| Alpha™ HC EP RangeSynthetic Industrial Gear OilDescriptionCastrol Alpha™ HC EP Range of lubricants (previously called Isolube EP) are a series of synthetic gear oils that exceedthe performance levels historically attributed to the traditional synthetic products that are available today. Alpha HC EPRange lubricants are formulated to provide optimum wear protection in industrial gear sets, off-highway constructionand mining applications where consistent performance is critical. Alpha HC EP Range lubricants offer a uniqueapproach to gear and system component lubrication through a focused formulation that will provide the end user withmaximum confidence in the selected application.Industry Specifications and OEM ApprovalsANSI/AGMA Standard 9005-E02DIN 51517 Part 3AIST 224AdvantagesAlpha HC EP Range lubricants’ chosen synthetic components provide the potential for extended drain intervalsand reduced maintenance costs.Alpha HC EP Range lubricants have noted viscosity range properties for low temperature fluidity and controlledvolatility.Superior rust protection.Enhanced demulsibility and hydrolytic stability.Exceptional oxidation and thermal stability.Excellent anti-wear performance.Alpha HC EP Range lubricants are formulated for off-highway construction, mining applications, and gear-sets whereextreme and harsh lubricant environments exist and performance is critical.Page: 1/2Typical CharacteristicsName Method Units 68 150 220 320 460 680Kinematic Viscosity @40°C / 100°FISO 3104 / ASTMD445 mm²/s 67.8 149.2 220.8 319.4 458.2 704.0Kinematic Viscosity @100°C / 210°FISO 3104 / ASTMD445 mm²/s 10.4 18.9 25.6 32.3 41.2 62.2Viscosity Index ISO 2909 / ASTMD2270 - 140 143 148 141 139 156Timken OK Load test ASTM D2509 kg/lb 34/75 34/75 34/75 34/75 34/75 34/75FZG Gear Scuffing test -A/8.3/90ISO 14635-1 /ASTM D5182Failure LoadStage >12 >12 >12 >12 >12 >12Pour Point ISO 3016 / ASTMD97 °C/°F -45/-49 -36/-32 -36/-32 -36/-32 -23/-9 -27/-17Flash Point - open cupmethod ISO 2592 / ASTMD92 °C/°F 227/441228/442228/442229/445229/445229/445API Gravity ASTM D287 - 35.4 33.4 33.0 32.4 31.0 35.0Specific Gravity @ 16°C /60°F ISO 3675 / ASTMD1298 - 0.848 0.858 0.860 0.863 0.871 0.850Pounds per Gallon ASTM D287 - 7.06 7.14 7.16 7.18 7.25 7.07Subject to usual manufacturing tolerances.Additional InformationWarranty and Protection RequirementsExceeds all manufacturers’ warranty requirements for applications requiring an AGMA EP, AIST 224, or DIN51524 part 3 type industrial gear oil.This product was previously called Isolube EP Range.
