An indication of the test pressure in terms of water depth does not mean a water-resistant watch was designed for repeated long-term use in such water depths. For example, a watch marked 30 metres water resistant cannot be expected to withstand activity for longer time periods in a swimming pool, let alone continue to function at 30 metres ...
Water volume: 12.5 litres per minute Pressure: 30 kPa (4.4 psi) at distance of 3 meters (9.8 ft) 6 Powerful water jets Water projected in powerful jets (12.5 mm (0.49 in)) against the enclosure from any direction shall have no harmful effects. Test duration: 1 minute per square meter for at least 3 minutes Water volume: 100 liters per minute (0 ...
Waterproofing conducted on the exterior of a freeway tunnel. Waterproofing is the process of making an object, person or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions.
Water resistance may refer to: The WR mark on a wristwatch indicating its ability to withstand exposure to water; The IP code on a mechanical or electrical enclosure indicating its ability to resist the ingress of water; Wet strength, a measure of the strength of paper when wet
The testing of the water-resistance is fundamentally different from non-dive watches, because every watch has to be fully tested. Besides water resistance standards to a minimum of 100-metre depth rating, ISO 6425 also provides eight minimum requirements for mechanical diver's watches for scuba diving (quartz and digital watches have slightly ...
Water resistance is measured by the amount of water, in mm, which can be suspended above the fabric before water seeps through. [ citation needed ] Breathability or moisture vapor transmission rate is measured by the rate at which water vapor passes through, in grams of water vapour per square meter of fabric per 24-hour period (g/m 2 /d), [ 2 ...

Cement boards may be classified as water resistant as they are not affected by water exposure; however, they do allow penetration and passage of water and water vapor. To waterproof cement boards, a liquid or membrane waterproofing material is applied over its surface. Cement boards should not be confused with gypsum core backer boards.
