BS 1881-122:1983

This British Standard, a part of the BS 1881 series, specifies a method for the determination of water absorption of concrete specimens cored from a structure or precast component.

The measured absorption of each specimen is calculated as the increase in mass resulting from immersion expressed as a percentage of the mass of the dry specimen.

The water absorption test in this edition of the standard is basically unchanged from that in the 1970 edition. No estimate of repeatability or reproducibility is given in this part of this British Standard. Reference should be made to BS 5497-1 for further information on the determination of repeatability and reproducibility.
