(1) Every person, who submits any model of weight or measure for approval (hereinafter in this rule referred to as, the applicant), shall deposit to the credit of the recognised laboratory, a fee determined at the rate specified by the Director from time to time, subject to the maximum prescribed under the Act.
 
(1A) 
 All the documents referred to in rule 5 shall be sent by the Director to the recognized laboratory which carries out the tests for the approval of the model, to enable the laboratory to ascertain whether such documents conform to the details of the results of the tests carried out by it for the approval of that model.] 2[\*\*\*] 1[(5)  Where the nature of weight or measure is such that due to its voluminous nature it cannot be submitted to the laboratory for testing, the recognized laboratory may undertake the testing of such model at such place as it may deem fit: Provided that, where the test is undertaken at any premises other than those of a recognized laboratory, the applicant shall pay for the duration of such test, the travelling and daily allowances of the persons deputed for such tests and such allowances shall be payable at such rates as may be admissible to such persons in accordance with the rules in force in the recognised laboratory].
 
(6) The applicant shall provide such facilities as may be required by the team of persons deputed by the recognised laboratory for the purpose of carrying out the necessary tests for the approval of the model.
 
(7) The installation, tests and removal of the model shall be done at the cost and risk of the applicant.
 
(8) The Central Government and the recognised laboratory shall not be responsible for any loss or damage that the model may sustain during the course of examination and testing.
 
(9) Where any model submitted to a recognised laboratory for approval is not removed by the applicant after the expiry of six months from the date on which a certificate of approval was granted or refused in relation to such model, such model shall become forfeited to the Central Government, and that Government shall dispose of the model in such manner as it may think fit. 3[(10) The Director may, if he is satisfied that the test for the approval of any model is likely to take more than three months and on receipt of satisfactory perliminary test reports from the laboratory, issue subject to such conditions as may be specified in the certificate, a provisional certificate to such conditions as may be specified in the certificate, a provisional certificate to enable the manufacturer, to manufacture at his own risk the weight or measure in relation to which the mdoel has been submitted for approval: Provided that manufacture, distribution or sale of such instrument shall be discontinued immediately when the provisional model approval certificate has been withdrawn by the Director: Provided further that in case the tested model does not meet the requirements of the model approval test, all instruments covered by the provisional certificate and sold in the market shall be withdrawn with immediate effect at the manufacturer's cost.]
 
### 7. Tests for the approval of model.—
(1) The tests needed for the assessment of the fitness or otherwise of a model submitted for approval shall be carried out under the normal conditions of use, whether actual or simulated, of the weight or measure and shall be made with a view to—(a) ascertaining whether such model conforms to the standards established, in relation to such model, by or under the Act 1[and the rules or to the recommendations of the International Organisation of Legal Metrology (OIML)];
 
(b) finding out the ability of such model to maintain accuracy and other metrological characteristics and qualities after it has been put to use for such minimum number of times or over such minimum period as the Director, may, by general order, specify in relation to the class of weight or measure to which the model pertains;
 
(c) determining the performance of such model under varied conditions of use;
 
(d) determining the metrological and technical characteristics of the model after taking into account the possible incidence of influence factors and their effect on metrological and technical characteristics; 2(e) determining whether the place or place of sealing on the instrument suggested by the manufacturer is sufficient to prevent their fraudulent use;
 
[(f) determining generally, the behaviour of the model, that is to say, its robustness reliability and susceptibility to fraudulent use:] Provided that, in the case of a weight or measure which is required to possess any special metrological or technical characteristics or behaviour, the assessment as to the fitness for approval or otherwise of the model of such weight or measure shall be made after carrying out such special tests as may be necessary for determining the existence or otherwise of the required metrological or technical characteristics or behaviour.
 
(2) Every model shall be tested in accordance with such test procedure as may be laid down by the Director in relation to the class of weight or measure to which such model pertains: Provided that until the test procedure is laid down by the Director in relation to any class of weight or measure, the test of any model pertaining to such class of weight or measure shall be carried out in accordance with such procedure as would, in the opinion of the recognised laboratory, enable it to recommend the grant of certificate of approval in relation to such model.
 
### 8. Procedure for the issue of certificate of approval.—
(1) After the completion of the tests, the recognised laboratory shall send a report of its findings to the Director with its recommendations whether the model satisfies the requirements of the Act and the rules made thereunder.
 
(2) The recognised laboratory may, in an appropriate case, recommend that the approval may be accorded provisionally to enable it to conduct detailed tests and, where, in pursuance of such recommendation, provisional approval is granted, tests may be carried out on such number of instruments under such conditions of installation and use, as may be specified by the Director, and such tests may also be continued, where the recognised laboratory thinks fit so to do, in the place of use of the weight or measure, and the tests at such place of use shall be detailed ones and of such duration and carried out on such number of weights or measures as may be specified by the Director. 1[(2A) The Director may require the recognised laboratory to send to him the detailed test procedure adopted by that laboratory in approving the concerned model.]
 
(3) On examination of report made by the recognised laboratory, the Director shall, where he is of opinion that no further test is required to be carried out, submit the report to the Central Government and where he is of opinion that further tests are required, remit the report back to the recognised laboratory for carrying out such further tests; and thereupon the recognised laboratory shall, after carrying out further tests, submit a report to the Director.
 
(4) Where, after consideration of the report of the recognised laboratory, the Director is of opinion that a certificate of approval in relation to that model should be issued, it shall recommend to the Central Government the issue of the certificate and shall also forward to that Government a copy of the report submitted to it by the recognised laboratory.
 
(5) The Central Government may, if the issue of a certificate, or provisional certificate, of approval has been recommended by the Director, issue such certificate and authorise the Director to authenticate the certificate for and on behalf of the Central Government.
 
(6) No provisional certificate issued under sub-rule (5) shall remain valid for a period exceeding one year from the date of its issue: Provided that the Central Government may, if it is satisfied, on the recommendation of the recognised laboratory, it is necessary in the public interest so to do extend the period of validity of a provisional certificate for such period as it may think fit: Provided further that the Central Government may also, on an application made to it by the concerned manufacturer, extend the period of validity of the provisional certificate for such further period as it may think fit if it is satisfied that the recognised laboratory, having failed to complete the tests before the expiry of the period of validity of the provisional certificate, has unreasonably omitted to recommend the extension of such period.
 
(7) A code number shall be assigned to each approved model and the code number so assigned shall be indicated in the certificate, or provisional certificate of approval, as the case may be.
 
### 9. Procedure where issue of certificate of approval is not recommended.—
 Where the recognised laboratory does not recommend the issue of a certificate of approval in relation to any model, it shall specify its reasons therefor to the Director who shall communicate such reasons to the applicant with such directions as he may think fit and thereupon the applicant may make a representation to the Director to the effect that the issue of the certificate of approval should have been recommended by the recognised laboratory and on considering such representation, the Director may either reject it or recommend to the Central Government the issue of certificate of approval.
 
### 10. Re-submission of disapproved model for approval.—
(1) Where any model is not approved, the disapproved model may be re-submitted for approval after carrying out therein such modifications as may be necessary.
 
(2) Where any disapproved model is resubmitted for approval, it shall be deemed, for the purposes of levy of fees and tests under these rules, to be a fresh application for the approval of that model.
