JB/T 7984.4-2001 This standard is equivalent to ISO 9137:1990 "Determination of the capillary phenomenon of abrasives". This standard is a revision of JB/T 7984.4-1995 "Determination of the hydrophilicity of common abrasives". The revised measurement device and capillary time are different from the original standard. This standard specifies the determination method of the capillary phenomenon of common abrasives such as corundum and cinnabar carbide. This standard is applicable to common abrasives used in the manufacture of bonded abrasives and coated abrasives. This standard was first issued in April 1983 as GB 3605-83, and the standard number was adjusted to JB/T 7984.4-95 in April 1996. This standard is the first revision.
