Determination of density at 15ºC 🡄

ASTM D7777

Description: to determine the density of a sample of fuel oil at 15ºC using a portable digital density meter.

Advantages: Test in the accreditation process and under evaluation by IPAC (ISO 17025 accreditation). Results with high precision (to the nearest 1 kg/m3).


Sulphur in Petroleum and Petroleum Products by Energy Dispersive X-ray Fluorescence Spectrometry 🡄

ASTM D4294

Description: allows sulphur determination in a fuel, using portable equipment. A portion of sample is placed inside the equipment, which emits an x-ray beam originated from a sealed radioactive source, and the amount of sulphur content is automatically calculated by the device and expressed in %(w/w) or mg/kg.

Advantages: It is a clean and fast test that requires only a small amount of test sample. Test in the accreditation process and under evaluation by IPAC (ISO 17025 accreditation). High operability range: 0,01 to 5,00 %(w/w).


Water in Petroleum Products and Bituminous Materials by Distillation 🡄

ASTM D95

Description: allows the determination of water content between 0 and 25 %(V/w) by distillation of heavy petroleum products and other bituminous material.

Advantages: it is a classic method, easy to execute that allows to accurately quantify the amount of water present in a sample. Test in the accreditation process and under evaluation by IPAC (ISO 17025 accreditation).


Determination of ash in petroleum products 🡄

ISO 6245

Description: ash content consists of the inorganic residue (Va, Na, Ca, Mg, Zn, Pb, Fe, Ni) that remains after combustion of a sample in the presence of air at high temperature. These residues can occur naturally or can result from refining, or contamination during the stages of storage or distribution. This test consists of burning a small amount of sample in a controlled atmosphere, which will result in a quantifiable residue.

Advantages: it’s a gravimetric method that estimates the tendency of the material to form sediments. Test in the accreditation process and under evaluation by IPAC (ISO 17025 accreditation).


Kinematic viscosity at 50ºC

Internal Test Method

Description: viscosity corresponds to a physical property that characterizes the resistance of a given fluid to flow, as well as shear deformation. This property varies with temperature. During the test the flow of the fluid is measured, as a function of time.

Advantages: it is a simple and effective method for products with higher viscosity. It allows the determination of the kinematic viscosity at a defined temperature.


Flash Point by Pensky-Martens Closed Cup Tester

ASTM D93

Description: during the test, a sample is subjected to progressive heating, being regularly exposed to a flame. The flash point will correspond to the lowest temperature at which the sample releases enough steam to form a flammable mixture. The measurement is made using semi-automatic Pensky-Martens equipment.

Advantages: it allows to evaluate the applicability range (combustion) of the fuel and to evaluate its danger.


Free Water and Particulate Contamination in Distillate Fuels (Visual Inspection Procedures)

ASTM D4176

Description: visual test to evaluate the presence of free suspended water and contamination by solid particles in distilled fuels.

Advantages: Two test methods are used to determine the contamination of a sample. It is a rapid test to assess the presence or absence of water and particulate matter.


Determination of density at 15ºC

ASTM D7777

Description: to determine the density of a sample of fuel at 15ºC using a portable digital density meter.

Advantages: Results with high precision (to the nearest 1 kg/m3).

A portion of sample is placed inside the equipment, which emits an x-ray beam originated from a sealed radioactive source, and the amount of sulphur content is automatically calculated by the device and expressed in %(w/w) or mg/kg.

The flash point will correspond to the lowest temperature at which the sample releases enough steam to form a flammable mixture. The measurement is made using semi-automatic Pensky-Martens equipment.

Advantages: it allows to evaluate the applicability range (combustion) of the fuel and to evaluate its danger.


Determination of water content by the petroleum column method

Internal Test Method

Description: allows the determination of the water content in a range between 0 and 1 %(V/V) in distilled fuels and oils. The water content is visualised by loss of pressure in the oil column due to the release of hydrogen by reaction of a drying agent with the water present in the sample.

Advantages: Rapid method that allows the quantitative determination of the water content of a sample.


Kinematic viscosity at 40ºC using Cannon-Fenske viscometers

ASTM D445 / ISO 3104

Description: viscosity corresponds to a physical property that characterizes the resistance of a given fluid to flow, as well as shear deformation. This property varies with temperature. During the test, a Cannon-Fenske viscometer is charged with a sample and is put in a thermostatic oil bath at 40ºC. As the sample flows through the Cannon-Fenske viscometer, the time is measured in order to calculate the kinematic viscosity.

Advantages: it is a test that determines the kinematic viscosity at a defined and stable temperature. The test uses international standards (ISO or ASTM) that allow the determination of values within a range of 5 to 700 mm2/s (cSt).


X-ray fluorescence spectrometry: Monitoring the presence of metals and elements

Internal Test Method

Description: this test method can monitor the presence of wear metals (for example V, Ni, Na, Ca), present in samples of petroleum products by the X-ray Fluorescence (FRX) technique. A portion of the sample is placed inside the equipment, which emits an x-ray beam originated from a sealed radioactive source, and the amount of sulphur content is automatically calculated by the device and expressed in mg/kg.

Advantages: allows quick monitoring of the presence of metals and elements in the sample. To the end-user, it will allow greater control over the product’s characteristics to identify equipment degradation and reducing maintenance costs.
