This document specifies a method to measure the total sulfur content in fertilizer and soil conditioner materials. This method is applicable for measuring total sulfur concentration in solid and liquid fertilizers and its raw inputs in the range of 0,1 % to 97 %.
Abstract
Overview
ISO 22887:2020 specifies a laboratory method for the determination of by . The procedure converts sulfur species to SO2 at temperatures above 1 100 °C and measures SO2 using either or detection. The standard covers both across a wide concentration range (0.1 % to 97 % w/w).
