FOREWORD

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Horology Sectional Committee had been approved by the Light Mechanical Engineering Division Council.

This standard is being published in two parts. The other part is : Part 1 Mechanical watches.

In the formulation of this standard assistance has been derived from the following publications:

a) Japan Export Inspection Standard ~- Published in 198 I.

b) Federal Decree on the Official Quality Control in the Swiss Horology Industry, Dot No. 934,ll of 18 March 1971.

c) DIN 8312 Tail 1.

5.4 The operation of switches, push buttons, mode selectors, etc, if any, shall be smooth and certain.

5.5 Digital display, if any, shall be clear and the change over shall be certain.

5.6 The alarm and chiming, if provided, shall operate properly.

5.7 The change over of the calendar hand/disc, if any, shall be certain.

5.8 Other auxilary mechanisms such as chrono- graph, timer, stopwatch eic, if any, shall function properly.

6 PERFORMANCE REQUIREMENTS The instantaneous rate of the watch/movement shall comply with the followiug minimum requirements, when measured under the conditions stipulated in 7, at the indicated temperatures.

Temperature Instantaneous Rate (s/day)

Ambient temperature 23 f 1°C High temperature 40 f 1°C Low temperature -5f 1°C

7 TEST PROCEDURE

f 1’0 Zt 2.0 $_ 3’0

7.1 The watch/movement shall be tested in DU position.

7.2 The watch/movement shall be allowed to function for a minimum period of two hours continuously before commencing the test. 7.3 The watch/movement shall be allowed to function for at least 2 hours in the stipulated temperature and shall be maintained at the respec- tive temperatures while the mesurement is taken.

7.4 The watch/movement shall be allowed to function for at least 30 minutes at the ambient temperature ( 23 Js 1 C ) between the tests at high temperature ( 40 + 1’C ) and low temperature ( - 5&l”C ) in order to avoid any risk of conden- sation and thermal shock.

7.5 The watch/movement shall be tested at the three temperatures in the sequence as given in 6.
