Lab and Services

PakeloLab is one of the top lubricant-specific laboratories in Europe. Its main activities are diagnostics on exhausted oils and lubricant quality tests. The laboratory is managed by Pakelo Global, a society of the Group that has been harvesting a rich data bank since 1970s, which is the reference tool for diagnosis interpretation.


I.C.P. (ASTM D 5185)

Lubricants work deeply in contact with metal surfaces of mechanical components thus they incorporate all the released wear elements. The inductively coupled plasma mass spectrometry measures this content in ppm (parts per million). Resulting values estimate lubrication and mechanical parts’ conditions. This determination also helps to understand the additives depletion.

Iron – Boron – Copper – Barium – Chromium – Calcium – Aluminium – Magnesium – Lead – Sodium – Silicon – Phosphorus – Zinc

Manganese – Molybdenum – Nickel – Tin – Titanium

Viscometer (ASTM D 445)

Viscosity defines oil inner friction and it indicates the Hydrodynamic Floating Capacity. The parameter is obtained by measuring the time it takes to the lubricant to flow through a calibrated capillary.

The measure is made in a thermostatic bath at the temperature of: 40°C / 104°F – ISO 3448 Class (for hydraulic and reduction units’ oils) 100°C / 212°F – SAE J300 / J306 classifications (for engine and transmission oils)

FT-IR (ASTM E 2412)T

This sophisticated tool determines the organic composition by a Infra-Red spectroscopic analysis (Fourier Transform Infrared Spectroscopy). The instrument is equipped with a specific software for used oils analysis which applies the J.O.A.P. Method (Joint Oil Analysis Program). A single IR measurement will provide information about the level of the following parameters in the oil:

  • Water
  • Glycol
  • Fuel Contamination
  • Nitration
  • Oxidation
  • Sulfonation
  • Soot Loading
  • Anti-wear additive depletion

Particels Counting (ISO 4406/NAS 1638)

The tool allows to determine the cleanliness class (ISO/NAS) of hydraulic fluids. This parameter is essential for the correct functioning of hydraulic systems.

A laser beam projects shadow on photo diode while the electronic devices count and classify the micro particles.

TAN (Total Acid Number ASTM D664) / TBN (Total Base Number ASTM D2896)

The equipment measures both the acidity and the alkalinity by dissolution and titration. These parameters are essential to evaluate oxidation side products and residual life of engine lubricants.

Karl-Fisher (ASTM D 6304)

Karl Fisher Coulometric titration

This equipment determines water content in hydrocarbon-based fluids using a iodomoetric titration by coulometric method.

Flash Point (ASTM D 92 – D 93)

Flash point with open and closed cup

The equipment determines the minimum temperature for a product to develop a flammable mixture of air/hydrocarbons. The parameter classifies the threshold for the labelling of flammable products.

PH and Alkalinity Reserve (ASTM D 1121)

The intentional addition of hydrochloric acid measures the capability to neutralize the acidity formed by decomposition of coolant components. Glycol content is measured thanks to a specific refractive index. This parameter gives information about freezing point of the water/glycol mix.

S.R.V. (DIN 51834/ISO 19291/ASTM D 6425/ASTM D 7421/ASTM D 5707/ASTM D 5706/ASTM D 7594)

The S.R.V. (acronym of Schwingung, Reibung, Verschleiž namely Oscillating, Friction, Wear) measures the physical interactions between a lubricant and two specimens in a loaded contact in either rotational or linear oscillatory motion.

It determines the efficiency of lubricants and greases by measuring friction, anti-wear (AW) and extreme pressure (EP) properties simulating real metal to metal sliding contact.

C.C.S. (ASTM D 5293) and Brookfield (ASTM D 2983)

Cold Cranking Simulator (ASTM D5293) and Brookfield Viscometer (ASTM D2983) are used for the evaluation of apparent viscosity at low temperatures for engine lubricants (C.C.S.) according with SAE J300 or transmission lubricants (Brookfield) according with SAE J306. Lubricants pumpability at low temperatures is measured through the resistance generated by a pin dipped in the thermostat fluid at different temperatures.

