B
The permissible vapor pressures of products classified as PB mixtures must not exceed 208 psig (1430 kPa) and additionally must not exceed that calculated from
the following relationship between the observed vapor pressure and the observed relative density:
Vapor pressure, max 5 1167 2 1880 ~relative density 60/60°F! or 1167 2 1880 ~density at 15°C!
A specific mixture shall be designated by the vapor pressure at 100°F in pounds per square inch gage. To comply with the designation, the vapor pressure of the mixture
shall be within + 0 to − 10 psi of the vapor pressure specified.
C
In case of dispute about the vapor pressure of a product, the value actually determined by Test Method D 1267D 1267 shall prevail over the value calculated by Practice
D 2598D 2598.
D
An acceptable product shall not yield a persistent oil ring when 0.3 mL of solvent residue mixture is added to a filter paper, in 0.1-mL increments and examined in daylight
after 2 min as described in Test Method D 2158D 2158.
E
Although not a specific requirement, the relative density must be determined for other purposes and should be reported. Additionally, the relative density of PB mixture
is needed to establish the permissible maximum vapor pressure (see Footnote B).
F o
This method may not accurately determine the presence of reactive materials (for example, H S, S ) in liquefied petroleum gas if the product contains corrosion
inhibitors or other chemicals which diminish the reaction with the copper strip.
G
The total sulfur limits in these specifications do include sulfur compounds used for stenching purposes.
H
The presence or absence of water shall be determined by visual inspection of the samples on which the relative density is determined.
