BS ISO 11599:1997

This standard BS ISO 11599:1997 Determination of gas porosity and gas permeability of hydraulic binders containing embedded radioactive waste is classified in these ICS categories:

• 27.120.20 Nuclear power plants. Safety
• 13.030.40 Installations and equipment for waste disposal and treatment
• 13.030.30 Special wastes

This International Standard describes the principles and methodologies of measuring both gas open porosity and permeability of hydraulic binder-based matrices used for immobilization of radioactive waste. The measurements can be carried out by using different apparatus designed and constructed on the basis of a few recommended characteristics. The measurements can be performed on samples prepared in a laboratory or taken from industrial production. Samples can be obtained by moulding or by coring a block.
