Gas analysis — Conversion of gas mixture composition data
ISO 14912:2003 defines the following quantities commonly used to express the composition of gas mixtures: mole fraction, mass fraction and volume fraction, as well as mole concentration, mass concentration and volume concentration.
Relating to these quantities of composition, ISO 14912:2003 provides methods for the conversion between different quantities and the conversion between different state…
Paints, varnishes and plastics — Determination of non-volatile-matter content
ISO 3251:2003 specifies a method for determining the non-volatile-matter content by mass of paints, varnishes, binders for paints and varnishes, polymer dispersions and condensation resins such as phenolic resins (resols, novolak solutions, etc.).
The method is also applicable to formulated dispersions containing fillers, pigments and other auxiliaries (e.g. thickeners and film-forming agents).…
Animal and vegetable fats and oils — Determination of phosphorus content — Part 1: Colorimetric meth...
ISO 10540-1:2003 specifies a colorimetric method for the determination of the phosphorus content of animal and vegetable oils and fats.
This method is not suitable for determining the phosphorus content of commercial lecithin as this requires an ashing temperature of 800 degrees Celsius.
