After publication of BS5930:1981, the descriptive scheme for weath- ering was later criticized as being too restricted in scope and not easily applicable to a wide range of rock types and structural situations, although this was the original intention. This standard summarizes the major fields of application up to this time of each of the seven classification systems. 4.3 Using this standard, the classifier shall be able to decide which system appears to be most appropriate for the specified engineering purpose at hand.
