experimental study
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The results were obtained from published literature source
Qualifier:
no guideline followed
Principles of method if other than guideline:
Liquid viscosities for constituents of TOPP have been obtained from a published literature. Terpenes data were available over the temperature range of 60 - 300°F. These data were extrapolated and interpolated to cover temperature region of 0 - 400°F by the correlations of Ross.
