ISO 2281 water-resistant watches standard [edit] The International Company for Standardization (ISO) issued a requirement for water-resistant watches which likewise forbids the term waterproof to be used with watches, which many nations have actually adopted. This requirement was presented in 1990 as the ISO 2281:1990 and only designed for watches intended for ordinary day-to-day use and are resistant to water throughout workouts such as swimming for a brief period.

Nevertheless, whether they bear an extra indicator of overpressure or not, they are not intended for submarine diving. The ISO 2281 standard specifies a detailed testing treatment for each mark that specifies not only pressures however also test period, water temperature, and other parameters. Besides this ISO 2859-2 Testing plans indexed by restricting quality (LQ) for isolated lot assessment and ISO 2859-3 Tasting treatments for evaluation by qualities Part 3: Skip-lot tasting treatments worrying procedures regarding lot sampling screening entered play, considering that not every watch needs to be checked for ISO 2281 approval.

Immersion of the watch in 10 cm of water for 1 hour. Resistance of personnel parts. Immersion of the watch in 10 cm of water with a force of 5 N perpendicular to the crown and pusher buttons (if any) for 10 minutes. Condensation test. The watch shall be put on a heated plate at a temperature level in between 40 C and 45 C until the watch has reached the temperature level of the heated plate (in practice, a heating time of 10 minutes to 20 minutes, depending on the type of watch, will suffice).

After about 1 minute, the glass shall be cleaned with a dry rag.  Find More Details On This Page  which has condensation on the interior surface of the glass will be eliminated. Resistance to various temperature levels. Immersion of the watch in 10 cm of water at the list below temperatures for 5 minutes each, 40 C, 20 C and 40 C once again, with the shift between temperature levels not to go beyond 1 minute.

Resistance to water overpressure. Immersion of the watch in an appropriate pressure vessel and subjecting it within 1 minute to the rated pressure for 10 minutes, or to 2 bar in case where no additional indication is given. Then the overpressure is reduced to the ambient pressure within 1 minute.
