Описание (английский):

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.

Abstract

Overview

ISO 5313:1986 defines an empirical laboratory method to determine the gas oil (oil) retention of solid, high‑nitrogen, straight ammonium nitrate fertilizers. Oil retention is used as a practical measure of the material's porosity and provides a reproducible metric for quality control of prilled or granular fertilizers that contain no materials soluble in gas oil.

The method requires minimal apparatus and yields results with defined repeatability and reproducibility. It is applicable where porosity assessment supports handling, storage and product specification activities.

Key Topics

Scope: Applicable to prilled or granular high‑nitrogen ammonium nitrate fertilizers not containing gas‑oil‑soluble materials. Sample preparation follows ISO 8358.
Principle: Total immersion of a test portion in gas oil for a specified period, draining and removal of surplus oil under defined conditions, then measuring the increase in mass to calculate oil retention as a percent by mass.
Reagent characteristics: Typical gas oil properties cited in the standard include viscosity 1.3–5.0 mPa·s (1.6–6.0 cSt at 40 °C), density 0.82–0.86 g·ml⁻¹ at 15 °C; sulfur
