ASTM D is a standard test method for vapor pressure of petroleum products. Find out more on ASTM D and their application and eralytics products. Lab Instruments · Application · Brand · Industry · Measurement · Method · ASTM · ASTM D36 · ASTM D56 · ASTM D86 · ASTM D92 · ASTM D93 · ASTM D Due to the increased use of ethanol in fuel the measurement of the Reid vapour pressure (RVP) is replaced by ASTM D in the EPA “Tier 3.

Note Samples can also be tested at other vapor-to-liquid ratios, temperatures, and pressures, but the precision and bias statements need not apply.
Calibration and verification equipment available. Determination of air saturated vapour pressure ASVP. These steps are necessary for reproducible measurements. No account is made for dissolved water in the sample.

An audible prompt sounds, when an action is required from the operator. Please see details here. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The temperature will be kept at The precision and bias statements for hazy samples have not been determined see Note The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law.
Vapour Pressure Testing of Gasoline During the measurement campaign with the process analyser the recorded vapour pressure remained in a stable region around It is based on a known volume of zstm, air-saturated sample that is introduced into a thermostatically controlled, evacuated test chamber. Test Method D, as well as IPhave been shown to be suitable for vapor pressure measurements of crude oils. Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: The pressure is automatically measured at one minute intervals, until three readings are within 0.
Use Caution when handling mercury and mercury-containing products. This reduces the need asttm manual control measurements and allows higher automation for processes where vapour pressure is a key parameter. This test method is suitable for testing samples with boiling points above 0 o C 32 o F that exert a vapor pressure between 7 and kPa 1. The crude oil measurements were performed with a Zarzaitine crude oil density: Note 3 — The interlaboratory studies conducted in, and to determine the precision statements in Test Method D did d55191 include any crude oil in the sample sets.

Work Item s – proposed revisions of this standard. The online and laboratory vapour pressure measurements of gasoline were performed at The values given in parentheses after SI units are provided for information only and are not considered standard.
Link to Active This link d519 always route to the current Active version of the standard. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials.
Make your daily satm routine a piece of cake: Also EN asym be considered as an equivalent to this method. For specific safety warning statements, see 7. By accepting cookies, you can use this website with the full range of functions and optimize your browsing experience.
However, this standard is based on a triple expansion step, which allows calculating the absolute vapor pressure of the liquid, as well as the partial pressure of the dissolved air. For simplicity, just 2 states are indicated in the line plots showing the correlation between vapour pressure and.
If a haze is observed in 8. The valves utilise solvent resistant Kalrez seals.
These may be printed via the integral RS port and optional Data Printer This can lead to uncontrollable deviations caused by the user when the sample preparation is not performed as requested by d55191 standard. The gasoline measurements were performed using a typical Austrian gasoline blend.
However, this offset was significantly lower than the reproducibility or even repeatability of ASTM D and D, as indicated in figure 4.
