ISO 680

ISO 680 refers to a viscosity grade for industrial lubricants. It is part of the ISO VG (Viscosity Grade) classification system developed by the International Organization for Standardization (ISO) to standardize the viscosity of lubricating oils.

ISO 680 corresponds to a viscosity range of 612-748 centistokes (cSt) at 40°C (104°F). Lubricants with this viscosity grade are typically used in heavy-duty industrial applications, such as large gearboxes, circulating oil systems, and hydraulic systems, where high load carrying capacity and wear protection are required.

It is important to note that ISO viscosity grades do not indicate the performance or quality of a lubricant, but rather its viscosity at a specific temperature. Other factors such as base oil type, additive package, and application requirements should also be considered when selecting a lubricant.
