ISO 10427-3:2003 describes testing practices to evaluate the performance of cementing float equipment for the petroleum and natural gas industries.ISO 10427-3:2003 is applicable to float equipment that will be in contact with water-based fluids used for drilling and cementing wells. It is not applicable to float equipment performance in non-water-based fluids.
