Semnificație și utilizare

3.1 This test method is suitable for calculating the weight and volume of the product outlined in Section 1. The information provided in this method can be used to determine the amount of the above-mentioned aromatics in tanks, transport containers, etc.

Etapa 1: Domeniul de aplicare

1.1 This standard is used to calculate the weight and volume of benzene, toluene, mixed xylene, styrene, o-xylene, m-xylene, p-xylene, isopropylbenzene, ethylbenzene, 300 to 350°F and 350 to 400°F aromatics hydrocarbons and cyclohexane. A method for calculating the volume of 60°F from the observed volume at t °F is presented. Masa 1 lists the Vacuo densities of the chemicals used to develop this relationship at 60°F. Density (or weight) “in vacuum” represents the true density (or weight) if measured in a vacuum without the buoyancy action of air acting on a liquid. It represents the number of products that actually exist. Density (or weight) “in the air” represents what is actually measured to scale. The difference is about 0.13 percent. Modern densitometers measure density in a vacuum, and ASTM recommends using vacuum density (or weight).

Metoda de testare standard ASTM D1555-2016 pentru calculul volumului și greutății aromaticelor industriale și ciclohexanilor

(A) Regression based on the 2001 TRC Thermodynamic Table, Hydrocarbons, NSRDS-NIST 75-121 (April 30, 2001). See Appendix X1 for data.

(B) The weight was removed from the table because it was not required by the criterion. If desired, divide the 60°F density (g/cc) by 0.999016 g/cc. See Appendix X2.

(C) produced by multiplying the density at 60°F by g/cc by 8.345404452 and rounding to 4 decimal places.

(D) Use density -g/cc to produce in air ·1.000149926-0.001199407795) ·8.345404452, rounded to 4 decimal places. See Appendix X3.

1.2 Valorile exprimate în inci în lire vor fi considerate valori standard. Nu sunt incluse alte unități de măsură în acest standard.

1.2.1 A complete SI unit matching standard has been developed in test method D1555M.

1.3 Acest standard nu este destinat să abordeze toate preocupările legate de siguranță, dacă există, asociat cu utilizarea acestuia. Este responsabilitatea utilizatorilor acestui standard de a stabili practici adecvate de securitate și sănătate și de a determina aplicabilitatea restricțiilor de reglementare înainte de utilizare..
