IP-65, IP-67, IP69K? 4 Affarijiet li Għandek Taf

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. Il-Klassifikazzjonijiet tal-IP Huma Definiti minn Standard Internazzjonali

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. 

L-EWWEL DIĠIT: SOLIDI

LIVELL	DAQS TAL-OĠĠETT PROTEDAT KONTRA	EFFETTIV KONTRA
0	Mhux Protetti	L-ebda protezzjoni kontra l-kuntatt u d-dħul ta 'oġġetti.
1	>50mm	Kwalunkwe wiċċ kbir tal-ġisem, bħad-dahar tal-idejn, iżda l-ebda protezzjoni kontra kuntatt intenzjonat ma 'parti tal-ġisem.
2	>12.5mm	Swaba jew oġġetti simili.
3	>2.5mm	Għodda, wajers ħoxnin, eċċ.
4	>1mm	Ħafna wajers, viti, eċċ.
5	Protetti mit-Trab	Id-dħul tat-trab mhuwiex kompletament evitat, iżda m'għandux jidħol fi kwantità suffiċjenti biex jinterferixxi mat-tħaddim sodisfaċenti tat-tagħmir; protezzjoni sħiħa kontra kuntatt.
6	Trab Issikkat	Ebda dħul ta 'trab; protezzjoni sħiħa kontra kuntatt.

IT-TIENI ĊIFRA: LIKWIDU

LIVELL	DAQS TAL-OĠĠETT PROTETT KONTRA	EFFETTIV KONTRA
0	Mhux protett	L-ebda livell ta 'protezzjoni minn likwidu.
1	Ilma taqtir	L-ilma li jqattar (qtar li jinżel vertikalment) m'għandux ikollu effett ta 'ħsara.
2	Ilma taqtir meta inklinat sa 15-il grad	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	Ilma tal-bexx	L-ilma li jaqa 'bħala spry fi kwalunkwe angolu sa 60 grad mill-vertikali m'għandux ikollu effett ta' ħsara.
4	It-titjir tal-ilma	It-titjir tal-ilma kontra l-kompartiment minn kwalunkwe direzzjoni m'għandu jagħti l-ebda effett ta' ħsara.
5	Ġettijiet tal-ilma	Ilma proġettat minn żennuna (6.3mm) kontra l-għeluq minn kwalunkwe direzzjoni m'għandu jkollu l-ebda effett ta 'ħsara.
6	Ġettijiet tal-ilma qawwija	Ilma proġettat f'ġettijiet qawwija (12.5mm) kontra l-għeluq minn kwalunkwe direzzjoni m'għandu jkollu l-ebda effett ta 'ħsara.
7	Immersjoni sa 1m	Id-dħul ta' ilma fi kwantità ta' ħsara m'għandux ikun possibbli meta l-kompartiment ikun mgħaddas fl-ilma taħt kundizzjonijiet definiti ta' pressjoni u ħin (sa 1m ta' immersion).
8	Immersjoni 'l fuq minn 1m	L-equopment huwa adattat għal immersjoni kontinwa fl-ilma taħt kondizzjonijiet li għandhom jiġu speċifikati mill-manifattur. Normalment, dan ikun ifisser li t-tagħmir ikun issiġillat ermetikament. Madankollu, b'ċerti tipi ta 'tagħmir, jista' jfisser li l-ilma jista 'jidħol iżda biss b'tali mod li ma jipproduċi l-ebda effetti ta' ħsara.

3. Jista 'jkun hemm it-Tielet Ċifra Fi Klassifikazzjoni IP

L-ittra K hija speċifikata fid-DIN 40050-9, u mhux fl-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.

Ċifra addizzjonali, ħafna drabi ittra addizzjonali, tindika protezzjonijiet oħra li l-kompartiment għandu:

·D - Wire

·F - Oil Resistant

·H - High Voltage

·M - Device Moving During Water Test

·S - Device Standing Still During Water Test

·W - Weather Conditions
