NOTE
a) The Test results relate only to the item(s) tested.b) Publication or reproduction of this report in any form other than by complete set of the
whole test report / Certificate and in the language written is not permitted without the writtenconsent of CPRI.
c) Any Corrections / erasure invalidate the test ReporUCertificate.d) NABL has Accredited this laboratory as per ISO 17025-2005 standard, vide
certificate no.T-0010 for the tests carried out.e) Any anomaly / discrepancy in the test report / Certificate should be brought to notice of CPRI
within 45 days from the date of issue.
Additional Information:This is not a certificate of rating. A certificate of rating is not issued as only limitedtests as requested by the customer were carried out.
CPRI issues following types of reports/certificates:
Test Report:The test report contains the record of the values of test parameters as obtained duringtesting, the physical condition of the sample during / after the test(s) and copy ofoscillogram(s). Test report is issued when partial tests are performed as against thecomplete test requirement for proving specific ratings.
Sealed Certificate:The sealed certificate is issued, on request and payment of the prescribed charges thereofonly when the sample of particular type and rating has satisfactorily passed all the specifiedtests in compliance with the condition stipulated in a published National/Internationalstandard.
CPRI issues the following type test certificates based generally on STL Guidelines:
I. Type test certificate of Short Circuit Performance.11. Type test certificate of Switching Performance.Ill. Type test certificate of Temperature Rise Performance.IV. Type test certificate of Dielectric Performance.V. Type test certificate of complete type test.
