FOREWORD To assess assess and improve improve the quality of electric electrical al products products and materials materials,, testing testing as per the nationa nationall and international international specifications is essential. The testing laboratories used for this purpose have to be accredited in accord accordan ance ce with with ISO/ ISO/ IEC IEC 1702 17025 5 and and follo follow w the the Electr Electrica icall specif specific ic criter criteria ia to ensur ensure e the the accur accuracy acy and and correctness of the testing methods adapted and the results obtained. The speci specific fic criter criteria ia deals deals with with the the tech technic nical al issue issues s and and serve serve the purpo purpose se of givin giving g all the neces necessar sary y information and guidelines guidelines for the preparation of an application for NABL accreditation by the laboratories and conducting assessment of the laboratories by the assessors. The revision of this specific criteria for Electrical Testing Laboratories has now been completed. A Technical Committee was setup to deliberate on various issues and has taken into account the experience gathered in the process of accrediting Electrical Testing Laboratories. I feel, this document will help the laboratories as well as the technical assessors towards achieving higher levels of excellence and hope the laboratories will ensure the Good Professional Practice in accordance with the guidelines mentioned in this document.

SCOPE OF ACCREDITATION In the field field of Elect Electric rical al Testi Testing ng the tests tests have have been been classi classifie fied d into into Produ Product ct wise wise grouping e.g. Circuit breaker, Isolator, MCB etc. from ’Switchgear equipment’ group. However certain specialized specialized tests, which are performed on a wide range of equipment, have been grouped Test Facility wise e.g. High voltage, EMI/ EMC testing etc. The laboratories can indicate their scope of accreditation either product-wise or test facility-wise depending upon their requirement (please refer Annexure I). For the Product wise classification, there are two tables in each group. Table 1 gives the products, alongwith reference to national standard (IS) and international stand standard ard (IEC). (IEC). In the absen absence ce of IS/ IEC stand standard ards, s, othe otherr intern internati ation onal al standards such as ASTM, ANSI, BS, VDE etc. have been referred. Wherever the year of the standard is mentioned the laboratory shall ensure to specify the latest amendments/ amendments/ revisions based on testing facilities. Table 2 gives the list of tests for the products listed in

Table 1.

In the Test Facility wise classification, there is only one table – Table 3. It gives the list of tests which are performed on a wide range of equipment. These have been grouped Test Facility wise e.g. High voltage, EMI/ EMC testing etc. When laboratory prepares an application for accreditation, the laboratory may refer Table 2/ Table 3 for tests and select products from Table 1 and give the range and accuracy of the test performed. The contents of the tables given in the document may not be exhaustive. The laboratory is free to add tests/ products and standards not listed in the tables. The final scope of accreditation applied for, shall be prepared in the format as given in Annexure II. The electrical instruments and the basic materials used in various electrical products/ applications, subjected to test(s) falling in more than one field, eg. transformer oil (electrical & chemical), energy meters (electrical & electronics), lamps and lumi lumina nari ries es (ele (elect ctri rica call & phot photom omet etry ry), ), dome domest stic ic appl applia ianc nces es (ele (elect ctri rica call

&

mechanical), switches and wiring accessories (electrical & mechanical) etc. are to be covered under under electric electrical al field. field. These These shall shall be subjected subjected to test(s) test(s) as specified in the relevant test standard for verifying their required properties and the relevant NABL Specific Criteria shall be followed. However the test(s) under electrical field and the other field(s) shall be clearly identified in the scope of accreditation.


6.

GRANT OF ACCREDITATION Accre Accredit ditat ation ion is norma normally lly grante granted d for for the test test facil faciliti ities es for for which which the the labora laborator tory y is properly equipped and has demonstrated its capability. The extent of a laboratory’s scope of accreditation will therefore vary with the range of work performed, the scope and and compl complex exity ity of the tests tests invol involved ved,, the compe compete tence nce of labora laborator tory y staff staff and and the capability of equipment available in the laboratory. The accreditation is accorded to a laboratory for the entire test facilities or to a part of facilities. Accreditation does not constitute a blanket approval for all activities of the laboratory. The groups of test are an arbitrary arbitrary subdivi subdivision sion of the potential potential range of activitie activities s involved in electrical testing on the basis of the type of measurements being made, the scientific disciplines involved and the techniques employed. It is therefore possible for a particular test or technique to be included under several groups of test. These groups and and subg subgrou roups ps do not not howe however ver,, const constitu itute te any any restri restricti ction on on the work work which which a laboratory can perform but provide a convenient means of expressing an accredited laboratory’s laboratory’s capabilities. capabilities. When the facility is accredited for testing of one product and it is required to test another product where the same facility can be used, the laboratory can perform the test and issue test report. However this test will need to be evaluated by NABL during subsequent surveillance so that the scope can be appropriately amended.
