Test Solar B50: Parameters, ASTM Methods, and Interpretation Lab Results
Biodiesel Defaults Testing (B100 / FAME) to Support B50 Implementation
Implementation program B50 Indonesia requires biodiesel use as a 50% mixed component with solar oil. The decision of E.R. Secretary 257.K / EK.01 / ME.E / 2026 The duty of mixing biodiesel with solar oil is 50% and establishing the standard biodiesel quality used as a mixture. This decision was made on June 17th, 2026 and began to apply on July 1, 2026.
In the context of lab testing, it's important to distinguish between Biodiesel (B100 / FAME) as a mixing material and Solar B50 as a blending product. ESDM's Chair No. 257.K / EK.01 / ME.E / 2026 became the basis of biodiesel quality control before it was used in the B50 mixing process. While the final Solar B50 product specifications were set through its own regulation of the oil General Directorate and Gas Earth.
PT Hidea Core provides fuel testing services and petroleum products to help with needs quality control, verification specification, and quality evaluation before products are used or distributed.
Biodiesel Testing Parameters (B100 / FAME)
Biodiesel testing covers a number of physical characteristics, chemistry, performance and contaminant. The parameter was used to ensure biodiesel quality before it was used as a mixed component.
Physical characteristic
Some important parameters include:
- Density
- Kinematic Vistolity
- Flash Point
- System
- Cold Filter Plugging Point (CFPP)
- Colour
Physical parameters provide information about the characteristics of fuel during storage, transportation, blending and use.
Density used to know the mass kind of biodiesel at a particular temperature, whereas kinetic visibility Giving information about the characteristics of the fuel flow. Flash points are related to the characteristics of safety in handling and storage.
Burning characteristic
Cetane Number is one of the essential parameters in evaluating the characteristics of diesel fuel ignition. This value pertains to ignore quality and the characteristics of burning fuel.
Chemical characteristic
Testing also includes the characteristics of biodiesel chemistry, among other things:
- Acid Number
- Esther Content
- Iodine Number
- Oxygen Stability
- Sulfur
- Phosphorus
The parameters are used to evaluate the quality of fuel and stability during storage and use.
Gliserol and Biodiesel Component
As a FAME-based product, biodiesel quality also deals with components like:
- Monoglycerade
- Free Glycerol
- Total Glycerol
That parameter testing helps evaluate the quality of the biodiesel production process and the existence of components that can affect fuel performance.
Contaminan
Contaminan can be monitored among others:
- Water Content
- Sulfated Ash
- Carbon Residue
- Total Contamination
- Sodium + Potassium
- Calcium + Magnesium
Contamination control is important because its existence can affect the hygiene of the fuel system, the formation of deposits, and the reliability of equipment.
Testing Method
Biodiesel testing uses the standard method set in the valid specifications. The test method can come from ASTM, EN, AOCS, or SNI, depending on analysed parameters.
Some examples of methods that are generally used in biodiesel characterization include:
| Parameter | Methods Sample |
|---|---|
| Density | ASTM D1298 / ASTM D4052 |
| Kinematic Vistolity | ASTM D445 |
| Flash Point | ASTM D93 |
| Acid Number | ASTM D664 |
| Water Content | ASTM D6304 |
| Carbon Residue | ASTM D4530 |
| CFPP | ASTM D6371 |
Method selection must follow required specifications and lab testing scope that applies to those parameters.
Why is the Particle Testing Important?
The lab tests not only produce numbers, but provide information about the conditions and quality of fuel.
Density and viscosity It helps evaluate the physical characteristics of biodiesel.
Flash point Giving vital information regarding security handling and storage.
Water content used to monitor the existence of water that could increase the risk of corrosion and storage problems.
Oxygen stability Help evaluate biodiesel resistance against degradation during storage.
Acid number It can be used as an indicator of chemical change related to fuel degradation.
Meanwhile, parameters like glycerol, monoglolycerade, and ester content Giving information about the characteristics and quality of Biodiesel as the raw mixing material.
From B100 / FAME to Solar B50
Simply put, the quality control line can be described as:
Biodiesel (B100 / FAME)
↓
Test B100 Mutu
↓
Meet Specification
↓
Blending with Solar Oil
↓
Solar B50
↓
Final B50 Product Testing
Thus, B100 testing and B50 testing are Two different quality control stages..
B100 needs to meet the specification before being used as a blending component, whereas Solar B50 needs to be evaluated against the end product specification. Regulations of Dirjen Migas No. 75.K / MG.06 / DJM / 2026 specifically set the specs Solar B50 is on sale in the country.
Lab Results Interpretation
The test results should be compared to valid specification limit, not only seen based on whether the value is high or low.
For example:
Water Content
Test results are compared to the maximum required limits.
Kinematic Vistolity
Results must be within the set range for characteristic fuel flow to match.
Flash Point
Results are compared to minimum limits to making sure the safety characteristics suit the specifications.
Oxygen Stability
Results are used to evaluate fuel resistance to oxidation processes.
With that approach, laboratory reports can be used as a base to determine whether a batch meets or does not meet specifications.
Testing Applications
Biodiesel testing (B100 / FAME) can be used for needs:
- Quality control producer Biodiesel
- Incoming default material inspection
- Verify product before blending
- Quality assertion terminal blending
- Generation batch evaluation
- Verify customer specifications
- Fuel control for industry
Testing can also be part of the quality documentation in the fuel supply chain.
The test lab for B50 needs
For companies involved in the B50 implementation, testing can be done based on the quality control needs of each stage.
For B100 / FAME:
Testing is done to make sure the Biodiesel meets the specs before being used as a mixing material.
To Solar B50:
Testing is done on the blending product to ensure the final product characteristic meets the valid Solar B50 specification.
This dissemination is essential in order for the test request for the lab to be arranged according to sample types and test purposes.
