IP Code ( International’s Protection Marking)
Also called foreign body protection class (Ingress Protection Rating) or IP code (Code IP).
In most cases, everyone called “waterproof level”.
Defines that mechanical and electronic equipment can provide protection against the intrusion of solid foreign objects (including body parts such as fingers, dust, grit, etc.), liquid infiltration, and accidental contact.
What a degree of protection.

Solid particle protection
The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects.

Second digit: Liquid ingress protection
Druga cyfra wskazuje poziom ochrony, jaki zapewnia obudowa przed szkodliwym wnikaniem wody. Klasy wnikania wody nie kumulują się powyżej IPX6. Urządzenie zgodne z normą IPX7 (obejmującą zanurzenie w wodzie) niekoniecznie jest zgodne z normą IPX5 lub IPX6 (obejmującą narażenie na strumienie wody). Urządzenie spełniające obydwa testy jest oznaczone poprzez wypisanie obydwu testów oddzielonych ukośnikiem, np. IPX5/IPX7.

IPX7 = IP67, prawda?
Tak
Główna różnica między IPX7 i IP67
According to the data provided by Wikipedia, we know that 7-level Liquid ingress protection against : Immersion, up to 1 meter (3 ft 3 in) depth.
If the product’s Solid particle protection is less than 6-level, it will not be able to achieve the 7-level Liquid ingress protection.
So we can get the conclusion
IPX7 = IP67
Most of the products that have passed the IPX7 certification can easily get the IP67 certification, and you can buy with confidence when you buy related products.
So we can think at the same time:
IPX8 = IP68
IPX9 = IP69
But
IPX6 ≠ IP66
IPX5 ≠ IP65
…
Attention
But it should be noted that the waterproof machine that has passed the test can be waterproof but not soapy water and sea water, because special liquids may cause the waterproof coating to fade.
And don’t try to enter the water again if you fall the machine! No matter how small the crack is, water may seep in.
Waterproofness will also wear off over time, because waterproof rubber will age and brittle, and it may become ineffective over time.
