Viscosity Testing with ASTM D445 for Industry
Viscosity is one of the most important parameters in the characterization of petroleum products, fuel, lubricant, oil bases, crude oil, and other liquid materials. The viscosity value gives information about the characteristic of a material flow and can be an important parameter in determining product compatibility to the needs of the process or the specifications set.
PT Hidea Core Service provides a viscosity testing service with the ASTM D445 method to help quality control needs, product evaluation, material verification, and industrial technical needs.
ASTM D445 is a standard method for determining the kinetic viscosity of the petroleum fluid, both transparent and opaque fluid, by measuring the time it takes some volume of fluid to flow through due to gravity. calibrated glass capillary viscometer.
The viscosity testing became important because the appropriate vissins can relate to storage, handling, operation, as well as the characteristics of the use of petroleum products and lubricant.
Viscosity Extensive Exam with ASTM D445
For the Oil & Gas sector, energy, petrochemical, manufacturing, and the petroleum production user industry, the viscosity data becomes one parameter that can be used to evaluate material characteristics.
The viscosity testing service provides some major benefits:
- Product Pattern Pattern because of characterization
The kinematic viscosity testing provides data regarding the characteristics of material flow at a specified test state. - Support Quality Control
The test results can be used to monitor the consistency of products between batches and compare them to the valid specifications. - Petroleum Products Evaluation
ASTM D445 specifically includes the kinetic measurement of visibility on the liquid petroleum products, both transparency and opaque. - Support Lubricant Perforance Evaluation
Visciousness is an important parameter in lubricant because the operating state of the equipment can depend on the reliability of the liquid visibility used. - Support Storage and Handling
For the petroleum fuels, vistiness is one of the characteristics that can be used in estimating the conditions of storage, handling, and operational. - Data for Product Specification Evaluation
Exceptional visibility can be part of the specifications of various petroleum products.
Power Hidea Test Data Specification
As part of the service viscosity analysis serviceWell, testing can produce kinetic vision data and, if necessary, dynamic visibility is based on a relationship with density.
| Testing Parameters | Analysis Method | Units |
|---|---|---|
| Kinematic Vistolity | ASTM D445 | mm ² / s or cSt |
| Dynamic Vicosity | Calculate by Cinematic Vistoity and Density | mPa·s or cP |
| Cinematic Visciousness @ Temperature | ASTM D445 | mm ² / s or cSt |
ASTM D4445-26 uses mm ² / s as an SI unit for kinematic viscosity and mPa·s for dynamic visibility. Equivalently, 1 mm ² / s = 1 cSt and 1 mPa·s = 1 cP.
The temperature of the test should be put together as a result because viscosity is a very dependent parameter of temperature. Therefore, the results such as the Cinematic Viscosity @ 40 ° C and the Cinematic Vistoity @ 100 ° C are different data and should be interpreted based on the state of testing.
Kinematic Vistoity and Dynamic Vistolity
In viscosity testing, there are two things that are often used, which are the kinetic vicosity and dynamic vision.
Kinematic Vistolity
Cinematic visibility is a parameter determined through the timing of the fluid path through calibrated glass capillary viscometer According to ASTM D445.
The common unit used is:
mm ² / s or cSt. (centistokes)
Dynamic Vicosity
Dynamic visibility can be obtained by multiplying kinetic visibility by density:
♪ ♪
The relationship is also explained in the ASTM scope of D445.
Thus, kinetic vistiness and dynamic visibility are not two identical test results, so that the type of parameters requested need to be determined from the start as per specifications or applications.
Test Principal ASTM D445
In ASTM D445, the kinetic vistiness is determined by measuring the time it takes a number of volume of fluid to flow because gravity is going through calibrated glass capillary viscometer.
Simply put:
Sample
Because measurement is based on time, controlling the testing conditions becomes an important part of getting consistent results.
ASTM D445 is devoted mainly to a liquid that has the characteristics of Newtonian flow behavior, which is shear stress and shear rate which is essentially proportional. ASTM also noted that the material that viscosy changes significantly to shear rate can produce different results if using viscometer with different capillaries.
Why is Temperature important in the Viscosity Testing?
Temperatures are one of the most important conditions in the visonly testing. Therefore, the test results must always be seen with the temperature of measurements.
For example:
- Kinematic Vistoity @ 40 ° C
- Kinematic Vistoity @ 60 ° C
- Kinematic Vistoity @ 100 ° C
These three are results in different testing conditions.
For industrial needs, temperature information becomes important because temperature change can cause a change in viscosity characteristic. Therefore, the viscosity result should not be compared without paying attention to the temperature of testing and product specs.
Viscosity Testing Industrial Product
The viscosity testing service can be used for various materials and industrial products, according to the appropriate methods and characteristic samples.
- Fuel and Petroleum Products
Viscosity can be used as one of the parameters to evaluate fuel characteristics and support storage, handling, and operation considerations. - Lubricating Oil
Viscosity is one of the most important parameters in lubricant usage due to viscosity conformity associated with the need for equipment surgery. - Base Oil
The viscosity test can be part of characterization and quality control base oil. - Crude Oil
Viscosity can provide a characteristic data of oil crudes relevant to technical and operational evaluations. - Petroleum Products Other
Various liquid petroleum products can be evaluated based on material compatibility against ASTM D445 and valid specifications.
Viscosity Results Interpretation
The viscosity tests should not be seen as just one number. That value needs to be compared to the product specs, the temperature of the test, and the purpose of the use.
The approach of his evaluation can be made through:
Results of QC Condition Temperature Lab
For example, the result:
Kinematic Vistoity = X cSt @ 40 ° C
cannot be otherwise met or unmet without knowing the exception of a tested product.
It's important because any kind of product can have a different viscosity requirement.
With that approach, lab results report can be used as data for:
- Product Quality Verification
- Incoming Material Inspection
- Supplier Evaluation
- Batch@@
- Process Evaluation
- Quality Control
The benefits of the Viscosity Testing for Industry
The viscosity testing results can benefit in various industrial activities, among other things:
- Quality Control
Monitor visibility consistency of products between batches. - Incoming Material Inspection
Check the characteristics of the material received from the suppliers. - Supplier Verification
Compare test results to the given specifications or data suppliers. - Production Specification Verification
Make sure the viscosity results can be compared to the requirements of the valid products. - Process Evaluation
Provides material characteristic data for process evaluation needs. - Equiment and Operational Consideration
The vissins data can be one of the considerations in storage, handling, and operating conditions petroleum products.
Viscosity Testing Method Selection
The selection of test methods needs to consider material types and sample characteristics.
ASTM D445 is used for kinetic vision various liquid petroleum products. For bitumen, ASTM D445 himself directed users to consider other methods like ASTM D2170 / D2170M and ASTM D2171 / D2171M.
This shows that not all liquid materials should be automatically tested using ASTM D445.
