Difference Between IP67 and IP68
The ip67 and ip68 have the same gasket, the differences are the internal protection around logic board connectors. For example, the IP67 logic board connectors have a foam pad with adhesive on one side, while the IP68 features a uniform large foam pad (vs individual connectors) with adhesive on both sides.
IP is the name of the standard that was drawn up by the International Electrotechnical Commission (IEC) to determine how resistant an electrical device is to fresh water and common raw materials – like dirt, dust, and sand.
The IP68 version means the ingress protection is dust tight (number 6) just like our IP67 gasket strip. The number 8 means that it is suitable for continuous immersion in water, meaning that the gasket strip is hermetically sealed and can be immersed underwater for a certain amount of time.
Why Are They Important?
IP67 – Protects phone from immersion in water at a depth of up to 1 meter (or 3.3 feet) for up to 30 mins
IP68 – Protects phone from immersion in water at a depth of more than 1 meter. In this case, the manufacturer must specify the exact depth.
What About Other Liquids?
Let’s be clear here: the rating the IEC assigns is strictly for fresh water. That means it doesn’t guarantee protection from submersion in other liquids such as beer, coffee, salt water, and soda.
According to Apple’s definition, all models from the iPhone 6s to iPhone X Plus are splash, water, and dust resistant, and were tested under controlled laboratory conditions with a rating of IP67 under IEC standard 60529. Splash, water, and dust resistance are not permanent conditions and resistance might decrease as a result of normal wear, such as placing in your pocket or leaving out in the sun. Because of that, Apple’s warranty for water-resistance doesn’t cover liquid damage as they do not guarantee the device will maintain its rating through its life.
Why Should You Re-Install the Gasket?
This is actually a conversation every technician should have with their customers before repairing a phone. Not only because it’s a matter of integrity – we believe every fixed phone should be returned to its original state with all retaining plates, screws, gaskets, and foam pads – but we also believe it’s important to protect the technician from future complaints that might hurt their business reputation and/or pocket.
When discussing a repair with a customer, explain the overall process in addition to what they should watch out for in the future. When it comes to the gasket, explain that this should maintain the phone’s water resistance, but it’s no longer a guarantee (frame damage may impede a proper seal). In the end, looking out for your customers and remaining transparent will pay forward in a big way.
