ISO/FDIS 5313

High nitrogen content, straight ammonium nitrate fertilizers — Determination of oil retention

The result of the method is a measure for the porosity of the material. The method is applicable to substances which do not contain materials soluble in gas oil and which are prilled or granular. It consists in total immersing of a test portion in gas oil for a specified period, followed by the draining away and the removal of surplus gas oil under specified conditions, and measuring of the increase in mass of the test portion.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
