Recommended list of various raw materials is given in Annexure II.5.3 PROCESS CONTROL – The frequency of inspection and parameters shall beaccording to the approved plant quality audit programme. The areas of manufacturinggiven in Annex III shall be covered in this programme. During each stage, the givenparameters and equipment set up shall be controlled, audited and recorded.5.4 TYPE APPROVAL/TYPE TEST: For type approval/type test, theprocedure stipulated under clause 6 and Table 19 of IS 15636 shall be followed for eachfamily of Tyres before permission is granted for covering the tyres under BISCertification Marks Scheme. For changes in the technical specification of alreadyapproved tyres or for extension of type approval, the procedure as specified in cl. 6.2.3 to6.2.5 of IS 15636 shall be followed .5.5 CONFORMITY OF PRODUCTION TEST/ACCEPTANCE TEST: Duringoperation of licence, the procedure stipulated under cl. 7.1 to 7.4 and Table 20 of IS15636 shall be followed for conformity of production test/acceptance test.6.0 REJECTIONS – A separate record shall be maintained giving informationrelating to the rejection of the production not conforming to the requirements of thespecification and the method of its disposal. Such material shall in no circumstances bestored together with that conforming to the specification.7.0 SAMPLES – The licensee shall supply, free of charge, the samples required inaccordance with the Bureau of Indian Standards (Certification) Regulations, 1988, assubsequently amended, from the factory or godowns. The Bureau shall pay for thesamples taken by it from the open market.8.0 REPLACEMENT – Whenever a complaint is received soon after the goods withStandard Marks have been purchased and used, and if there is adequate evidence that thegoods have not been misused, defective goods or their components are replaced or repairedfree of cost by the licensee in case the complaint is proved to be genuine and the warrantyperiod (where applicable) has not expired. The final authority to judge the conformityof the product to the Indian Standard shall be with the Bureau. The firm shall have owncomplaint investigation system as per IS/ISO 10002.Page 2 of 10

Doc: STI/15636/ 2, April 20118.1 In the event of any damages caused by the goods bearing the Standard Mark, orclaim 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 productshall be of licensee and BIS shall not in any way be responsible in such cases.9.0 STOP MARKING – The marking of the product shall be stopped underintimation to the Bureau if, at any time, there is some difficulty in maintaining theconformity of their product to the specification, or the testing equipment goes out oforder. The marking may be resumed as soon as the defects are removed under intimationto Bureau.9.1 The marking of the product shall be stopped immediately if directed to do so byBureau for any reason. The marking may then be resumed only after permission by theBureau. The information regarding resumption of markings shall also be sent to theBureau.10.0 PRODUCTION DATA – The licensee shall send to BIS as per the enclosedproforma-1 to be authenticated by a Chartered Accountant a statement of quantityproduced marked and exported by him and the trade value thereof at the end of eachoperative year of the licence.Table 1………Page 3 of 10
