Tender invited for Development of Train Collision Avoidance System

ISO 9001: 2008 Effective from 18.06.2012 RDSO/SPN/196/2012 Version 3.1.1
Document Title : Specification of Train Collision Avoidance System
design / configuration and shall be approved by RDSO (the various tests
parameter for card level test, system level functional test, diagnostic test and
performance test shall be specified for inclusion in the specification).
15.3 Verification & Validation of the software and hardware shall be done by
independent assessor as per Safety Integrity Level – 4 (SIL-4) of CENELEC
standards or equivalent. Further a comprehensive report from the V&V
consultant, covering full terms of reference should be submitted to RDSO for
final assessment.
16. Tests and Verification
16.1 The test procedure shall be based on the system design. The methodologies to
be adopted for various tests shall be decided taking into account the system
design/ configuration and shall be approved by the RDSO.
16.2 The following sequence of tests shall be conducted:
• Type tests;
• Acceptance tests;
• Routine Tests;
• System acceptance tests;
• Integration Tests;
16.3 Type Tests
16.3.1 Following tests shall constitute type tests:
a) Visual inspection.
b) Insulation Resistance tests
c) Applied high voltage tests
d) Card level/ module level check
e) Card-level functional tests one card of each type.
f) System level functional tests/ performance tests
g) Environmental / climatic tests.
h) Vibration tests, abrasive environment tests.
i) System Diagnostics test.
j) Any other tests as considered necessary by the purchaser.
k) Integration Tests: Integration tests to integrate the various sub-systems of
the TCAS and demonstrate correct operation of all internal and external
interfaces.
16.3.2 Only one each equipment shall be tested for this purpose. The equipment
shall successfully pass all the type tests for proving conformity with this
specification. If the equipment fails in any of the type tests, the purchaser or
his nominee at his discretion may call for another equipment/ card(s) of the
same type and subject it to all tests or to the test(s) in which failure occurred.
No failure shall be permitted in the repeat test(s).
16.4 Acceptance Tests
Following shall comprise acceptance tests:
a) Visual inspection.
b) Insulation Resistance tests
c) Applied high voltage tests
d) Card level/ module level check.
e) Card-level functional test on all the cards.
f) System level functional tests/ performance tests.
g) System Diagnostics test.
16.5 Routine Tests
Following shall comprise the routine tests and shall be conducted by
manufacturer on each equipment and the test results will be submitted to the
inspection authority before inspection. The validation report of application
software in proper format shall also be submitted to the inspection authority in
advance.
