Direct reduced iron — Determination of carbon and/or sulfur content — High frequency combustion method with infrared measurement

95.99 Withdrawal of Standard Apr 27, 2006

General information

Current stage: 95.99 Effective date: Apr 27, 2006

Originator: ISO

Owner: ISO/TC 102/SC 2

Type: International Standard

ICS: 73.060.10

Scope

The method is based on combustion of the test portion in a refractory crucible in a flow of oxygen in the presence of an accelerator, conversion of the carbon present into carbon dioxide and the sulfur present into sulfur dioxide, and measurement of each gas by infrared absorption. Applies to carbon contents between 0,05 % and 2,5 % and/or sulfur contents between 0,001 % and 0,05 % in direct reduced iron.
