1. What is accreditation and what does it mean?
Accreditation involves assessment of the complete quality system of the laboratory to perform the task in an internationally agreed manner. This assessment is carried out as per Indian and international standards. Accreditation means a reputed certifying body like National accreditation body for testing laboratories (NABL), Association of Short Circuit Testing Authorities, ISO etc.. regularly assess the competence of the laboratory to perform as per internationally laid down procedures. Accreditation guarantees that all aspects of tests are impartial and based on nationally and internationally recognized standards.
CPRI is an autonomous society under Ministry of Power, Govt. of India. It is not an Institute either set up by manufacturers or utilities. Hence CPRI is an independent third party organization with high reputation as an absolutely impartial and independent institute and has been offering its services to the Power Sector for the last 61 years.

4. How can I tell if a test report is an accredited report?
Any Test Report or Certificate contains the logo of the accreditation body. This has to be checked for ascertaining the accreditation of the report. For example all the tests conducted by CPRI as per ISO/IEC 17025 carry NABL Logo in the Test Report. Also test reports /Certificates issued by INTERTEK ASTA, UL and CSA carry their respective Logos which aids in the confidence building of the Buyer of Equipment / component.
Also it is better for the Customer to check the accreditation Certificates thoroughly before ascertaining the accreditation of a Laboratory.
Accreditation guarantees that all aspects of tests are impartial and based on nationally and internationally recognized standards. An accredited report is bound to be accepted by the purchaser. An accredited report is a legally valid document.
6. Why is it important to perform measurements traceable to international standards?
The integrity of measurements done during testing is very vital since this determines the suitability of a product for any application. A reputed laboratory ensures that all the test equipment used for testing are regularly calibrated and the calibration certificates are traceable to international standards.
7. Why should I perform tests in an accredited laboratory?
The Test reports and Certificates issued by any laboratory has to be accepted by the user or purchasing authority of any product. The purchase authority always prefers a Test report or Certificate issued by and accredited Laboratory since they are authentic and traceable to any international standards. These are also legally accepted as authentic.
8. Why should I choose a Type tested product?
Type Test Certificates are special documents that are issued only if a component has been successfully tested in accordance with the relevant internationally accepted standard. For utilities or industries who buy the products “Type Test Reports/Certificates” are important documents to ensure proper operation and technical excellence of the component purchased from the vendor.
A Type Test Certificate is issued only if a component has passed all the relevant tests and meets all technical requirements. With a Type test Report/Certificate you can be sure of buying a component of good quality.
These certificates are increasingly required by electrical contractors, project specifiers and purchasers as ‘proof-positive’ that a product is tested, assured and safe. Having evidence of Certified testing enables them to confidently supply their clients with goods; minimising any chances of product liability and meeting their regulatory obligations to provide safe products.
It also goes without saying that the reputation and international standing of a laboratory is very important to the buyer of equipment. A reputed laboratory is one which exposes its facilities to the scrutiny of all national and international certification bodies to prove its worth. International standing depends on the no. of years of existence of a laboratory to signify its pioneering status, the laboratories contribution to the formulation of standards and test methods and finally its association with the prestigious international forums.
9. What is Short Circuit Testing Liaison (STL)?
CPRI is a Member of prestigious SHORT CIRCUIT TESTING Liaison (STL) panel, a premier body for hormoized application of IEC recommendations to the type testing of electrical equipment and uniform presentation of test results.
Utilities of many countries prefer test reports/certificates issued by an STL member laboratory and many Utilities seek Independent Third Party Type Test Witness by a STL Member Laboratory.
The Short-Circuit Testing Liaison (STL) is an Agreement Group of International Certification Bodies concerning the type testing of high voltage electrical power equipment. INTERTEK ASTA is a signatory to this Agreement, and thereby commits to prepare and recognise certificates to a number of IEC and other Standards following common interpretations of the Standards and the Procedures agreed by the Members of the STL. CPRI is a full member of STL and hence type test reports issued by CPRI meets the norms of STLA uniformly followed by all its members like KEMA, CESI etc.
