Title
Standard Practice for Preparation of Liquid Blends for Use as Analytical Standards
ASTM International
Publication Date:
Nov 10, 1999
Scope:
This practice covers a laboratory procedure for the preparation of
small volumes of multicomponent
liquid blends for use as analytical standards.
This practice is applicable to components that are normally liquids at
ambient temperature and
pressure, or solids that will form a solution when blended with
liquids. Butanes can be included if
precaution is used in blending them.
This practice is limited to those components that fulfill the
following conditions:
They are completely soluble in the final blend.
They are not reactive with other blend components or with blend
containers.
The combined vapor pressure of the blended components is such that
there is no selective
evaporation of any of the components.
The butane content of the blend is not to exceed 10 %. (Warning:
Extremely flammable liquefied gas
under pressure. Vapor reduces oxygen available for breathing.)
Components with a vapor pressure
higher than butanes are not to be blended.
The values stated in SI units are to be regarded as the standard.
This standard does not purport to address all of the safety concerns,
if any, associated with its
use. It is the responsibility of the user of this standard to
establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
