Overview

SIST EN 24935:1997 - "Steel and iron - Determination of sulphur content - Infrared absorption method after combustion in an induction furnace (ISO 4935:1989)" - is a European standard developed by the European Committee for Standardization (CEN). This standard specifies a reliable analytical procedure for determining sulphur content in steel and iron using infrared absorption after combustion in an induction furnace. The method is applicable for sulphur contents ranging from 0.002% to 0.10% by mass (m/m), ensuring accurate quality control and compliance for a wide range of metal materials.

Key Topics

Scope and Applicability

Suitable for sulphur levels between 0.002% and 0.10% (m/m).
Applicable to various forms of steel and iron, including cast iron and alloys.

Principle of Method

Test sample is combusted with an accelerator in a high-frequency induction furnace, under a stream of pure oxygen.
Sulphur in the sample is converted to sulphur dioxide gas.
The evolved sulphur dioxide is measured by an infrared absorption analyser for precise sulphur quantification.

Procedures and Equipment

Sampling according to ISO 377 or equivalent national standards.
Essential apparatus includes a high-frequency induction furnace, ceramic crucibles, tin capsules, and an infrared gas analyser.
Calibration using certified reference materials and standard solutions ensures accuracy.

Reporting and Quality Assurance

Results are expressed as a percentage by mass of sulphur.
The standard details requirements for reporting, including necessary identification details, methodology, and any deviations from standard procedure.

Additional Information

Annexes provide insights into the results of international cooperative testing, graphical representation of precision data, and features of commercial induction furnaces and infrared analysers.

Applications

Quality Assurance in Metal Production

Widely used in foundries, steel mills, and metallurgical laboratories for monitoring and certifying product composition.
Ensures steel and iron products meet industrial standards and specifications for sulphur content.

Research and Development

Supports R&D in metallurgy by providing an accurate method for determining sulphur, which influences physical properties and performance of metal products.

Regulatory Compliance

Enables compliance with national and international requirements for materials used in construction, automotive, machinery, and infrastructure projects.

Process Control

Real-time sulphur analysis improves process control and material consistency during production.
