismic requirements and
same shall be demonstrated by qualifying the battery by following :Qualification by testing two cells (with all accessories) along with dummy cells
accommodated in single battery rack on shake table as per IEEE-344 & procedure
to be submitted by vendor in a format provided by NPCIL and subsequently
approval of NPCIL. The applicable floor response spectra for the three principle
directions (horizontal and vertical) will be forwarded to the successful bidder.
If the TENDERER has already carried out tests on similar batteries with racks, and
accessories, to meet the specified response spectra or for a more severe condition,
the type test certificates for the same should be furnished for review and acceptance
by the PURCHASER. Tests must have been conducted within five years from the
date of opening of bids.
If the equipment fails to pass the seismic test due to deficiencies in design or
manufacture or malfunctioning of test set up, the CONTRACTOR shall bear such
testing charges payable to test facility.
Safe transportation of the equipment to and from the Supplier's works to the testing
laboratory, engineering and supply of materials required (for making base plates,
base frames etc.) for mounting the equipment on shake table and required manpower are to be provided by the CONTRACTOR. The CONTRACTOR shall also
arrange for various testing and measuring instruments (such as battery load bank,
fast Analogue recorder, megger, DC power supply rectifiers, storage oscilloscope
etc.) required for these tests.
In consultation with the PURCHASER and the testing agency, the
CONTRACTOR shall prepare a detailed testing procedure including the list of
parameters to be monitored during the testing as well as the tests to be carried
