Digitized edition from print [produced by Natural Resources Canada]. “To provide the benefits of obtaining a measure of the percolation rate of fill that can be related to previous experience and to the practices of others, a tentative standard is proposed for use by Canadian mining companies. A draft of this tentative specification was examined by selected companies of the Mining Association of Canada which made suggestions for modifications. It is possible that further improvements can be made which will come to light after using the procedure. In this way, it is expected that the specification will evolve into a firm standard for Canada. The report includes the specifications for a Quick Test to be used for routine quality control. Specifications for a Long Test are also provided for use in special studies and research"--Abstract, p. i. Includes abstract in French. gccst Mining industry Canada. Natural Resources Canada. Canada.
