Fly Fishing around the world

Before dipping your mobile read the guarantee

In today’s article my intention is to make fishermen aware of something very important. Many times the advertising deludes and that they do of smartphones is not different. Television ads show that promotional devices are completely watertight and can be used in conditions where water is present such as splashing, underwater, etc. Without additional protection. This is not a good idea.

Pools, rain or a phone down in the river, can become a drama. Although companies give the impression that water is not a problem for their products, the guarantee of these devices almost certainly does not cover an accident related to water and / or moisture.

Do you have a “waterproof” smartphone?

Brands such as Apple, Samsung or Sony sell mobile phones that comply with the NEMA / IEC 60529 / EN 60529 watertightness standard.

According to this standard, a device with an IP67 certificate is 100% dust resistant and supports a water immersion up to at least a depth of one meter and for 30 minutes.

IP68 is 100% dust resistant and supports a prolonged immersion in water in depth and for the time specified by the manufacturer of the product, provided that conditions are more severe than those specified for the IPX7 value.

The ads leave no doubt to the consumer, their devices are water resistant in any condition.

To reinforce this idea companies use the IP67 (or IP68) certificate, in addition to using still images in pools and water environments where the smartphone disappears under water or at least it is very humid and rescue the smartphone from the water is still working perfectly.

How are the tests performed?

The brands have not said it in their ads because the standard does not require it, the IPX7 (IPX8) certificate has been achieved in a controlled environment in a laboratory. During the test, the smartphone is not used under water and the pressure is constant at 0.1 bar, ie around 1 meter.

Over time and depending on the care and environment in which the mobile is used, after a short period of time, it is more than likely that membranes that stop the ingress of liquids and close certain elements will deteriorate. To make matters worse, tests are only done in fresh water between 10 and 30 degrees Celsius so an accident on the beach can be fatal.

Depending on the type of materials used for the housing can be deformed under pressure and water is filtered. Something similar happens between the different materials used for the screen and the different components that compose it. Also in hot water may expand differently and cause the device to lose its tightness.

A fall or heavy blow can cause the phone to lose its waterproofness.

Water with chlorine, salt and / or sweat, are liquids that attack the gaskets, the speaker, the camera and the plate of your mobile. Without additional protection, the phone suffers imminent and irreparable damage. Sun and humidity increase wear.

The ANSI / IEC makes clear that its standard 60529 is a system to classify the degrees of protection provided by the components of the electrical equipment.

This rule applies only to closure boxes which, in all other respects, are suitable for the intended use, as specified in the relevant product standard and which, from the point of view of materials and the hand of The warranty, are kept in normal use.

With the pictures fixed in swimming pools and aquatic environments where the phone disappears under water or at least is very wet and when the water rescue of the mobile phone continues to work perfectly there is no doubt the environment where mobile phones are used under normal conditions Nothing To do with the environment of a laboratory where a mobile is placed in a static situation at a depth of one meter in fresh water with a temperature between 10 ° and 30 ° Celsius.

Some brands now warn of the limitations of their “water-resistant” mobiles, after an avalanche of complaints and critical publications, some brands have posted on their websites tips on the restricted use of their devices in contact with water. These “guides”, some quite difficult to locate, are mostly a list of what can not be done with mobiles.

The lists are so long and they exclude so much that they should have announced that your “waterproof” devices should not come into contact with water or moisture.
