IP Ratings Explained (IP67 vs IP68): What “Water Resistant” Really Means

GET MORE TIPS HERE

Customers hear “water resistant” and assume “waterproof.” That misunderstanding leads to damaged phones, angry returns, and warranty arguments at the counter. If you can deliver IP ratings explained in plain language—especially IP67 vs IP68—you’ll set the right expectations, protect your store, and help customers choose the right device (and protection plan) for their lifestyle.

IP Ratings Explained: What “IP” Stands For

IP stands for Ingress Protection. An IP rating is a standardized test score that tells you how well a device resists:

• Solid particles (dust, dirt, sand)

• Water exposure (splashes, rain, brief submersion)

An IP rating looks like IP67 or IP68. The two numbers mean different things.

How to Read an IP Rating (The Two Digits)

First Digit = Dust Protection (0–6)

• 6 = “Dust tight” (best rating). Dust shouldn’t get inside under test conditions.

Second Digit = Water Protection (0–9)

• 7 = Protected against temporary immersion (typically up to 1 meter for up to 30 minutes)

• 8 = Protected against continuous immersion (depth/time varies by manufacturer)

Dealer translation: The dust number is usually “6” on modern phones. The real customer question is the water number—7 vs 8.

IP67 vs IP68: What’s the Real Difference?

Here’s the simplest way to explain it:

• IP67: Tested for up to 1 meter of water for up to 30 minutes (fresh water, controlled lab conditions).

• IP68: Tested for more than 1 meter (often 1.5m to 6m) for a set time—but the exact depth/time depends on the manufacturer.

Key point: IP68 is generally “better” than IP67 for water resistance, but it’s not a universal promise. Always check the specific device’s stated depth/time.

What “Water Resistant” Really Means (and What It Doesn’t)

This is where dealers prevent returns. Water resistance is not permanent and not a guarantee.

What IP Ratings Usually Cover

• Rain, splashes, accidental drops in clean water

• Brief submersion in fresh water (within rated limits)

• Dust exposure (especially with a “6” rating)

What IP Ratings Do NOT Cover (Common Customer Mistakes)

• Saltwater: Ocean water is corrosive and can damage seals and ports.

• Chlorinated water: Pools and hot tubs can break down adhesives and gaskets.

• Soap/shampoo: Changes water surface tension and can seep into seals more easily.

• High-pressure water: Showers, faucets, jets, and pressure washers can force water inside.

• Steam/heat: Hot showers and saunas can weaken seals over time.

• Cracks and drops: One drop can compromise the seal even if the phone “looks fine.”

• Normal wear: Water resistance can decrease as the phone ages (especially after repairs).

Dealer script: “IP-rated means water resistant, not waterproof. It’s designed for accidents—not swimming, showers, or the beach.”

Why Water Damage Still Happens on IP-Rated Phones

Customers often say, “But it’s IP68!” Here’s what to explain:

• Lab tests aren’t real life: Tests use fresh water, controlled temperature, and no movement.

• Seals change over time: Heat, drops, and pocket lint can affect gaskets.

• Ports are vulnerable: Charging ports and speaker grills are common entry points.

• Repairs can reduce resistance: Screen replacements and back-glass repairs may not restore factory sealing.

Dealer tip: If a customer is buying a used/refurbished phone, set expectations that water resistance may not be the same as new—especially if it’s been opened for repair.

Dealer Best Practices: How to Set Expectations (and Reduce Returns)

• Use clear language: Say “water resistant,” not “waterproof.”

• Ask lifestyle questions: “Do you work outdoors? Around water? At a pool? On boats?”

• Recommend protection: Waterproof pouches, rugged cases, and protection plans for high-risk customers.

• Explain drying steps: If it gets wet, power it off, dry the exterior, avoid charging until fully dry, and don’t use heat (hair dryer) which can push moisture deeper.

• Document the conversation: Especially for high-risk buyers—this reduces disputes later.

Quick Customer FAQ (Dealer-Ready Answers)

• “Can I take it in the shower?” Not recommended—steam and pressure increase risk.

• “Can I swim with it?” Not recommended—movement, depth, and chemicals increase risk.

• “If it’s IP68, will warranty cover water damage?” Usually no—most manufacturers still exclude liquid damage.

• “Can I charge it right after it gets wet?” No—dry it completely first to avoid corrosion or shorting.

The Bottom Line for Wireless Dealers

IP ratings explained: IP67 vs IP68 is about tested water immersion limits under controlled conditions. “Water resistant” is designed for accidents—not intentional water use. When you set expectations clearly, you reduce returns, avoid warranty arguments, and help customers protect their devices the right way.
