Methodology for PCF Calculations of Lubricants, Greases and other Specialties
Scope for PCF calculation
The scope for PCF calculation includes the definition of the declared unit and the reference flow (cf. Section 2.3.1). Moreover, the considered product system is defined (cf. Section 2.3.2), including the defined system boundaries (cf. Section 2.3.3).
2.3.1 Declared unit and reference flow
The declared unit is the production of 1 kg of unpacked lubricant or other speciality at the factory outbound gate. Likewise, the reference flow is defined as 1 kg of unpacked lubricant or other speciality at the factory outbound gate1.
An example of the declared unit could be the production of 1 kg of unpacked automotive engine oil (SAE 0W-20) at the outbound factory gate of the lubricant manufacturer.
The lubricants or other specialities for which this methodology applies can be, for instance, grouped into:
• Automotive Engine Oils • Automotive Transmission and Gear Oils • Automotive Antifreeze and Coolants • Industrial Gear Oils • Hydraulic Oils • Compressor Fluids • Anticorrosion Fluids • Metalworking Fluids • Marine Lubricants • Greases and Pastes • Thermal Fluids • Bio-based lubricants • Food-grade lubricants • Textile lubricants • Turbine Oils • Transformer Oils
1 Note: Internal calculation through, e.g. ERP systems might require a change of magnitude of unit (e.g. change of unit to tons) to avoid losing accuracy.
