12、reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for w
13、hich a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
14、 matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are c
15、irculated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held resp
16、onsible for identifying any or all such patent rights. ISO 22810 was prepared by Technical Committee ISO/TC 114, Horology, Subcommittee SC 3, Water-resistant watches. This first edition of ISO 22810 cancels and replaces ISO 2281:1990, which has been technically revised. BS ISO 22810:2010ISO 22810:20
17、10(E) ISO 2010 All rights reserved vIntroduction This International Standard has been drawn up to meet a global demand for specifications for watches resistant to immersion in water and to any form of aquatic environment. This International standard is a reference. It clarifies the terms used, defin
18、es the criteria to be met by the product and specifies the marking which may appear on the product. It stipulates the tests to be applied in the event of a dispute and leaves to the manufacturer the responsibility for defining the tests (within his area of expertise) which he applies at the producti
19、on stage to his own products if he wishes to be able to guarantee that they satisfy the requirements of this International Standard. The manufacturer is responsible for stating whether a specific activity falls within the field of use of a particular watch. Similarly, he defines the warranty conditi
20、ons and the precautions to be taken to maintain the quality of the watch over an extended period of time. The notion of immersion defines a depth at which protection against water penetration is guaranteed. However, mention is made of the fact that the quality and permanent nature of the protection
21、will depend, in particular, on the sound construction of the watchcase, on the quality with which it has been made and on the products history (service actions, shocks, etc.). Annex A gives the user appropriate recommendations to ensure that use of his watch procures lasting satisfaction. Some usefu
22、l notions of physics are also included.

23、esistance of watches. Moreover, it indicates the marking which the manufacturer is authorized to apply to them. Divers watches, specified as such, are covered by ISO 6425 which establishes special requirements. 2 Terms and definitions For the purposes of this document, the following terms and defini

30、 performing the tests, the operative components of the watch are actuated and then returned to their normal position. Throughout the duration of the tests, the ambient temperature is held at between 18 C and 25 C and the water temperature is equal to the ambient temperature, except for the test desc
31、ribed in 4.3.5. 4.2 Condensation test The purpose of this test is to verify the water resistance of the watch as follows: a) place the watch on a heating plate set to between 40 C and 45 C until the watch glass reaches the temperature of the plate (in practice, the heating time varies depending on t
32、he particular watch); b) on the glass (see Note 2), place a drop of water or a wet cloth or a wet pad at a temperature between 18 C and 25 C; c) after around 1 min, wipe the glass down with a dry cloth. A watch which presents condensation on the internal surface of the glass does not satisfy the req
33、uirements of this International Standard. NOTE 1 If the watch has been closed in an atmosphere saturated with humidity, the condensation test can produce a result which is not caused by a defect in water-resistance. If that happens, the watch is dried before undergoing the condensation test again. N
34、OTE 2 For any type of glass with a thickness of more than 2 mm, the water drop condensation test is not reliable. It is therefore advisable to place a wet cloth or a wet pad onto the watch. NOTE 3 If condensation is dissipated within 1 min, it is not considered to be a water resistance defect. BS IS
35、O 22810:2010ISO 22810:2010(E) ISO 2010 All rights reserved 34.3 Water resistance tests by immersion 4.3.1 General The watch is put under strain according to the following four tests. 4.3.2 Water resistance to overpressure Immerse the watch completely in a suitable container filled with water. Raise
36、the pressure in the container in 1 min to a minimum overpressure of 2 bar. Hold it at this pressure for 10 min. Then, in 1 min, reduce the pressure back down to ambient pressure. NOTE Higher overpressure values can be specified by the manufacturer and marked on the watch. 4.3.3 Water resistance at s
37、hallow depth Immerse the watch in water to a depth of 10 cm 2 cm and keep it there for a minimum of 1 h. 4.3.4 Water resistance when strain is placed on the operative components Immerse the watch in water to a depth of 10 cm 2 cm for 5 min, while applying a force of 5 N to the crown and push-pieces
38、perpendicular to their axis (see Figure 1). NOTE If applicable, the crown and the push-pieces are screwed on. Figure 1 Examples of crown and push-pieces 4.3.5 Water resistance on exposure to thermal shocks Immerse the watch in water to a depth of 10 cm 2 cm, successively: in water at 40 C for 5 min;
39、 in water at 20 C for 5 min; in water at 40 C for 5 min. The time taken to transfer from one immersion to another shall not exceed 1 min. BS ISO 22810:2010ISO 22810:2010(E) 4 ISO 2010 All rights reserved4.4 Water resistance test by air overpressure A preliminary test may be performed on the watch. T
40、his will enable a water resistance defect to be detected without jeopardizing its integrity. Expose the watch to an air overpressure and then measure the flow rate of air penetrating into the case, successively with 2 bar and 0,5 bar. It is advisable not to perform the water resistance tests by imme
41、rsion, defined in 4.3, on watches that show a flow rate of air over 50 g/min. NOTE The air can be replaced by an inert gas. This optional preliminary test, introduced as an example, is not a substitute to the water resistance tests by immersion described in 4.3. 5 Marking 5.1 Each watch which satisf
42、ies the requirements set out in Clause 3 may be marked, depending on the language, with one of the terms shown below: in Chinese: 防水 in English: water-resistant in French: tanche in German: wasserdicht in Japanese: 日常生活用防水 in Korean: in Russian: 5.2 When the manufacturer specifies a higher overpress
43、ure than 2 bar for the test described in 4.3.2, the watch may be marked as follows: in Chinese: 防水 x bar in English: water-resistant x bar in French: tanche x bar in German: wasserdicht x bar in Japanese: 日常生活用防水 x bar in Korean: x bar in Russian: x bar where x corresponds to the overpressure applie
44、d during the test described in 4.3.2. Only whole numbers are allowed. The overpressure may be indicated in metres instead of bar.

45、haracteristics of the watch for an extended period, knowing that water resistance is not a definitive and acquired characteristic, the user is advised to: arrange for the water resistance of the watch to be checked by an expert according to the manufacturers recommendations and in every case after t
46、he watch has been opened. In this case, it is recommended that the air overpressure test be performed in accordance with 4.4; make sure, on purchasing, that the bracelet is suitable for the intended use; avoid exposing the watch to excessively sudden variations of temperature; preserve the watch aga
47、inst falls and shocks (arrange for the water resistance to be checked after every violent shock); refrain from using the control elements, push-pieces or time-setting crown under water and outside water when the watch is not dry; replace securely and screw on (if applicable) the time-setting crown a
48、nd the push-pieces after every operation; rinse the watch in fresh water after use in sea water. A.2 Notions of physics A.2.1 Overpressure When the watchcase is closed, the internal and external pressures are identical. In an air environment, the watch is exposed to atmospheric pressure which varies
49、 according to altitude and meteorological conditions. When the watch is immersed, the external pressure increases with depth, while the internal pressure continues to refer to atmospheric pressure. The atmospheric pressure augmented by water pressure is referred to as absolute pressure. The pressure exerted by the water is called overpressure. Variations of atmospheric pressure are minimum and negligible by comparison with the overpr
