30 April 2017 after which the old Standard shall stand withdrawn.

3. IS 13340 (Part 2):2012/IEC 60831-2:1995 supersedes IS 13341:1992 (Requirements and

methods for Ageing Test, Self-Healing Test and Destruction Test on Shunt Capacitors of the

Self-Healing Types for AC Power Systems having a Rated Voltage up to and including

1000 V).

4. All BOs may inform the Applicants and Licensees under their jurisdiction about the revised

Standards.

5. The significant changes in the revised IS 13340 (Part 1):2012/IEC 60831-1:2002 listed at

Annexure 1 is given for the purpose of general guidance. BOs shall ensure that the product

conforms to all the requirements, as applicable, as per the revised Standard.

6. Consequent upon the issuance of the revised Standard, existing STI has been revised as

7. The guidelines for implementation of the revised Standard is given below:

A. For Licensees:

(i) All Licensees shall switchover to the revised Standard by 30 April 2017. BOs shall ensure that

no Licences are under operation as per the old Standard after 30 April 2017.

(ii) Licensees shall confirm conformance to the additional/modified requirements through

In-house/Independent Test Reports or Test Certificates, as applicable. Verification of

additional requirements and facilities, if any, may be done during the next surveillance visit.

(iii) BO may issue endorsement for the revised STI after receipt of STI Acceptance and the

confirmation from the Licensee on implementation of the revised Standard. If the Licensee

fails to complete all actions by 30 April 2017 it shall be dealt with as per OMPC.

B. For Applicants:

(i) Existing Applications may be processed as per the old Standard. However, if the Applicant is

desirous of considering the Application as per the revised Standard, a declaration from the

Applicant may be obtained to that effect and the Application may be processed accordingly.

An undertaking from such Applicants shall also be obtained that if the sample fails in new

test requirements, Licence will not be granted by BIS as per the old version.

(ii) Applications which are recorded henceforth shall be processed only as per the revised

Standard.

(iii) Wherever it is required to submit Test Report along with the Application and the Sample has

been submitted in the Laboratory/Test Report has been issued by the Laboratory as on date of

issue of these guidelines, such Applications shall be accepted as per the version of the

Standard indicated in the Test Report.

(iv) For any Application which are processed as per the old Standard, Applicant shall give a

declaration that they will switch over to the revised Standard by 30 April 2017.

(v) Beyond 30 April 2017 no Licence shall be granted as per the old Standard.

15 Impulse test voltage specified as “peak value of 8 kV if the rated voltage

of the capacitor is UN ≤ 690 V or peak value of 12 kV if UN > 690 V”

instead of crest value of 15 kV.

16 Test voltage specified as 2UN for three phase Delta connection and

4UN/√3 for three phase Star connection instead of “ 2 times rated element

voltage”

18 As per IS 13340 (Part 2), Test voltage of Self-Healing test is given as 2.15

UN instead of 1.75UN as given in IS 13341.

be used for controlling the quality of the product during production as envisaged in this Scheme

[see IS 397 (various parts)].

3.2 In addition, effort should be made to gradually introduce a Quality Management System in

accordance with IS/ISO 9001.

4. STANDARD MARK

4.1 The Standard Mark, as given in Column (1) of the First Schedule of the licence shall be

applied on the rating plate of each capacitor unit, provided always that the capacitor unit to

which the Standard Mark is applied conforms to every requirement of the specification.

5. MARKING

5.1 The marking on the capacitor unit/bank shall be in accordance with Section 5 of IS 13340

(Part 1): 2012/IEC 60831-1: 2002.

6. LEVELS OF CONTROL

6.1 The tests as indicated in Table 1, and at the levels of control specified therein, shall be

carried out on the whole production of the factory covered by this scheme and appropriate

records maintained in accordance with clause 2 above and charts may be maintained as per

clause 3 above. All the production which conforms to the Indian Standard and covered by this

licence shall be marked with Standard Mark.

6.2 On the basis of the test results, decision regarding conformity or otherwise of the production

shall be made as follows:

6.2.1 Every capacitor taken for routine tests shall satisfy the requirements of the specification.

DOC: STI/13340 (Part 1)/1 December 2016

6.2.2 Every capacitor sample to which it is intended to apply the Type test shall first have

withstood satisfactorily the application of all the routine tests.

6.2.3 However, capacitor found defective in any of the routine tests may be suitably modified,

if possible, otherwise rejected. The capacitors, if rectified shall again be tested for all the routine

tests and only those capacitors shall be accepted which are found satisfactory.

6.3 In case of failure of any sample in any of the type tests, the marking shall be suspended and

necessary modification shall be made in the design. Marking shall be resumed only after the

test(s) on five samples taken from modified design are found to be satisfactory. BIS to be kept

informed of such Stoppage and Resumption of Marking.

6.4 In respect of all other clauses of the Specification and at all stages of manufacture, the

factory shall maintain appropriate control and checks to ensure that the product conforms to

various requirements of the Specification.

7. REJECTIONS

7.1 A separate record shall be maintained giving information relating to the rejection of the

production not conforming to the requirements of the Specification and the method of disposal.

Such material shall in no case be stored together with that conforming to the Specification.

8. SAMPLES

8.1 The licensee shall supply, free of charge, the samples required in accordance with the

Bureau of Indian Standards (Certification) Regulations, 1988, as amended from time to time,

from the factory or godown. BIS may draw samples from the open market, if available.

9. REPLACEMENT

9.1 Whenever a complaint is received soon after the goods with Standard Mark have been

purchased and used, and if there is adequate evidence that the goods have not been misused,

defective goods shall be replaced free of cost by the licensee in case the complaint is found to

be genuine and the warranty period (where applicable) has not expired. The final authority to

judge the conformity of the product to the Indian Standard shall be with BIS.

9.2 In the event of any damage caused by the goods bearing the Standard Mark, or any claim

being filed by the consumers against BIS Standard Mark and not “conforming to” the relevant

Indian Standard, entire liability arising out of such non-conforming product shall be of the

licensee and BIS shall not in any way be responsible in such cases.

10 STOP MARKING

10.1 The marking of the product shall be stopped under intimation to BIS if, at any time, there

is some difficulty in maintaining the conformity of their product to the Specification, or the

testing equipment goes out of order. The marking may be resumed as soon as the defects are

removed under intimation to BIS.

10.2 The marking of the product shall be stopped immediately if directed to do so by BIS for

any reason. The marking may then be resumed only after permission by BIS. The information

regarding resumption of marking shall also be sent to BIS.

DOC: STI/13340 (Part 1)/1 December 2016

11 PRODUCTION DATA
