IP67 and IP68: What does this mean for your smartphone?

IP67 and IP68: What does this mean for your smartphone?

Electrical devices are classified according to their properties using IP standards such as IP67 and IP68 for smartphones. We will explain what this means.

International Electrotechnical Commission (IEC)

Classifies equipment with an IP standard using two digits: the first describes protection against the ingress of foreign objects such as dust or sand, and the second describes protection against water. Such current models


Samsung Galaxy S21

or that


iphone 13

For example, meet IP68. But what exactly does that mean?

IP67 and IP68: This is what the numbers mean

As an overview, we have summarized all IP protection classes for both digits in a table. The number which was not measured in the respective case is always denoted by X.

Number 1: Protection against foreign objects and contact

degree of protection

importance

IP0X

no protection

IP1X

Protection against solid foreign bodies > 50 mm and against contact with the back of the hand

IP2X

Protection against solid foreign bodies > 12 mm and against contact with fingers

IP3X

Protection against solid foreign bodies > 2.5 mm and against contact with equipment

ip4x

Protection against solid foreign bodies >1 mm and against contact with wire

ip5x

Dust-proof (does not limit intrusion functions) and protection against contact

IP6X

Dustproof (no penetration possible) and contact protection

Number two: protection from water

degree of protection

importance

ipx0

no protection

ipx1

protection against falling water droplets

ipx2

Protection against water droplets falling at an angle, housing tilted up to a maximum of 15°C

ipx3

Protection against spray water, the housing should be heated to 60 degrees . can be tilted up to

ipx4

Water splash protection from all directions

ipx5

Water jet protection from all directions

ipx6

Protection against powerful jets of water and against ingress of water in the event of brief floods

ipx7

Protection against temporary, complete immersion in water (up to 1 meter depth)

ipx8

Waterproof:

Protection against continuous, complete immersion in water (up to 1 m or deeper)

(ipx9k)

Water pressure tight:

Protection against water penetration under pressure and heat up to 80 degrees

but be careful:

All degrees of protection against water are related

Especially on fresh water.

Treated water (such as chlorinated pool water) or even salt water can cause significant damage to a waterproof smartphone. For example, remember that salt water attacks the seals of equipment and makes them porous.

Smartphones with IP67 Rating

are therefore dust-proof and allow temporary (<30 min) immersion in water up to a depth of 1 m. Smartphones with IP68

are also dustproof and can even be permanently submerged to a depth of 1 meter or more. However, in both cases, any damage such as the age of the device or cracks on the housing, which may affect the protection provided, should always be taken into account.

Is IP68 better than IP67?

A smartphone with an IP68 rating is certainly less susceptible to unplanned dives and is therefore better protected. However, it does raise the question of where and for what you want to use your smartphone. The IP standard protects against accidental falls in both rain showers and toilets, so with an IP67 rating you are well prepared for everyday life.
