IP codes IP65 touchscreen display IP65 LED lamp. The IP code or ingress protection code indicates how well a device is protected against water and dust. It is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 [1] which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures ...
ISO 2281 water resistance testing of a watch consists of: Resistance when immersed in water at a depth of 10 cm. Immersion of the watch in 10 cm of water for 1 hour. Resistance of operative 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.
Meets drip and corrosion-resistance tests. 12 and 12K: General-purpose. Intended for indoor use, provides some protection against dust, falling dirt, and dripping non-corrosive liquids. Meets drip, dust, and rust resistance tests. 13: General-purpose. Primarily used to provide protection against dust, spraying of water and non-corrosive coolants.
Waterproofing, making objects or structures resist the ingress of water under specified conditions; Fluid resistance, drag in water; Lotus effect (water-resistance in plant leaves) The electrical resistivity of water (0.2 Ω·m sea water, 2 to 200 Ω·m drinking water, 180000 Ω·m deionized water at 20°C) See also: Hydrophobe; Superhydrophobe
Electrical conductivity of water samples is used as an indicator of how salt-free, ion-free, or impurity-free the sample is; the purer the water, the lower the conductivity (the higher the resistivity). Conductivity measurements in water are often reported as specific conductance, relative to the conductivity of pure water at 25 °C.
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 ...
Moisture sensitivity level (MSL) is a rating that shows a device's susceptibility to damage due to absorbed moisture when subjected to reflow soldering as defined in J-STD-020. It relates to the packaging and handling precautions for some semiconductors.
Moisture vapor transmission rate (MVTR), also water vapor transmission rate (WVTR), is a measure of the passage of water vapor through a substance. It is a measure of the permeability for vapor barriers .
