3、e since the last revision or reapproval.1.Scope 1.1 This test method covers the determination of the amount of oil,water,and spent shale obtained upon prescribed heating of a representative oil shale sample that has been crushed to an appropriate size(2.36 mm or 8 mesh).The amount of gas evolved can
4、 be calculated from data obtained in this procedure.This test method is appli-cable to oil shale,which upon heating evolves licprid and gaseous products(Note 1).It has been tested over the range 19 to 227 L/Mg(5 to 60 gal/ton)of oil.NOTE I-The test method does not include procedures for identi-fying
5、 the nature of the gas.1.2 The test method neither yields quantities that neces-sarily duplicate yields in experimental or commercial oil-shale processes nor does it yield products that necessarily duplicate in physical or chemical nature the products that may be obtained in such experimental or com
