AppendixIP RatingsDefinition:The first numeral defines the amount ofprotection against penetration of solid objects intothe housing.The second numeral defines the amountof protection against liquids penetrating the housing.Additional information on ratings can be foundin the following chart or the 1976 IEC Publication,Classification of Degrees of Protection Providedby Enclosures.Example: What is IP67?Complete protection of live parts. Protectionagainst the penetration of dust. Additionally,it will be protected while immersed in water.IPTesting Criteria:1. Test Class: IP67 testConditions:Test:1m head of water over the test piece for a duration of30 minutes.Room temperature ±5°CInsulation and operation2. Test Class: IP68 test (Encapsulated products)Conditions:Test:3. Test Class: IP69k testConditions:1m head of water over the test piece for 24 hours ofoperation under water, with cyclical activation anddeactivation under nominal loading Cycle time 2 hoursRoom temperature ±5°CInsulation and operationProtection against ingress of water from jets at apressure of 1450 psi and at temperatures of up to80º C. This is the level of pressure and temperaturerequired for thorough cleaning of meat, fish, poultryand dairy precessing lines.Degree of ProtectionAgainst Contact andEntrance of Solid Foreign BodiesNumeral Degree of Protection0 No protection against contactor entry of solids1 Protection against accidentalcontact by hand, butnot deliberate contact.Protection against largeobjects.2 Protection against contactby fingers.

Condensed waterfalling on housing shall have no effect.2 Protection against drops of liquid.Drops of falling liquid shall have noeffect when housing is tilted to 15°from vertical.3 Protection against rain. No harmfuleffect from rain at angle less than 60°from vertical.4 Protection against splashing from anydirection.5 Protection against water jets from anydirection.6 Protection against conditions on ships'decks. Water from heavy seas will notenter.7 Protection against immersion in waterfor the stated conditions.8 Protection against indefinite immersionin water at a specified pressure.9k Protection against high pressure, hightemperature washdownPepperl+Fuchs®Inc. • 1600 Enterprise Parkway • Twinsburg, Ohio 44087-2245 • www.am.pepperl-fuchs.comTelephone (330) 486-0001 • FAX (330) 405-4710 • E-Mail: sales@us.pepperl-fuchs.com141