HT-HS (ASTM D 4683)

HT-HS measures dynamic viscosity in extreme shear rate conditions and high temperatures. The aim of the analysis is to measure the chemical/physical properties of different lubricant solutions under extreme shear rate conditions and at different temperatures.

The instrument has been designed to best simulate working conditions in all those parts exposed to high film fluid shear rate as it is common to rings/liners and connecting rod-crankshaft/bearings

Standard conditions (ASTM D 4683): T = 150°C / Shear Rate = 1.000.000s-1

Air Release (ASTM D3427)

Air Release time

Due to mechanic shaking all lubricants entrain air: this is bad for the lubrication and for the incompressibility of the fluid. In modern hydraulic systems the decantation period is reduced and it is important to guarantee air release rapidly. The test is based on the density change measured with an electronic balance.

Foaming (ASTM D892)

The equipment and the connected test evaluate the foaming characteristics and collapse time in lubricating oils. An airflow is injected in the fluid. It is possible to evaluate the foaming tendency of engine lubricants up to 150°C and it is typically required for hydraulic fluids since this phenomenon affects the fluid compressibility.


The tool calculates weight loss measure of different molecular fraction of the lubricant (thermographic analysis). It is also suitable for the NOACK evaporable test.
It is available in connection with FT-IR instrument for the detection of the kind of evaporating substance.

Noack (ASTM D5800)

Evaporability/ Thermal-oxidative stability

NOACK equipment calculate evaporative loss by thermal stress under vacuum. It also measures the thermal-oxidative stability of base stocks and additives.

Demulsivity (ASTM D 1401)

Water separation properties

Demulsivity test determines separation time in case of intentional water contamination. Fluid is basically shaked with water and separation time from water measured.

K.R.L. – Kinematic Viscosity Relative Loss (CEC L45-T-93)

Stability to shear stress

The equipment allows to evaluate the viscosity loss of the lubricant in service due to the breaking down of molecules with high molecular weight. This phenomenon is connected with high mechanic stress.

Sonic Shear (ASTM D 5621)

Ultrasonic Shear Stability Test for hydraulic oils

In the Sonic Shear test an ultrasonic pressure wave brakes the heavy molecular components and viscosity change is measured. It is evaluated in the absolute (cSt) and relative Viscosity (%) loss.

Test 4 Ball (IP 239)

Extreme Pressure and Anti-Wear properties

In this test one of the four balls brushes on the others creating extremely high superficial pressures. Enhancing the load, the lubricating conditions get more and more challenging till the final surface melts and welds. EP properties are identified analyzing the effect of heavy loads meanwhile lighter loads for longer periods of time allow to evaluate anti-wear properties.

The capacity to bear such specific loads and the anti-welding properties are essential characteristics in particular for transmissions and hydraulic lubricants.


Analysis on Elastohydrodynamic Lubrication (Hertzian contact pressure)

E.H.L. instrument detects film thickness (in nanometers) and friction coefficients when there is deformation of surfaces on contact point. Measurement is made through an optical interferometric System. It is used in the analysis of friction modifiers’ properties, of fuel economy and for the initial formulation of high efficiency oils.

Dielectric Strength (IEC 156/CEI 10-1)

The instrument measures the dielectric/isolating properties of insulating oils investigating the minimum voltage to reach sparks trough the oil mass.

Dropping Point (ASTM D 556)

Grease’s chemical structure undergoing high temperatures is subject to peculiar changes that undermine stability. The grease sample is tested with increasing temperature ranges till drop formation. This parameter helps identifying the chemical nature of the grease and the maximum working temperature threshold.

Cone Penetration (ASTM D 217)

The consistency of the grease is measured by penetration of a standard cone into the grease. This parameter identifies NLGI Class consistency.

Pour Point (ASTM D 97)

Sliding at low temperatures

The instrument measures the minimum temperature to have fluency in tilted tubes. This parameter helps in the identification of the service temperature threshold.

  • Rotating speed: up to 20.000 rpm
  • Loading torque: up to 300 Nm
