What is the NAS test and why is it important for special hydraulic oils?
Posted by Hamid Shakouri on 3rd Sep 2024
Within the realm of oil analysis, the
NAS (National Aerospace Standard) system serves as a tool for assessing particulate
contamination levels in the oil. This metric becomes an indicator of potential
wear and damage within machinery. The NAS system assigns a cleanliness code to
the oil, considering the quantity and size of particles present per unit volume
of fluid.The NAS code is determined by c

What are heat Transfer Oils?
Posted by Hamid Shakouri on 3rd Sep 2024
Heat Transfer Oils are oils designed to carry and transfer heat in industrial systems that require precise temperature control and are intended for use in closed indirect heating
installations. Heat transfer fluids play a crucial role in various industrial
processes and applications. They are formulated from highly refined base stocks
that are resistant to thermal cracking and chemical oxidation.

Why is Hydraulic Oil Cleanliness Important?
Posted by Hamid Shakouri on 3rd Sep 2024
Ensuring
an optimal level of cleanliness is crucial for the successful operation of
hydraulic systems in any hydraulic equipment. Contamination in hydraulic fluid
stands out as the most critical factor affecting the system's reliability, with
approximately 50 to 70% of all hydraulic system failures attributed to
contamination issues.The
ISO Cleanliness Code, ISO 4406:1987, stands out as one of the
…
What is the air-release capability of the lubricants?
Posted by Hamid Shakouri on 3rd Sep 2024
Air release refers to the
oil’s capacity to release air bubbles from the oil's bulk to the surrounding
environment. The air release test assesses the duration required for air
bubbles to ascend and exit an oil sample, conducted at a temperature of 54°C. Various
factors influence the air release outcome of oils, encompassing oil viscosity,
the molecular structure and composition of the base oil, an
