IP-65, IP-67, IP69K? 4 ting du bør vide

When searching through product specification sheets, you'll often come across an IP rating. What do those numbers mean? And what does an IP rating indicate?

1. IP-klassificeringer er defineret af en international standard

IP (or Ingress Protection) ratings are defined by the International Electrotechnical Commission (IEC) standard 60529 and are used to classify the sealing effectiveness of a particular electrical enclosure against intrusion from foreign bodies and moisture. Such foreign bodies might include hands, fingers, tools, wires, and dust. This international standard aims to provide more information rather than vague marketing terms such as "waterproof". Ingress Protection testing per IEC 60529 for lighting products can be completed by a nationally recognized laboratory and NVLAP accredited laboratories.

2. The Numbers In An IP Rating Indicate Two Meanings

The characteristic numerals in an IP rating indicated conformity with conditions summarized in the table below. The first digit designates the level of protection that a particular enclosure has against hazardous parts and the ingress of solid foreign objects. The second digit designates the protection of equipment inside the enclosure against the ingress of water. For example, an LED luminaire that's rated IP 65 is completely protected against the intrusion of dust but will become unsafe if it's immersed in water completely. 

FØRSTE CIFTER: FAST

NIVEAU	OBJEKTSTØRRELSE BESKYTTET MOD	EFFEKTIV MOD
0	Ikke beskyttet	Ingen beskyttelse mod kontakt og indtrængen af ​​genstande.
1	>50 mm	Enhver stor overflade af kroppen, såsom håndryggen, men ingen beskyttelse mod bevidst kontakt med en kropsdel.
2	>12,5 mm	Fingre eller lignende genstande.
3	>2,5 mm	Værktøj, tynde ledninger mv.
4	>1 mm	De fleste ledninger, skruer mv.
5	Støvbeskyttet	Indtrængen af ​​støv forhindres ikke helt, men det må ikke trænge ind i tilstrækkelig mængde til at forstyrre udstyrets tilfredsstillende funktion; fuldstændig beskyttelse mod berøring.
6	Støvtæt	Ingen indtrængning af støv; fuldstændig beskyttelse mod berøring.

ANDET CIFFER: VÆSKE

NIVEAU	OBJEKTSTØRRELSE BESKYTTET MOD	EFFEKTIV MOD
0	Ikke beskyttet	Intet niveau af beskyttelse mod væske.
1	Drypende vand	Drypende vand (lodret faldende dråber) må ikke have nogen skadelig virkning.
2	Drypende vand, når den vippes op til 15 grader	Vertically dripping water shall have no harmful effect when the enclosure is titled at an angle up to 15 degree from its normal position.
3	Sprøjtning af vand	Vand, der falder som en sprøjt i enhver vinkel op til 60 grader fra lodret, skal ikke have nogen skadelig virkning.
4	Sprøjtende vand	Vandsprøjt mod indkapslingen fra enhver retning skal ikke have nogen skadelig virkning.
5	Vandstråler	Vand, der projiceres af en dyse (6,3 mm) mod indkapslingen fra enhver retning, må ikke have nogen skadelig virkning.
6	Kraftige vandstråler	Vand, der projiceres i kraftige stråler (12,5 mm) mod indeslutning fra enhver retning, må ikke have nogen skadelig virkning.
7	Nedsænkning op til 1m	Indtrængning af vand i skadelige mængder skal ikke være mulig, når kabinettet er nedsænket i vand under definerede tryk- og tidsforhold (op til 1 m oversvømmelse).
8	Nedsænkning over 1m	Udstyret er egnet til kontinuerlig nedsænkning i vand under forhold, som skal specificeres af producenten. Normalt vil det betyde, at udstyret er hermetisk lukket. Men med visse typer udstyr kan det betyde, at vand kan trænge ind, men kun på en sådan måde, at det ikke frembringer skadelige virkninger.

3. Der kan være et tredje ciffer i en IP-vurdering

Bogstavet K er specificeret i DIN 40050-9 og ikke i IEC 60529.

IP ratings with the letter "K" (IP69K typically) are most prominent with food processing industries or industries where a high level of hygiene and cleanliness is paramount. IP69K provides protection against dust, high temperature, chemicals, and high pressure water. Enclosures with this rating withstand a rigorous high pressure wash-down procedure. This particular water intrusion test involves placing the product on a turntable with a rotational speed of 5 ±1 revolutions per minute. The product is then sprayed at close range at a rate of approximately 4 gallons per minute with water pressure of between 1160-1450 psi, at a temperature of 176 degree F (80 degree ). The nozzle from which the water is sprayed is held between 4 and 6 inches from the product enclosure at a variety of angles.

Et ekstra ciffer, ofte et ekstra bogstav, angiver andre beskyttelser, som kabinettet har:

·D - Wire

·F - Oil Resistant

·H - High Voltage

·M - Device Moving During Water Test

·S - Device Standing Still During Water Test

·W - Weather Conditions
