Suggested methods for laboratory testing of swelling rocks

A Second Series of Suggested Methods is being produced by the ISRM Commissi on on Testing Methods from 1998 onwards. In this Second Series, for each SM two versions are published: 1. A Draft SM written by the Working Group Co-ordinator(s); 2. A Final SM also produced by the Working Group Go-ordinator but with amen dments resulting from the Draft SM review by the Working Group Members and other comments received after publication of the Draft SM. A suite of the new Suggested Methods is currently being published in this J ournal. These started with an Indentation Hardness Index SM written by T. S zwedzicki and published in June 1998. Several more will be published in 199 9. However, the following SM results from a Working Group of 14 members, is al ready in the fifth draft stage and thus can be considered to be in its fina l form.
