ISO 680:1990 PDF Download

The ISO 680:1990 standard is focused on the chemical analysis of cement. It outlines the procedures for conducting this analysis and provides reference methods that should be followed. In some cases, alternative methods are also suggested, as long as they produce equivalent results.

This standard is applicable not only to cement itself but also to its constituent materials, including clinker and blast furnace slag. It ensures that the chemical composition of cement is accurately determined by following the specified procedures.

By providing standardized guidelines, ISO 680:1990 ensures that the chemical analysis of cement is conducted consistently across different laboratories. This helps to ensure the quality and reliability of cement products and enables fair comparisons between different types of cement based on their chemical compositions.
