Waterproof?

[08FJR4ME]

So is IPX-7 water proof or water resistant? curious minds want to know.

IPX6 Waterproof Standard
Protected against heavy splashing and rain – Must not fail or show water seepage when exposed, but not immersed.

IPX-7 Waterproof Standard
Protected against short duration of water immersion. Max immersion for less than 30 minutes and at a depth of less than 1 meter. IPX-7, while water resistant is still not recommended for swimmers as a precaution.

IPX-8 Waterproof Standard
An IPX8 designation is for continuous underwater use. The best rating for sport / gps watches rated for swimming.

For non boating purposes and non high pressure hosing you can consider IPX-7 to be water proof. The following uses different terms to describe how an item may be susceptible to water.

IPX4: Splash resistant. The equipment has been splashed from all angles for at least 5 minutes at water pressure of 80–100 kN/m^2. Basically, this can handle being rained on, but if you drop it in a stream or overboard, there’s a good chance your gear won’t be working for a while, if ever.

IPX7: Immersible. This gear can be immersed for up to 30 minutes at a depth of up to 1 meter. Which means it should handle any rain or snow, and should survive falling into a creek or shallow river. NOTE: This rating does not guarantee buoyancy, so if your gear goes for a swim, it may sink deeper then 1 meter and the increased water pressure may cause a leak and damage it.

IPX8: Submersible. This equipment can handle deeper and longer submersion. The depth and time will be specified by the manufacturer based on product testing. Often IPX8 is used to describe 2 meter submersion for a period of 30 minutes. NOTE: This rating also does not guarantee buoyancy.

Whether immersion protection is needed or if splash protection is enough will depend mostly on the environment.

Copied from the Engineering Toolbox everything you wanted to know about IP ratings but had more than enough sense to ask................................... IP - Ingress Protection rating is used to specify the environmental protection - electrical enclosure - of electrical equipment


Ingress Protection (IP) ratings are developed by the European Committee for Electro Technical Standardization (CENELEC) (NEMA IEC 60529 Degrees of Protection Provided by Enclosures - IP Code), specifying the environmental protection the enclosure provides.

The IP rating normally has two (or three) numbers:

1. Protection from solid objects or materials
2. Protection from liquids (water)
3. Protection against mechanical impacts (commonly omitted, the third number is not a part of IEC 60529)

Example - IP RatingWith the IP rating IP 54, 5 describes the level of protection from solid objects and 4 describes the level of protection from liquids.

An "X" can used for one of the digits if there is only one class of protection, i.e. IPX1 which addresses protection against vertically falling drops of water e.g. condensation..

IP First number - Protection against solid objects

0 No special protection

1 Protected against solid objects over 50 mm, e.g. accidental touch by persons hands.

2 Protected against solid objects over 12 mm, e.g. persons fingers.

3 Protected against solid objects over 2.5 mm (tools and wires).

4 Protected against solid objects over 1 mm (tools, wires, and small wires).

5 Protected against dust limited ingress (no harmful deposit).

6 Totally protected against dust.


IP Second number - Protection against liquids

0 No protection.

1 Protection against vertically falling drops of water e.g. condensation.

2 Protection against direct sprays of water up to 15o from the vertical.

3 Protected against direct sprays of water up to 60o from the vertical.

4 Protection against water sprayed from all directions - limited ingress permitted.

5 Protected against low pressure jets of water from all directions - limited ingress.

6 Protected against temporary flooding of water, e.g. for use on ship decks - limited ingress permitted.

7 Protected against the effect of immersion between 15 cm and 1 m.

8 Protects against long periods of immersion under pressure.


IP Third number - Protection against mechanical impacts (commonly omitted, the third number is not a part of IEC 60529)

0 No protection.

1 Protects against impact of 0.225 joule (e.g. 150 g weight falling from 15 cm height).

2 Protected against impact of 0.375 joule (e.g. 250 g weight falling from 15 cm height).

3 Protected against impact of 0.5 joule (e.g. 250 g weight falling from 20 cm height).

4 Protected against impact of 2.0 joule (e.g. 500 g weight falling from 40 cm height).

5 Protected against impact of 6.0 joule (e.g. 1.5 kg weight falling from 40 cm height).

6 Protected against impact of 20.0 joule (e.g. 5 kg weight falling from 40 cm height).


In order to comply with the stringent requirements for CE Marking machine makers today fits their machines with parts certified according EU (European Union) and international standards.

Example - IP 22An electrical socket rated IP22 is protected against

• solid objects over 12 mm - ex. insertion of fingers
• direct sprays of water up to 15o from the vertical - ex. damage or unsafety due to vertically or nearly vertically dripping water

They are wanting confirmation that the certification at IPX7 is water resistant but not water "proof" like IPX8 certification states.

Thanks Donal,

I have been edumakated.

So IPX7 is good for heavy Rain and dust. Just don't take the Feejer swimming and I should be all set.

Good night all,

Dave

You've not being paying full attention in class. The 'X' has no implication for protection against solid objects (dust). Chances are it will be protected, but that is not specified. Please try to do better on the next test.

Mac,

Did you say "Class?" That reminds me... I'm sitting at my desk reading this, and it is indeed time for this teacher to get ready for class.

Bye for now.

What?

Something squirrelly happened to the formatting after I had posted. Done an edit, so hopefully it makes more sense now..................

We did a five hour + test [not on purpose] on a Zumo 550. The 550 was on and still working when it was retrieved from the river but died soon after that.

​On a side note, noticed my font went to 12 when the system did it's auto save thing. Had to do a little editing.
