ASTM Table 54B. (Extracts or complete) Gives the conversion factor of volumes and densities as a function of the density at 15 ° C. Applies exclusively to refined petroleum products. It applies between temperature and density limits at 15 ° C, that is : Density kg/m3 ° C. 653 à 778-18 à 95. 778 à 824-18 à 125. 824 à 1 075 -18 à 150.
What is table 6A in ASTM 54B?
TABLE 54B (Products). TABLE 6A (Crude Oil). TABLE 6B (Products). Weighted Average temperature calculated. DRY DENSITY CALCULATION. PARTIAL WET DENSITY CALCULATION. ASTM 6 A - Tafel or Routine. ASTM 6 B - Tafel or Routine. SP.
How to evaluate density @ 15 deg C using ASTM?
You have to draw a composite sample of crude or product and measure the sample for Temperature and Density and use ASTM Table 53, to evaluate Density @ 15 Deg C. In Table 53, Vertical side you have Sample Temperature and horiontally Sample Density and the corresponding value is Density @ 15 Deg C.
What is table 6A on the table 6b?
TABLE 6A (Crude Oil). TABLE 6B (Products). Weighted Average temperature calculated. DRY DENSITY CALCULATION. PARTIAL WET DENSITY CALCULATION.
What is the use of ASTM Table 54?
ASTM Table 54 stands for evaluating VCF (Volume Correction Factor). On vertical side Tank Temperatures are given and horiontally Density @ 15 Deg C are given. Corresponding value for Tank Temperature and Density @ 15 Deg C is VCF.
What are ASTM tables?
ASTM tables give the Volume correction factors (VCF) to find the volumes at temperature for which the density is given.
What are we using the ASTM Table 53a B for?
Allows to determine the density at 15 ° C, directly from the density observed at the temperature of the product measured, using a densimeter for petroleum products (calibrated at 15 ° C). Gives the conversion factor of volumes and densities as a function of the density at 15 ° C.
How do you calculate weight correction factor?
We know, GSV x Density in Air = Weight in Air (MT). GSV x Density in Vacuum = Weight in Vacuum (MT). This is called Weight Correction Factor (WCF).
What do the ASTM numbers mean?
ASTM's designation system for metals consists of a letter (A for ferrous materials) followed by an arbitrary sequentially assigned number. These designations often apply to specific products, for example A548 is applicable to cold-heading quality carbon steel wire for tapping or sheet metal screws.
Why are ASTM standards used?
ASTM standards are crucial in evaluating the material, chemical, mechanical, and metallurgical properties of metals. This information helps guide product manufacturers toward proper processing and application procedures.
Why is density measured at 15 C?
Since the density of a liquid varies as its temperature changes, the scale is adjusted to a certain temperature, usually about 15 degrees C., at which determinations must be made.
How do you use volume correction factor?
What's the volume correction factor when converting gas units to...Take a meter reading.Subtract the new meter reading from the previous read to work out the volume of gas used.Multiply by the volume correction factor (1.02264)Multiply by calorific value (40.2)Divide by kWh conversion factor (3.6)
How do you calculate corrected density?
The density of fuel should be corrected using an appropriate temperature correction factor obtained from ASTM Petroleum Table 54B or equivalent or computer software incorporating these tables or the formula: Corrected density = Density (in the air) at 150C X [1- {(T0C – 150C) X 0.00065}], where T0C is the temperature ...
What is the formula of correction factor?
Correction Factor (CF) = 100/50 = 2.
What is the correction formula?
FS = R - W/(K - 1) FS= "corrected" or formula score. R= number of items answered right. W= number of items answered wrong. K = number of options (alternatives ) (same for all items).
Why do we use correction formula?
The Finite Population Correction Factor (FPC) is used when you sample without replacement from more than 5% of a finite population. It's needed because under these circumstances, the Central Limit Theorem doesn't hold and the standard error of the estimate (e.g. the mean or proportion) will be too big.
What are the 5 types of standards recognized by ASTM?
ASTM stands for the American Society for Testing and Materials and has created six types of standards that relate to manufacturing processes such as testing, materials classification and operation. The six types are test method, specification, classification, practice, guide and terminology standards.
What does ASTM mean in steel?
American Society for Testing MaterialsOriginally called the “American Society for Testing Materials” in 1902, it then became the “American Society for Testing and Materials” in 1961 before it changed its name to “ASTM International” in 2001.
How many ASTM standards are there?
Over 12,800 ASTM Standards operate globally. Defined and set by us, they improve the lives of millions every day.
What is ASTM test method?
ASTM test methods are petroleum industry standards, accepted worldwide for quality and reliability. ASTM test methods for petroleum and refined products include: Petroleum and Petrochemical Test Directory. ASTM Tests for Petroleum, Fuels and Petrochemicals.
